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.

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.

Serosurvey of Free-ranging Amur Tigers in the Russian Far East [PDF]

Journal of Wildlife Diseases, 2012
Wild Amur tigers (Panthera tigris altaica, n=44) from the Russian Far East were tested for antibodies to feline leukemia virus, feline corona virus (FCoV), feline immunodeficiency virus, feline parvovirus (FPV), canine distemper virus (CDV), Toxoplasma gondii, and Bartonella henselae. Antibodies to FCoV, CDV, FPV, and T. gondii were detected in 43, 15,

Can Wapiti (Cervus elaphus) Browsing Stimulate the Chemical Defense of Taxus cuspidata—A Case of Northeast China Tiger and Leopard National Park

Integrative Zoology, EarlyView.
We study that browsing by wapiti reduces the growth of saplings, and it develop chemical defenses to prevent themselves browsed again. These results reduce our concern about wapiti browse T. cuspidate saplings, and provide basic data for the study of the interaction between them, and also provide theoretical basis for the population restoration and ...

Screening and analyzing genes associated with Amur tiger placental development

Genetics and Molecular Research, 2014
The Amur tiger is a unique endangered species in the world, and thus, protection of its genetic resources is extremely important. In this study, an Amur tiger placenta cDNA library was constructed using the SMART cDNA Library Construction kit. A total of 508 colonies were sequenced, in which 205 (76%) genes were annotated and mapped to 74 KEGG pathways,

Translocation of problem Amur tigers Panthera tigris altaica to alleviate tiger-human conflicts [PDF]

Oryx, 2005
We translocated four Amur tigers Panthera tigris altaica captured after killing domestic animals or attacking people; two were released immediately and two following 162 and 388 days rehabilitation. All were radio-collared and released 150–350 km from their capture site.
