Comparison of methods for estimating Amur tiger abundance [PDF]

Wildlife Biology, 2017
The Amur tiger Panthera tigris altaica is endangered throughout its range. Estimating abundance to monitor population trends is needed to judge success of conservation efforts. However, low densities and elusive behavior make precise estimates difficult to achieve.

Does the territorial behaviour of the Amur tiger affect the accuracy of occupancy estimation?

bioRxiv, 2023
1. Accurate estimates of wildlife distributions and population persistence are essential for conservation programs. Occupancy models that account for detection probability have been used to characterize the occupancy and habitat selection of imperilled ...

Spatio-temporal coexistence of sympatric mesocarnivores with a single apex carnivore in a fine-scale landscape

Global Ecology and Conservation, 2020
Mesocarnivores uniquely and profoundly impact ecosystem function, structure, and dynamics. Sympatric species tend to spatially and temporally partition limited resources to facilitate coexistence.

Re-Identification of Amur Tigers by Combining Multi-branch and Multi-granularity Features

Journal of Harbin University of Science and Technology, 2023
In order to solve the problem of insufficient detailed feature extraction in the re-identification of the Amur tiger, a re- identification model of the Amur tiger, CMM-NET, was proposed, which combined multi-branch and multi-granularity features.

Does presence of top predator improve forest birds' survival and diversity? An ecological case study assessing umbrella conservational impact of tiger using carrion

Global Ecology and Conservation
After hunting, predators tend to leave a large amount of carrion behind. It is widely reported that this resource is commonly used by various species in the ecosystem and is essential for the survival of scavengers, particularly in winter.

Integrating direct anthropogenic disturbances and habitat connectivity to guide the restoration of the Amur tiger population in a newly established national park in China

Landscape Ecology
China initiated its national parks in 2016 for safeguarding biodiversity and ecosystem integrity. The newly established Northeast Tiger and Leopard National Park (NTLNP) is essential for saving endangered large cats, but its adequacy for supporting apex ...

From Amur tiger occurrence in the Greater Khingan Mountains to doing an overall conservation for its in China

Conservation Science and Practice, 2022
This study analyzes the new distribution of the Amur tiger in China after the discovery of the Amur tiger's footprints in the Greater Khingan Mountains region (GKM), where there has been no tiger distribution since the 1960s.

Gait Recognition of Amur Tiger Based on Deep Learning

Journal of Physics: Conference Series, 2021
Abstract The gait of Amur tiger was studied through video images, and a more accurate individual recognition system of Wild Amur tiger was given on the premise of supplementing pattern recognition technology. Through further research on the common gait of Amur tiger, the basic information database was established to realize the ...

Local Attitudes Toward Amur Tiger (Panthera tigris altaica) Conservation in the Russian Far East

Conservation & Society, 2022
Public support is a necessary component of large carnivore conservation. We analysed public opinion on Amur tigers, Panthera tigris altaica, in Russia's Far East, the northernmost stronghold of the world's rarest big cat.
