Since the fall semester has finished I thought I would share a few interesting tid bits from my animal ecology class. Both inside and outside the classroom we dove into the amazing world of animals and how they interact in their respective terrestrial or aquatic environments.
Did you know?
Wood peckers have barbed tongues that wrap around their skulls.
Red squirrels are nest predators. They sometimes eat bird eggs.
Dragonfly larvae are aquatic until they metamorphose into an adult dragonflies. They are cannibalistic, as we found out in our predation experiments.
One way ecologists mark salamanders (for mark & recapture studies) is by trimming off one of the digits on the limbs of the larval salamanders. It is common for young salamanders to loose digits while fighting with other larvae. These studies are done to estimate population size.
