BAYNE, CJ; BENDER, RC; BRODERICK, EJ; GOODALL, CP; Oregon State University; Oregon State University; Oregon State University; Oregon State University: A genetic basis for resistance to Schistosoma mansoni in Biomphalaria glabrata. Parasites normally elicit different degrees of pathology among members of a host population, due in part to host genetic polymorphisms. In the Schistosoma mansoni-Biomphalaria […]

CASE, J.E.*; MARSHALL, C.D.; Texas A&M University @ Galveston; Texas A&M University @ Galveston: Using Morphology to Predict Feeding Behavior: A Preliminary Study of Juvenile Red Snapper (Lutjanus campechanus) Feeding Red snapper are an important commercial species in the Gulf of Mexico. However, their biology and feeding mechanics are virtually unknown. The goals of this […]

VAN WASSENBERGH, S*; HERREL, A; ADRIAENS, D; AERTS, P; University of Antwerp; University of Antwerp; Ghent University; University of Antwerp: Terrestrial feeding in the eel catfish, Channallabes apus The air-breathing catfish Channallabes apus lives in the muddy swamps of tropical Africa. Stomach contents revealed that this species selectively feeds on (mostly terrestrial) Coleoptera. Although it […]

DAY, S W*; HIGHAM, T E; WAINWRIGHT, P C; Rochester Institute of Technology; Univ. of California, Davis; Univ. of California, Davis: THE RELATION OF SUCTION PRESSURE AND FLUID SPEED DURING FEEDING IN LARGEMOUTH BASS The suction feeding fish simultaneously generates negative pressure within the mouth and a flow field external to its head that draws […]

FRANCIS, A.W.; Villanova University, PA: Phylogeny and Feeding Biomechanics of Pleuronectiform Fishes Mechanical advantage of lower jaw depression and elevation was determined for five families and 10 genera of pleuronectiform fishes. Of the 11 species examined, five were sinistral and six dextral. Mechanical advantage for both lower jaw depression and elevation was lowest for species […]

MARKEY, M. J.*; MAIN, R. P.; MARSHALL, C. R.; Harvard University; Harvard University; Harvard University: In vivo cranial suture function and suture morphology in the extant fish Polypterus This study describes the mechanical role cranial sutures play in fish during feeding, and presents a quantification of fish suture morphology using microCT scanning. To measure suture […]

RICE, Aaron N.; University of Chicago and Field Museum of Natural History: Evolution of Coordination in Fish Feeding: The Intersection of Functional Morphology and Ecology Prey capture in fishes is a complex behavioral process. From initial sensory detection of a food item, to the final motor output of jaws and fins, these components have to […]

Meeting Abstract 63.5  Jan. 7  The effect of fertilization distance on the relationship between sperm production and male reproductive success in a colonial marine invertebrate JOHNSON, S.L.*; YUND, P.O.; University of Maine; University of New England sherij@maine.edu The shape of the function that describes the relationship between resources allocated to sperm production and resulting male fertilization success […]

Meeting Abstract 63.2  Jan. 7  The dwarf males of Osedax (Siboglinidae, Annelida). ROUSE, G.W.*; WORSAAE, K.; GOFFREDI, S.K.; VRIJENHOEK, R.C.; Scripps Institution of Oceanography; Zoological Museum, Copenhagen; California Institute of Technology; Monterey Bay Aquarium and Research Institute grouse@ucsd.edu All Osedax spp. discovered to date in Monterey canyon show marked sexual dimorphism, unlike all other siboglinids. Osedax males […]

Meeting Abstract 63.6  Jan. 7  Resource allocation to testes in the walnut fly, Rhagoletis juglandis CARSTEN-CONNER, L.D.*; O’BRIEN, D.M.; University of Arizona; University of Alaska, Fairbanks carsten@email.arizona.edu Testes size often predicts whether a male will win during episodes of sperm competition. However, little is known about the source of nutrients allocated to testes development. Among holometabolous insects, […]
