Recently […]

Meeting Abstract 40.3  Wednesday, Jan. 5  Coevolution of morphology and locomotor performance in Urosaurus ornatus MILES, D B; Ohio University dmiles2@ohio.edu Species with widespread distributions often exhibit divergence in phenotypic traits. Such variation is attributed to selection imposed by local environmental conditions. Patterns in phenotypic traits that are associated with habitat or other ecological factors often are […]

Meeting Abstract 40.2  Thursday, Jan. 5  Predation ability in the wolf spider Hogna helluo STEFFENSON, M.M.*; FORMANOWICZ, D.R.; University of Texas at Arlington; University of Texas at Arlington mmsteff@uta.edu Spiders are classically used as an example of sexual size dimorphism among invertebrates. Theories postulated to explain the evolution of such gender differentiation include sexual selection for increased […]

Meeting Abstract 40.3  Thursday, Jan. 5  Evolutionary Co-option of Trap-jaw Ant Mandible Strikes: Defensive Interactions with Antlions LARABEE, F. J.*; SUAREZ, A. V.; Univ. of Illinois, Urbana-Champaign; Univ. of Illinois, Urbana-Champaign larabee@life.illinois.edu The co-option of existing traits for novel functions is fundamental to many theories of trait evolution, but few studies have examined evolutionary co-option at a […]

Meeting Abstract 40.4  Thursday, Jan. 5  Evading invaders: Adaptive significance of a behavioral response LANGKILDE, T*; FREIDENFELDS, N.A.; ROBBINS, T.R.; Penn State University; Penn State University; Penn State University tll30@psu.edu Understanding the mechanisms driving adaptations to survive agonistic interactions, and their function, provides insight into how native species respond to aggressive threats. The introduction of non-native species, […]

Meeting Abstract 40.4  Saturday, Jan. 5  Tubular heart pumping in tunicates and other invertebrates. BAIRD, A.J.*; MILLER, L.A.; Univ. of North Carolina, Chapel Hill ajbaird86@gmail.com Valveless tubular hearts transport hemolymph in many invertebrates with open circulatory systems. Tunicates such as Ciona intestinalis rely on bidirectional valveless pumping through a U-shaped heart tube. Research related to valveless fluid […]

Meeting Abstract 40.1  Saturday, Jan. 5  The intrinsic dynamical properties of muscle are self-stabilizing for rhythmic movements TYTELL, E.D.; Tufts Univ. eric.tytell@tufts.edu Animal locomotion is a rhythmic behavior that requires the effective coupling of multiple feedback loops, including mechanical coupling between the animal’s body and the environment, coupling between muscular force production and body movement, and sensory […]
