Assessing environmental DNA metabarcoding and camera trap surveys as complementary tools for biomonitoring of remote desert water bodies

Environmental DNA, Journal Year: 2021, Volume and Issue: 4(3), P. 580 - 595

Published: Dec. 29, 2021

Abstract Biodiversity assessments are indispensable tools for planning and monitoring conservation strategies. Camera traps (CT) widely used to monitor wildlife have proven their usefulness. Environmental DNA (eDNA)‐based approaches increasingly implemented biomonitoring, combining sensitivity, high taxonomic coverage resolution, non‐invasiveness easiness of sampling, but remain challenging terrestrial fauna. However, in remote desert areas where scattered water bodies attract species, which release into the water, this method presents a unique opportunity detection. In order identify most efficient given study system, comparative studies needed. Here, we compare CT metabarcoding samples collected from two ecosystems, Trans‐Altai Gobi Mongolia Kalahari Botswana. We recorded with visiting patterns studied correlation biodiversity captured eDNA approach. The aim present was threefold: (a) investigate how well waterborne captures signals fauna environments, been so far neglected terms biomonitoring efforts; (b) distinct such environments; (c) draw recommendations future eDNA‐based biomonitoring. found significant correlations between methodologies describe detectability score based on variables extracted data wildlife. This supports use these ecosystems encourages further research integrate methodology

Understanding carnivore interactions in a cold arid trans‐Himalayan landscape: What drives co‐existence patterns within predator guild along varying resource gradients?

Ecology and Evolution, Journal Year: 2023, Volume and Issue: 13(5)

Published: May 1, 2023

Abstract Predators compete for resources aggressively, forming trophic hierarchies that shape the structure of an ecosystem. Competitive interactions between species are modified in human‐altered environment and become particularly important where introduced predator can have negative effects on native prey species. The trans‐Himalayan region northern India has seen significant development tourism associated infrastructure over last two decades, resulting many changes to natural setting landscape. While tourism, combined with unmanaged garbage facilitate red fox ( Vulpes vulpes ), it also allows free‐ranging dogs Canis lupus familiaris mesopredator thrive, possibly more than fox. We look at little‐known competitive dynamics these meso‐carnivores, as well their intra‐guild region's top carnivores, snow leopard Panthera uncia ) Himalayan wolf chanco ). To study four we performed multispecies occupancy modeling analyzed spatiotemporal predators using camera trap data. collected scat samples calculate dietary niche overlaps determine extent competition food carnivores. found that, after controlling habitat covariates, site use was related positively use, but negatively dog use. In addition, predators, is, wolf, while themselves As anthropogenic impacts increase, find coexist this resource‐scarce landscape through or segregation, implying limited resources. Our research adds scant ecological knowledge improves our understanding community ecosystems.

Effects of free‐ranging livestock on occurrence and interspecific interactions of a mammalian community

Ecological Applications, Journal Year: 2022, Volume and Issue: 32(7)

Published: April 26, 2022

Abstract Mammalian communities inhabiting temperate grasslands are of conservation concern globally, especially in Central Asia, where livestock numbers have dramatically increased recent decades, leading to overgrazing and land‐use change. Yet, how this pervasive presence herds affects the community wild mammals remains largely unstudied. We used systematic camera trapping at 216 sites across remote, mountainous areas Mongolian Altai Mountains assess spatial temporal patterns occurrence interspecific relationships within a mammalian that includes different categories livestock. By adopting recently proposed multispecies occupancy model incorporates correlation occupancy, we found several statistically strong correlations among species pairs, with majority involving The sign such associations was markedly species‐dependent, larger concern, namely, snow leopard Siberian ibex, avoiding presence. As predicted, evidence positive between predators their respective main prey. Contrary our expectations, number intraguild pairs also showed co‐occurrence, no spatiotemporal niche partitioning. Overall, study suggests encroaching into protected influences whole local mammals. Though pastoralism has coexisted wildlife for millennia central Asian grasslands, findings suggest policies practices decrease pressure husbandry on needed, special attention large species, as its prey, which seem be particularly sensitive

Changes in ecological conditions may influence intraguild competition: inferring interaction patterns of snow leopard with co-predators

Background Large-scale changes in habitat conditions due to human modifications and climate change require management practices consider how species communities can alter amidst these changes. Understanding interactions across the gradient of space, anthropogenic pressure, season provide opportunity anticipate possible dynamics changing scenarios. We studied interspecific carnivore a high-altitude ecosystem over seasonal (summer winter) resource gradients (livestock grazing) assess impact abiotic biotic settings on coexistence. Methods The study was conducted Upper Bhagirathi basin, Western Himalaya, India. analyzed around 4 years camera trap monitoring data understand spatial temporal snow leopard with common woolly wolf were assessed greater trans-Himalayan habitats, respectively. used two occupancy models interactions, circadian activity patterns overlap amongst carnivores. In addition, we examined scats commonalities prey selection. Results result showed that although wolves depend same limited show high overlap, heterogeneity differential use facilitate co-occurrence between predators. Snow spatially independent summer. Conversely, negatively influences space winter. Limited resources (lack livestock), restricted (due cover), similar winter might strong competition, causing avoid each other scale. addition traits size, ecological also play significant role deciding intensity competition large Climate shifts are predicted increase co-predators future. such scenarios, leopards may coexist topographically diverse environment, provided sufficient available.

Seasonal variation in daily activity patterns of snow leopards and their prey

The daily and seasonal activity patterns of snow leopards (Panthera uncia) are poorly understood, limiting our ecological understanding hampering ability to mitigate threats such as climate change retaliatory killing in response livestock predation. We fitted GPS-collars with loggers leopards, Siberian ibex (Capra sibirica: their main prey), domestic goats hircus: common prey) Mongolia between 2009 2020. Snow were facultatively nocturnal season-specific crepuscular peaks: shifted towards night-sunrise during summer, day-sunset winter. leopard was contrast prey, which consistently diurnal. interpret these results relation to: (1) darkness concealment for when stalking an open landscape (nocturnal activity), (2) low-intermediate light preferred predatory ambush steep rocky terrain (dawn dusk (3) adjustments facilitate thermoregulation extreme environment. These suggest that minimise human-wildlife conflict, should be corralled at night dawn It is likely will intensify effects on the leopard's temporal niche future.
