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 […]

OPHIR, A.G.*; PHELPS, S.M.; WOLFF, J.O.; Univ. of Florida; Univ. of Florida; Univ. of Memphis: Selection for social but not genetic monogamy in the prairie vole Perhaps best known for work relating to the study of mechanisms of pair bond formation, the prairie vole (Microtus ochrogaster) has emerged as a �poster child� of monogamous behavior […]

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 […]

KIM, Tae Won*; KIM, Tae Geun; CHOE, Jae Chun; Seoul National University; Seoul National University; Seoul National University: The evolution of courtship structure building in fiddler crabs: Has it evolved for predation avoidance in both sexes? In some species of fiddler crabs, pair formation is composed of male claw waving, female attraction to semidome-like structures […]

STEFFEN, J.E.*; SIEFFERMAN, L.; Auburn University: Spectral Properties of the dewlaps of Florida Brown Anoles, Norops sagrei Male and female Brown Anoles (Norops sagrei) possess a throat fan, or dewlap, that is purportedly used for communication between conspecifics in courtship and territorial interactions. To humans this dewlap appears red-yellow-orange on the lateral portion and yellow […]

SCORDATO, ES*; DREA, CM; Duke University; Duke University: Sex-specific variation in Ringtailed lemur Lemur catta olfactory communication Prosimians are unique among primates in their reliance on complex olfactory cues as a primary mode of social signaling. Scent marking may serve to demarcate territories, maintain dominance hierarchies, and advertise reproductive state. Male Lemur catta use species-specific […]

GEE, JM; Cornell University: IEG and Behavioral response to conspecific and heterospecific calls in hybridizing avian species, California and Gambel’s quail Divergence in characters that determine choice of mate, such as song, is central to the process of speciation in birds. Prior to complete speciation, preference for song may vary among individuals within a single […]
