WILMHOFF, C.D.*; PETREN, K.; Univ. of Cincinnati; Univ. of Cincinnati: Behavioral mechanisms underlying competitive displacment in a gecko community Understanding the factors governing the distribution and abundance of organisms is a central goal of ecology. There is a wealth of information indicating that competition is an important factor in shaping distribution and abundance, but few […]

KROCHMAL, A.R.*; BAKKEN, G.S.; LADUC, T.J.; Indiana State University; Indiana State University; University of Texas, Austin: The role of facial pits in pitviper thermoregulation: behavioral and phylogenetic perspectives Pitvipers (Viperidae: Crotalinae) possess unique organs, the facial pits, which allow them to detect subtle temperature fluctuations within their environments. It was previously thought that these organs […]

By investigating how the size […]

LEE, DN; TANG-MARTINEZ, Z; Univ of Missouri, St. Louis; Univ of Missouri, St. Louis: The effects of early social environment on the exploratory behavior of prairie voles: Evaluation of methodologies In this study, I examined the effects of pre-weaning social environment on exploratory behavior of prairie voles, Microtus ochrogaster . I predicted that individuals that […]

BUCKLEY, Christine R.; MICHAEL, Scott F.; IRSCHICK, Duncan J.; Tulane University; Tulane University; Tulane University: The effect of hatching timing and substrate type on performance and behavior of a direct-developing frog The timing of hatching can have profound consequences for juvenile fitness in ectotherms. Potentially fatal threats may create a tradeoff between hatching early to […]

A.; Univ. of Western Ontario; Queen’s Univ.; Univ. of Western Ontario: Song Repertoire Size and Immunosuppression in Song Sparrows In many species of songbirds, song repertoire size has been found to be an important determinant of mate choice. Lab studies using song sparrows have demonstrated a female […]

MIKHEYEV, AS; University of Texas at Austin: Patterns of herbivory in leaf-cutting ants (Atta cephalotes) Leaf cutting ants are dominant herbivores of neotropical forests harvesting 12-17% of the leaves around their nests and possessing remarkable dietary breadth. In contrast with other studies, which assumed that leaf cutter foraging is guided by interspecific vairability in plant […]
