Meeting Abstract S12.11  Wednesday, Jan. 7 15:00  Integrating approaches to biomechanics: developmental phenogenomics of stickleback evolution JAMNICZKY, Heather A*; ROGERS, Sean M; University of Calgary, Canada; University of Calgary, Canada hajamnic@ucalgary.ca The tight fits between form and function in organisms suggests the influence of adaptive evolution in biomechanics; however, the prevalence of adaptive traits, the mechanisms by […]

Meeting Abstract S12.10  Wednesday, Jan. 7 14:30  Cypriniform suction feeding: Evolving in and out of the ooze HERNANDEZ, LP*; STAAB, KL; George Washington University; McDaniel College phernand@gwu.edu While much of the functional work on suction feeding has involved members of Acanthopterygii, a much older cypriniform radiation led to almost 4000 species filling nearly every freshwater trophic niche. […]

Meeting Abstract S12.6  Wednesday, Jan. 7 11:00  Copepod escape from suction feeding fish YEN, J.*; MURPHY, D.W.; WEBSTER, D.R.; Georgia Tech; Johns Hopkins ; Georgia Tech jeannette.yen@biology.gatech.edu http://www.biology.gatech.edu/faculty/jeannette-yen/ Copepods escape very well. As a key link in the aquatic food web, these small planktonic organisms often encounter suction feeding fish. Studies have identified certain hydrodynamic features that […]

Meeting Abstract S12.3  Wednesday, Jan. 7 09:00  Computational fluid dynamics of suction feeding VAN WASSENBERGH, S.; Ghent University, Belgium sam.vanwassenbergh@ugent.be http://https://www.uantwerpen.be/en/staff/sam-vanwassenbergh/my-website/ Suction feeders generate a flow of water that draws the prey into the mouth. This process involves extremely unsteady flow, outside as well as inside of the mouth cavity. Especially for flow patterns inside the mouth […]

Meeting Abstract S12.8  Wednesday, Jan. 7 13:30  Complexity and integration in biomechanics: Using prey capture in fishes to explore a novel approach for understanding organismal performance KANE, E. A.*; HIGHAM, T. E.; Colorado State University; University of California, Riverside emily.kane@colostate.edu http://emilyakane.blogspot.com Organisms comprise multiple interacting parts, and an increased number or specialization of those parts leads to […]

HANRAHAN, J.W.* *; ZHU, T.; DAHAN, D.; FUNG, S.; MEREDITH, J.; PHILLIPS, J.E.: The cystic fibrosis transmembrane conductance regulator (CFTR) chloride channel CFTR is a phosphorylation-regulated chloride channel and member of the ATP binding cassette (ABC) transporter superfamily of proteins. There have been no reports of CFTR homologues in invertebrate animals although ABC transporters are […]

Patrick, M.L.*; Bradley, T.J.: Salt-Lovin’ Skeeters: The Osmoconforming Strategy of Mosquito Larvae Culex is a genus of mosquito that possesses both freshwater restricted (e.g. C. quinquefasciatus) and euryhaline larvae (e.g. C. tarsalis), the latter being able to tolerate up to 70% full strength seawater. While held in freshwater conditions, both the euryhaline and the freshwater-restricted […]

HARRISON, J.F.: Renal and Respiratory Mechanisms of Acid-base Regulation in Grasshoppers In 1961, J.E. Phillips first provided data to support the hypothesis that active, regulated secretion of acid by the grasshopper hindgut functions as a pH regulatory mechanism. Subsequent studies by Phillips and co-workers, and our laboratory have strongly supported this hypothesis. First, it is […]

Clark, T.M.: Integrative Aspects of Epithelial Transport in Larval Aedes aegypti In contrast to the extensively studied hormonal regulation of Malpighian tubule function, regulation of midgut transport has been largely ignored. 5-hydroxytryptamine (5-HT; serotonin) is perhaps best known among insect transport physiologists as one of a suite of hormones regulating Malpighian tubule function. In larval […]

Lewis, S.A.: Extracellular Modulation of Epithelial Permeability One of the primary functions of an epithelium is to act as a barrier to the movement of substances between the lumen of the epithelium and the blood. Loss of epithelial barrier function due to cell death can lead to a loss of homeostasis and result in death […]
