The rich diversity of morphology and behavior displayed across primate species provides an informative context in which to study the impact genomic on fundamental biological processes. Analysis that insight into long-standing questions evolutionary conservation biology is urgent given severe threats these are facing. Here, we present high-coverage whole-genome data from 233 representing 86% genera all 16 families. This dataset was used, together with fossil calibration, create a nuclear DNA...
Personalized genome sequencing has revealed millions of genetic differences between individuals, but our understanding their clinical relevance remains largely incomplete. To systematically decipher the effects human variants, we obtained whole-genome data for 809 individuals from 233 primate species and identified 4.3 million common protein-altering variants with orthologs in humans. We show that these can be inferred to have nondeleterious humans based on presence at high allele...
Abstract Noncoding DNA is central to our understanding of human gene regulation and complex diseases 1,2 , measuring the evolutionary sequence constraint can establish functional relevance putative regulatory elements in genome 3–9 . Identifying genomic that have become constrained specifically primates has been hampered by faster evolution noncoding compared protein-coding 10 relatively short timescales separating primate species 11 previously limited availability whole-genome sequences 12...
Background Understanding changes in the host-parasite relationship due to habitat fragmentation is necessary for better management and conservation of endangered species fragmented landscapes. Pathogens parasites can pose severe threat restricted environments such as forest fragments where there increased contact wildlife with human livestock populations. Environmental stress reduced nutritional level influence parasite infection intensity on native species. In this study, we examine impact...
Tiger (Panthera tigris), an endangered species, is under severe threat from poaching, habitat loss, prey depletion and disturbance. Such factors have been reported causing local extermination of tiger populations including in one the most important reserves India, namely Sariska Reserve (STR) northwestern India. Consequently, tigers were reintroduced STR between 2008 2010, but inadequate breeding success was observed over years, thus invoking investigation to ascertain physiological...
Livestock grazing in protected areas is considered a threat and detrimental to many wildlife species their habitats. In the current study, we examined impact of livestock on physiological stress response parasite prevalence Himalayan ibex population Spiti valley, Himalayas. We standardized cortisol enzyme immunoassay measure fecal glucocorticoid metabolites (fGCM) concentrations. A total 192 samples were collected from eight different locations ungrazed valley during 2015 2016. also examine...
Ungulates living in seasonal environments adopt complex life history strategies to cope with pronounced temporal and spatial variability environmental conditions resource availability. Understanding the reproductive of slow-breeding mountain ungulates associated stress, particularly context human- climate-induced changes, is crucial devising effective long-term management conservation strategies. We investigated patterns seasonality stress hangul Kashmir Himalaya, India. used fecal...
ABSTRACT Past climate change is one of the important factors influencing primate speciation. Populations various species could have risen or declined in response to these climatic fluctuations. Northeast India harbors a rich diversity primates, where such fluctuations can be implicated. Recent advances modeling as well genomic data analysis has paved way for understanding how accumulate at particular geographic region. We utilized methods explore this unique region relation past change. To...
Air-breathing catfishes of the family Clariidae exhibit extraordinary adaptations that enable them to survive outside water for extended periods, yet genetic and genomic basis these remain poorly understood. To study adaptations, we sequenced assembled two high-quality genomes clariid species, Clarias gariepinus dussumieri compare with previously available 23 catfish species across nine families. By reconstructing whole-genome phylogeny examining patterns positive selection gene evolution,...
Cyanobacteria play vital roles in aquatic ecosystems by driving photosynthesis, nitrogen fixation, carbon sequestration, and forming symbiotic relationships with diverse organisms. However, their proliferation can trigger harmful algal blooms, posing risks to biodiversity public health. Despite ecological significance, the interplay between cyanobacterial genomic traits ecosystem dynamics remains poorly resolved. Here, we employed culture-independent metagenomic approaches reconstruct...
Tigers continue to face unprecedented threats their existence due poaching, habitat loss, fragmentation and anthropogenic disturbances. The present study examines the physiological stress response of tigers activities including wildlife tourism in Bandhavgarh Tiger Reserve Kanha using faecal glucocorticoid metabolite (fGCM) measurement. We collected a total 341 samples from both reserves during non-tourism periods. Data on various disturbances like number vehicles visitors were also...
India, the country with largest population of dairy cows in world, has a policy retiring abandoned and non-lactating shelters, but level provision for their welfare these shelters is unclear. Cows 54 across India were assessed historic evidence physiological stress, through determination hair cortisol 540 samples from 10 each shelter by enzyme immunoassay. Animal-based resource-based measures recorded correlations investigated multivariable analysis. High concentrations associated dung lying...
Personalized genome sequencing has revealed millions of genetic differences between individuals, but our understanding their clinical relevance remains largely incomplete. To systematically decipher the effects human variants, we obtained whole data for 809 individuals from 233 primate species, and identified 4.3 million common protein-altering variants with orthologs in human. We show that these can be inferred to have non-deleterious based on presence at high allele frequencies other...
Genetic isolation of populations is a potent force that helps shape the course evolution. However, small in isolation, especially fragmented landscapes, are known to lose genetic variability, suffer from inbreeding depression and become genetically differentiated among themselves. In this study, we assessed diversity lion-tailed macaques (Macaca silenus) inhabiting landscape Anamalai hills examined structure species across its distributional range Western Ghats. We sequenced around 900 bases...
Asian elephant (Elephas maximus) populations, both in the wild and captivity, have been continually declining over decades. The present study examined physiological stress response of captive elephants relation to body condition score different working conditions. A total 870 dung samples 37 (24 males 13 females) from four facilities were collected examine fecal glucocorticoid metabolite concentrations (fGCM). forest camps with exposure natural habitats had a higher than those more confined...
The present paper describes, to our knowledge for the first time, successful collection and evaluation of semen from Indian white-backed vulture (Gyps bengalensis), a critically endangered bird. Over period 2 yr, was collected using manual massage method evaluated volume, pH, sperm concentration, percentage normal/abnormal spermatozoa, motile spermatozoa. It appears that concentration spermatozoa in vultures are low compared those other birds. Tyrode medium supplemented with albumin,...
