f their former range, and are increasing. There is also a new method that scientists are trying to use for the conservation of endangered animals. Sperm freezing, artificial insemination and embryo transfer are routine methods in several domestic species and applications of these techniques may also be used in wild species. However, reproduction physiology is very specific and before any technique can successfully be applied, the main reproduction features must be examined in target species or at least in a nearby relative species. In conclusion, for the species crisis to be addressed effectively, far greater action is needed. These issues are being tackled slowly, but hopefully the human race will realize how important wildlife really is, and start supporting the endangered species. ...
