DEVAERE, S; JANSEN, G; ADRIAENS, D*; WEEKERS, PHH; Ghent University, Belgium; University of Helsinki, Finland; Ghent University, Belgium; Ghent University, Belgium: Clariid catfish: an extreme case of convergent evolution on a low taxonomical level Clariids represent an impressive range between fusiform and anguilliform morphs. Although this has been observed in other families of teleosts or […]

RANOLA, J.O.**; TOBALSKE, B.W.; WARRICK, D.R.; POWERS, D.R.; Univ. of Portland; Univ. of Portland; Oregon State Univ.; George Fox Univ.: Circulation in the Wake of the Flying Hummingbird: Effects of Thresholding and Vortex Decay Recent physical modeling has shown that measures of circulation in the wake of flying animals may underestimate bound circulation on their […]

NAMWONG, W.*; WITHYACHUMNARNKUL, B.; CHANG, S.A.; CHANG, E.S.; Mahidol Univ., Bangkok, Thailand; Mahidol Univ., Bangkok, Thailand; Bodega Marine Laboratory, Univ. of California-Davis; Bodega Marine Laboratory, Univ. of California-Davis: Characterization of the Molt Cycle in Relation to Hemolymph Ecdysteroid Levels in the Ridgeback Shrimp (Sicyonia ingentis) Ridgeback shrimp (Sicyonia ingentis) are native to Southern California. In […]

KAVANAUGH, S.I.*; SOWER, S.A.; Univ. of New Hampshire: Characterization of gonadotropin-releasing hormone (GnRH) in the Atlantic hagfish Myxine glutinosa Hagfish are the oldest lineage of vertebrates with a lineage extending over 530 million years. They are in a key position between protochordates and vertebrates and they retain characteristics of extinct ancestral species that are common […]

HATLE, JD*; WELLS, SM; ALLEN, IC; FULLER, LE; MELNYK, S; QUATTROCHI , J; Univ. of North Florida: Calorie restriction enhances longevity without altering hemolymph protein or lipid storage in female grasshoppers Calorie restriction (CR), under eating while avoiding malnutrition, modifies life history tactics in many organisms. Specifically, CR enhances longevity by allocating to storage and […]

FREMONT, RT*; HALE, ME; Univ. of Chicago: Building Neural Networks: The Response of the Zebrafish Startle Circuit to Ectopic Expression of Mauthner Cells Brain evolution is thought to be constrained by the interconnectedness of neurons responsible for central nervous system function. Altering a subset of cells in a neural circuit may benefit one function but […]

LONG, J.A.*; HORTON, B.M.; Univ. of Maine, Orono; Univ. of Maine, Orono: Bringing Ornithology to K-12 Classrooms Education is vital to the success of bird conservation efforts. A National Science Foundation sponsored program at the University of Maine helps meet this need. This program places outstanding graduate students in local K-12 classrooms to enhance science […]

CLASS, A.M.*; CHAVES-CAMPOS, J.; Virginia Tech; Purdue University: Breeding behavior and nest site selection of the Ocellated Antbird Phaenostictus mcleannani Basic knowledge of the natural history of species is essential to our understanding of reproductive biology. Our understanding of tropical bird natural history is particularly poor. Tropical obligate ant-following birds track army ant colonies foraging […]

RIDGELY, RC*; WITMER, LM; Ohio University; Ohio University: Braincase morphology in tyrannosaurs using computed tomography and 3D visualization, with special reference to the cerebral endocast and ear region The morphology of the ear region, cerebral endocast, and pneumatic sinuses in the braincases of tyrannosaurid dinosaurs was investigated using CT and 3D visualization. Several adult specimens […]

GERRY, SP*; DEAN, MN; WILGA, CD; University of Rhode Island; University of California, Irvine; University of Rhode Island: Bilateral jaw muscle activity in elasmobranchs Asynchronous activation of bilateral jaw muscles permits a higher degree of motor control during feeding and food processing. Many previous studies on motor activity in elasmobranchs and bony fishes have implanted […]
