Do Predator Cues Influence Turn Alternation Behavior In Terrestrial Isopods Porcellio Laevis Latreille And Armadillidium Vulgare Latreille?, Scott L. Kight Oct 2014

Do Predator Cues Influence Turn Alternation Behavior In Terrestrial Isopods Porcellio Laevis Latreille And Armadillidium Vulgare Latreille?, Scott L. Kight

Department of Biology Faculty Scholarship and Creative Works

Terrestrial isopods (Crustacea: Oniscidea) make more alternating maze turns in response to negative stimuli, a navigational behavior that corrects divergence from a straight line. The present study investigates this behavioral pattern in two species, Porcellio laevis Latreille and Armadillidium vulgare Latreille, in response to short-term vs. long-term exposure to indirect cues from predatory ants. Neither isopod species increased the number of alternating turns in response to short-term indirect exposure to ants, but both species made significantly more alternating turns following continuous indirect exposure to ants for a period of one-week. These results are surprising given differences in behavioral and morphological ...
