1. Several conservation initiatives are aiming to improve the status of rapidly dwindling populations tiger Panthera tigris. However, possible cascading effects intra-guild competition on other sympatric carnivores rarely considered while planning such recovery programmes. 2. In this study, we examine how, following reduction anthropogenic pressures by relocation pastoralists, a recovering population affects leopards pardus in Chilla Range Rajaji National Park (RNP), India. By combining data...
Abstract Aim Climate change alters the water cycle, potentially affecting distribution of species. Using an ensemble species models (SDMs), we predicted changes in Asian elephant South Asia due to increasing climatic variability under warming climate and human pressures. Location India Nepal. Methods We compiled a comprehensive geodatabase 115 predictor variables, which included climatic, topographic, pressures land use, at resolution 1 km 2 , extensive database on current elephants. For...
Abstract Many small carnivores include rodents in their diet. However, due to varying evolutionary strategies, differ metabolism and energy requirements. Hence, comparisons of diet between would be more meaningful if the body size energetics predators are considered. The three (jungle cat Felis chaus ; caracal Caracal golden jackal Canis aureus ) from a semi‐arid part western India was studied through scat analysis, importance estimated as percentage daily requirement. Although frequency...
Food habits of tigers Panthera tigris in terms prey abundance were studied the semi‐arid deciduous forests Ranthambhore National Park, western India, between November 2000 and April 2001. Wild availability was assessed by line transects ( n =8) selection determined from analysis scats =109). Compared to some other parts country, found be high at 96.65 animals km −2 . Chital Axis axis most abundant wild study area, followed common langur Presbytis entellus , sambar Cervus unicolor nilgai...

Tiger Panthera tigris populations have declined dramatically in the Terai Arc Landscape (TAL; India and Nepal), remaining are highly fragmented endangered. As part of a research program to aid tiger management by identifying critical areas for conservation, we aimed 1) identify factors which affect distribution tigers TAL; 2) explore role spatial scale habitat selection; 3) map potentially suitable habitats; 4) assess quality potential corridors linking habitats. We used an approach based on...
Background: Menstrual hygiene is a multi-dimensional concept. Social inhibitions and the negative attitude of people in discussing menstruation related issues openly prevents adolescent girls from getting right kind information. Methods: We conducted school based cross sectional study Sarvodaya Kanya Vidyalaya North Delhi to assess understanding among going by using pre- designed, pre-tested, self - administered questionnaire Hindi language August November 2023 (4 months). Students classes...
The Sundarbans tiger inhabits a unique mangrove habitat and are morphologically distinct from the recognized subspecies in terms of skull morphometrics body size. Thus, there is an urgent need to assess their ecological genetic distinctiveness determine if tigers should be defined managed as separate conservation unit. We utilized nine microsatellites 3 kb four mitochondrial DNA (mtDNA) genes estimate variability, population structure, demographic parameters visualize historic contemporary...
Niches of 2 cervids (chital, Axis axis and sambar, Cervus unicolor) bovids (nilgai, Boselaphus tragocamelus chinkara, Gazella bennetti) from semiarid forests in western India were studied for habitat use food habits. Habitat was analyzed by discriminant analysis using 20 variables, habits investigated analyzing undigested plant remains pellets. Cervids differentiated primarily according to vegetation terrain features, the deer species showed separation diet. The selected forested areas,...
Linnaeus)over most of their range. While considerable conserva-tion investment is primarily targeted towards recoveringthe dwindling populations tigers (Dinerstein et al.2007), our understanding the potentially cascadingeffects human-induced changes to onecarnivore species on entire carnivore community(Smith al. 2003) remains poor. Though leopards maynot be as adversely affected under deterioratinghabitat conditions (Ramakrishnan 1999), con-tinual loss habitat and intense poaching for...
Asian elephants are endangered while they have faced ~70% population decline in India the last 60 years. Climate change projections indicate exacerbation of ongoing habitat loss (>40%) by 2070, potentially impacting genetic structure wild across India. Therefore, we provide consolidated baseline data on diversity and four eco-regions India, i.e., north-western (NW), north-eastern (NE), east-central (ECI), southern (SI), to identify populations at greater risk further divergence. We genotyped...

This study analysed buffaloes from north-east India and compared their nuclear mitochondrial DNA variations with of mainland India, China, Mediterranean South-East Asia. Microsatellite genotypes 338 including 210 six Indian buffalo populations three breeds were to evaluate genetic structure evolutionary relationships. Phylogenetic analysis multidimensional scaling plot pairwise FST revealed the clustering all swamp-type Lower Assamese (significantly hybrid type) in one plane river another...
