LONDRAVILLE, R.L.*; NIEWIAROWSKI, P.H.; MCCONNELL, D.A.; ORCUTT, F.S.: Cooperative Learning in Large Undergraduate Science Classes. Cooperative learning exercises were incorporated into large (~100 student) sections of introductory undergraduate classes in Biology and Geology. ‘Lecture’ was reduced by more than half, with most of the class dedicated to working in cooperative groups. A variety of classroom […]

Comparison of Takeoff Kinematics in Gliding and Nongliding Squirrels
ESSNER, R.L.: Comparison of Takeoff Kinematics in Gliding and Nongliding Squirrels Precise descriptions of behavior are key to understanding the role of morphology in the evolution of novel locomotor modes. While a number of studies have compared morphological variation among gliding and nongliding forms, there is currently a lack of insight into the extent of […]
Chemically stimulated deposit-feeding in the spionid polychaete, Polydora quadrilobata
RIORDAN, T.J.*; LINDSAY, S.M.: Chemically stimulated deposit-feeding in the spionid polychaete, Polydora quadrilobata In marine soft-sediment habitats, chemical sensing by deposit feeding organisms most likely plays a critical role in feeding behavior, yet few specifics about this role and its ecological implications are known. As part of a multi-disciplinary investigation of chemoreception in the spionid […]
Buccal oscillation in the aquatic turtle Platysternon megacephalum
DRUZISKY, K.*; BRAINERD, E.L.: Buccal oscillation in the aquatic turtle Platysternon megacephalum Buccal oscillation has been demonstrated in all major groups of vertebrates except mammals (Brainerd, 1999). Using blowhole pneumotachography and video, we examined above-water buccal oscillations in an aquatic turtle, Platysternon megacephalum. In this study, we were able to distinguish between oscillation and ventilation […]
Bringing Active Science to Classroom and Community with Antarctic Chemical Ecology Research
Hubbard, J.M.: Bringing Active Science to Classroom and Community with Antarctic Chemical Ecology Research Few students, teachers or members of the general public participate directly in cutting-edge research and therefore fail to develop a full understanding of scientific issues. A community of teachers and researchers, supported by the National Science Foundation, have created the Teachers […]
Brain Atlas of the Sheep on the Internet for Courses in Neurobiology
JOHNSON,J.I.*; SUDHEIMER,K.D.; DAVIS,K.K.; WINN,B.M.: Brain Atlas of the Sheep on the Internet for Courses in Neurobiology Brain specimens of sheep are convenient for classroom instruction in neurobiology. As an adjunct to use of these specimens, we have prepared a histologically detailed and labeled atlas of external features and internal architecture of the sheep brain, at […]
Biomechanics of quadrupedal walking How do four-legged animals walk like inverted pendulums
MAIN, R. P.*; GRIFFIN, T. M.; FARLEY, C.T.: Biomechanics of quadrupedal walking: How do four-legged animals walk like inverted pendulums? Walking bipedal and quadrupedal animals conserve mechanical energy by converting kinetic energy into gravitational potential energy and vice-versa. This inverted pendulum-like exchange is well understood for bipeds in which the center of mass (COM) vaults […]
Attraction of Conspecifics to Molt Signals in Crayfish
ADAMS, J.A.*; MOORE, P.A.: Attraction of Conspecifics to Molt Signals in Crayfish For many organisms olfaction plays a key role in communication. Crayfish use olfactory signals to find mates, warn of predators, and relay social status. While many of these situations have been studied in detail, behavior of conspecifics toward molted individuals has not. The […]
Attraction To Maternal Odor By Juvenile Crayfish, Orconectes rusticus
Kari L. Long*; Paul A. Moore: Attraction To Maternal Odor By Juvenile Crayfish, Orconectes rusticus Chemical odor cues have been found to play an important role in the behavior and ecology of several species of juvenile organisms, including crayfish. In crayfish, cannibalism occurs among juveniles of different broods, therefore chemical signals that can convey maternal […]
Assessing the Weight that Black Widow Gumfoot Lines Can Pick Up
LOPEZ, Y.; MOORE, A.M.F.: Assessing the Weight that Black Widow Gumfoot Lines Can Pick Up Like other theridiid spiders, the black widow (Latrodectus hesperus) constructs gumfoot lines at the bottom of its cobweb. Gumfoot lines are vertical strands of silk that are tautly attached to the surface and detach easily when an insect touches them. […]
