CRESPI, E.J.*; VAUDRY, H.; DENVER, R.J.; Univ. of Michigan, Ann Arbor; Univ. of Rouen, France; Univ. of Michigan, Ann Arbor: Development of neuroendocrine controls of food intake in amphibians Almost all studies on the neuroendocrine controls of food intake have been conducted on juvenile or adult animals; thus, little is known about the roles of […]

GILL, S.A.*; ALFSON, E.D.; HAU, M.; Princeton University; Princeton University; Princeton University: The myth of the passive sex: hormonal control of female aggression in a year-round territorial bird The hormonal control of territorial aggression in female vertebrates is still unclear. We therefore studied buff-breasted wrens (Thryothorus leucotis), a resident of the neotropics, in which females […]

SCOTTI, M.L.*; DEMAS, G.E.; Indiana University, Center for the Integrative Study of Animal Behavior; Indiana University, Center for the Integrative Study of Animal Behavior: Seasonal aggression in female Siberian hamsters (Phodopus sungorus) Most seasonally breeding species demonstrate a suite of adaptations including reproductive regression and increased territorial aggression in short �winter-like� compared with long �summer-like� […]

JAWOR, Jodie*; RICHARDSON, Jennifer; KETTERSON, Ellen; Indiana University, Bloomington, IN; Indiana University, Bloomington, IN; Indiana University, Bloomington, IN: Do hormones other than testosterone influence intrasexual aggression in female dark-eyed juncos (Junco hyemalis)? Hormones and aggressive behavior have been widely studied in male birds, but not as widely in females. In some species, female aggression has […]

Meeting Abstract 5.2  Jan. 4  Moving away from the mean: does trophic divergence in sympatric populations of the Gold-breast Splitfin, (Ilyodon furcidens) increase fitness? HUIZINGA, M.*; GHALAMBOR, C.K.; Colorado State University Meribeth.Huizinga@colostate.edu A central focus of evolutionary ecology is to understand how historic and current processes interact to generate and maintain patterns of diversity within and between […]
