Abstract:

Uttarakhand state is well known for its biodiversity, especially for its animal diversity. The great animal diversity includes about 102 classes of mammals, 69 classes of cold-blooded animals and 19 classes of cold blooded vertebrates. The unique animal diversity of the state attracts tourists from all across the world at large number. In order to protect the animal diversity, wildlife management department of government of Uttarakhand made many strategies and policies. Human activities and loss of habitat, desertification and deforestation and wildlife trade and climate change are the major barriers to the animal diversity in the Uttarakhand state. This paper discussed an overview of animal diversity status in Uttarakhand, focused on biodiversity in Uttarakhand, threats to biodiversity, wildlife management and faunal diversity in Uttarakhand state. Climate change is the major issue in front of the animal diversity. In this regard, it is necessary to take responsibility by everyone to protect the nature that will protect the biodiversity of the state as well as of the world and also help to understand that in future animal diversity the major part of the world.

Abstract:

Secondary metabolites are often considered within the remit of bacterial or plant research, but animals also contain a plethora of these molecules with important functional roles. Classical feeding studies demonstrate that, whereas some are derived from diet, many of these compounds are made within the animals. In the past 15 years, the genetic and biochemical origin of several animal natural products has been traced to partnerships with symbiotic bacteria. More recently, a number of animal genome-encoded pathways to microbe-like natural products have come to light. These pathways are sometimes horizontally acquired from bacteria, but more commonly they unveil a new and diverse animal biochemistry. In this review, we highlight recent examples of characterized animal biosynthetic enzymes that reveal an unanticipated breadth and intricacy in animal secondary metabolism. The results so far suggest that there may be an immense diversity of animal small molecules and biosynthetic enzymes awaiting discovery. This biosynthetic dark matter is just beginning to be understood, providing a relatively untapped frontier for discovery.

Abstract:

Coral reefs host hundreds of thousands of animal species that are increasingly threatened by anthropogenic disturbances. These animals host microbial communities at their surface, playing crucial roles for their fitness. However, the diversity of such microbiomes is mostly described in a few coral species and still poorly defined in other invertebrates and vertebrates. Given the diversity of animal microbiomes, and the diversity of host species inhabiting coral reefs, the contribution of such microbiomes to the total microbial diversity of coral reefs could be important, yet potentially vulnerable to the loss of animal species. Analysis of the surface microbiome from 74 taxa, including teleost fishes, hard and soft corals, crustaceans, echinoderms, bivalves and sponges, revealed that more than 90% of their prokaryotic phylogenetic richness was specific and not recovered in surrounding plankton. Estimate of the total richness associated with coral reef animal surface microbiomes reached up to 2.5% of current estimates of Earth prokaryotic diversity. Therefore, coral reef animal surfaces should be recognized as a hotspot of marine microbial diversity. Loss of the most vulnerable reef animals expected under present-day scenarios of reef degradation would induce an erosion of 28% of the prokaryotic richness, with unknown consequences on coral reef ecosystem functioning.

Abstract:

Accredited zoos and aquariums continually strive to ensure high levels of animal welfare for the animals under their professional care. Best management practices include conducting research to better understand factors that lead to optimal welfare and then turning findings into practice. The current study is part of the larger Cetacean Welfare Study or more formally, “Towards understanding the welfare of cetaceans in zoos and aquariums.” Facilities participating in the study were accredited by the Alliance of Marine Mammal Parks and Aquariums and/or the Association of Zoos and Aquariums. Animal management factors and habitat characteristics were examined in relation to two potential indicators of welfare for common (Tursiops truncatus) and Indo-Pacific (Tursiops aduncus) bottlenose dolphins. Specifically, we examined environmental enrichment, animal training, and habitat characteristics that were significantly related to behavioral diversity and route tracing, a form of stereotypic behavior. Behavior was recorded from 47 animals at 25 facilities around the world. Overall, the rate of route tracing behavior observed during the study was very low and few animal management factors or habitat characteristics were found to be related to this behavior. One factor, enrichment diversity, had a significant positive relationship with route tracing and an inverse relationship with behavioral diversity. This finding may be a product of a response mounted by animal care specialists to the behavior as opposed to a cause. Animals that engaged in this behavior were likely provided more diverse enrichment in attempts to ameliorate the stereotypic behavior. However, multiple factors were found to significantly relate to behavioral diversity, a potential positive indicator of welfare for bottlenose dolphins. Dolphins that were trained on a predictable schedule had higher behavioral diversity than those on a semi-predictable schedule. There was a positive significant relationship between behavioral diversity and the number of habitats to which an animal had access, and a significant inverse relationship with the maximum depth of the habitat. Finally, animals that were split into groups and reunited or rotated between subgroups had higher behavioral diversity than animals managed in the same group. Information gained from the current study suggested that animal management techniques may be more important in ensuring good welfare for bottlenose dolphins than focusing on habitat size.

Abstract:

Farming and agriculture are vital to our survival and we have domesticated around 35 species of animals, many of which are farmed for food. Cows, sheep, chickens, pigs, goats and horses have been some of the animals whose domestication has played a key role in advancing human civilisation through added food security and these have been selectively bred over thousands of years to develop a variety of breeds, each of which offer particular characteristics to suit certain needs or local conditions. However, globalisation and standardisation have led to the loss of many of these diverse breeds, with many farmers now raising hybrids to meet the demands of large multinational commercial entities.

Abstract:

Diffraction gratings were believed to be a rare cause of colour in nature. However, surface gratings, which include diffraction gratings and Bragg gratings, appear to occur in many forms within a diversity of animals. Structural colours in general have implications in the study of animal behaviour and evolution.

Abstract:

BACKGROUND:Clostridium difficile is an important cause of intestinal infections in some animal species and animals might be a reservoir for community associated human infections. Here we describe a collection of animal associated C. difficile strains from 12 countries based on inclusion criteria of one strain (PCR ribotype) per animal species per laboratory.RESULTS:Altogether 112 isolates were collected and distributed into 38 PCR ribotypes with agarose based approach and 50 PCR ribotypes with sequencer based approach. Four PCR ribotypes were most prevalent in terms of number of isolates as well as in terms of number of different host species: 078 (14.3% of isolates
4 hosts), 014/020 (11.6%
8 hosts)
002 (5.4%
4 hosts) and 012 (5.4%
5 hosts). Two animal hosts were best represented
cattle with 31 isolates (20 PCR ribotypes
7 countries) and pigs with 31 isolates (16 PCR ribotypes
10 countries).CONCLUSIONS:This results show that although PCR ribotype 078 is often reported as the major animal C. difficile type, especially in pigs, the variability of strains in pigs and other animal hosts is substantial. Most common human PCR ribotypes (014/020 and 002) are also among most prevalent animal associated C. difficile strains worldwide. The widespread dissemination of toxigenic C. difficile and the considerable overlap in strain distribution between species furthers concerns about interspecies, including zoonotic, transmission of this critically important pathogen.

Abstract:

The hypothesis that midge sex pheromones could be chemically more diverse in structure than previously thought was tested in the context of four midge species of importance to UK horticulture: pear leaf midge, Dasineura pyri; pear midge, Contarinia pyrivora; blackcurrant midge, D. tetensi; and blackberry midge, D. plicatrix. The major component of the pheromone of D. pyri was identified as (2R, 13R, 8Z)-2, 13-diacetoxy-8-heptadecene. Four isomers were separated by HPLC and in field tests the first eluting isomer only was attractive to male midges. Analysis of volatile collections from female C. pyrivora showed two consistent responses from male midges and they were identified as 2,7-diacetoxyundecane and 7-acetoxyundecane-2-one. The field testing with isomers of 2,7-diacetoxyundecane separated by HPLC revealed that the first and the third eluting isomers were attractive. The racemic 7-acetoxyundecane-2-one was active as well as the first eluting isomer from HPLC. Two EAG active components were detected in D. tetensi female volatile collections. The major component was identified as (Z)-2,12-diacetoxy-8-heptadecene and after separation of stereoisomers by HPLC the third eluting isomer has shown to be attractive to male D. tetensi in the field. The structure for the minor component was proposed as a keto-acetate homologue of the corresponding major component. Preliminary work carried out on identification of the female sex pheromone of D. plicatrix indicated two responses from conspecific males. These were shown to be 15-carbon acetates with the acetate function at C-2, probably with two and one double bonds respectively.

Abstract:

The dromedary camel (Camelus dromedarius) commonly referred to as ‘ship of the desert’ has played an important part in the development and expansion of trading networks across inhospitable habitats over 3000 years, linking Arabian, Asian, African and European civilisations. Caravan roads, which are part of the major trading networks, have facilitated livestock exchange across large geographic distances. Dromedary camels are known to have been extensively used as pack animals along these caravan roads. Archaeological records point towards the southern Arabian Peninsula as the origin of the domestic dromedary camels. However, there is uncertainty about the dromedary’s dispersal out of the Arabian Peninsula to Africa and other parts of Asia. In contrast to other livestock species, the domestication of the dromedary camel has not been investigated using genetic evidence. Also, there is no information available on the genetic relationship between dromedary populations across their entire geographic distribution. Previous genetic studies were limited to a restricted number of animals, often from a single population or a small geographic region within countries. The general aims of this thesis were to characterise the origin and the geographic distribution of genetic diversity in dromedary camels and to understand the demographic history across the species range. To ascertain the global genetic structure and to contribute to the knowledge on the spread of the species after domestication, we sampled 1,083 modern-day dromedary camels from 21 countries representing the species range. Mitochondrial DNA and microsatellite markers were used for these analyses. Nine hundred and seventy animals were investigated using 17 autosomal microsatellite loci, and 759 animals were studied at the mitochondrial DNA level using a continuous 867 bp fragment spanning the end of cytochrome b, the tRNAs threonine and proline, and the beginning of the control region.

Abstract:

Although viruses are ubiquitous, infecting all biological entities including viruses themselves, we know relatively little of viral diversity beyond those implicated in diseases affecting humans and domestic plants and animals. Recent advances in metagenomic sequencing technologies, particularly bulk RNA shotgun sequencing ('meta-transcriptomics'), have enabled a dramatic increase in our understanding of virus diversity and evolution. However, although likely central to disease emergence, the total viral diversity (i.e. virome) of many vertebrates and their eukaryotic parasites remain uncharacterised. In this thesis I use meta-transcriptomic based virus discovery to characterise both the viromes of species threatened by anthropocentric activities and their parasitic invertebrates. In total, I describe the discovery of 102 novel viruses in samples collected from four vertebrate species - eastern Australian Humpback whales, koalas and three species of Antarctic penguin. These viruses were often highly diverse from those previously characterised, providing a broadened perspective on virome diversity in these animals. In addition, due to their role as vectors of disease in humans and wildlife, ticks and fleas were collected during population studies of two species of eastern Australian Bandicoot as well as from Antarctic penguin nesting sites. Meta-transcriptomic analyses of these parasites identified 46 novel viruses, often highly divergent from those viruses previously characterised. Australia and Antarctica have unique fauna that have evolved in isolation for millions of years. It may therefore be assumed that the viruses infecting these species would be equally as divergent. Both Australian and Antarctic tick viruses clustered phylogenetically with other tick-associated viruses, suggesting that they co-evolved with their tick hosts as they have diversified.

Abstract:

The interactions between host and gut microbiota are a rapidly developing field with a plethora of implications. Recent developments in identification and quantification methods of gut microbes allow for a better understanding of said interactions. For the local broiler production industry, studying the microbiome of the gastrointestinal tract (GIT) is imperative to ensure ease of transitioning into an antibiotic-free feeding practice. Clostridium perfringens infections are a major burden for the global poultry industry and can lead to necrotic enteritis (NE). The economic losses induced by NE in the South African broiler industry are estimated to be $68.81 million per annum. In this trial, day-old Ross 308 broiler males were randomly placed in an environmentally controlled house and subjected to eight dietary treatments with 12 replicate pens each containing 23 birds. The antibiotic growth promoter (AGP), zinc bacitracin (ZB), was used as the positive control, and three additional feed additives were used either alone or in combination. The three feed additives are classified as a direct fed microbial (DFM), an essential oil mixture (EO), and finally a mixture of EOs and organic acids (OAs). To induce C. perfringens infection, birds received a coccidial vaccine (Immunocox, Ceva) of 10x the prescribed dosage at 10 days of age and were orally inoculated with a broth of C. perfringens at 14 days of age. Both ileal and caecal digesta samples were collected at 21 and 35 days of age. Bacterial 16S rRNA sequencing was performed on these samples using a customized chip containing 100 selected intestinal bacteria. Age had the most significant effect on microbial abundance in both the ileum and the caeca. The dominant bacterial phylum regardless of age was Firmicutes, followed by Bacteroidetes and Proteobacteria. The ileum samples showed that microbial diversity increased with age, whereas the caecal samples revealed a reduction in diversity in the older samples. For the 35-day samples, the DFM and EO treatments increased ileal Lactobacillus and Lachnospiraceae respectively when compared to the negative control (no additives). Increased Lactobacillus and Lachnospiraceae are beneficial for broiler health and production. No significant differences were observed between the positive control (AGP) and the other treatment groups except for the EO + AGP combination group. Further research on the microbiome of the chicken’s intestinal tract is necessary.

Abstract:

Opisthokonta is an eukaryotic supergroup that contains Metazoa, Fungi and their unicellular relatives. Therefore, this group provides an ideal framework to study distinct unicellular-multicellular transitions, among them, the transition towards animal multicellularity. This thesis aims to describe new Opisthokonta diversity at many different levels, a very neeeded starting point to better understand the evolution of opisthokonts and the origin of multicellularity in animals. In particular, we here described a new genus and species at the onset of Holomycota (Parvularia atlantis), detected new molecular metazoan diversity through a metabarcoding approach, and evaluated the power of single-cell genomics to increment the genomic diversity of choanoflagellates. Overall, this thesis provided new insights into the diversity of Opisthokonta and into the power of single-cell genomics technologies. Finally, our results also have reshaped the phylogeny of choanoflagellates and increased the knowledge of the pre-metazoan genetic tool-kit.
Els Opistoconts són el supergroup d'eucariotes que engloba els animals, els fongs i els seus respectius parents unicel·lulars. Ofereixen, per tant, un marc ideal on estudiar la transició d'organismes unicel·lulars a pluricel·lulars, entre elles, la transició a la pluricel·lularitat animal. Aquesta tesis pretén entendre millor la diversitat dels Opistoconts a diferents nivells, com a primer pas imprescindible, per poder entendre millor la seva evolució i obtenir noves dades que ajudin a compendre els processos que van precedir l'origen de la pluricel·lularitat animal. Concretament, els resultats obtinguts corresponen a: la descripció d'un nou génere i una nova espècie a la base dels holomycots (Parvularia atlantis), la detecció de nova diversitat animal gràcies a un estudi metagenètic (metabarcoding) i l'avaluació de l'ús de técniques de genòmica unicel·lular (Single-cell genomics) per poder expandir la diversitat genòmica dels coanoflagel·lats. Amb tot, els resultats donen una millor comprensió de la diversitat dels Opistoconts i del potencial de la genòmica unicel·lular. Finalment, els resultats han permés també remodelar la filogènia dels coanoflagel·lats i incrementar el conexiement sobre el contingut genètic que va precedir l'aparició dels animals.

Abstract:

The article describes some of animal external characteristics and yield indicators. The mentioned animals are important for the country's agro-biodiversity, having valuable genes and their alleles, the loss of which will significantly limit the possibilities and efficiency of providing breeding works. Also Georgia is a country of great diversity of freshwater fish species that is facilitated due to the landscape diversity and richness of water resources. In addition, local breed varieties and populations are valuable because they are considered as the best adapted to local conditions and resistant to various diseases. Unfortunately, today their number is significantly reduced, their genetic purity is also in question. We consider the use of in- situ, ex- situ, in vivo, in vitro conservation methods to be the best way out of the situation.

Abstract:

Ornamental shrubs are one of the elements of the formation of the park environment and an integral part of urban landscaping. The paper presents the results of studying the species diversity of shrubs in park plantations in the city of Voronezh. The range includes more than 30 species, decorative forms and varieties of plants. Deciduous species are predominant, while coniferous species account for not much more than 10 %. Deciduous shrubs growing in the parks of the city of Voronezh belong to 14 families. Among them, there are beautiful flowering and decorative deciduous species, as well as plants with attractive fruits. Coniferous species belong to two families-pine and cypress. The cypress family is characterized by the greatest species (form, variety) diversity. The most popular types and varieties of coniferous trees are Western thuja "Smaragd", Western thuja "Danika", Cossack juniper, Cossack juniper"Tamariscifolia". The main types of shrub plantings in park stands are hedges and row plantings. The most common hedges are made of brilliant dogwood and Wanguttaspirea. Less often, groups and tapeworms are used in park plantings. The analysis of the geographical origin of shrubs showed that the largest number of species are introduced − their participation is more than 90%, the share of local species is less than 10%.

Abstract:

At present, the biological diversity of tree species is drying up. One of the main reasons for extinction is the destructive anthropogenic impact. According to the latest data, it became known that the Karelian birch was included in the Red Book of the Republic of Karelia as an endangered and diminishing species. The in vitro clonal micropropagation technology can help to quickly restore the population of Karelian birch. And also the technology under consideration will help to massively produce seedlings and seedlings of Karelian birch for both decorative and silvicultural purposes.

Abstract:

Today, the question of the need for environmental education is of particular importance. It is necessary to restore harmonious ties between man and nature, and this is possible only in contact with the natural environment itself. The irrational use of natural resources, the progressing economic activity of man, which does not take into account the laws of the development of natural systems, lead to a change in natural processes, a violation of the balance of the biosphere. Analysis of various approaches to educational activities in the field of environmental culture revealed the importance of specially protected natural areas in environmental education. They have unique benefits for biodiversity education by providing visual illustrations of the diversity of natural ecosystems.

Abstract:

This article presents aspects of decoration of wood-shrub arboretum species of VSUFT. The relative limitations of floristic composition in parks and squares indicate the need for enrichment by representatives of the Rosaceae Juss family. The task of the study was to select species that are more decorative and adaptable to the extreme conditions of the modern environment. It is possible to increase species diversity in various ways, including through landscaping. For this, various techniques and combinations of forms and paints of vegetation are used, since the enrichment and renewal of the assortment of decorative rocks is very important. Shrub-tree species of the Rosaceae Juss family. are the most promising breeds in Voronezh and the Voronezh region as a whole.

Abstract:

Many people enjoy wildlife. Nationwide, Americans spend over $144 billion annually on fishing, hunting, and wildlife-watching activities. However, wildlife is not always welcome in or near homes, buildings, or other property and can cause significant damage or health and safety issues. Many people who experience a wildlife conflict prefer to resolve the issue without harming the offending animal. Of the many options available (i.e., habitat modification, exclusion, repellents) for addressing nuisance wildlife problems, translocation—capturing and moving—of the offending animal is often perceived to be effective. However, trapping and translocating wild animals is rarely legal nor is it considered a viable solution by wildlife professionals for resolving most nuisance wildlife problems. Reasons to avoid translocating nuisance wildlife include legal restrictions, disease concerns, liability issues associated with injuries or damage caused by a translocated animal, stress to the animal, homing behavior, and risk of death to the animal. Translocation is appropriate in some situations such as re-establishing endangered species, enhancing genetic diversity, and stocking species in formerly occupied habitats. The main focus of this publication, however, is to address nuisance wildlife issues that may be commonly encountered by homeowners and nuisance wildlife control professionals.

National Park Service, April 2021. http://dx.doi.org/10.36967/nrr-2284622.

Full text

Abstract:

The Heartland Inventory and Monitoring Network (HTLN) is a component of the National Park Service’s (NPS) strategy to improve park management through greater reliance on scientific information. The purposes of this program are to design and implement long-term ecological monitoring and provide information for park managers to evaluate the integrity of park ecosystems and better understand ecosystem processes. Concerns over declining surface water quality have led to the development of various monitoring approaches to assess stream water quality. Freshwater streams in network parks are threatened by numerous stressors, most of which originate outside park boundaries. Stream condition and ecosystem health are dependent on processes occurring in the entire watershed as well as riparian and floodplain areas; therefore, they cannot be manipulated independently of this interrelationship. Land use activities—such as timber management, landfills, grazing, confined animal feeding operations, urbanization, stream channelization, removal of riparian vegetation and gravel, and mineral and metals mining—threaten stream quality. Accordingly, the framework for this aquatic monitoring is directed towards maintaining the ecological integrity of the streams in those parks. Invertebrates are an important tool for understanding and detecting changes in ecosystem integrity, and they can be used to reflect cumulative impacts that cannot otherwise be detected through traditional water quality monitoring. The broad diversity of invertebrate species occurring in aquatic systems similarly demonstrates a broad range of responses to different environmental stressors. Benthic invertebrates are sensitive to the wide variety of impacts that influence Ozark streams. Benthic invertebrate community structure can be quantified to reflect stream integrity in several ways, including the absence of pollution sensitive taxa, dominance by a particular taxon combined with low overall taxa richness, or appreciable shifts in community composition relative to reference condition. Furthermore, changes in the diversity and community structure of benthic invertebrates are relatively simple to communicate to resource managers and the public. To assess the natural and anthropo-genic processes influencing invertebrate communities, this protocol has been designed to incorporate the spatial relationship of benthic invertebrates with their local habitat including substrate size and embeddedness, and water quality parameters (temperature, dissolved oxygen, pH, specific conductance, and turbidity). Rigid quality control and quality assurance are used to ensure maximum data integrity. Detailed standard operating procedures (SOPs) and supporting information are associated with this protocol.

Einarsson, Rasmus. Nitrogen in the food system. TABLE, February 2024. http://dx.doi.org/10.56661/2fa45626.

Full text

Abstract:

Nitrogen (N) plays a dual role in the agri-food system: it is an essential nutrient for all life forms, yet also an environmental pollutant causing a range of environmental and human health impacts. As the plant nutrient needed in greatest quantities, and as a building block of proteins and other biomolecules, N is a necessary part of all life. In the last century, an enormous increase of N turnover in the agri-food system has enabled increasing per-capita food supply for a growing world population, but as an unintended side effect, N pollution has increased to levels widely agreed in science and policy to be far beyond sustainable limits. There is no such thing as perfectly circular N supply. Losses of N to the environment inevitably arise as N is transformed and used in the food system, for example in soil processes, in manure storage, and in fertilizer application. This lost N must be replaced by ‘new’ N, which is N converted to bioavailable forms from the vast atmospheric pool of unreactive dinitrogen (N2). New N comes mainly as synthetic N fertilizer and through a process known as biological N fixation (BNF). In addition, there is a large internal flow of recycled N in the food system, mainly in the form of livestock excreta. This recirculated N, however, is internal to the food system and cannot make up for the inevitable losses of N. The introduction of synthetic N fertilizer during the 20th century revolutionized the entire food system. The industrial production of synthetic N fertilizer was a revolution for agricultural systems because it removed the natural constraint of N scarcity. Given sufficient energy, synthetic N fertilizer can be produced in limitless quantities from atmospheric dinitrogen (N2). This has far-reaching consequences for the whole agri-food system. The annual input of synthetic N fertilizer today is more than twice the annual input of new N in pre-industrial agriculture. Since 1961, increased N input has enabled global output of both crop and livestock products to roughly triple. During the same time period, total food-system N emissions to the environment have also more than tripled. Livestock production is responsible for a large majority of agricultural N emissions. Livestock consume about three-quarters of global cropland N output and are thereby responsible for a similar share of cropland N emissions to air and water. In addition, N emissions from livestock housing and manure management systems contribute a substantial share of global N emissions to air. There is broad political agreement that global N emissions from agriculture should be reduced by about 50%. High-level policy targets of the EU and of the UN Convention on Biological Diversity are for a 50% reduction in N emissions. These targets are in line with a large body of research assessing what would be needed to stay within acceptable limits as regards ecosystem change and human health impacts. In the absence of dietary change towards less N-intensive diets, N emissions from food systems could be reduced by about 30%, compared to business-as-usual scenarios. This could be achieved by implementing a combination of technical measures, improved management practices, improved recycling of wasted N (including N from human excreta), and spatial optimization of agriculture. Human dietary change, especially in the most affluent countries, offers a huge potential for reducing N emissions from food systems. While many of the world’s poor would benefit nutritionally from increasing their consumption of nutrient-rich animal-source foods, many other people consume far more nutrients than is necessary and could reduce consumption of animal-source food by half without any nutritional issues. Research shows that global adoption of healthy but less N-polluting diets might plausibly cut future food-system N losses by 10–40% compared to business-as-usual scenarios. There is no single solution for solving the N challenge. Research shows that efficiency improvements and food waste reductions will almost certainly be insufficient to reach agreed environmental targets. To reach agreed targets, it seems necessary to also shift global average food consumption onto a trajectory with less animal-source food.

Full text

Abstract:

Our original objectives were to assess the unexplored dimension of alternative splicing as a source of genetic variation. In particular, we sought to initially establish an alternative splicing database for Arabidopsis, the only plant for which a near-complete genome has been assembled. Our goal was to then use the database, in part, to advance plant gene prediction programs that are currently a limiting factor in annotating genomic sequence data and thus will facilitate the exploitation of the ever increasing quantity of raw genomic data accumulating for plants. Additionally, the database was to be used to generate probes for establishing high-throughput alternative transcriptome analysis in the form of a splicing-specific oligonucleotide microarray. We achieved the first goal and established a database and web site termed Alternative Splicing In Plants (ASIP, http://www.plantgdb.org/ASIP/). We also thoroughly reviewed the extent of alternative splicing in plants (Arabidopsis and rice) and proposed mechanisms for transcript processing. We noted that the repertoire of plant alternative splicing differs from that encountered in animals. For example, intron retention turned out to be the major type. This surprising development was proven by direct RNA isolation techniques. We further analyzed EST databases available from many plants and developed a process to assess their alternative splicing rate. Our results show that the lager genome-sized plant species have enhanced rates of alternative splicing. We did advance gene prediction accuracy in plants by incorporating scoring for non-canonical introns. Our data and programs are now being used in the continuing annotation of plant genomes of agronomic importance, including corn, soybean, and tomato. Based on the gene annotation data developed in the early part of the project, it turned out that specific probes for different exons could not be scaled up to a large array because no uniform hybridization conditions could be found. Therefore, we modified our original objective to design and produce an oligonucleotide microarray for probing alternative splicing and realized that it may be reasonable to investigate the extent of alternative splicing using novel commercial whole genome arrays. This possibility was directly examined by establishing algorithms for the analysis of such arrays. The predictive value of the algorithms was then shown by isolation and verification of alternative splicing predictions from the published whole genome array databases. The BARD-funded work provides a significant advance in understanding the extent and possible roles of alternative splicing in plants as well as a foundation for advances in computational gene prediction.

Full text

Abstract:

With roots as far as the Bronze age, equines have played an invaluable role in history, both with regards to agriculture and forestry, warfare, transportation and leisure, and therefore hold important cultural significance in the Nordics. The link between horses and the welfare benefits of their caregivers makes the species an important part of society as well. Since the agricultural and industrial revolution, the equine sector has been influenced by a range of challenges due to the dramatic change in the role of horses in society, especially for the Nordic native breeds. However, as society adapts and finds new ways to use and protect them, there is a hope for the future. Although there has been cooperation between the Nordic countries in the horse sector, a collective report of the status of all the Nordic countries has been missing. This report marks a start for this type of effort by considering both commercial and native breeds. Further, it comprises the horse sector in the Nordics, with a special focus on the native horse breeds and the possibilities they carry for environmental sustainability, their socio-economic importance, their genetics as well as their risk status. The report further evaluates the Domestic Animal Diversity Information System (DAD-IS) maintained and developed by FAO as a tool for gathering information about the development and current status of the native breeds. The goal of this report is to identify knowledge gaps and areas of improvement for the Nordic equine sector and the collected data of the native horse breeds. One of the biggest challenges has been to find validated information sources for the population numbers of the breeds in each country – there are varying estimates for both commercial and native breeds. The numbers have significant impact for the determination of managing strategies of the populations. Reports for each of the countries (Denmark, Finland, the Faroe Islands, Iceland, Norway and Sweden) are presented, and depict the current role of horses, breeding, population development and economic values of the equine sector are listed in each of the country-reports. The information in the country reports were derived from a questionnaire and by using DAD-IS.

Full text

Abstract:

Expanding world hunger calls for increasing available food resources. Ruminants have the remarkable ability to convert human-indigestible plant biomass into human-digestible food products, due to a complex microbiome residing in the rumen compartment of their upper digestive tract. One way to tackle the problem of diminishing food resources is to increase the animals' energetic efficiency, i.e., the efficiency with which they convert energy from feed, thereby increasing food availability while lowering the environmental burden, as these animals would produce more and eat less. We hypothesize that the cow's feed efficiency is dependent on the taxonomic composition, coding capacity and activity of its reticulorumenmicrobiota. To test this hypothesis, three aims are defined: (1) Evaluation of the feed efficiency of 146 dairy cows and defining two groups representing the highest and lowest 25% using the Israeli group's unique facility; (2) Comparing these two groups for microbiota diversity, identity and coding capacity using next-generation sequencing and metagenomic approaches; (3) Comparing the reticulorumenmicrobiota metabolic activity parameters. We measured feed efficiency in 146 milking cows and analyzed the taxonomic composition, gene content, microbial activity and metabolomic composition of rumen microbiomes from the 78 most extreme animals. Lower richness of microbiome gene content and taxa was tightly linked to higher feed efficiency. Microbiome genes and species accurately predicted the animals' feed-efficiency phenotype. Specific enrichment of microbes and metabolic pathways in each of these microbiome groups resulted in increasing valuable metabolites and decreasing unusable ones such as methane in efficient animals. This ecological and mechanistic understanding of the rumen microbiome could lead to an increase in available food resources and environmentally friendly livestock agriculture.
