WARKENTIN, KM; CALDWELL, MS*; MCDANIEL, JG; Boston University; Boston University; Boston University: The feeling of danger: how red-eyed treefrog embryos use vibrational cues to assess risk Red-eyed treefrog embryos, Agalychnis callidryas develop in gelatinous egg clutches on vegetation over ponds, where they are preyed on by snakes. If attacked, embryos can hatch up to 30% […]

WUND, M. A.; University of Michigan: The Development of Plastic Echolocation in the Little Brown Bat, Myotis lucifugus Recently, much research has focused on the evolution and development of plastic traits. Behaviors are unique traits in that they may rapidly change via learning. Thus, behavioral plasticity may develop and evolve in ways other plastic traits […]

BURMEISTER, S.S.; JARVIS, E.D.; FERNALD, R.D.; Stanford University; Duke University; Stanford University: Rapid Response of the Preoptic Area to Social Opportunity Social interactions regulate many aspects of behavior and physiology. In the cichlid fish, Haplochromis burtoni, social dynamics among males determine whether an individual male becomes territorial or non-territorial, two phenotypes that differ in body […]

HRISTOV, N.I.*; CONNER, W.E.; Wake Forest University, Winston-Salem, North Carolina; Wake Forest University, Winston-Salem, North Carolina: Predator-Prey Interactions: A 3D-Analysis of the Bat-Moth Arms Race The acoustic interaction between insectivorous bats and tiger moths (Lepidoptera: Arctiidae), has puzzled behavioral biologists for over three decades. When approached by hunting bats, tiger moths answer with a series […]

WOLF, Mary C; QUINN, Eric; MARTIN, Art; ZULANDT, Thomas; MOORE, Paul A.; Bowling Green State University; University of Cincinnati; Bowling Green State University ; Bowling Green State University ; Bowling Green State University : Odor plume distribution in a natural stream system A natural stream environment is made up of different types of habitats that […]

BOURDEAU, P.E.*; PADILLA, D.K.*; Stony Brook University; Stony Brook University: �Might as well jump� � Inducible dispersal in response to environmental cues in two species of Littorine snails For many organisms, the ability to assess and respond to cues from the surrounding environment has important fitness consequences. In particular, the ability to disperse from a […]

HOCHMAN, Valeria; KOTLER, Burt; Ben Gurion University of the Negev; Ben Gurion University of the Negev: Measuring foraging behavior of Nubian Ibex under predation risk For Nubian ibex (““Capra nubiana”“) cliffs provide refuge from predators, but may not provide foraging opportunities. Therefore it is expected that for ibex seeking food away on plateaus away from […]

WATERMAN, JM; Univ. of Central Florida, Orlando: Environmental influences on the social system of the Cape ground squirrel, Xerus inauris Characterizing the ecological constraints that influence the structure of social groups is a major task in the study of sociality. In many species, as environmental conditions become more severe or the habitat becomes saturated, the […]

MORETZ, J.A.; MORRIS, M.R.; Ohio University; Ohio University: A comparative analysis of the role of aggression in the evolution of vertical bars in northern swordtail fishes Males of many swordtail species possess vertical bars, a pigment pattern that is found throughout the Xiphophorus genus and other poeciliid fishes. Males use these bars in both courtship […]

KENNEDY, M.S.; SPENCER, R-J.; BAXTER, G.S.; Univ. of Queensland, Gatton, Australia; Iowa State Univ.; Univ. of Queensland, Gatton, Australia: Using small mammals to test ecological processes driving population and community processes after fire in a nutrient poor environment. Patterns of small mammal community responses to fire events are well documented in some regions of Australia. […]
