Amur tiger (Panthera tigris altaica) energetic requirements: Implications for conserving wild tigers

Biological Conservation, 2014
Abstract The Global Tiger Recovery Program has identified increasing prey populations as a crucial component of recovering wild tiger numbers because prey density is a key determinant of tiger density, especially for Amur tigers (Panthera tigris altaica) living at the northern limit of tiger distribution, where both tiger and prey densities are the ...

Inbreeding status and implications for Amur tigers

Animal Conservation, 2021
AbstractInbreeding more likely occurs in small, isolated and endangered populations, and may influence the sustainable survival of a population. As the Amur tiger Panthera tigris altaica population in China experienced a severe decline in the 1990s, the recovering population may be prone to inbreeding and its potential impacts on population health ...

YOLO-mini-tiger: Amur Tiger Detection

Proceedings of the 2020 International Conference on Multimedia Retrieval, 2020
In this paper, we present our solution for tiger detection in the 2019 Computer Vision for Wildlife Conservation Challenge (CVWC2019). We introduce an efficient deep tiger detector, which consists of the convnet channel adaptation method and an improved tiger detection method based on You Only Look Once version 3 (YOLOv3).

Adaptation of the Gut Microbiota of Amur Tigers to a Special Diet

Current Microbiology, 2021
The microorganisms inhabiting the gastrointestinal tract play important roles in many host physiological processes, including the absorption and metabolism of nutrients and immune function. The Amur tiger (Panthera tigris altaica) is listed by the International Union for the Conservation of Nature (IUCN) as a threatened species. Efforts are underway to

Sertoli Cell Tumour in an Amur Tiger

Journal of Comparative Pathology, 2001
The histological and immunohistochemical characteristics of a malignant Sertoli cell tumour in a 17-year-old Amur tiger (Panthera tigris altaica) are described. Histological examination of the primary lesion in the right testis and metastatic lesions throughout the internal organs showed a variable cellular pattern with an admixture of tubular ...

Effects of Roads and Human Disturbance on Amur Tigers

Conservation Biology, 2002
Abstract: Understanding the effects of human disturbance on endangered wildlife populations is critical to their conservation. We examined the effects of roads and human disturbance on the survivorship and foraging efficiency of Amur tigers (   Panthera tigris altaica ) on

Geoecological problems of the Amur tiger saving

Geology and Environment, 2021
Activities of the government and society have an impact on the population of the Amur tiger. Related processes of recession, stabilization and growth of the number of animal species are analyzed. The main attention is focused on the legal basis and promotion of preservation and protection of the Amur tiger.

Vocalization in a neonatal Amur tiger cub.

The Journal of the Acoustical Society of America, 2010
Although the acoustical features of a small number of calls representing the vocal repertoire of adult tigers have been studied and reported, calls produced by developing tigers representing any subspecies have not been described. In that light, the acoustical features of calls produced by an Amur cub during the first two postnatal weeks of life will ...

Part-Pose Guided Amur Tiger Re-Identification

2019 IEEE/CVF International Conference on Computer Vision Workshop (ICCVW), 2019
In this paper, we present our solution to tiger re-identification (re-ID) in both the plain and the wild tracks in the 2019 Computer Vision for Wild life Conservation Challenge (CVWC2019). We introduce a novel part-pose guided framework for the tiger re-ID task, which consists of two part streams and one full stream based on the pose characteristics of

Amino acid sequence of the Amur tiger prion protein

Virus Research, 2006
Prion diseases are fatal neurodegenerative disorders in human and animal associated with conformational conversion of a cellular prion protein (PrP(C)) into the pathologic isoform (PrP(Sc)). Various data indicate that the polymorphisms within the open reading frame (ORF) of PrP are associated with the susceptibility and control the species barrier in ...
