The Andean mountain cat is native to South America. Its distribution is restricted to thehighlands of the Andes, to central and southern Peru and northern Bolivia, Chile and Argentina.

 

We don’t know ih their are in danger because an human action or because of a natural action because they skin are very goods yes, but in the Andes the people think that kill a Andean mountain cat brings bad luck. And thera aren’t reports of traffic of their skin. And their food is very difficult to found and because of this we can think that there are a specific predator and this cause this little number of them.

Predation.

An example of predation is when a lion hunt a buffalo or antelope in the Savanna. The lion gets food from the preys but they don´t achieve anything from it.

Biogeography

Biogeography is the study of the distribution of species, it mix biology, geography and history, because it aims to reveal the place where they are, at what abundance and why they are and not in another place.

This dispersion of species is created by the evolution that make that one species can live in one place and anothers in other places. The evolution adapt species to live in one place or in other. This is the relationship between evolution and Biogeography.

Sorry to be late.
