Biodiversity conservation and human well-being are tightly interlinked; yet mismatches in the scale at which both priorities are planned have led to biodiversity loss, erosion of ecosystem services, and declining human quality of life. In India, <5% of the land area is effectively protected for conservation, while the rest is impacted by the second...
Article
Substantial research and conservation resources are invested towards studying, protecting, and managing carnivore populations, globally. But scholarly investigations that link the outcomes of ecological research and their applications are not commonplace. Such syntheses can have implications for large predator management and human well-being. India...
Article
Full-text available
Large carnivores are important for maintaining ecosystem integrity and attract much research and conservation interest. For most carnivore species, estimating population density or abundance is challenging because they do not have unique markings for individual identification. This hinders status assessments for many threatened species, and calls f...
Article
Elevated rates of anthropogenic impacts on land‐use regimes have pushed terrestrial megafauna to the brink of extinction. Consequently, it is critical to adopt conservation approaches that safeguard individual populations, while retaining connectivity among these populations. Conserving spatially structured populations of imperiled species at large...
Article
Global land-use changes and rapid infrastructure development necessitate identification and conservation of wildlife corridors. Connectivity through corridors is shaped by species' structural, ecological and behavioral constraints. In multi-use landscapes, species' interactions with humans could additionally influence connectivity. Using the tiger...

Full-text available
Our study titled "The balancing act: Maintaining leopard-wild prey equilibrium could offer economic benefits to people in a shared forest landscape of central India" used an occupancy framework to provide baseline information on patterns and determinants of leopard occurrence and conflict in a human-dominated landscape. We also examined the role of...
Article
• Large carnivores face high extinction risks, often exacerbated by the absence of adequate information on their ecological requirements, and the high economic and socio‐political commitments that their conservation warrants. Country‐scale conservation plans can serve as effective frameworks to prioritise areas, actions, and conservation investment...
Article
Full-text available
Conservation interventions in developing countries are frequently thwarted by socio-economic agendas, severely limiting the scope and rigor of biodiversity and habitat conservation. Very few ecological assessments incorporate human interests in conservation prioritization, creating asynchrony between planning and implementation. For conservation ac...
Article
Full-text available
Wildlife crimes pertaining to lesser-known species do not usually garner adequate focus or interest by enforcement and conservation agencies. Additionally, illegal wildlife trade fuelled by religious beliefs in sorcery and superstition is an oft-neglected field of research. To draw attention to these two broad issues, we provide a baseline analysis...
Article
Livestock depredation is the most ubiquitous type of negative interaction between humans and carnivores. We conducted a range-wide assessment linking diet patterns of the endangered dhole Cuon alpinus, with livestock consumption and human-dhole interactions. We first performed a reanalysis of dhole diet data from all published studies (1973-2013) i...

Our study titled “Land sharing potential of large carnivores in human‐modified landscapes of western India” used an occupancy framework to provide baseline information on patterns and determinants of large carnivore presence in human‐use landscapes. In their letter, Shrotriya et al. raise concerns about our survey design, distort our inferences, an...
Article
Despite the efforts invested in their conservation, the status of many threatened carnivores in key conservation landscapes remains unknown. The dhole Cuon alpinus is an Endangered social carnivore whose geographical range has contracted by c. 80% since the early 20th century. North-east India is a critical link between South Asian and South-east A...
Article
Full-text available
Many carnivores inhabit human-dominated landscapes outside protected reserves. Spatially explicit assessments of carnivore distributions and livestock depredation patterns in human-use landscapes are crucial for minimizing negative interactions and fostering coexistence between people and predators. India harbours 23% of the world's carnivore speci...
Article
Full-text available
The current protected area (PA) network is not sufficient to ensure long‐term persistence of wide‐ranging carnivore populations. Within India, this is particularly the case for species that inhabit nonforested areas since PAs disproportionately over‐represent forested ecosystems. With growing consideration of human‐use landscapes as potential habit...
Article
Full-text available
Most large carnivore populations currently occur in heterogeneous landscapes, with source populations embedded in a matrix of human-dominated habitats. Understanding changes in distribution of endangered carnivores is critical for prioritizing and implementing conservation strategies. We examined distribution and dynamics of a dhole Cuon alpinus me...
Article
Full-text available
Highly variable patterns in temperature and rainfall events can have pronounced consequences for small mammals in resource‐restricted environments. Climatic factors can therefore play a crucial role in determining the fates of small mammal populations. We applied Pradel's temporal symmetry model to a 21‐year capture–recapture dataset to study popul...
Article
Full-text available
Occupancy models that account for detection probability are important analytical tools in conservation monitoring. Traditionally, occupancy models relied on detection/non-detection data generated from temporal replicates for estimating detectability. Due to logistical challenges and financial costs involved, many large-scale field studies instead u...

The dhole Cuon alpinus is an Endangered carnivore, whose population status is hitherto undetermined across most of its range. We update information on dhole distribution patterns in the northern Western Ghats, India, which forms the northern range limits for the species in the region. We use two sources of data: a landscape-scale (7000km 2) habitat...
Article
Estimating animal distributions and abundances over large regions is of primary interest in ecology and conservation. Specifically, integrating data from reliable but expensive surveys conducted at smaller scales with cost-effective but less reliable data generated from surveys at wider scales, remains a central challenge in statistical ecology. I...
Article
Full-text available
Species within a guild vary their use of time, space and resources, thereby enabling sympatry. As intra-guild competition intensifies, such behavioural adaptations may become prominent. We assessed mechanisms of facilitating sympatry among dhole (Cuon alpinus), leopard (Panthera pardus) and tiger (Panthera tigris) in tropical forests of India using...
Article
Full-text available
The dhole Cuon alpinus is one of the least studied large carnivores in the world. Unlike many other social canids, dholes occur at low densities in tropical forests. Furthermore, they are wary, and difficult to capture and radio-tag, thereby posing challenges in the field for tracking their movements or making behavioural observations. We conducted...
Article
Full-text available
Globally, protected areas have long been the corner stone of biodiversity conservation efforts. In India's Western Ghats, small and isolated protected areas are embedded in a matrix of multiple land-uses, most of which include agroforests. These agroforests are being increasingly recognized for their supplementary role in conserving wildlife. We ex...
Article
Full-text available
Recovering small populations of threatened species is an important global conservation strategy. Monitoring the anticipated recovery, however, often relies on uncertain abundance indices rather than on rigorous demographic estimates. To counter the severe threat from poaching of wild tigers (Panthera tigris), the Government of Thailand established...
Article
Full-text available
There is increasing evidence of large carnivore presence outside protected areas, globally. Although this spells conservation success through population recoveries, it makes carnivore persistence in human-use landscapes tenuous. The widespread distribution of leopards in certain regions of India typifies this problem. We obtained information on leo...
Article
Full-text available
The status of several small carnivores in Asia remains poorly known because of the lack of rigorous population assessments. The leopard cat Prionailurus bengalensis is one such species assumed to be common and widespread within the Indian subcontinent. We conducted surveys using automated cameras to estimate densities and abundance of leopard cats...
Article
AimInformation on patterns and determinants of spatial distributions remains poorly available for many widespread species of conservation importance. The sloth bear Melursus ursinus in the Indian subcontinent exemplifies this requirement. We aimed at assessing (1) distribution patterns of sloth bears at two spatial scales, (2) ecological and anthro...
