What is a Siberian white tigers Ecosystem?

The Siberian Tigers habitat is the Evergreen forests of Northern China and Southeastern Siberia. Mountain/snowy forest in china and Russia. Tigers are top predators, meaning that they kill other animals for food, and no other animals kill them. Tigers have no natural enemies (only humans hunt tigers) and they do it for their fur, their bones or just for kicks, not in order to eat them.


What contributes to natural selection?

Any environmental change contributes to natural selection. This could even result from competition within one's own species. Rising population modifies an environment, creating opportunities for natural selection. Changing climate exerts selective pressure on allspecies. There has been an evolutionary "arms race" between tigers and Gazelles. As the gazelles grew faster to escape the jaws of tigers, only the faster tigers would tend to eat well and pass on their genetic heritage.


Is the white tigers fur mutation dominant or benificial?

Well, the white tigers fur mutation isn't dominant nor beneficial (depends). The allele for white fur in tigers is recessive and even then not many tigers are heterozygous (One dominant allele and one recessive allele for those who do not know) Now it can be beneficial depending where the tigers live, there used to be Siberian Tigers who lived in the snow so it would be beneficial there but white fur will decrease stealth ability in the jungles, therefore alleles can be beneficial or harmful depending on the allele and where the organism lives.
