World Environment Day on Sunday is an occasion to assess where we stand in making this planet a more liveable place for us and future generations. Wildlife scientists and conservation experts on the choices we can make today before it becomes too late... A consumer picking a product off a shelf has an immediate impact on distant species and natural ecosystems. And that link brings with it both an environmental peril and opportunity.

Leopards use a wide range of habitats from natural forests to human-dominated landscapes and conflicts sometimes arise from loss of livestock or attacks on people in interface areas. In a fragmented rainforest and plantation landscape in southern India, we examined diet of large carnivores (particularly leopards) using scat analysis with DNA-based identification of predator species, and relative abundance of prey species in different land-uses using transect surveys. Spatio-temporal patterns in conflict and attitudes of local people were analysed from conflict records with the Forest Department and questionnaire surveys in 28 plantation colonies and eight tribal settlements. Large carnivores predominantly (98.1%) consumed wild prey species and domestic prey species contributed <2% to overall prey biomass. Similarly, for leopards four wild prey species (Indian muntjac, Indian spotted chevrotain, sambar, and Indian porcupine) contributed 95.1% of prey biomass, with the rest being minor wild prey species (no livestock in identified scats). In the landscape, wild prey species persisted but varied in relative abundance by land-use type, with forest fragments supporting higher abundances of most species. ... In a 3-year period (2008 – 2010), 32 head of livestock (cow, buffalo, and goat) were reported by respondents as lost to carnivore depredation (economic loss averaging INR 9732 or ~USD 216 per incident). Over the same period, there were eight attacks on people, resulting in three fatalities (all children). Attitudes towards leopards were not affected by incidence of livestock depredation, but related instead to occurrence of attacks on people in the colony. Livestock depredation at a colony was significantly and positively related to livestock numbers, and interactively with distance from protected area (positive) and number of people (negative). To minimise conflicts, we suggest adoption of a combination of measures including better herding, improved livestock corrals, safety precautions for adults and children at night in estates, and proper waste management, besides protection of habitat remnants that sustain wild prey populations. These will help safeguard human life and reduce economic losses, thereby mitigating conflict and promoting human – leopard coexistence in such landscapes.

Large mammals face high risks of anthropogenic extinction owing to their larger body mass and associated life history traits. Recent worldwide mammal declines have highlighted the conservation importance of effective assessments of trends in distribution and abundance of species. Yet reliable data depicting the nature and extent of changes in population parameters is sparse, primarily due to logistical problems in covering large areas and difficulties in obtaining reliable information at large spatial scales, particularly over time. We used key informant surveys to generate detection histories for 18 species of large mammals (body mass > 2 kg) at two points in time (present and 30 years ago) in the Southern subregion of the Western Ghats global biodiversity hotspot. Multiple-season occupancy models were used to assess temporal trends in occupancy, detectability and vital rates of extinction and colonization for each species. Our results show significant declines in distribution for large carnivores, the Asian elephant and endemic ungulates and primates. There is a significant decline in detectability for 16 species, which suggests a decline in their abundance. These patterns of change in distribution and abundance repeat in our assessments of spatial variation in occupancy dynamics between the three contiguous forest complexes and two human-dominated landscapes into which the southern Western Ghats has been fragmented. Extinction rates are highest in the human-dominated landscapes. Declines in abundance for several species suggest the presence of extinction debts, which may soon be repaid with imminent range contractions and subsequent species extinctions unless immediate remedial conservation measures are taken. Detection/non-detection surveys of key informants used in an occupancy modeling framework provide potential for rapid conservation status assessments of multiple species across large spatial scales over time.

The goal of this study was to test whether body-mass based foraging principles, guided by plant available moisture (PAM) and plant available nutrients (PAN), could explain large mammalian herbivore species distribution and richness in India. We tested (1) whether the occurrence of larger-bodied herbivore species increases with PAM, but is independent of PAN, (2) whether the occurrence of smaller-bodied herbivore species decreases with PAM, but increases with PAN, and (3) whether herbivore species richness is highest in areas with intermediate PAM and high PAN. We analyzed the distribution and richness of the 16 large (>10 kg) herbivore species found in sub-Himalayan mainland India. Since the distributions of large herbivores in India have been altered by historic human activity, we only used India's largest 76 protected areas as data points, with respect to PAM (log10(rainfall/potential evapotranspiration)), PAN (soil cation exchange capacity), elevation, tree cover, and fire frequency. Using regression and null models to analyze the data, we found positive relations between PAM and the occurrences of the larger-bodied species (elephant and gaur), and negative relations between PAM and the occurrences of smaller-bodied species (chinkara, four-horned antelope and blackbuck). We also found positive relations between the occurrence of the smaller-bodied species and PAN. Large herbivore species richness in India is highest in Kanha and Indravati, areas with high PAN and intermediate PAM. We found that elevation, tree cover and fire frequency were insignificant predictors of herbivore species richness, although elevation and tree cover explained the distribution of a few species. Based on our null model analyses results, we conclude that moisture and soil nutrients are important in determining large herbivore species distribution and richness in sub-Himalayan India.
