Meeting Abstract S7-1.2  Saturday, Jan. 5  The role of spatial and ontogenetic morphological variability in the spread of a tropical alga across barrier reefs and oceanic islands STEWART, H.L.; Friday Harbor Labs, University of Washington hstewart@u.washington.edu Hydrodynamic conditions on barrier reef systems range from wave-driven flow on the forereef to slow unidirectional flow in protected lagoons. This […]

Meeting Abstract S7-1.3  Saturday, Jan. 5  Swimming dynamics of squids throughout ontogeny BARTOL, I.K.; Old Dominion University, Norfolk, VA ibartol@odu.edu Squids encounter vastly different flow regimes throughout ontogeny as they undergo critical morphological changes to their two locomotive systems: the fins and jet. Squid hatchlings (paralarvae) operate at low and intermediate Reynolds numbers (Re) and typically have […]

Meeting Abstract S7-1.1  Saturday, Jan. 5   Size-dependent mode choices in aquatic locomotion VOGEL, Steven; Duke University svogel@duke.edu All active fliers get about in a similar fashion, with oscillating wings; but aquatic locomotion, less constrained by gravity, offers a complex set of choices. Should swimming be done on the surface or submerged? If on the surface, should […]

Meeting Abstract S7-1.5  Saturday, Jan. 5  Predictability of morphological differentiation across flow regimes in fishes LANGERHANS, Brian; Harvard University langerhans@oeb.harvard.edu Fish inhabit environments greatly varying in the intensities of water velocities experienced, and flow regime is generally believed to be of major evolutionary significance. While a sizeable volume of research has examined morphological variation across flow gradients […]

Meeting Abstract S7-1.4  Saturday, Jan. 5  Morphological Selection in a Distinctive Flow Environment: Body Shape and Waterfall-climbing Success in Hawaiian Stream Fishes BLOB, R.W.**; SCHOENFUSS, H.L.; MAIE, T.; CEDIEL, R.A.; PTACEK, M.B.; BRIDGES, W.C.; Clemson Univ.; St. Cloud State Univ.; Clemson Univ.; St. Cloud State Univ.; Clemson Univ.; Clemson Univ. rblob@clemson.edu Many fish species living in streams […]

Meeting Abstract S7-1.7  Saturday, Jan. 5  Hydrodynamic flow control in marine mammals FISH, F.E.*; HOWLE, L.E.; MURRAY, M.M.; West Chester University; Duke University; United States Naval Academy ffish@wcupa.edu The ability to control the flow of water around the body dictates the performance of marine mammals in the aquatic environment. Morphological specializations of marine mammals afford mechanisms for […]

Meeting Abstract S7-1.6  Saturday, Jan. 5  Ecomorphological variation in shell shape of the freshwater turtle Pseudemys concinna across different aquatic flow regimes RIVERA, G.; Clemson Univ grivera@clemson.edu Species with populations that inhabit a wide range of environments frequently display morphological variations that correlate with differences in environmental parameters. Flow velocity is a critical feature of aquatic environments […]

Meeting Abstract S6-2.3  Saturday, Jan. 5  Social Regulation of the Brain FERNALD, R.D.; Stanford University How does behavior change the brain? The long term objective our research program is to understand how social interactions produce specific changes in the brain. While it is common to study how the brain controls behavior, learning how the brain is influenced […]

Meeting Abstract S6-2.2  Saturday, Jan. 5  Musk Shrews: A Novel Model for Eating Disorders SCHNEIDER, Johanna S.; University of Virginia johanna.schneider@virginia.edu Concurrent with the rise in obesity has been the identification of binge eating disorder (BED). This disorder is characterized by repeated, intermittent overconsumption of food, but is distinguishable from bulimia in that food intake is not […]

Meeting Abstract S6-2.1  Saturday, Jan. 5  GnRH II A Multipurpose Peptide RISSMAN, Emilie F.; University of Virginia rissman@virginia.edu We have pioneered the use of the musk shrew (Suncus murinus) for studies of reproductive behavior. One of our novel findings is that this primitive placental mammal has at least two forms of gonadotropin releasing hormone (GnRH) in brain. […]
