According to Kailash Sankhala, the last white tiger ever seen in the wild was shot in 1958.
Disease can also be a factor: white nose syndrome in bats, for example, is causing a substantial decline in their populations and may even lead to the extinction of a species. [30] Another example is the Devil facial tumour disease , which has devastated populations of Tasmanian devils .
Population control plays an important role in wildlife populations. Based on the species being dealt with, there are numerous ways populations of the wild are controlled. Wildlife contraception is the act of preventing reproduction in the wild, which subsequently decreases populations. An example of this includes the maintenance of deer ...
Giving tigers the ability to mate with a larger selection of individuals will increase the gene pool for the tigers, which will lead to more diversity, higher birth rates, and higher cub survival. Panthera is a conservation organization that’s the main goal is to preserve wild cats focusing on tigers, lions, snow leopards, and jaguars. [53]
Habitat loss is one of the biggest threats to wild tiger populations. Using satellite images, researchers have created a new real-time mapping system for tiger habitats that could aid in ...
Although precipitation is not a limiting factor, the ground freezes during the winter months and plant roots are unable to absorb water, so desiccation can be a severe problem in late winter for evergreens. Although the taiga is dominated by coniferous forests, some broadleaf trees also occur, including birch, aspen, willow, and rowan.

These factors may include descriptions of the organism's life history, habitat, trophic position (place in the food chain), and geographic range. According to the competitive exclusion principle , no two species can occupy the same niche in the same environment for a long time.
