1. Assessing spatial distributions of threatened large carnivores at landscape scales poses formidable challenges because their rarity and elusiveness. As a consequence logistical constraints, investigators typically rely on sign surveys. Most survey methods, however, do not explicitly address the central problem imperfect detections animal signs in field, leading to underestimates true habitat occupancy distribution. 2. We assessed for tiger Panthera tigris metapopulation across c. 38...
Today, most wild tigers live in small, isolated Protected Areas within human dominated landscapes the Indian subcontinent. Future survival of depends on increasing local population size, as well maintaining connectivity between populations. While significant conservation effort has been invested tiger few initiatives have focused landscape-level and understanding effect different landscape elements connectivity. We combined individual-based genetic ecology approaches to address this issue...
There is increasing evidence of the importance multi-use landscapes for conservation large carnivores. However, when carnivore ranges overlap with high density humans, there are often serious challenges. This especially true in countries like India where loss peoples' lives and property to wildlife not uncommon. The leopard (Panthera pardus) a felid that widespread India, sharing human densities. In order understand ecology leopards use landscape nature human-leopard interactions, we studied...
Abstract Male Asian elephants are known to adopt a high-risk high-gain foraging strategy by venturing into agricultural areas and feeding on nutritious crops in order improve their reproductive fitness. We hypothesised that the high risks survival posed increasingly urbanising often unpredictable production landscapes may necessitate emergence of behavioural strategies allow male persist such landscapes. Using 1445 photographic records 248 uniquely identified over 23-month period, we show...
Land use is a key driver of the ongoing biodiversity crisis and therefore also major opportunity for its mitigation. However, appropriately considering diversity land-use actors activities in conservation assessments planning challenging. As result, top-down policy are often criticized lack contextual nuance widely acknowledged to be required effective just action. To address these challenges, we have developed conceptually consistent, scalable land system typology demonstrated usefulness...
Small-sized protected areas face increasing pressures from developmental activities and are often rendered inadequate isolated to conserve wide-ranging species. However, in situations where wildlife persists outside areas, conservation goals may be met by aligning the ecological needs of with socio-economic local communities offsetting losses arising due shared spaces. We explore potential a tea-plantation dominated landscape multiple land-use north-eastern India Asian elephant Indian...
There is increasing evidence of large carnivores using human-use areas, but our understanding their ecology in such landscapes limited. The role wild and domestic prey sustaining populations could be significant currently poorly documented. We studied the composition diet selection leopards ( Panthera pardus) a forest tea-garden landscape north-eastern India where population density greater than 700 people per km 2 average animal 340 animals . Wild was 56 Both were used by proportion to...
Significance Small and isolated populations have low genetic variation due to founding bottlenecks drift. Few empirical studies demonstrate visible phenotypic change associated with drift using data in endangered species. We used genomic analyses of a captive tiger pedigree identify the basis for rare trait, pseudomelanism, tigers. Genome sequencing extensive genotyping noninvasive samples across range revealed unique spatial presence this allele Similipal Tiger Reserve, India. Population...
Background A dearth in understanding the behavior of Asian elephants (Elephas maximus) at scale populations and individuals has left important management issues, particularly related to human-elephant conflict (HEC), unresolved. Evaluation differences decision-making among individual across groups response changing local ecological settings is essential fill this gap knowledge improve our approaches towards conservation elephants. Methodology/Principal Findings We hypothesized certain...
Abstract Small hydropower projects (SHPs) are promoted as environmentally benign alternatives to larger dams; however, the impacts of SHPs have been poorly studied, especially in tropical developing countries, where their growth is being encouraged. This study assessed two on freshwater fish communities Western Ghats biodiversity hotspot India. Two dammed and one undammed tributary Netravathi River, having similar stream order, elevation, surrounding land‐use types, were identified test...
Abstract Large herbivores respond to seasonal changes in resource availability through habitat selection. Understanding variations choice is crucial for targeting conservation efforts, particularly endangered, wide‐ranging species, such as the Asian elephant. We assessed patterns and determinants of elephant use during dry season, a period limitation tropical deciduous forests, Western Ghats Karnataka, India. collected detection/non‐detection data on signs under an occupancy sampling...
Abstract The current protected area (PA) network is not sufficient to ensure long‐term persistence of wide‐ranging carnivore populations. Within India, this particularly the case for species that inhabit nonforested areas since PAs disproportionately over‐represent forested ecosystems. With growing consideration human‐use landscapes as potential habitats adaptable large carnivores, India provides a model studying them in densely populated landscapes, where there little understanding about...
When sighting-based surveys to estimate population densities of large herbivores in tropical dense forests are not practical or affordable, that rely on animal dung sometimes used. This study tested one such dung-based method by deriving from observed six (chital, elephant, gaur, muntjac, sambar, and wild pig) two habitats, dry deciduous (DDF) moist (MDF), within Nagarahole National Park, southern India. Using the program DUNGSURV, pile counts, decay rates estimated field experiments,...
Abstract In biodiversity‐rich landscapes that are developing rapidly, it is generally impossible to delineate land use and prioritize conservation actions in relation the full variability of species their responses anthropogenic activity. Consequently, policy often focuses on protecting habitat used by a few flagship, indicator or umbrella like tigers Panthera tigris Asian elephants Elephas maximus , which potentially leaves out do not share these preferences. We demonstrate an empirical...
Invasive trees in catchments around the world are a source of concern due to their hydrological and ecological impacts. A large number studies have focused on impact dry-season stream discharge enhanced transpiration. The invasive flood risk during extreme rain events, which becoming more frequent climate change, has not been addressed adequately. We examined influence land-cover, canopy cover, other catchment morphological characteristics discharges hilly light, heavy, events. Three years...
Shared spaces in Africa and Asia accommodate both humans big cats. This engenders rare but distinctive cases of human fatalities by lions, tigers, leopards. Among cats, leopards have the widest range occur even among high densities humans. increased potential for encounters with results attacks, exemplified most India where 50% states report injuries deaths due to Himachal Pradesh (HP) state reported 30 lethal 287 non-lethal leopard attacks on per year between 2004 – 2015 (N=317)....
