Parasites might spur evolution of strange amphibian breeding habits
Date:11/14/2007

n amphibian populations in Central and South America, and researchers can examine the populations over time to see if species with non-traditional breeding habits are less affected. Scientists could also compare the burden of parasites on traditional and non-traditional breeders.

Of course, there are benefits to breeding in the water most importantly that there is plenty of food. But Todd said that when the death rate from parasites or any other aquatic threats exceeds the benefits that come with rapid growth, natural selection begins to favor strategies that shorten or eliminate the aquatic life cycle phase altogether.

The role of parasites has been overlooked until now, Todd said. I want to highlight the idea that they might be important to evolution so that people can begin studying amphibians in a new light.
