HUSAK, J. F.; LAPPIN, A. K.; Oklahoma State University; Northern Arizona University: A strong bite increases the mating success of collared lizards In territorial, polygynous taxa, individual variation in territory quality and mating success are expected to reflect individual variation in underlying morphological, physiological, and whole-animal performance traits. We studied a highly territorial, polygynous lizard […]

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 […]

Meeting Abstract 35.4  Jan. 5  Trophic enrichment without change in diet: An ontogenetic shift in &delta15N during insect metamorphosis TIBBETS, T. M.*; WHEELESS, L. A.; University of Wyoming ttibbets@uwyo.edu Analyses of nitrogen and carbon stable isotopes are widely used as tools in the study of food web structures and to estimate an animal�s trophic position. Most food […]

Meeting Abstract 35.1  Jan. 5  Regeneration in benthic ctenophores (Platyctenida) DUBUC, Timothy R; University of Hawaii Manoa dubuc@hawaii.edu Coeloplana and Vallicula species have a unique derived lifestyle compared to their pelagic relatives, including: a benthic habitat, loss of ctene rows, and a flattened oral/aboral body. Adult benthic ctenophores have a complex gastrovascular system laced with a rich […]

Meeting Abstract 35.5  Jan. 5  Peripheral nervous system development in the ascidian Ciona intestinalis ZELLER, Robert W.; San Diego State University rzeller@sciences.sdsu.edu Current hypotheses postulate that the ancestral bilaterian nervous originated as a basiepidermal nerve net that was interspersed with sensory neurons. During bilaterian evolution, this nerve net was independently centralized in both protostomes and in the […]
