1. Species which travel distances between important areas for their survival, such as breeding and feeding areas may be particularly vulnerable to habitat destruction. How might the creation of multiple national parks or nature reserves help such species?
2. How could separation of breeding periods in frogs result in niche differentiation in the tadpoles?
plz help fast thx

Have Environmentalists Ever Considered Helping An Endangered Species By Introducing It To Replace An Extinct..?
Posted on 04 November 2011.
Species. Let me explain.
For example, the Guam Rail is extinct in the wild because of the Brown Tree Snake. Meanwhile, the Hawaiian, Laysan and Wake Island Rails are all extinct, for different reasons. Could introducing the Guam Rail to one of these islands work? The Wake Island rail was extirminated by hungry soldiers in WWII, and the Laysan Rail was victim of habitat destruction by rabbits, but the rabbits have been exterminated, so the Guam Rail would not be threatened by those.
So, the Guam Rail ‘could’ be helped by filling an ecological niche, thereby probably helping (or at least not hurting) the island it’s introduced to. Of course, whether or not it survives is still a question, but research beforehand would probably fix/help that.
But, yeah- has there been any thought of helping an endangered species by having it ‘replace’ a similar extinct species to increase it’s numbers?
