- An ecological study in the buffer zone of the Corbett Tiger Reserve: Tiger abundance and cattle depredation
The paper aimed to find out the abundance of tigers in various forest block of the Corbett Tiger Reserve and intensity and pattern of livestock depredation by the tiger in and around the Corbett Tiger Reserve. The study find out that the forest blocks located in the southern part of the tiger reserve has high abundance of tiger. The study also find out the tiger killed maximum number of livestock in the monsoon season.

- Density estimation of tiger and leopard using spatially explicit capture–recapture framework
The paper modeled the CR data of tiger (Panthera tigris tigris) and leopard (Panthera pardus fusca) in the SECR framework with biotic and abiotic covariates likely believed to influence their densities. An effort of 2,211 trap nights resulted in the capture of 33 and 38 individual tigers and leopards. A total of 95 and 74 detections of tigers and leopards were achieved using 35 pairs of camera traps. Tiger and leopard density were estimated at 4.71 ± 1.20 (3.05–5.11) and 3.03 ± 0.78 (1.85–4.99) per 100 km2. Our results show that leopard density increased with high road density, high terrain ruggedness and habitats with high percentage of cropland and natural vegetation. The tiger density was positively influenced by the mosaic of cropland and natural vegetation. This study provides the first robust density estimates of tiger and leopard within the study area. Our results support the notion that large carnivores can attain moderate densities within human-dominated regions around protected areas relying on domestic livestock.
- Multi-scale habitat selection and impacts of climate change on the distribution of four sympatric meso-carnivores using random forest algorithm The paper used a supervised machine learning algorithm, random forest (RF), to assess the habitat relationships of Asiatic wildcat (Felis lybica ornata), jungle cat (Felis chaus), Indian fox (Vulpes bengalensis), and golden-jackal (Canis aureus) at ten spatial scales (500–5000 m) in human-dominated landscapes. We calculated out-of-bag (OOB) error rates of each predictor variable across ten scales to select the most influential spatial scale variables. The scale optimization (OOB rates) indicated that model performance was associated with variables at multiple spatial scales. The species occurrence tended to be related strongest to predictor variables at broader scales (5000 m). Multivariate RF models indicated landscape composition to be strong predictors of the Asiatic wildcat, jungle cat, and Indian fox occurrences. At the same time, topographic and climatic variables were the most important predictors determining the golden jackal distribution. Our models predicted range expansion in all four species under future climatic scenarios
- Seasonal variation in the diet of sloth bears in Bandhavgarh Tiger Reserve, Madhya Pradesh, India Download PDF
Paper focused on seasonal variation in food habits of sloth bears (Melursus ursinus) in the human dominated buffer zone of the Bandhavgarh Tiger Reserve, Madhya Pradesh, India. Under the study 109 sloth bear scats from summer and 103 from winter to characterize the seasonal variation in food habits .We used the Index of Relative Importance (IRI) to determine the importance of each food item. Tendu (Diospyros melanoxylon) fruits had the highest IRI score in summer and termites had the highest IRI score in winter. There was a distinct seasonal variation in the food habits of the sloth bears (?2 = 143.3, 10 df, P < 0.01). Insects (termites and ants) were the most important food source for sloth bears, contributing 41% and 95% of the Estimated Dietary Energy Content (EDEC) during summer and winter, respectively. Study found that sloth bears fed primarily on the fruits of 6 plant species in summer, including the fruits of the invasive weed, Lantana camara. Fruits of amaltas (Cassia fistula) and char (Buchanania cochinchinensis) were consumed in a lower proportion than available, whereas the fruits of tendu were consumed in proportion to availability. Sloth bears had not consumed any large vertebrate species. The food items stabilization curve showed that 70 scats in summer, and 80 scats in winter, were required to depict the diet of sloth bear adequately. Consumption of L. camara by sloth bears, as well as other wildlife species, has strong management implications in terms of seed dispersal and the spreading of this invasive weed.
- Multi-scale habitat modelling and predicting change in the distribution of tiger and leopard using random forest algorithm
Paper focused on habitat suitability modelling of tiger and leopard in Bandhavgarh Tiger Reserve. Multi-scale habitat suitability modelling was used to determine the suitable habitat available to large predators. Multi-scale habitat suitability models (HSM) can inform forest managers to aim their conservation efforts at increasing the suitable habitat for tigersby providing information regarding the scale-dependent habitat-species relationships. This study investigates the multiscale habitat relationships of tigers and leopards and the impacts of future climate change on their distribution using a machine-learning algorithm random forest (RF).
