“…Telonics fixed 79% of scheduled locations but failed to uplink data to the Argos satellites. Therefore, stored data onboard were downloaded directly from collars after tigers were recaptured (Rozhnov et al ). In all, 4358 locations were obtained from 15 transmitters, with locations/tiger ranging from 10 to 1222, and the operational life of collars ranging from 31 to 353 days (Table ) on animals ranging from 18 months to 6 years.…”

“…Our observations suggest that the size and location of female core areas generally remain stable over time. For instance, the core area of female PT02F's home range in 2008, when she was with cubs, was essentially the same as in 2009 when she was without cubs (Rozhnov et al ). These results are in concordance with those of Hojnowski et al (), who found high site fidelity of female Amur tigers both seasonally and over multiple years.…”

“…Collectively, these 2 areas represent the southwesternmost portions of the Amur tiger range. Amur tiger population density in Ussuriskii Reserve fluctuated during the study period from 0.112 individuals to 0.586 individuals per 100 km 2 (Hernandez‐Blanco et al ), while density in southwest Primorye was estimated to be 0.34 individuals per 100 km 2 (Rozhnov , unpubl. data).…”

“…Even with aerial telemetry, movements of animals out of core areas can be missed, reducing estimates of home range size and overlap with neighbors. The development of GPS transmitters that can obtain multiple accurate locations regularly over 24‐h periods and transmit data through satellite communication has provided new insights into the movements and spatial structure of carnivore populations (Fancy et al ; Mech & Barbe ; Rozhnov et al , ; Petrunenko et al ).…”

To better understand the spatial structure of Amur tigers (Panthera tigris altaica) at the southern edge of their range we fitted 14 tigers (6♀♀ and 8♂♂) with 15 GPS-Argos collars between 2008 and 2011 in 2 study sites: the Ussuriskii Reserve of southern Sikhote-Alin and the Land of the Leopard National Park in southwest Primorye, Russian Far East. Fixed kernel estimates of male home ranges were larger than those of female home ranges (P < 0.05 [mean 95% fixed kernel(♀) = 401 ± 205 km(2) ; mean 95% fixed kernel(♂) = 778 ± 267 km(2)]). The home range size of females varied greatly, but on average was similar to estimates derived from earlier work further north. Low overlap of adjacent home ranges suggested that females retained exclusive territories. Real core areas of females overlapped only slightly, and remained stable over multiple years. The home ranges of adult males were smaller than those of males to the north, and in contrast to previous studies, high overlap among males indicated the absence of territoriality. Nonetheless, real core areas of males did not overlap, suggesting some spatial separation. In comparison to other tiger populations and other areas of the Russian Far East, the sex ratio in our 2 study areas was highly skewed towards males. We believe this skewed sex ratio resulted in the dissolution of territoriality of males due to an inability to defend individual females, with males resorting to scramble competition for mates. Continued monitoring of these sites to determine whether shifts in the sex ratio might result in a return to male territoriality would provide confirmation of our tentative hypothesis.

“…Better conserva-tion of large felids, which often act as the flagship species of an ecosystem, is dependent on reliable estimates of population size and trend. It is challenging to derive reliable estimates of population size and demography for large felids generally due to low densities (Barlow et al 2009), large home ranges and their elusive behavior (Rozhnov et al 2011). Camera trapping methods have recently been widely adopted to produce better population estimations of large carnivores with statistical robustness (Pesenti & Zimmermann 2013;Selvan et al 2014).…”

As an apex predator the Amur tiger (Panthera tigris altaica) could play a pivotal role in maintaining the integrity of forest ecosystems in Northeast Asia. Due to habitat loss and harvest over the past century, tigers rapidly declined in China and are now restricted to the Russian Far East and bordering habitat in nearby China. To facilitate restoration of the tiger in its historical range, reliable estimates of population size are essential to assess effectiveness of conservation interventions. Here we used camera trap data collected in Hunchun National Nature Reserve from April to June 2013 and 2014 to estimate tiger density and abundance using both maximum likelihood and Bayesian spatially explicit capture-recapture (SECR) methods. A minimum of 8 individuals were detected in both sample periods and the documentation of marking behavior and reproduction suggests the presence of a resident population. Using Bayesian SECR modeling within the 11 400 km(2) state space, density estimates were 0.33 and 0.40 individuals/100 km(2) in 2013 and 2014, respectively, corresponding to an estimated abundance of 38 and 45 animals for this transboundary Sino-Russian population. In a maximum likelihood framework, we estimated densities of 0.30 and 0.24 individuals/100 km(2) corresponding to abundances of 34 and 27, in 2013 and 2014, respectively. These density estimates are comparable to other published estimates for resident Amur tiger populations in the Russian Far East. This study reveals promising signs of tiger recovery in Northeast China, and demonstrates the importance of connectivity between the Russian and Chinese populations for recovering tigers in Northeast China.

The fine‐scale movement pattern of Amur tiger (Panthera tigris altaica) responds to winter habitat permeability

The number of Amur tigers living in protected regions is increasing, and China has achieved significant progress in this regard, especially at the Sino‐Russia border region around Hunchun where most of the Amur tigers are found in China. However, there is a need to increase the dispersal of Amur tigers further from the border as the region is not large enough to support the sustainable survival of the population. In the winter of 2012–2015 and January 2022, we tracked 38 Amur tiger snow traces and performed line transect and camera trap surveys in Hunchun to assess Amur tiger movements in response to the landscape and its permeability at fine scales. Our results showed that towns, shrubs, and forest roads are the main factors influencing Amur tiger movements. Furthermore, tiger paths were characterized by lower tortuosity in preferred habitats. This provides information for small‐scale habitat modification to increase landscape permeability and facilitate dispersal.
