TAYLOR, E.N.*; MALAWY, M.; DENARDO, D.F; Arizona State University; Arizona State University; Arizona State University: Effects of food supplementation on the reproductive ecology of female Western Diamond-backed Rattlesnakes (Crotalus atrox) The physiological processes of desert reptiles may be limited by the availability of food. For example, food availability may influence growth and reproductive output. We […]

LEVIN, R.N.*; FREUND, K.; FUXJAGER, M.; Pomona College, Claremont, CA: Understanding Patterns of Variation in Avian Life History Traits: Comparisons of Temperate & Tropical House Wrens Food availability, nest predation and adult mortality are three factors commonly proposed to explain latitudinal and altitudinal variation in avian life history traits. We report here on our ongoing […]

LAPLANTE, L.H.; University of Connecticut: Social environment influences a nuptial signal displayed by female Halichoeres margaritaceus, the Pink-belly Wrasse In conventional mating systems, females are �choosy� and not expected to have elaborate mating displays; nonetheless female nuptial signals (FNS) are observed in a wide variety of taxa. Factors leading to the evolution of FNS have […]

KIM, TW; RISSANEN, R; REBEIRO, P; CHRISTY, JH; CHOE, JC; Seoul National University; University of Panama; Universidad Nacional de Mar del Plata; Smithsonian Tropical Research Institute; Seoul National University : Sexual differences in the affects of supplimental food on the semilunar reproductive rhythms of an intertidal crab Fiddler crabs and many other intertidal animals have […]

CARSTEN, LD; PAPAJ, DR; University of Arizona; University of Arizona: Sexual conflict and dynamic mating decisions in walnut flies (Rhagoletis juglandis) Conflict can arise between mating partners over reproductive decisions such as length and frequency of copulation. The mating decisions of both sexes can be influenced by context and state dependent factors such as social […]

KNAPP, R.*; NEFF, B.D.; Univ. Oklahoma, Norman; Univ. Western Ontario, London, Canada: Sex steroids and cortisol in male bluegill sunfish: Correlations with reproductive tactic and stage of parental care Across vertebrates, androgens and glucocorticoids influence behavior and mediate responses to environmental stimuli, especially with respect to reproductive behavior and function. We are investigating how these […]

PETERSEN, C.W.; SALINAS, S.*; KIDDER, G.W. III; PRESTON, R.L.; College of the Atlantic, Bar Harbor, ME; College of the Atlantic, Bar Harbor, ME; Mount Desert Island Biological Laboratory, Salisbury Cove, ME; Illinois State University, Normal: Reproductive ecology of Fundulus heteroclitus in a New England salt marsh The mummichog, Fundulus heteroclitus, is a widely distributed fish […]

WATERMAN, J.M.*; HILLEGASS, M.A.; University of Central Florida, Orlando; University of Central Florida, Orlando: Parasite removal and its impact on behavior and reproduction in a social African ground squirrel. In the social species of ground-dwelling sciurids, females live in cohesive, matrilineal social groups. There are many suggested benefits of such cohesive groups, yet in some […]

MENDON�A, MT; SCHMAEMAN, CN; GRILLIOT, ME; Auburn University, Auburn, AL: Mechanisms for sex recognition in the big brown bat: potential use of pheromones and ultrasonic vocalizations A variety of studies in bats have demonstrated the use of pheromones for mother-young recognition, roost mate recognition, and male-male recognition in harem systems. Additionally, the use of ultrasonic […]

FALLAHPOUR, K.; ESPINOZA, R.E.; California State University, Northridge; California State University, Northridge: Love sees no color: Indiscriminate courtship in male leopard lizards Visual signals are important components of social behavior and have important fitness consequences in many animals. Coloration is a common type of visual signal used by many lizards, particularly during courtship. Although less […]
