A low level of one factor can sometimes be partially compensated for by appropriate levels of other factors. In case of chemical reactions it is known as law of limiting factor. A corollary to this is that two factors may work synergistically (e.g. 1 + 1 = 5), to make a habitat favorable or unfavorable. Geographic distribution of sugar maple.
A captive white tiger in Birmingham, United Kingdom A captive white tiger in Yerevan Zoo, Armenia. Because of the extreme rarity of the white tiger allele in the wild, [10] the breeding pool was limited to the small number of white tigers in captivity. According to Kailash Sankhala, the last white tiger ever seen in the wild was shot in 1958.
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]
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 ...
In most cases combinations of factors are responsible for limiting the geographic range edge of species. Abiotic and biotic factors may work together in determining the range of a species. An example might be some obligate seeder plants where the distribution is limited by the presence of wildfires, which are needed to allow their seed bank to ...
The decline of wild mammal populations globally has been an occurrence spanning over the past 50,000 years, at the same time as the populations of humans and livestock have increased. Nowadays, the total biomass of wild mammals on land is believed to be seven times lower than its prehistoric values, while the biomass of marine mammals had ...
Like human-predator in Africa, encounters between tigers, people, and their livestock is a prominent issue on the Asian continent. Attacks on humans and livestock have exacerbated major threats to tiger conservation such as mortality, removal of individuals from the wild, and negative perceptions of the animals from locals. [19]
The white tiger has a white background colour with sepia-brown stripes. The golden tiger is pale golden with reddish-brown stripes. The snow-white tiger is a morph with extremely faint stripes and a pale sepia-brown ringed tail. White and golden morphs are the result of an autosomal recessive trait with a white locus and a wideband locus ...
