Vortex perturbation of fish hovering
Meeting Abstract P3.62 Friday, Jan. 6 Vortex perturbation of fish hovering FLAMMANG, B.E.*; ALBEN, S.; LAUDER, G.V.; Harvard University; Georgia Institute of Technology; Harvard University bflammang@post.harvard.edu The pectoral fins of most fishes are flexible and deformable and their overall shape changes during a fin beat. While whole pectoral fins have been the subject of locomotor studies, there […]

Meeting Abstract P3.107 Friday, Jan. 6 Vertical distribution of Pisaster ochraceus larvae in haloclines after prior exposure to low salinity LEE, D.; GEORGE, S.B.*; Georgia Southern University; Georgia Southern University georges@georgiasouthern.edu An increase in the frequency and intensity of fresh water incursions into the Puget Sound could change the dynamics of rocky shore communities in the Pacific […]
Variation in Fast Start Performance of Bluegill Ecomorphs
Meeting Abstract P3.136 Friday, Jan. 6 Variation in Fast Start Performance of Bluegill Ecomorphs GERRY, S.P.*; ROBBINS, A.; ELLERBY, D.J.; Fairfield University; Wellesley College; Wellesley College sgerry@fairfield.edu Bluegill sunfish (Lepomis macrochirus) from Lake Waban, MA exhibit variation in their morphology and swimming performance based on habitat. Pelagic ecomorphs have a relatively streamlined, fusiform body shape that correlates […]
Uptake of dissolved high molecular weight molecules by larvae of Lytechinus variegatus
Meeting Abstract P3.116 Friday, Jan. 6 Uptake of dissolved high molecular weight molecules by larvae of Lytechinus variegatus MCDONALD, A.J.*; JAECKLE, W.B.; Illinois Wesleyan Univ., Bloomington; Illinois Wesleyan Univ., Bloomington amcdonal@iwu.edu Echinoid larvae can absorb small and large dissolved organic materials (DOM) from seawater (e.g., amino acids and proteins, respectively). DOM uptake is normally attributed to ectodermal […]
Unique mechanosensory adaptation to extreme environments in cavefish

UV and mate choice in the sailfin molly, Poecilia latipinna
Meeting Abstract P3.162 Friday, Jan. 6 UV and mate choice in the sailfin molly, Poecilia latipinna PALMER, MS; HANKISON, SJ*; Ohio Wesleyan University; Ohio Wesleyan University sjhankis@owu.edu There is growing evidence that the ultraviolet (UV) spectrum plays an important role in social communications for numerous vertebrates. Prior studies have demonstrated that UV characteristics in some fishes are […]
