Abstract:

Genetic conservation is key to maintaining forests for the future; however, these face several threats. Mexico is an example of the degradation of forest genetic resources during the past three decades due to its deforestation rates. This country is considered a center of pine diversity but its genetic conservation efforts are not enough. To define genetic conservation units (GCUs) and propose measures for the conservation and sustainable use of 18 Mexican pine species, we analyzed the distribution of the species at the national level and in germplasm transfer zones, and evaluated the species with a set of minimum requirements for conservation and indicators from the EUFORGEN program. We determined that 13 to 15 genetic zones harbored the target species, in which Pinus teocote, Pinus cembroides, Pinus devoniana, Pinus maximinoi, Pinus douglasiana, and Pinus leiophylla were the most widely distributed. We defined 173 areas for establishing GCUs for the total of the species studied; 50% of them were selected from areas with genetic information, 5% were selected from seed stands, and 45% from natural forests. We detected that most of the forest reproductive material used is collected from seed stands, and the use of seeds from breeding trials is scarce.

Abstract:

Bamboos represent an emerging forest resource of economic significance and provide an avenue for sustainable development of forest resources. The development of the commercial bamboo industry is founded upon efficient molecular and technical approaches for the selection and rapid multiplication of elite germplasm for its subsequent propagation via commercial agro-forestry business enterprises. This review will delve into the micropropagation of Dendrocalamus asper, one of the most widely cultivated commercial varieties of bamboo, and will encompass the selection of germplasm, establishment of explants in vitro and micropropagation techniques. The currently available information pertaining to molecular biology, DNA barcoding and breeding, has been included, and potential areas for future research in the area of genetic engineering and gene regulation have been highlighted. This information will be of relevance to both commercial breeders and molecular biologists who have an interest in establishing bamboo as a crop of the future.

Abstract:

The introduction of mal-adapted genotype is a major concern in conservation and management of forest genetic resources. This is risky because it potentially threatens the integrity of the natural genetic structure of populations. Therefore, it is necessary to provide guidance on the choice of appropriate germplasm and determine how far it can be moved from its native environment. The most basic guidelines for germplasm movement involve the use of Regions of Provenance (RoP). The RoP for a forest species or sub-species is the area or group of areas subject to sufficiently uniform ecological conditions in which stands or seed sources showing similar phenotypic or genetic characters are found, taking into account altitudinal boundaries where appropriate. However, there is little information concerning Regions of Provenance and limited knowledge about safe limits to the movement of seed, cuttings and planting stock in Morocco. This paper establishes a conceptual framework based on Regions of Provenance that is designed to better understand, protect and use forest genetic resources in Morocco, especially the species for which no specific knowledge on local adaptation or no data about population differentiation are currently available. This is the ﬁrst study that represents a precise map of Regions of Provenance for Moroccan forest reproductive material and that provides detailed description on topographical, environmental and forest characteristics that characterize each Region of Provenance, by using geographical information system (GIS) techniques. A biogeography-based approach was applied and revealed that the territory was hierarchically organized into 2 Biogeographic Divisions, 9 Biogeographic Units and 19 Regions of Provenance. The RoP proposed are intended as a practical provenance decision-making tool to guide the movement of forest reproductive material in Morocco. This ensures the traceability of planting stock throughout the harvesting-seedling production-plantation process to a specified Forest Basic Material.

Abstract:

Canada is a large country with a great diversity of native plant material. Many of the native genera and species are related to crop plants. A review of different crop groupings revealed that over 30% of native plant material is related to crop species at the generic level. Fruit crops (111 species) and forage and turfgrass (138 species) crops had the highest number of related wild species. Nut crop species had relatively few native representatives (11 species) as did cereal, oilseed and other field crops (18 species). Special and minor acreage crops were represented by 86 species while landscape plants were represented by 137 genera. Forest trees are an important economic resource. Over 70 species of coniferous and deciduous trees are native to Canada. Many species, particularly in the fruit crop grouping, could be identified as world resources (e.g. Amelanchier) with the major part of their distribution occurring on Canadian soil. A concerted effort is needed to identify which species are endangered so that they can be preserved on a long-term basis. More research is needed to identify other long-term conservation goals coupled with crop development programs. Key words: Genetic conservation, Canada, wild plants, biodiversity

Abstract:

The river valley forests of the Irtysh River Basin are a germplasm bank of Salicaceae species and rare plant resources in China, and the distribution varies with the river and is highly distinctive. However, there is a dearth of systematic research on the characteristics of plant resources. In this study, a comprehensive investigation was conducted in the trunk stream and six tributaries with valley forest distribution in the Irtysh River Basin, and 244 quadrats were set up. The analysis focused on the composition of the flora and resource characteristics. The results reveal the following: (1) The valley forests of the Irtysh River Basin contain 256 species of plants belonging to 57 families and 178 genera, among which 19 species of trees, 23 species of shrubs, and 214 species of herbs were investigated. (2) Among the identified species, 226 (88.67%) were recognized as resource plants, with medicinal plants being the most abundant (176 species, 68.75% of the total). (3) The distribution patterns of trees, shrubs, and herbs of each resource type vary across rivers. Elevation drop, river length, and river distance all significantly affect the number of specie. This study elucidated the current status and distributional characteristics of plant resources in the valley forests of the Irtysh River Basin, which is essential for both biodiversity conservation and sustainable resource utilization.

Abstract:

SummaryThe Brazilian Amazon is a wide territory totalling 60 percent of the country's area. Of this area, 600 000 km2 is occupied by humans and related activities. This, among other factors, leads to the destruction of the Amazon's natural resources. The area of cut down and degraded forest may range from 5 to 12 percent of the total area. Therefore, many of the Amazon species are at risk of extinction. However, it is deemed urgent to investigate and preserve the threatened animal species.The total number of mammal species in the world is recorded at 4 629 and there is a great diversity of them in the Amazon, including animals that live on land, water or those that fly. Despite this huge biodiversity, the most relevant species for the human population, are the domestic species, brought to the continent by the first settlers: Portuguese and Spanish.The most important livestock in the Amazon region are cattle, horses, buffaloes, sheep and goats. They occupy all Amazon ecosystems and are of very important consideration for the opening of agricultural frontiers and for influencing the natural ecosystems, since the main reason for the cutting down of large forest areas has been to use them for pastures. This has resulted in an artificial ecosystem of degraded natural environment.The Animal Germplasm Bank of East Amazon (BAGAM) is the animal germplasm bank for the conservation of animal genetic resources of Embrapa East Amazon, and is part of the research project entitled “Animal Genetic Resources of East Amazon”. The project is formed by two sub-projects: “Germplasm bank of animals of interest to the East Region of the Brazilian Amazon” and “Genetic characterisation of buffaloes in the Brazilian Amazon, through the use of molecular markers”. These two sub-projects are linked to the research programme led by CENARGEN, called Conservation and Utilisation of Animal Genetic Resources.

Abstract:

Abstract In situ conservation is one of the methods recommended for conserving forest genetic resources. It aims to maintain and recover viable population of species in its natural habitat, to reintroduce the rare and endangered species and to recreate the habitats for plant species. Though mangrove rehabilitation programmes are widely carried out in Malaysia, the most common species planted for this purpose have always been Rhizophora apiculata (Bakau minyak) and Rhizophora mucronata (Bakau kurap). In this study, mangroves species namely Bruguiera cylindrica (Berus-berus), Ceriops tagal (Tengar), Xylocarpus granantum (Nyireh bunga), Xylocarpus moluccensis (Nyireh batu) and Sonneratia ovata (Gedabu) were planted in Bagan Datuk Mangrove Germplasm, Perak. These species were selected due to their unavailability in the study area. The main objective of this study is to rehabilitate and to introduce new species in the Bagan Datuk Mangrove Germplasm area. The initial growth and survival of saplings planted were measured and data obtained were analyzed using SPSS program. After 12 months of planting, the survival rate was 80% and Sonneratia ovata recorded the highest mean height increment.

Abstract:

The fruit harvest at physiological maturity of seeds is a globally accepted practice. This method has been traditionally practiced in horticultural crops where quality seeds and vigorous seedlings are ensured for cultivation of the species. The assessment of seed physiological maturity in the harvest of forest fruits and seeds are seldom practiced as seed physiological and biochemical studies in tropical seeds is little attempted. Since recalcitrant seed behavior among forest species is increasing, maintenance of seed viability and longevity ex situ becoming a challenging task in the forestry sector. Further, seed loss through fruit predation and pest infestation are other handicaps to these species. An improved technology for harvesting, storage and longevity of recalcitrant seeds will be a breakthrough for the germplasm conservation, management and utilization of forest genetic resources. Identification of biochemical factors at physiological maturity of seeds in conjunction with fruit morphological characters considered as optimum harvest practice for recalcitrant forest fruits and seeds. The practice could extend shelf life of recalcitrant seeds and bypass seed loss prior to the conventional harvest practices. This review outlines the research works carried out in seed physiological maturity of crops and its broad scope among recalcitrant forest seeds for long term germplasm storage.

Abstract:

The present study analyses the first data on genetic diversity of A. quebracho-blanco with the fragmentation of its natural habitat, supporting conservation strategies such as the definition of priority areas for conservation. DNA was extracted from 25 individuals of five populations of A. quebracho-blanco from Argentina, Paraguay, and Brazil. Six ISSR primers were used to characterize the genetic diversity and structure of this species. The genotypes were grouped according to a distance matrix, considering the genetic diversity indices of Nei (He), Shannon (H’), polymorphic information content (PIC), and heterozygosis (H). The populations showed an average genetic diversity that ranged from 0.09 to 0.15 for the Shannon index and from 0.19 to 0.31 for the Nei index; the Mantel test was not significant (r2 = 0.25, P = 0.106). The results obteined for the sampled populations reveal that conservation units are indispensable for conserving the species genetic resources. In addition, it would be essential to construct a germplasm bank for the Cordoba (Argentina) population, which is a population with high genetic diversity in a region of lower fragmentation compared to other regions evaluated, to ensure the conservation of A. quebracho-blanco.

Abstract:

Coming together to save the Earth. Ten years have passed since the Earth Summit in Rio created such passion and expectations. Whether the Convention on Biological Diversity has met those expectations or not vary from person to person.
Evidently, the Convention on Biological Diversity is complex, not only in its language, but also in its attempt to balance between conservation and sustainable use, and between the providers of and benefiters from biological diversity.
Subsequent to its conclusion, the Parties have strived to achieve these objectives. This thesis attempts to assist in this process by exploring the means of implementing the Convention on Biological Diversity and their consequences.
The scope of the thesis is limited to the matters of sovereignty rights and access to genetic resources, in an effort to clear up the uncertainties in the applications of these components. This thesis attempts to contribute a pragmatic perspective to these matters, which, at their core, rely on the crossing points in the implementation of the Convention on Biological Diversity and the Agreement on Trade-Related Aspects of Intellectual Property Rights. This thesis focuses on ways to reconcile property rights in genetic resources with patent rights in invention using genetic resources. It proposes one interpretation of property rights in genetic resources so as to avoid any conflict with patent rights and accordingly, avoid conflict between the requirements of the Convention on Biological Diversity and those of the Agreement on Trade-Related Aspects of Intellectual Property Rights.
I hope that the views and proposals expressed in this thesis will be considered along with other diverse approaches to the implementation of the Convention on Biological Diversity.

Abstract:

Abstract Forest fires are a universal problem that destroy a large amount of natural resources and creates environmental pollution. Forest firefighting is one of today’s most important events for natural and environmental resources protection and conservation. Unmanned aerial vehicle (UAV) with remote sensing system can offer a rapid, safe and low-cost approach for effective forest fire detection which have attracted researchers attention worldwide. In this paper, automatic detection of fire regions using both visual and infrared images is investigated. In order to improve the computational performance to satisfy the requirement of real-time processing, a reduced complexity fusion method is adopted in this research. Through testing the proposed approach on real video sequences, good detection performance is achieved and it is indicated that using multi-modal camera system to detect forest fire with application to firefighting UAV is very promising.

Abstract:

Tree species are characterized by their perennial growth habit, woody morphology, long juvenile period phase, mostly outcrossing behaviour, highly heterozygosity genetic makeup, and relatively high genetic diversity. The economically important trees have been an integral part of the human life system due to their provision of timber, fruit, fodder, and medicinal and/or health benefits. Despite its widespread application in agriculture, industrial and medicinal values, the molecular aspects of key economic traits of many tree species remain largely unexplored. Over the past two decades, research on forest tree genomics has generally lagged behind that of other agronomic crops. Genomic research on trees is motivated by the need to support genetic improvement programmes mostly for food trees and timber, and develop diagnostic tools to assist in recommendation for optimum conservation, restoration and management of natural populations. Research on long-lived woody perennials is extending our molecular knowledge and understanding of complex life histories and adaptations to the environment, enriching a field that has traditionally drawn its biological inference from a few short-lived herbaceous species. These concerns have fostered research aimed at deciphering the genomic basis of complex traits that are related to the adaptive value of trees. This review summarizes the highlights of tree genomics and offers some priorities for accelerating progress in the next decade.

Full text

Abstract:

This study challenges the current design of forest resource use contracts in Latin America. Radical rethinking of forest resource contracts is imperative, due to the constraints that now face the successful achievement of forest policy objectives of economic development and conservation of forest resources. The constraints identified in this study include: 1) financial incentives that favor selective logging rather than management in tropical forests; 2) lack of a technical basis for silviculture in neo-tropical forests; 3) governments that lack the administrative capacity and political will to impose management; 4) cultural and social norms that fail to recognize local users of forest resources. This study is intended to serve as a turning point in forest concession policy and provide useful guidelines for policy analysts, non-governmental organizations, and multilateral lending institutions interested in facilitating this process. A comprehensive rethinking of forest resource contracts will greatly benefit all those relying on the economic development and conservation of forests in Latin America.

Rights and Resources Initiative, June 2018. http://dx.doi.org/10.53892/exqc6889.

Full text

Abstract:

Faced with growing environmental threats, governments and the international community have sought ways to halt biodiversity loss and ecosystem degradation and realize global climate and development priorities. Today, expanding the global network of protected areas is a key approach for achieving the goals of the Convention on Biological Diversity (CBD), the 2030 Agenda for Sustainable Development, and the Paris Agreement on climate change. But human pressure is increasing in and around protected areas, and far from improving the lives of those affected by the growing number of conservation initiatives, land and forest sequestration through “fortress” conservation approaches is creating chronic patterns of abuse and human-rights violations. In a context where many protected areas are underfunded and therefore limited in their capacity to deliver climate or biodiversity outcomes, the push for still more and even larger parks and conservation areas only stands to exacerbate the existing funding gap and the potential for injustice. Yet, despite widespread poverty and insecure resource rights, evidence shows that Indigenous Peoples and local communities are nevertheless spending their limited resources on conservation efforts and achieving outcomes that are at least equivalent to those of government-funded protected areas. As this brief shows, there is an urgent need to replace the fortress-conservation model with rights-based approaches to both improve conservation outcomes and end human-rights abuses committed in the name of conservation.

Full text

Abstract:

Genetic resistance is often the least expensive, most effective, and ecologically-sound method of disease control. It is becoming apparent that plant genomes contain large numbers of disease resistance genes. However, the numbers of different resistance specificities within a genepool and the genetic mechanisms generating diversity are poorly understood. Our objectives were to characterize diversity in clusters of resistance genes in wild progenitors of cultivated lettuce in Israel and California in comparison to diversity within cultivated lettuce, and to determine the extent of gene flow, recombination, and genetic instability in generating variation within clusters of resistance genes. Genetic diversity of resistance genes was analyzed in wild and cultivated germplasm using molecular markers derived from lettuce resistance gene sequences of the NBS-LRR type that mapped to the major cluster if resistance genes in lettuce (Sicard et al. 1999). Three molecular markers, one microsatellite marker and two SCAR markers that amplified LRR- encoding regions, were developed from sequences of resistance gene homologs at the Dm3 cluster (RGC2s) in lettuce. Variation for these markers was assessed in germplasm including 74 genotypes of cultivated lettuce, L. saliva and 71 accessions of the three wild Lactuca spp., L. serriola, L. saligna and L. virosa that represent the major species in the sexually accessible genepool for lettuce. Diversity was also studied within and between natural populations of L. serriola from Israel and California. Large numbers of haplotypes were detected indicating the presence of numerous resistance genes in wild species. We documented a variety of genetic events occurring at clusters of resistance genes for the second objective (Sicard et al., 1999; Woo el al., in prep; Kuang et al., in prepb). The diversity of resistance genes in haplotypes provided evidence for gene duplication and unequal crossing over during the evolution of this cluster of resistance genes. Comparison of nine resistance genes in cv. Diana identified 22 gene conversion and five intergenic recombinations. We cloned and sequenced a 700 bp region from the middle of RGC2 genes from six genotypes, two each from L. saliva, L. serriola, and L. saligna . We have identified over 60 unique RGC2 sequences. Phylogenetic analysis surprisingly demonstrated much greater similarity between than within genotypes. This led to the realization that resistance genes are evolving much slower than had previously been assumed and to a new model as to how resistance genes are evolving (Michelmore and Meyers, 1998). The genetic structure of L. serriola was studied using 319 AFLP markers (Kuang et al., in prepa). Forty-one populations from Turkey, Armenia, Israel, and California as well as seven European countries were examined. AFLP marker data showed that the Turkish and Armenian populations were the most polymorphic populations and the European populations were the least. The Davis, CA population, a recent post-Columbian colonization, showed medium genetic diversity and was genetically close to the Turkish populations. Our results suggest that Turkey - Armenia may be the center of origin and diversity of L. serriola and may therefore have the greatest diversity of resistance genes. Our characterization of the diversity of resistance genes and the genetic mechanisms generating it will allow informed exploration, in situ and ex situ conservation, and utilization of germplasm resources for disease control. The results of this project provide the basis for our future research work, which will lead to a detailed understanding of the evolution of resistance genes in plants.

Washington, D.C: Natural Resources Conservation Service, January 2022. http://dx.doi.org/10.32747/2022.8135353.nrcs.

Full text

Abstract:

Throughout the eastern deciduous forests of North America, a lack of disturbance coupled with advancing ecological succession in many regions has led to forests dominated by even-aged sawtimber with very little in the early successional stage. Monitoring of response of these target species to early successional communities created through Working Lands for Wildlife and Regional Conservation Partnership Programs have been completed. ARU-based regional monitoring protocol was used to assess whip-poor-will occupancy across various landscapes contexts, silvicultural treatments, and forest types in the Appalachian Mountain and New England regions. Researchers conducted milkweed, monarch egg, and larvae surveys simultaneously with the pollinator surveys. Preliminary results support that increasing milkweed and nectar-rich plants within alder and upland early successional communities will provide valuable resources for the monarchs and other pollinators in the northern Great Lakes.--

Silverman, Allison. Using International Law to Advance Women’s Tenure Rights in REDD+. Rights and Resources Initiative, June 2015. http://dx.doi.org/10.53892/uyna2326.

Full text

Abstract:

Reducing Emissions from Deforestation and Forest Degradation (REDD+) is an international initiative to mitigate climate change in the forest sector. It is intended to incentivize developing countries to reduce greenhouse gas emissions from deforestation and forest degradation, as well as promote sustainable management of forests, and conservation and enhancement of forest carbon stocks. REDD+ has significant implications for land and resource rights, and raises particular concerns for women. These concerns arise from discrimination that women already face in resource management processes, largely due to unclear, unsecure and unequal tenure rights. Women represent a large percentage of the world’s poor, and they are often directly dependent on natural resources. As a result, there are significant risks that REDD+ could exacerbate existing inequalities for women if it fails to respect women’s tenure rights. This paper makes a case for advancing women’s tenure rights and how international law can be used to promote those rights in the context of REDD+.

Full text

Abstract:

Several countries have implemented payment-for-ecosystem-services (PES) programs, buoyed by the promise of these programs as a win-win strategy that would allow both the conservation of natural resources, and the reduction of poverty for rural households and communities. Our study evaluates the effect on deforestation of Costa Rica's PES program, one of the oldest country-wide programs in the world. Costa Rica approved the 1996 Forest Law (Law No. 7575), creating a PES program that compensates landowners for forest conservation. We estimate these effects using an event study design with staggered entry into treatment. Our results show a statistically significant effect for the first year with a decrease in deforestation of 0.21 ha, but not for the following years. Given that the baseline level of deforestation in our sample is low, the magnitude of the effect is large. When compared to the pre-2016 average level of within farm deforestation, our estimated effect would imply a 100% reduction in deforestation for the first year after enrollment. Given the program pays the participants for a 5-year period, and that the effect is significant only during the first year, it may be beneficial for the program to reduce its length and implement required simplified annual contract renewals or other behavioral interventions to reduce noncompliance in subsequent years.

Full text

Abstract:

Record-breaking global temperatures and increasing frequency and intensity of extreme weather events underline the threat posed by the climate crisis. The Amazonia rainforest is widely regarded as one of several key bulwarks against global warming and a transition to a low-carbon future. Yet the worlds largest tropical forest is experiencing intense ecological degradation due to intensive cattle ranching, large-scale farming, unstainable mining, and a constellation of illegal activities. A paradigm shift is required in the economic model for the Amazonia and the people who live there. Put simply, it is critical that a higher value is attached to preserving a standing forest than one that is cleared. Bioeconomy offers a viable alternative precisely because of how it incentivizes ecological conservation while simultaneously generating economic opportunities based on the sustainable management of diverse natural resources. There is no unified or shared definition of bioeconomy in the Amazonia. In North America and Western Europe, most definitions tend to emphasize economic growth and market competition with a particular focus on biotechnology to reconcile economic growth with environmental sustainability. Given that most resources available to support the development of the bioeconomy are aligned with interpretations from the Global North,“semantic asymmetries” between funders and countries and entrepreneurs in the Global South could impede access to vital investment, funding and support. Indeed, definitions exported from upper-income settings may not be fully commensurate or appropriate to regions such as the Amazonia, home to over 40 million residents. Amazonias immense biodiversity and the presence of over 400 separate indigenous and other traditional communities, many of whom depend on its resources for livelihoods and subsistence, underline the imperative of localized approaches to understanding bioeconomy and capitalizing on its potential.
