even for amphibians.

Fertile biology of development of vertebrates (amphibians)

80 percent of all amphibians are threatened and in come decline.

We are losing species from the Earth faster than the dinosaurs disappeared, and leading that loss are amphibians.

In part, amphibians are good indicators and more sensitive because they don't have protection from contaminants in the water no eggshells, no membranes and no placenta.

In fact, my involvement in the whole pesticide issue was sort of a surprise as well when I was approached by the largest chemical company in the world and they asked me if I would evaluate how atrazine affected amphibians, or my frogs.

It's not just my work in amphibians, but similar work has been shown in fish in Europe, holes in the testes and absence of sperm in reptiles in a group from South America and in rats, an absence of sperm in the testicular tubules as well.

It is also a crisis of emerging infectious diseases (EID s), such as HIV in humans, Ebola in humans and gorillas, West Nile virus and Avian Influenza in humans and birds, chytrid fungi in amphibians, and distemper in sea lions. There is every reason to take these events seriously, because EID s appear to have a long evolutionary history.
