Sediment Size and Interspecies Interaction affect Burrowing Times of Emerita talpoida in Swash
HORWITH, M.J.*; MERZ, R.A.; Swarthmore College; Swarthmore College: Sediment Size and Interspecies Interaction affect Burrowing Times of Emerita talpoida in Swash The mole crab Emerita talpoida inhabits Atlantic swash zones, where waves break and recede on sandy beaches. High water velocities and unpredictable flow patterns make swash zones challenging habitats for macroscopic animals. Mole crabs […]
Scaling of speed with body mass in terrestrial chelonians
GREGORY, M L*; CLAUSSEN, D L; Miami University; Miami University: Scaling of speed with body mass in terrestrial chelonians Although scaling can reveal some interesting correlates between body size and locomotor performance, only a few turtle species have heretofore been examined. We recorded maximal speeds of 17 species of adult terrestrial chelonians (N=77) and evaluated […]
Scaling of chewing frequency in primates
WASHINGTON, RL*; ECKHARDT, A; ROSS, CF; University of Chicago; University of Chicago; University of Chicago: Scaling of chewing frequency in primates In mammals, significant food processing occurs in the oral cavity prior to swallowing, so ingestion rate is related to the rate of oral food processing. It therefore seems likely that chewing frequency is an […]
SEROTONERGIC CIRCUITRY IN THE NERVOUS SYSTEM OF A BIVALVE VELIGER LARVA
KEMPF, S.C.; Auburn University: SEROTONERGIC CIRCUITRY IN THE NERVOUS SYSTEM OF A BIVALVE VELIGER LARVA While a considerable amount of research has focused on the larval shell, larval feeding, assays of neuroactive compounds, etc. of bivalve veligers, there is surprisingly little work on the structure of the larval nervous system and the circuitry responsible for […]
Reproductive suppression in female Cape ground squirrels, Xerus inauris
PETTITT, Beth*; WATERMAN, Jane M; University of Central Florida; University of Central Florida: Reproductive suppression in female Cape ground squirrels, Xerus inauris Cooperative breeding is common among social animals and is characterized by group members that exhibit delayed dispersal from natal group, reproductive suppression, and alloparental care. Mechanisms of reproductive suppression may be mediated through […]

Relative hippocampal volume is affected by age in migratory Mountain White-Crowned Sparrows
SANFORD, K.H.*; BREUNER, C.W.; HAHN, T.P.; PRAVOSUDOV, V.V.; Univ. of California, Davis; Univ. of Texas, Austin; Univ. of California, Davis; Univ. of Reno: Relative hippocampal volume is affected by age in migratory Mountain White-Crowned Sparrows The hippocampus (HF) is necessary for the formation of spatial memories. Migratory birds rely on spatial memory as part of […]

Pulsed jet dynamics of squid during ontogeny
BARTOL, I.K.*; STEWART, W.J.; Old Dominion University; Old Dominion University: Pulsed jet dynamics of squid during ontogeny Pulsed jetting is used by squids of remarkably different sizes, from hatchlings that are only a few millimeters in length to adults that may grow as large as 18 meters. Over this wide size range, the physics of […]
