HATCH, K.A.; TRACY, C.R.; Brigham Young University; University of Nevada, Reno: Winterkill of Rana luteiventris in a riparian habitat Little research has been done on the biology of hibernating frogs in their natural habitat. Columbia spotted frogs (Rana luteiventris) are primarily aquatic and anecdotal evidence suggested that they dig into soft banks of streams or […]

VENN, C.*; LENIG, J.L.; Bloomsburg University of Pennsylvania; Bloomsburg University of Pennsylvania: Unique Pattern of Barnacle Settlement Associated with the 1997-1998 ENSO The TAO/TRITON buoy array in the tropical Pacific is a network of 77 moorings that are deployed to measure and relay environmental conditions between 8 degrees north and 8 degrees south of the […]

GOODALE, E.; Univ. of Massachusetts, Amherst: The attraction of mixed-species flocking birds to the vocalizations of other species Can playback be used to investigate the structure of a mixed-species bird flock community? I In this study, I played back the vocalizations of the two most frequent members of a large Sri Lankan flock system, the […]

KAPLAN, P.; University of Michigan: Testing the role of competition as a community organizer using limiting similarity Biotic interactions, such as competition, are the chief structurers of modern communities. A uniformitarian view would suggest the same for paleocommunities, but paleontologists have made little headway in demonstrating such a relationship through deep time. The main difficulty […]

HALPIN*, P. M.; MENGE, B. A.; HOFMANN, G. E.; Univ. of California, Santa Barbara; Oregon State Univ.; Univ. of California, Santa Barbara: Fine-scale temporal and spatial variation in the heat shock response of mussels in nature One of the potential effects of global climate change is the increase of thermal stresses on organisms. Ecologists and […]

KROCHMAL, A.R.*; BAKKEN, G.S.; Indiana State University; Indiana State University: The ecology and phylogenetic distribution of facial-pit mediated thermoregulatory behavior among rattlesnakes (Crotalus and Sistrurus Pitvipers (Viperidae: Crotalinae) possess unique organs, called facial pits, which allow them to detect subtle temperature fluctuations within their environments. It was previously thought that these organs were used solely […]

COWART,, J.D.; Univ. of Florida, Gainesville: The Mating System of a Pterasterid Sea Star: Hermaphroditism, Sperm Storage, or Parthenogenesis? The eggs of the sea star Pteraster tesselatus are capable of developing to the juvenile stage without artificial fertilization, without evidence of sperm in the water, and without the elevation of a vitelline envelope. I offer […]

WYETH, R.C.; WILLOWS, A.O.D.; University of Washington; University of Washington: Integration of multiple sensory cues by the nudibranch mollusk, Tritonia diomedea, during navigation through its natural habitat Animals use a variety of senses to navigate through their environment. How do they integrate multiple senses to direct movement? The nudibranch Tritonia diomedea is an excellent candidate […]

SANDERSON, C.E.; HILL, P.S.M.; WELLS, H.; University of Tulsa; University of Tulsa; University of Tulsa: Honey bee response to differences in handling time, rewards and flower colors Foraging behavior of honeybees (Apis mellifera) was studied in order to examine the interaction that differences in reward, flower handling-time, and flower color have on the decision process […]
