“…The dispersal journey was remarkable for its length, duration, and movement through a highly interspersed mosaic of forested areas and agricultural fields. Evidence of such long‐distance dispersal in tigers has been recorded previously in a few studies through radiotelemetry (VHF and GPS), intensively monitored populations (camera traps) and genetic studies across various landscapes in the Indian subcontinent (Gour et al, 2013; Reddy et al, 2012; Sarkar et al, 2016, 2021; Singh et al, 2021; Smith, 1993). Such movement occurs in both sexes, with males moving longer distances from few kilometers to hundreds of kilometers (Table 3) and can be influenced by various factors.…”

“…The movement behavior during dispersal in a highly interspersed mosaic of forested areas, agriculture fields, and human settlements is rarely documented. Studies on tiger dispersal are limited, and few have described long‐distance dispersal primarily based on camera trap data and VHF/GPS telemetry (Sarkar et al, 2021; Singh et al, 2021; Smith, 1993; Wang et al, 2015). Moreover, genetic studies have shown gene flow over long distances (Anuradha Reddy et al, 2016; Gour et al, 2013; Joshi et al, 2013).…”

Conservation of wide‐ranging species and their movement is a major challenge in an increasingly fragmented world. Long‐distance movement, such as dispersal, is a key factor for the persistence of population, enabling the movement of animals within and between populations. Here, we describe one of the longest dispersal journeys by a sub‐adult male tiger (Panthera tigris) through GPS telemetry in Central India. We analyzed movement metrics, directionality, and space use during three behavioral 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 of 8.38 km/day and covering a cumulative displacement of ~3000 km. Movement rate during post‐dispersal was faster (mean = 0.47 km/h) than during dispersal (mean = 0.38 km/h) and pre‐dispersal (mean = 0.13 km/h), respectively. The overall movement rate during the night (0.44 km/h) was significantly faster than during the day (0.21 km/h). Likewise, during dispersal, the movement was faster (mean = 0.52 km/h) at night than day (0.24 km/h). The average size of clusters, signifying resting and kill sites, was 1.68 ha and primarily away from human habitation (mean = 1.89 km). The individual crossed roads faster (mean = 2.00 km/h) than it traveled during other times. During the post‐dispersal phase, T1‐C1 had a space use of 319.48 km2 (95% dBBMM) in the Dnyanganga Wildlife Sanctuary. The dispersal event highlights the long‐distance and multiscale movement behavior in a heterogeneous landscape. Moreover, small forest patches play a key role in maintaining large carnivore connectivity while dispersing through a human‐dominated landscape. Our study underlines how documenting the long‐distance movement and integrating it with modern technology can improve conservation management decisions.

Tigers are one of the most recognized and charismatic predator on earth, yet their habitats have declined, their numbers are low, and substantial threats to their survival persist. Although, tiger conservation is high priority globally and tigers are generally considered well studied, there has been no comprehensive global assessment of tiger-related publications aimed at identifying trends, assessing their status and pinpointing research gaps. Utilizing PRISMA framework, we conducted an extensive search across multiple databases, including Scopus, Web of Science, and ScienceDirect, to gather research related to Bengal tigers. Following thorough screening, we selected and evaluated 491 articles published between 2010 and 2022 to address these issues. The results show that publications on Bengal tigers have steadily on rise, with an average of 40 papers/year within this period. We found that most research was focused on the theme of tiger biology. Information on leopards and dholes was also frequently associated with tiger research. The highest number of lead authors originated from India (n = 192), where most research was also conducted. Authors from USA (n = 111) and UK (n = 38) were the next most productive, even though tigers are not found in or anywhere near these countries. We demonstrate that there is only limited amount of transboundary research, and that relatively little tiger research is conducted in the forests beyond protected areas. Similarly, very important but the least studied themes ─Poaching, Population and Socio-culture dimension should be the priority of future research efforts. Additionally, research on tourism, economic aspects and technological inputs are essential for the sustainable conservation of Bengal tigers.
