Biology 6C 107 Exercise 5A Behavioral Ecology Adapted from General Ecology Labs , Dr. Chris Brown, Tennessee Technological University Introduction Physiological and behavioral ecologists study the ecology of individuals. An important question in both disciplines concerns ways in which organisms respond to abiotic factors in their environment. Today in lab we will study the influence of several abiotic factors on the behavior of terrestrial isopods, also known as pillbugs, woodlice, and roly-polys. Terrestrial isopods are crustaceans, a group of arthropods (like insects or spiders) which also contains crabs, lobsters and shrimps. Many species of isopods exist, and they occur in most regions of the world. Terrestrial isopods can often be found in large numbers by turning over stones or logs. Most species are omnivorous, feeding on decaying plant or animal matter. They often possess repugnatorial glands that emit a noxious chemical that acts as a predator deterrent. Some, such as Armadillidium spp., can also roll themselves tightly into a ball when disturbed (and thus have the common name roly-poly). Other species, such as the common sowbug
