MCMILLAN, D.M.*; VANHOOYDONCK, B.; HERREL, A.; MEYERS, J.J.; IRSCHICK, D.I.; Tulane Univetsity; University of Antwerp ; University of Antwerp ; Northern Arizona University; Tulane University: Does the context of honest signaling change across populations? The idea that sexual signals should be honest signals of an animals intrinsic performance capacities is well established in behavioral ecology, […]

SULLIVAN, Laura E.*; COCROFT, Reginald B.; University of Missouri-Columbia; University of Missouri-Columbia: The influence of population density on mate-finding tactics and the strength of sexual selection in Enchenopa binotata treehoppers (Hemiptera: Membracidae) Within species, mating systems and the strength of sexual selection will vary in time and space depending on variation in resource distribution, population […]

BAEZA, J.A.; The University of Lousiana at Lafayette: The evolution of protandric-simultaneous hermaphroditism in the shrimp Lysmata wurdemanni is a consequence of sex-dependent time commitments but not sex-dependent mortality rates. Protandric simultaneous hermaphroditism (PSH), as recently reported for shrimps in the genus Lysmata, is a novel sexual system in which individuals invariably reproduce as males […]

HUSAK, Jerry F.*; LOVERN, Matthew B.; Virginia Tech; Oklahoma State University: Sexual selection on whole-animal performance: lizard locomotion and mating success Studies of sexual selection have focused mainly on morphological and behavioral traits, whereas studies of the evolution of physiological and morphological traits have focused on selection acting on whole-animal performance. Most of these studies […]

BIERBOWER, SM*; SPARKES, TC; DePaul University; DePaul University: Parasite-mediated sexual selection in an intermediate host, Caecidotea intermedius (Isopoda): effects of sperm production and male-male competition The acanthocephalan parasite Acanthocephalus dirus infects the aquatic isopod Caecidotea intermedius (intermediate host) and one of several freshwater fishes (e.g., sunfish) as a definitive host. Inside C. intermedius, the parasite […]

Meeting Abstract 36.1  Jan. 5  Ubiquity of many-to-one mapping in functional traits: examples and evolutionary implications ALFARO, ME*; COLLAR, DC; WAINWRIGHT, PC; Washington State University; University of California, Davis; University of California, Davis alfaro@wsu.edu Many functional traits can be decomposed into the emergent functional property and its underlying parts. For example, maximum bite force is determined by […]

Meeting Abstract 36.3  Jan. 5  Structure and function of hind limb feathers in Archaeopteryx lithographica LONGRICH, Nicholas; University of Calgary longrich@ucalgary.ca A restudy of the Berlin Archaeopteryx was undertaken to understand the morphology and function of the hind limb feathers. Feathers cover the legs of the Berlin specimen, extending from the cranial margin of the tibia and […]
