Beverly AjieB.S., Biology, Minor in Biological Anthropology. University
of Oregon. 2001. 1) Patterns of functional and genetic integration between induced behavioral
and morphological anti-predator defenses.
The
key player in the freshwater system that I use to investigate these issues
is the pulmonate snail, Physa sp. Physids are small (up to 15mm) herbivorous
and detritivorous snails. They are an important component of aquatic food
webs in streams, lakes and ponds worldwide. These snails are ideal for
ecological evolutionary studies due to their small size, fast generation
time and high fecundity.
