To study the population characteristics, distribution and habitat use of the Yellow-headed tortoise, intensive search of forest floor in possible habitats areas were carried out based on prior information and knowledge over four months (June-September, 2012) and seven months (March-September, 2013). Upon capture, morphometric measurements, weighed and sex of tortoise were recorded. Tortoises were classified as hatchlings, juveniles and adults based on their size. Adult tortoises were sexed as male if plastron was concave. Age estimation was done by counting the annuli rings on the pleural scutes and marked by filling notches in the marginal scutes of the carapace. Overall, 75 tortoises (38 male, 27 female and 10 juvenile) were ca...

Long-distance dispersal has significant implications for ecosystem functioning, and such movement becomes challenging while navigating through a heterogeneous and human-dominated landscape. Here, we describe one of the longest dispersal journey by a sub-adult male tiger through GPS telemetry in Central India. We analyzed movement metrics, directionality, and space use during three behavioural stages of dispersal. We also used the clustering method to identify resting and kill sites (n = 89). T1-C1 dispersed a straight-line distance of 315 km over 225 days, moving an average 8.4 km/day and covering a cumulative displacement of~̵̴ 3000 km. Movement during post-dispersal was higher (mean = 465.6 m/h) than those during dispersal (mean = 376.6 m/h) and pre-dispersal (mean = 132.2 m/h), respectively. Moreover, movement during the night was significantly faster than during the d...
