Full textAbstract:
Conversion is a transformation altering worldviews and identities through changed awareness of self, community (including religion, society, politics, economics and industry) and global ecology. The guiding principle of Laudato si’ by Pope Francis is contained in several points, “Everything is related”, relies on scientifical findings: life on Earth’s current forms depend on natural equilibriums. Biodiversity collapse and global warming are two deteriorations which deeply threaten the humanity survival. Christian tradition offers some precious assets to face this emergency, and become committed, as a Christian, in ecological causes: Ecological conversion is essentially a return to the realization of God’s will in the matter of caring for one’s home.

Full textAbstract:
AbstractThe field of ecological immunology currently relies on using a number of immune effectors or markers. These markers are usually used to infer ecological trade-offs (via conflicts in resource allocation), though physiological nature of these markers remains elusive. Here, we review markers frequently used in insect evolutionary ecology research: cuticle darkening, haemocyte density, nodule/capsule formation, phagocytosis and encapsulation/melanization via use of nylon filaments and beads, phenoloxidase activity, nitric oxide production, lysozyme and antimicrobial peptide production. We also provide physiologically based information that may shed light on the probable trade-offs inferred when these markers are used. In addition, we provide a number of methodological suggestions to improve immune marker assessment.

Full textAbstract:
Molecular cloning from DNA fragments of improved RAPD amplification of Angelica sinensis, Angelica acutiloba and Levisticum officinale, provided novel sequence-characterized amplified region (SCAR) markers A13, A23, Al-34 and Al-0 whose sequences were deposited in the GenBank database with the accession numbers KP641315, KP641316, KP641317 and KP641318, respectively. By optional PCR amplification, the SCAR markers A13 and A23 are Levisticum officinale-specific, whereas the SCAR marker Al-34 is Angelica acutiloba-specific, and the SCAR marker Al-0 is Angelica sinensis-specific. These diagnostic SCAR markers may be useful for genetic authentications, for ecological conservation of all three medicinal plants and as a helpful tool for the genetic authentication of adulterant samples.

Full textAbstract:
Microsatellite markers remain an important tool for ecological and evolutionary research, but are unavailable for many non-model organisms. One such organism with rare ecological and evolutionary features is the epizoic barnacleChelonibia testudinaria(Linnaeus, 1758).Chelonibia testudinariaappears to be a host generalist, and has an unusual sexual system, androdioecy. Genetic studies on host specificity and mating behavior are impeded by the lack of fine-scale, highly variable markers, such as microsatellite markers. In the present study, we discovered thousands of new microsatellite loci from next-generation sequencing data, and characterized 12 loci thoroughly. We conclude that 11 of these loci will be useful markers in future ecological and evolutionary studies onC. testudinaria.

Full textAbstract:
The aim of the research is to examine the relationship between the integral parameters of respiratory function, the values of LPO-AOD system and NO level at bronchopulmonary pathology in individuals living in different ecological areas of the city of Vladivostok. 206 patients living in different ecological conditions (healthy individuals, patients with respiratory disorders) were examined. Lung function and the state of LPO-AOD system were studied; the concentration of NO metabolites was assessed in blood serum. The nature and strength of the impact of environmental factors on respiratory function, the state of LPO-AOD, NO level were studied by the method based on correlation analysis. There was calculated power index (D) which was differentiated into power within the system (Ds) which in its turn reflects the in-system interrelationship tension (LPO-AOD, respiratory) and power between systems (Dm) characterizing the activity of interconnections and response to an external stimulus. Intra-system dependences typical for the unfavorable zone were viewed in relation to the favorable zone. It was found out that in ecologically unfavorable regions in individuals with different bronchopulmonary pathologies the value of Ds increases. This indicates that the pathogenic influence of environmental factors increases. In healthy people living in ecologically unfavourable area physiological adaptive-compensatory reaction of the body was revealed, which was proved by high power interconnections (Dm). In the patients with chronic bronchitis there was maintained an adequate level of functioning of the body systems studied. In patients with COPD living in an unfavourable zone there were found strong links between the indicators of the system of LPO-AOD and of NO, and in patients with bronchial asthma - supplementary relationship between lung function and NO. At the same time pathologic changes in the system of LPO-AOD and NO depend on the general pollution, metal and gas components contained in the air. Thus, the people with respiratory diseases being in environmentally unfavorable conditions have the most negative influence. The analysis of the activity of relationships proved that violations of interaction of LPO-AOD systems and NO in ecologically unfavorable regions may contribute to the occurrence and progression of bronchopulmonary diseases.

Full textAbstract:
Maize Research Institute ?Zemun Polje? genebank maintains a collection of landraces grouped into 18 agro-ecological collected from ex-Yugoslavia territories. The application and comparison of different marker systems are important for the characterization and use of maize landraces in breeding program, as potential sources of desirable traits. In this study, 15 morphological traits, 7 RAPD primers and 10 SSR primer pairs were applied to i) to determine genetic distance between 21 maize dent landraces and ii) compare results obtained on morphological and molecular markers. Phenotypic analysis showed high level of heterogeneity between landraces. Higher level of genetic diversity was obtained with SSR than with RAPD. Genetic distance mean value for RAPD data was 0.35 i.e. for SSR 0.48. Based on the morphological traits and molecular markers, unweighted pairgroup method (UPGMA) analysis was applied for cluster analysis, using statistical NTSYSpc program package. Cluster analysis of morphological and molecular markers distances did not show the same population grouping. Better agreement with agro-ecological data was obtained with RAPD markers. Correlations between dissimilarity matrices for different types of markers were low. Data obtained in this work could be useful for further study of a larger number of landraces, and conservation of genetic resources and their genetic diversity.

Full textAbstract:
There is an ever-increasing need to enhance the capability of sensor technology for health, structural and environmental monitoring. One area of great concern is new strains of microbial organism and the spread of infectious diseases that requires rapid identification and detection in vivo and in vitro. Another area of major concern, worldwide, is the threat of chemical and biological terrorism. This points out onto necessity of improovement of existing and development of novel detection technologies based on nanomaterials. Nanophotonics-based sensors utilizing nanostructured multiple probes provide the ability for simultaneous detection of different biomedical and ecological objects as well as the ability for remote sensing where necessary. A useful future approach can utilize nanoscale optoelectronics with hybrid detection methods involving both photonics and electronics.

Merrill, Keith R. "Usage and Development of Molecular Markers for Investigation of the Population and Ecological Genetics of Bromus tectorum L." BYU ScholarsArchive, 2011. https://scholarsarchive.byu.edu/etd/2955.
Full textAbstract:
This thesis includes two studies: The first examined patterns of neutral genetic diversity within Bromus tectorum L. across the IMW region, and uses patterns of microsatellite (SSR) genotype distribution to make inferences about the respective roles of adaptively significant genetic variation, adaptive phenotypic plasticity, and facultative outcrossing in the ongoing invasion and recent range expansion of B. tectorum. It has been previously demonstrated that, due to extremely low outcrossing rates, it is possible to characterize individual genotypes of this species using four SSR loci. We sampled 20 individuals from each of 96 B. tectorum populations (classified by region and habitat) from throughout the IMW and used these SSR markers to characterize each individual. We found 131 four-locus SSR genotypes; however, the 14 most common genotypes collectively accounted for 79.2% of the individuals sampled. Individuals with certain SSR genotypes sorted strongly into warm or salt desert habitats (stringent habitats) and flowered earlier than individuals with genotypes from more mesic habitats, providing evidence of adaptively significant genetic variation associated with these genotypes. Other SSR genotypes were found across a wide range of habitats though they tended to be less prevalent in stringent habitats, providing evidence that adaptive phenotypic plasticity may be important for the distribution of some common genotypes. We observed very few heterozygous individuals, consistent with the highly inbreeding reproductive strategy of B. tectorum. Because specialist genotypes dominating recently invaded areas within the IMW region contained unique alleles, they are not likely to have resulted from recombination, leading us to doubt the role of facultative outcrossing as a significant mechanism facilitating the current range expansion of B. tectorum in the IMW.Previous research investigating the population and ecological genetics of Bromus tectorum L. in the North American invaded range has relied on either allozyme or microsatellite (SSR) genetic analyses, both of which have proven to have shortcomings. In order to overcome the issues associated with these other marker types, in the second study of this thesis we developed single nucleotide polymorphism (SNP) markers for B. tectorum by 1) obtaining normalized cDNA, 2) sequencing normalized cDNA using 454 sequencing, 3) aligning resultant contigs and looking for SNPs, 4) designing assays for SNP validation and genotyping using KASPar, 5) converting working KASPar assays for use with the Fluidigm EP1 platform using the 96.96 Dynamic ArrayTM IFC. Sequencing resulted in 1258041 reads, which assembled into 65486 contigs (20782 large contigs exceeding 500 base pairs). Using selection criteria of at least 10x coverage and 30% of the minor allele, 3333 putative SNPs were identified. We developed KASP assays for 255 putative SNPs, which resulted in 101 working polymorphic assays. Ninety-six assays were then successfully converted for use with KASP on the Fluidigm EP1 genotyping platform using 96.96 dynamic arrays.

Full textAbstract:
The larger grain borer (LGB) Prostephanus truncatus (Horn) is the most important pest of farm stored maize and cassava in Africa. This alien invasive species was introduced into the continent from Mesoamerica in the late 1970s and by 2008 had spread to at least 18 countries. In contrast to indigenous primary storage pests, LGB exists as on-farm and as wild populations, hence, sustainable control must target both environments. Biological control is especially attractive for wild populations to reduce early season grain store infestation, while cultural and chemical methods are useful to protect stored produce directly. Two populations of the predator Teretrius nigrescens Lewis were introduced into several African countries' as a biocontrol agent. It has shown long-term success and cost effective control in warm-humid areas. Control has however not been successful in cool and hot-dry zones. The aim of this study was to investigate the possible underlying genetic and ecological explanations for these observations and the possibility of joint use of molecular markers and ecological parameters in the development of sustainable control strategies. A 28-month baseline monitoring and recovery activity was done in from 2004 in five regions in Kenya along an east-westerly transect. Monitoring and live sample collection was also done in the original outbreak area in eastern Kenya. There was greater LGB flight activity in western Kenya (high potential maize production area) than the low potential areas. Very few T. nigrescens were recovered, solely in the eastern regions. LGB flight activity followed a seasonal pattern mostly related to changes in the relative humidity at 12:00, rainfall and dew point temperature but with a 3 - 4 week lag. A linear predictive model based on these factors predicted 27 % of the observed flight activity. The survival and predation of five strains of T. nigrescens were compared at eight temperature levels between 15 °C and 36 °C at low and high humidity. All the strains of T. nigrescens exerted a significant reduction of LGB population build-up between 21 °C and 33 °C with generally better performance under humid conditions. There was no evidence of T. nigrescens development at 15 °C. At 18 °C, T. nigrescens oviposition and development was observed but the effect on LGB did not differ significantly from the control. The KARI population was the least effective in preventing grain damage at lower temperatures, but performed better than other strains above 30 °C at low humidity conditions. There was no control at 18 °C and 36 °C under both high and low humidity conditions. Since the extent of genetic differentiation in T. nigrescens was unclear from prior studies, several molecular marker techniques were progressively used. The RAPD-PCR did not reveal any genetic diversity between geographical populations. A 1000bp region of the mitochondrial mtCOI gene revealed two distinct clades differing consistently at 26 segregating sites. The two clades can be identified by simple PCR-RFLP procedure using single or double sequential restriction with EcoR1, HincII, RsaI and DdeI digestion. However, the two lineages co-exist among the mid-altitude Central American populations. The internal transcribed spacer regions ITS1 and ITS2 with some neighbouring coding sequences of the ribosomal DNA were cloned and sequenced. The spacer regions were so variable in length and sequence between T. nigrescens and related Histeridae species that direct sequence alignment was not meaningful. Within T. nigrescens, there was intragenomic variability of the spacer regions mostly involving insertions and deletions of variable tandem repeat units predominantly within the ITS regions. The short flanking coding (18S, 5.8S and 21S) regions were conserved across populations and six other Histeridae species. There was no significant secondary structure variation of the ITS regions among populations of T. nigrescens. Twenty-four novel variable microsatellite markers were developed and tested on the Honduras populations. Alleles per locus ranged between two and twelve with observed heterozygosity between 0.048 and 0.646. Six loci deviated significantly from Hardy Weinberg Equilibrium and possibly had null alleles. The success of microsatellite amplification in outgroup species and variability of markers declined with an increase in the phylogenetic distance between the test species and T. nigrescens. Genotyping 432 individuals from 13 geographic populations revealed a comparatively higher genetic diversity in field populations. Partial isolation by distance and time was observed. Population bottlenecks were not detected, but recent expansion was evident in laboratory populations. Although five dominant genetic clusters were identified by Bayesian methods, meaningful hierarchical population structure was observed at between two and nine population groups (p < 0.01; 10,000 iterations). Biological control of the larger grain borer using T. nigrescens seems an important aspect of the sustainable integrated control approach of the pest. Ecological adaptations, appropriate release strategies and genetic diversity are all essential considerations in these efforts and could be responsible for the variable success already observed. There is some genetic differentiation between populations of T. nigrescens but, further studies would be necessary to ascertain the contribution of such diversity to its predatory performance. The effect of laboratory culturing in aggravating genetic drift should be accommodated to avoid loss of diversity during sampling, quarantine, rearing and release of the predator.<br>Thesis (Ph.D. (Environmental Science))--North-West University, Potchefstroom Campus, 2009.

Full textAbstract:
Cetaceans have historically been object of heavy exploitation, and are still currently subject to different threats. For conservation and management purposes, most of the large cetacean populations have been categorized in stocks, considered as isolated and demographically independent management units. Many research techniques may contribute in the definition of these stocks, such as morphometric studies, mark recapture studies, genetics, satellite tracking. This thesis focuses on the development and application to cetacean populations of chemical markers of geographical origin and spatial movements. The main objective of the thesis is to evaluate the potentialities of chemical markers, such as stable isotopes and element concentrations, to investigate the patterns of distribution, the level of structuring and, when possible, the migration routes, of cetaceans populations. All these variables are essential to ensure the implementation of proper management measures and to guarantee the conservation of these animals. Three case studies were considered: the Eastern North Atlantic sperm whale (Physeter macrocephalus); the South Western Atlantic right whale (Eubalaena australis), and the North Atlantic fin whale (Balaenoptera physalus). δ15N, δ13C and δ18O values were analyzed in the dentinal growth layers of sperm whales from Denmark and NW Spain, in bone of right whales from Southern Brazil and Northern Argentina, and in bone of fin whales from W Iceland and NW Spain; concentrations of fluoride and selected metals (Zn, Pb, Ti, Sr, Cu) were analyzed in bone of fin whales from W Iceland and NW Spain. To establish the validity of each marker, the degree of compliance of each of the following four properties has been investigated: i) the basal levels of the chemical marker in the environment present significant gradients; ii) the chemical marker can be detected and measured in the tissues of whales; iii) the variability of the chemical marker within each population is moderate or, alternatively, it is predictable through measurable parameters, so that its effect can be taken into account; and iv) the values of the chemical marker in the body tissues reflect basal levels in a predictable and consistent manner. Each marker provided, at different levels, valuable information regarding the studied populations. Some difficulties emerged, connected with the complexity of the migratory cycles of whales, the possible intervention of homeostatic regulation mechanisms, and the characteristics of the tissues investigated. Nevertheless, results highlighted the occurrence of structuring within the North Atlantic sperm whale population, as well as within the South Western Atlantic right whale population, which are both currently considered as a single management unit. Moreover, results regarding the North Atlantic fin whale populations contributed to highlight the complexity of migration patterns and of the level of connectivity among the currently accepted stocks, challenging the proper definition of their limits and their degree of isolation within the basin. Some further research is recommended to deepen the knowledge about the North Atlantic fin whale population structure, as well as to investigate the levels of chemical markers in other tissues with different turnover characteristics, such as skin or baleen plates. Overall, the results obtained from the analyses performed in this thesis underline the power of chemical markers as a complementary tool to the traditional techniques used for investigating the structure and demography of cetaceans’ populations.<br>Los cetáceos han estado y están actualmente sujetos a diferentes tipos de amenazas. Para su correcta gestión y conservación, la mayoría de las poblaciones de grandes cetáceos han sido categorizadas en “stocks”, considerados como unidades de gestión aisladas y demográficamente independientes. Muchas técnicas de investigación pueden contribuir en la definición de estas unidades, como los estudios morfométricos, los estudios de marcaje y recaptura, la genética y el seguimiento por satélite. El objetivo principal de esta tesis es evaluar las potencialidades de los marcadores químicos, tales como los isótopos estables y las concentraciones de algunos elementos, como herramientas para la investigación de los patrones de distribución y del nivel de estructuración de las poblaciones de cetáceos. Para ello, se han considerado tres casos modelo: el cachalote del Atlántico Nororiental, la ballena franca del Atlántico Suroccidental, y el rorcual común del Atlántico Norte. Se analizaron las proporciones isotópicas de δ15N, δ13C y δ18O en muestras de dientes de cachalote y de hueso de ballena franca y rorcual común; y las concentraciones de flúor y de metales pesados (Zn, Pb, Ti, Sr, Cu) en muestras de hueso de rorcual común. Cada marcador proporcionó, a diferentes niveles, información valiosa sobre las poblaciones estudiadas. Al interpretar los resultados, surgieron algunas dificultades relacionadas con la complejidad de los ciclos migratorios de los cetáceos, la posible intervención de mecanismos de regulación homeostática, y las características de los tejidos investigados. Sin embargo, los resultados destacaron cierto nivel de estructuración dentro de las poblaciones de cachalotes del Atlántico Norte y de ballenas francas del Atlántico Suroccidental, que actualmente están ambas consideradas como unidades de gestión únicas. Por otra parte, los resultados obtenidos en las poblaciones de rorcual común del Atlántico Norte contribuyeron a evidenciar la complejidad de los patrones migratorios y del nivel de conectividad entre sus poblaciones, desafiando la adecuada definición de sus límites y de su grado de aislamiento. En general, los resultados de la tesis destacan las potencialidades de los marcadores químicos como herramienta complementaria a las técnicas utilizadas tradicionalmente para la investigación de la estructura y demografía de las poblaciones de cetáceos.

Previous issue date: 2018-03-08<br>Os Sert?es, from Euclides da Cunha, enjoys wide recognition by part of the literary criticism and it is considered one of the most representative books of Brazilian literature. That occurs, mostly, due to the its subject matter, the War of Canudos, and the way the author has built his narrative, allowing the book to be studied through various fields of knowledge. The prestige of ?Os Sert?es? reveals itself in the interest it has aroused in readers outside Brazil, resulting the translation to various languages, among them Spanish, which was the first foreign language to which the book was translated. This dissertation aimed at performing a study on the Cultural Markers present in Da Cunha?s book Os Sert?es (1984[1902]) as well as investigating how those CMTs were translated to Spanish (SANTOS, 1980). The research starts with a discussion on the writing process of the book, highlighting the contacts and the research sources of the author, setting up his works and his critical fortune, such as Santana (1995), Valente (2007; 1996), Galv?o (1977; 1981; 1984), Medeiros (2009), among others. Then, it was discussed the vocabulary of Euclides Os Sert?es, starting from some studies already done (GALV?O, 1985; SANTOS, 1980; ZACHARIAS, 2001). The theoretical- methodological cutout was done from notions, definitions and concepts of Corpus Linguistics and Translation (BAKER, 1993; SARDINHA, 2002; 2004; CAMARGO 2007; 2008), Cultural Domains, Cultural Markers (NIDA, 1945; AUBERT, 2006a; 2006b; 2008; CAMARGO, 2008; e REICHMAN; ZAVAGLIA, 2014) and Translation Modalities (AUBERT, 1998; 2006a; 2006b). Based on the precepts of Corpus Linguistics, it was compiled a paralleled corpus formed by the Portuguese version of Os Sert?es and its translation to Spanish in order to search for the CMTs candidates and their respective translation components. For the corpus treatment and analysis, it was used, in this investigative work, some computer softwares, mainly the WordSmith Tools 7.0, their tools and utilities like Concord, Keyword, Wordlist, Text convert and Aligner. The results were the compilation of 95 Cultural Markers from the Portuguese version of the book, their Spanish translation correspondents and the identification of the Translation Modalities. Those data were organized in lexicographic files, created to this end, and which present definition and subscriptions. Those data served as a parameter for the analysis, which turned out to be a trend in the use of one single type of Translation Modality for the Cultural Markers with sporadic possibilities of variation, causing the use of only one variable in the translation of those lexical unities, in general, with a little possibility of variation.<br>Os Sert?es, de Euclides da Cunha, disfruta de amplo reconhecimento por parte da cr?tica e ? considerado um dos livros mais representativos da literatura brasileira. Isso ocorre, principalmente, por conta do tema tratado na obra, a Guerra de Canudos, e o modo como o autor construiu a sua narrativa, permitindo que o livro possa ser estudado por v?rias ?reas do conhecimento. O prest?gio d?Os Sert?es revela-se tamb?m no interesse que despertou em leitores fora do Brasil, resultando na tradu??o para diversos idiomas, dentre eles, o espanhol, que foi a primeira l?ngua estrangeira para a qual foi traduzido. O trabalho em quest?o teve como objetivo principal realizar um estudo dos Marcadores Culturais (MCs) no livro Os Sert?es de Euclides da Cunha (1984 [1902]) e investigar como esses MCs foram traduzidos para a l?ngua espanhola (SANTOS, 1980). Iniciamos a pesquisa com uma discuss?o sobre a escrita da obra, destacando os contatos e as fontes de pesquisa do autor, situando os trabalhos de sua fortuna cr?tica, tais como: Santana (1995), Valente (2007; 1996), Galv?o (1977; 1981; 1984), Medeiros (2009) dentre outros. Em seguida, tra?amos uma discuss?o sobre o vocabul?rio de Euclides da Cunha e d?Os Sert?es, partindo de alguns estudos j? feitos (GALV?O, 1985; SANTOS, 1980; ZACHARIAS, 2001). O recorte te?rico-metodol?gico foi feito a partir das no??es, defini??es e conceitos de Corpus Lingu?stico e Tradu??o (BAKER, 1993; SARDINHA, 2002; 2004; CAMARGO 2007; 2008), Dom?nios Culturais, Marcas e Marcadores Culturais (NIDA, 1945; AUBERT, 2006a; 2006b; 2008; CAMARGO, 2008; e
REICHMAN; ZAVAGLIA, 2014) e Modalidades de Tradu??o (AUBERT, 1998; 2006a; 2006b). Pautado nos preceitos da Lingu?stica de Corpus, compilou-se um corpus paralelo formado pela obra Os Sert?es em portugu?s e sua tradu??o para o espanhol para buscar os candidatos a MCs e seus respectivos correspondentes de tradu??o. Al?m do corpus paralelo, foi elaborado um corpus de refer?ncia para verificar a chavicidade destes candidatos. Para an?lise e tratamento do corpus, utilizou-se, nesta investiga??o, alguns programas computacionais, principalmente, o WordSmith Tools 7.0, suas ferramentas e seus utilit?rios como o Concord, Keyword, Wordlist, Text convert e Aligner. O resultado foi a compila??o de
95 Marcadores Culturais da obra em portugu?s, seus correspondentes de tradu??o em espanhol e a identifica??o das Modalidades de Tradu??o. Estes dados foram organizados em fichas lexicogr?ficas, criadas para este fim, as quais apresentam tamb?m as defini??es e as abona??es. Esses dados serviram de par?metro para a an?lise, que demonstrou uma tend?ncia no uso de um ?nico tipo de Modalidade de Tradu??o para os Marcadores Culturais com possibilidades espor?dicas de varia??o. Ocasionando o uso de apenas uma vari?vel na tradu??o destas unidades l?xicas, de uma maneira geral, com pouca possibilidade de varia??o.

Full textAbstract:
The central theme of this book is ecological and territorialist conversion as a strategic response to the crisis. 'The return to the territory' can be conceived as a valorisation of the common heritage of assets (environmental, urban fabric, landscape, socio-cultural) that mould the identity and lifestyles of every place on the earth. This calls for several issues to be addressed: the fusing of fragmented knowledge into a science of the territory that addresses the problems of socio-territorial and environmental decay in an integrated manner; the definition of new markers and policies of public welfare and happiness, including the landscape as a measure of the quality of peoples' life-worlds; the boosting of tools of local democracy and supportive federalism; the restoration of centrality to the rural world in the production of healthy food, hydro-geological protection measures, ecological reclamation, urban and landscape quality and integrated economies.

AbstractIn the 2016 Volume 2 of the Satoyama Initiative Thematic Review (SITR), a summary of the activities of the Grani Antichi Association in Montespertoli, Tuscany, was introduced with a roll out plan for transformative change of the supply chain and possible replication of the project in other regions. The main goal of the project has been to restore and preserve ancient varieties of wheat, cultivate them sustainably and include a form of payment for the least compensated members of the production chain. The aims of the Association are to reduce the carbon footprint of modern agricultural practices and the landslides and soil erosion caused by them, to preserve biodiversity and most importantly, to improve farmers’ revenue, enabling them to safeguard the environment and improve health by cultivating healthy food. The preservation of social ties and local knowledge is an additional result. Markers of the project’s success include benefits that are equally distributed across the production chain, farmers who are motivated to cultivate ancient wheat varieties and the conversion of 500 ha of abandoned or conventionally cultivated land to a more sustainable and biodiverse system. The market economy system in place was dismantled, and farmers now have access to more economic benefits, which must be distributed fairly. Because the project provides a transformative model of production and consumption outside the traditional market economy system, it appears to function with a complete multi-sectoral chain, where producers, food processors and consumers agree on a set price for a defined product. This chapter provides a preliminary analysis of the successes and challenges related to the main project and to upscaling in different areas.

Full textAbstract:
AbstractEnergy and fatigue carry important implications for vitality and overall quality of life. Lacking energy and experiencing fatigue can be both burdensome as well as adaptive. This chapter first classifies energy and fatigue and then reviews their measurement. This chapter closes with opportunities for future directions.Energy and fatigue are present under varying conditions including in daily performance, during and after acute physical or mental strain (capacity), and in the context of chronic conditions. Energy and fatigue have been measured both subjectively and objectively. Subjective outcomes can be derived from self-reported scales and prompts; objective outcomes may be derived from performance and capacity tasks and technology-reported physiological, biological, and behavioural markers. The scales and tasks employed to measure energy have been traditionally validated but may lack daily life context and ecological validity. Prompts and behavioural monitoring methods are emerging as promising alternatives.Energy and fatigue have also been routinely monitored for specific diseases and occupations. However, fewer studies monitor healthy individuals through consumer technology in daily life contexts. More research is needed for an objective, unobtrusive, longitudinal, and contextual measurement of energy and fatigue in the healthy general population, in service of improving health, wellbeing, and quality of life.

Solving the problem of supply the population with food products during the boom period of global demographic directly depends on agriculture and the least essentially depends on land resources and environment. Coming out of it, finding out the natural management topics of agricultural development is especially urgent in Autonomous Republic of Ajara, which is one of the regions of Georgia with land scarcity, where in line with establishment of land`s private property and market economy, due to irrational natural management � a serious ecological problems are shaped in agricultural field. By application of traditional and modern study methods, geographic originalities of quantitative and qualitative properties of the land resources are evaluated. There are determined a field structure of agriculture, indicators of manufacture, natural management topics of agricultural development and related ecological problems. As a result of a study, main trends of agricultural production are defined by taking into account the basic principles of rational natural management, requirements of internal and external markets and environment`s ecological sustainability.

Full textAbstract:
The article investigates the influence of Kazakhstan�s law enforcement agencies on local communities in the 1920s and 1930s within the context of state-driven confiscation policies and sustainable resource management, demonstrating how these agencies emerged as powerful instruments for implementing governmental directives. This era is marked by extensive political repression and profound social transformations, which enforced the forced expropriation of lands, resources, and means of production. Such interventions disrupted established economic practices and social structures, leading to substantial shifts in the livelihood systems of the population and destabilizing their long-term resilience. The relevance of this research lies in its potential to inform contemporary strategies by critically examining historical precedents. Specifically, it underscores the need to develop modern frameworks for state engagement with local communities, as well as principles for sustainable development that uphold the rights and interests of these populations. The primary aim of this study is to analyze the underlying causes and consequences of repressive policies, the roles and functions of law enforcement bodies in executing these policies, and to evaluate the long-term impacts, including resource depletion and ecological degradation. The findings indicate that confiscation policies introduced novel social and environmental challenges, complicating local communities' capacity for adaptation. This analysis highlights the importance of historical insights as a basis for crafting approaches that promote both environmental sustainability and social welfare. Utilizing lessons from past state-community interactions can guide more effective, balanced policies that foster economic stability while ensuring sustainable community development and ecological integrity.

Full textAbstract:
С точки зрения комплексного междисциплинарного подхода, для повышения продуктивности сельскохозяйственных культур необходимо применение достижений генетико-селекционного характера. В работе приведены примеры эколого-генетических подходов и генетических инструментов маркерной помощи селекции, основанных на статистических методах и подходах. In addition to remote sensing technologies, an integrated interdisciplinary approach wins in solving plant productivity problems. Therefore, the aspects of ecological and genetic achievements in the field of plant breeding, the interaction of selection with classical, quantitative and molecular genetics are added to the technologies of accurate farming, cloud services for managing agricultural production and so on. One of the tools that ultimately affects the production of cultivated plants, which allows predicting the behaviour of the genetic parameters of a plant population under changes in ontogenetic, ecological and cenotic conditions for the formation of quantitative plant characteristics, are ecological-genetic algorithms for increasing the productivity of a plant. Ecologicalgenetic approaches to the successful solution of the problems of genetic selection are presented. In turn, molecular genetic studies have established the existence of individual key genes (quantitative trait loci), which contribute to the formation of a certain quantitative trait, although the measure of this contribution is regulated by the external environment. Such genetic loci constitute the main interest of the modern molecular approach to the selection of polygenic plant characteristics, including marker selection assistance. Such conditions are genetic mapping using molecular markers and the use of created maps for the analysis of associations of marker attributes is a step in the implementation of selection of auxiliary markers. Without accurate, statistically verified information about such associations and the processes of building genetic maps, it is impossible to carry out a marker-auxiliary selection, which in turn is expected to contribute to the acceleration of the selection process, including the creation of new varieties with the desired characteristics.

Full textAbstract:
The article identifies relations between the design of the Centro Cultural São Paulo (1975-1982) by Eurico Prado Lopes and Luiz Telles, with a new sensibility that emerges from the sixties onwards, driven by criticism of the consumer society, the energy crisis of seventies and the growing ecological awareness. From the identification of these relationships, theoretical and disciplinary propositions by Vittorio Gregotti, Kenneth Frampton and Stan Allen are summoned and discussed as markers of changes in design concepts and postures that progressively incorporate environmental concerns and sustainability issues. Some projects that demonstrate the parallelism of this ecological awareness in Brazil and abroad are selected and the multiple faces of its expression in contemporary architecture are analyze.

Full textAbstract:
The ability to maintain an appropriate level of vigilance over long periods of time underlies success on a range of tasks. Particularly, staying alert allows to detect infrequent signals and to allocate the right level of cognitive resources to respond to expected or unexpected events. A review of literature shows that some physiological markers can assess this variation of attention in a lot of lab studies. These findings are interesting for human factors in aeronautics as it appears as a way to characterize and quantify the observation during assessment with pilots in a cockpit simulator. The objective of this present study is to integrate a set of physiological metrics in a representative cockpit and to test their robustness in a more ecological environment with the associated constraints. This paper presents the first step of this project with a series of two lab experiments where we tested physiological markers of vigilance proposed in the literature.We first explored these markers in a psychomotor vigilance task (PVT) classically used in the study of vigilance. ECG (Heart Rate Variability or HRV), oculometrics (blink frequency, Percentage of Eye Closure or Perclos, oculomotor pattern) and EEG (alpha rhythm) were collected. The results show an increase in reaction time over time, which indicates a decrease in vigilance. They also confirm the relevance of HRV, Perclos and Alpha rhythm as a metrics of change in vigilance. In contrast, blink frequency did not appear to correlate with vigilance in our task. We then applied the relevant metrics to a second task that combined an alarm detection task and a supervisory task, the objective being to observe the robustness of the device for a task closer to the operational context. Subjective reports and changes in performance appear to reflect a decline in alertness over time. Interestingly, HRV and Perclos also seem sensitive to these changes in vigilance, but not Alpha rhythm (which could be related to the presence of noise in the signal as well as to the small number of participants). The results obtained demonstrate that the combination of ECG and eye-tracking indicators is a promising solution for the investigation of pilot vigilance in a cockpit simulator.

Full textAbstract:
The main problem of wheat immunity to leaf rust is the loss of efficiency of most Lrgenes. The decrease in efficiency is associated with microevolutionary processes within the population and the emergence of new virulent phytopathogen races that can overcome previously efficient resistance genes. The article presents the results of the phytopathological test and marker analysis of the selected material of winter wheat for resistance to the leaf rust pathogen (Puccinia recondita Rob.ex Desm f. sp. tritici.). The object of the research was 20 cultivar samples of various ecological and geographical origins. DNA was isolated from the leaves of 10-day-old wheat germs. Molecular markers were used for the following genes: Lr9 (SCS5), Lr10 (Fi.2245/Lr10-6/r2), Lr19/Sr25 (SCS265), Lr20/Sr15 (STS638), Lr24/Sr24 (Sr24#12), Lr34/Sr57 (csLV34), Lr37/Sr38/Yr17/Pch2/Cre5 (Ventriup/LN2), Lr41 (GDM35), Lr47 (PS10). Using molecular markers, the studied wheat varieties did not reveal the highly and partially effective genes Lr9, Lr19/Sr25, Lr24/Sr24, Lr41, and Lr47 in Russia, and the ineffective gene Lr20/Sr1. As a result of molecular screening, it was found that the List 25 variety had Lr37 genes; the Mif variety had Lr10 genes; the Eltan variety had Lr10 genes; the Markola variety had Lr34 genes; the Malvina variety had Lr26 genes; the Tvorets variety had Lr10 genes; the DB 1/05 variety had Lr10 genes; the Evklid variety had Lr10 genes; the Sumai aut variety had Lr34 genes; the Lebidka odes'ka variety had Lr34 genes; the Solara variety – Lr34; the Zhiva variety – Lr10, Lr34. When comparing the results of marker analysis with field resistance to leaf rust, the resistant type of reaction to infection (R) was shown by the cultivars: Battum, Eltan, Evklid, Areal, and Solara; the susceptible type of reaction (S) was noted in the cultivars Markola and Mallyska; the medium susceptible type of reaction (MS) – in the cultivars Lebidka odes'ka and Tvorets.

Full textAbstract:
The present study was a two-part investigation into the concept of, risk markers for, and original measure of Cannabis-Dependent Appetite (CDA). Cannabis-Dependent Appetite is a condition in which some prolonged heavy cannabis users develop disordered eating habits, marked by the increasing need for cannabis ingestion to stimulate appetite. Current literature is mainly focused on changes in appetite post-ingestion. However, it is imperative to differentiate changes in appetite solely after use and changes in appetite both during sober and intoxicated periods. This distinction targets the disordered eating habits characteristic of CDA. Participants (N = 60) were 18 years or older and were cannabis users. In the first portion of the study, 11 risk markers (family and personal history of mental health disorders, number of daily sessions, frequency, form quantity, anxiety, depression, anxiety sensitivity, affectivity, difficulty in emotion regulation, and age of onset) were analyzed as potential predictors of the development of CDA, which is measured using the Cannabis-Dependent Appetite Measure (CDAM). In the second portion, participants (N = 40) from the first portion who were daily cannabis users, had a smartphone, had access to reliable internet or data, and were willing to receive text messages from the research team were included in the daily collection of self-reported eating and cannabis use habits. Within-subject correlations between times when eating and cannabis use occurred were calculated and correlated with scores on the CDAM as a way to validate that the CDAM measures the behaviors aimed at assessing. It was hypothesized that individuals who use cannabis more frequently (vs. less frequently) are more likely to develop Cannabis-Dependent Appetite (CDA) as potential risk markers (family and personal history of mental health disorder, number of daily sessions, frequency, form quantity, anxiety, depression, anxiety sensitivity, negative affectivity, and difficulty in emotion regulation) increase and others (age of onset and positive affectivity) decrease. Frequency (r(55) = .49, p < .001, r2 = .24), average number of daily sessions (r(55) = .45, p < .001, r2= .20), and quantity of cannabis concentrates (r(29) = .41, p = .024, r2= .16) were significantly positively associated with Cannabis-Dependent Appetite. Both age of onset (r(57) = -.29, p = .031, r2 = .08) and positive affectivity (r(60) = -.44, p < .001, r2 = .19) were significantly negatively correlated with CDA. A significant positive correlation was found between being high and eating (r(38) = .37, p = .018, r2 = .14). Data show the behavioral trends assessed using Ecological Momentary Assessment add validity to the CDAM.

Full textAbstract:
This report provides an overview and summary of the Muskoxen and Genomics in the Community (MAGIC) Workshop held in Cambridge Bay, Nunavut in January 2024. The workshop brought together Inuit Knowledge Holders, hunters, and decision makers, scientists from a variety of disciplines and international participants. Together the group considered Inuit knowledge of and priorities for muskoxen, scientific knowledge and gaps, and the potential for genomic and DNA-based tools to help secure a viable future for muskoxen in the face of multiple climate-related stressors. Indigenous Knowledge combined with application of novel scientific advances, such as whole genome sequencing (WGS) of target organisms and use of DNA-based molecular ecological tools (such as environmental DNA markers for species detection from the soup of DNA molecules found within environmental samples), and consideration of the broader ecosystem offers the opportunity to change the way in which healthy wildlife populations are sustained.

In future, hydropower plants will need to produce more electricity. Glacial melting is creating the conditions to establish new reservoirs while further potential is also offered by heightening dam walls. However, from an economic perspective, the sector as a whole is suffering. New economic approaches are therefore required and, at the same time, greater attention must be paid to ecological considerations.

Sunny, Yemuna. Redefining Sustainable Development: Co-Creation of Knowledge with the Bharia People. Indian Institute for Human Settlements, 2023. http://dx.doi.org/10.24943/tesf0706.2023.
Full textAbstract:
This study examines the lived experiences of the Bharia people of Patalkot with regard to ecology, society, and the modern school. The research methodology, attempting to keep the agency of the Bharia at the centre, has helped to evolve knowledge that is at once embedded and questioning. At the interface of the tribal and the non-tribal existences, like the market and the modern school, there are undercurrents of exploitation, alienation and a sense of being undervalued. The thriving forests of Patalkot enhance socio-cultural and ecological relationships of tribal society and help rethink development in terms of ecological restoration and egalitarian relationships, both of which are in decline in the contemporary phase of capital through liberalisation, globalisation and privatisation.

Full textAbstract:
This summary discusses the need to implement green and progressive taxes in Latin America and the Caribbean in response to a triple planetary crisis that includes climate change, biodiversity loss, and water scarcity, exacerbated by marked regional inequalities. It argues that the region must lead tax reforms that address these challenges comprehensively, proposing specific taxes on the wealthiest and environmentally harmful practices. It emphasises the urgency of acting in a coordinated manner at both regional and global levels to ensure socio-ecological transitions that reconcile economic and social well-being with environmental sustainability, within a framework of justice and equity.

Full textAbstract:
This Groundwork investigates the sustainable practices and conservation efforts of forest-dwelling communities in the Cherangani and Kakamega forests of Kenya, emphasizing the complex and often conflicting dynamics that shape their relationship with the environment. These communities, deeply rooted in traditional ecological knowledge, are under growing pressure to balance their cultural heritage with modern conservation strategies imposed by external stakeholders. Tensions arise as they attempt to sustain their livelihoods—relying on forest resources for food, medicine, and income—while facing challenges such as land tenure insecurity, restrictive government policies, and the encroachment of commercial interests. At the core of these tensions is the trade-off between immediate survival needs and long-term ecological sustainability, with conservation measures sometimes marginalizing local groups or conflicting with indigenous knowledge systems. External economic pressures, including agricultural expansion, logging, and market demands, further exacerbate these challenges, leaving communities caught between preserving their ecosystems and responding to external forces that threaten both their environment and their way of life.

Full textAbstract:
The Southeast Coast Network (SECN) conducts long-term terrestrial vegetation monitoring as part of the nationwide Inventory and Monitoring Program of the National Park Service (NPS). The vegetation community vital sign is one of the primary-tier resources identified by SECN park managers, and it is currently conducted on 15 network parks (DeVivo et al. 2008). Monitoring plants and their associated communities over time allows for targeted understanding of ecosystems within the SECN geography, which provides managers information about the degree of change within their parks’ natural vegetation. 2019 marks the first year of conducting this monitoring effort on four SECN parks, including Timucuan Ecological and Historic Preserve (TIMU). A total of 23 vegetation plots were established in the park in May and June. Data collected in each plot include species richness across multiple spatial scales, species-specific cover and constancy, species-specific woody stem seedling/sapling counts and adult tree (greater than 10 centimeters [3.9 inches (in)]) diameter at breast height (DBH), overall tree health, landform, soil, observed disturbance, and woody biomass (i.e., fuel load) estimates. This report summarizes the baseline (year 1) terrestrial vegetation data collected at Timucuan Ecological and Historic Preserve in 2019. Data were stratified across three dominant broadly defined habitats within the park (Coastal Plain Nonalluvial Wetlands, Coastal Plain Open Uplands and Woodlands, and Maritime Upland Forests and Shrublands) and three land parcels (Cedar Point, Theodore Roosevelt, and Thomas Creek). Noteworthy findings include: A total of 157 vascular plant taxa (species or lower) were observed across 23 vegetation plots, including nine species not previously known from the park. Three plots were located in the footprint of the Yellow Bluff Fire, and were sampled only two weeks following the fire event. Muscadine (Muscadinia rotundifolia), cat greenbrier (Smilax glauca), water oak (Quercus nigra), and swamp tupelo (Nyssa biflora) were the most frequently encountered species in Coastal Plain Nonalluvial Wetland habitat; saw palmetto (Serenoa repens), slash pine (Pinus elliottii), and gallberry (Ilex glabra) were the most frequently encountered species in Coastal Plain Open Upland and Woodland habitat; and Darlington oak (Quercus hemisphaerica), Spanish moss (Tillandsia usenoides), and red bay (Persea borbonia) were the most frequently encountered species in Maritime Upland Forests and Shrublands. There were no exotic species of the Florida Exotic Pest Plant Council list of invasive plants (FLEPPC 2020) observed on any of these plots. Both red bay and swamp bay (Persea palustris) were largely absent from the tree stratum in these plots; however, they were present (occasionally in high abundance) in the seedling and sapling strata across all habitat types. Buckthorn bully (Sideroxylon lycioides)—listed as Endangered in the state of Florida by the Florida Department of Agriculture and Consumer Services (FDACS 2020)—was observed in three Maritime Upland Forest and Shrubland plots. The tree strata in each broadly defined habitat were dominated by the following species: Coastal Plain Nonalluvial Wetlands-loblolly bay (Gordonia lasianthus) Coastal Plain Open Uplands and Woodlands-longleaf pine (Pinus palustris) Maritime Upland Forests and Shrublands-oaks (Quercus sp.) Most stems within the tree strata exhibited healthy vigor and only moderate dieback across all habitat types. However, there was a large amount of standing dead trees in plots within Maritime Upland Forests and Shrublands. Downed woody biomass (fuel loads) were highest in the Cedar Point and Thomas Creek land parcels.

Full textAbstract:
This paper introduces biofuels sectors as energy inputs into the GTAP data base and to the production and consumption structures of the GTAP-Energy model developed by Burniaux and Truong (2002), and further modified by McDougall and Golub (2008). We also incorporate Agro-ecological Zones (AEZs) for each of the land using sectors in line with Lee et al. (2005). The GTAP-E model with biofuels and AEZs offers a useful framework for analyzing the growing importance of biofuels for global changes in crop production, utilization, commodity prices, factor use, trade, land use change etc. We begin by validating the model over the 2001-2006 period. We focus on six main drivers of the biofuel boom: the hike in crude oil prices, replacement of MTBE by ethanol as a gasoline additive in the US, and subsidies for ethanol and biodiesel in the US and EU. Using this historical simulation, we calibrate the key elasticities of energy substitution between biofuels and petroleum products in each region. With these parameter settings in place, the model does a reasonably good job of predicting the share of feedstock in biofuels and related sectors in accordance with the historical evidence between 2001 and 2006 in the three major biofuel producing regions: US, EU, and Brazil. The results from the historical simulation reveal an increased production of feedstock with the replacement of acreage under other agricultural crops. As expected, the trade balance in oil sector improves for all the oil exporting regions, but it deteriorates at the aggregate for the agricultural sectors.
