In search of evolutionary origin of cichlids among percomorph fishes
Meeting Abstract 49.6 Monday, Jan. 5 In search of evolutionary origin of cichlids among percomorph fishes CHEN, Wei-Jen*; MAYDEN, Richard L.; Saint Louis University wjchen.actinops@gmail.com The family Cichlidae is one of the most diverse clades of freshwater fishes. Species from this group are a major component of the modern ichthyofauna in their native freshwater habitats, and constitute […]
Contrasting effects of substrate on population genetic structure in sympatric rock-dwelling cichlids
Meeting Abstract 49.4 Monday, Jan. 5 Contrasting effects of substrate on population genetic structure in sympatric rock-dwelling cichlids WAGNER, C.E.*; MCCUNE, A.R.; Cornell University; Cornell University cew35@cornell.edu The cichlid fishes of Lake Tanganyika in Eastern Africa are a celebrated example of both ecological and species diversification. Because population subdivision is likely to play an important role in […]

Underwater gecko feet – how clingfish and snailfish adhere to wet surfaces
Meeting Abstract 48.6 Monday, Jan. 5 Underwater gecko feet – how clingfish and snailfish adhere to wet surfaces SUMMERS, A.P.*; GORB, S.; UC Irvine; University of Kiehl asummers@uci.edu Clingfishes (Gobiesocidae) and snailfishes (Liparidae) have independently evolved, ventral suction disks that they use to adhere to substrates with unpredictable surface characteristics. Adhesion is completely underwater and appears largely […]

Morphological and Biomechanical Variation in the Stomatpod Cuticle
Meeting Abstract 48.1 Monday, Jan. 5 Morphological and Biomechanical Variation in the Stomatpod Cuticle ANDREW, J*; GEORGE, M; PATEK, S; SWANSON, B; Gonzaga University; Gonzaga University; University of California, Berkeley; Gonzaga University jandrew@gonzaga.edu The stomatopod crustacean dactyl, a highly derived appendage, can repeatedly smash open very hard snail shells, producing cavitation and impact forces in excess of […]
Evolution of supercontraction in spider silk
Meeting Abstract 48.5 Monday, Jan. 5 Evolution of supercontraction in spider silk BOUTRY, C.**; BLACKLEDGE, T.A.; University of Akron; University of Akron cb54@uakron.edu Spider silk is a high performance material renowned for its tensile properties. However, silk can also strongly contract when exposed to high humidities (~70%) and shrink by up to 50%, generating high stresses (~50 […]
Co-evolution of silk material properties with spider webs
Meeting Abstract 48.3 Monday, Jan. 5 Co-evolution of silk material properties with spider webs SENSENIG, Andrew T.*; AGNARSSON, Ingi; BLACKLEDGE, Todd A.; University of Akron; University of Akron; University of Akron a_sensenig@yahoo.com Silk fibers spun by spiders perform varied and numerous roles, but have been studied most intensively in the context of prey capture in webs. Orb-weaving […]
