Meeting Abstract 63.2  Sunday, Jan. 6  Between a rock and a hard place: The relative importance of geology, substrates, and their properties to rocky intertidal communities PEROTTI, Elizabeth A.*; LINDBERG, David R.; University of California, Berkeley; University of California, Berkeley marinelizard@berkeley.edu Understanding the effects of geology and geologic history on communities and species is imperative for interpreting […]

Meeting Abstract 62.5  Saturday, Jan. 5  Vicariance or pseudocongruence? Multispecies phylogeography in the northeastern Pacific MCGOVERN, TM*; HART, MW; SASKI, C; MARKO, PB; Clemson Univ.; Simon Fraser Univ.; Clemson Univ.; Clemson Univ. tmcgove@clemson.edu Comparative phylogeography often reveals the existence of shared phylogeographic breaks across co-distributed species, consistent with a hypothesis of vicariance, in which a single event […]

Meeting Abstract 62.2  Saturday, Jan. 5  To brood or not to brood: the role of reproductive mode in the dispersal of Antarctic benthic invertebrates MAHON, A.R.*; HALANYCH, K.M.; Auburn University; Auburn University armahon@gmail.com Antarctica is a region of extreme isolation and its fauna include a high number of endemic organisms, many of which are described as circumpolar. […]

Meeting Abstract 62.4  Saturday, Jan. 5  Speciation patterns in Patagonia: insights from Aegla freshwater crabs PEREZ-LOSADA, Marcos*; XU, Jiawu; JARA, Carlos; CRANDALL, Keith A; Brigham Young University; Brigham Young University; Universidad Austral de Chile; Brigham Young University mp323@byu.edu The role of historical events such as glacial cycles, mountain building, and river captures on the speciation and demographic […]

Meeting Abstract 62.6  Saturday, Jan. 5  Phylogeography of Moray Eels in the Indo-Pacific REECE, Joshua S; Washington University in Saint Louis jsreece@wustl.edu Coral reef fish migration during the pelagic larval period has been shown to play a major role in determining regional population genetic structure. Moray eels (Muraenidae) have some of the longest larval durations among coral […]

Meeting Abstract 62.1  Saturday, Jan. 5  Larval dispersal and evolutionary history of Antarctic benthic fauna HALANYCH, K.M.*; SCHELTEMA, R.S.; Auburn University; Woods Hole Oceanographic Institution ken@auburn.edu Roughly 30-35 MYA, the separation of the Antarctic continent from the South American plate formed the Drake Passage and the Antarctic circumpolar current (ACC). The presence of the ACC has been […]

Meeting Abstract 62.3  Saturday, Jan. 5  Comparative phylogeography of two ophiuroid species from Antarctica HUNTER, R.L.*; SANTOS, S.R.; HALANYCH, K.M.; Auburn University; Auburn University; Auburn University belchrl@auburn.edu Isolation of Antarctica has been a driving evolutionary force for Southern Ocean fauna for ~41 million years. Separation of Antarctica from South America and the ensuing onset of the Antarctic […]

Meeting Abstract 61.6  Saturday, Jan. 5  Night and Day Comparisons of Predatory Reef Fish BASSETT, DK*; MONTGOMERY, J; University of Auckland, Auckland, New Zealand; University of Auckland, Auckland, New Zealand dbassett@mail.uri.edu Nocturnal predatory fishes are an important component of marine ecosystems, yet few studies have investigated them in any detail. This study used a relatively new methodology, […]

Meeting Abstract 61.5  Saturday, Jan. 5  Mucus-net feeding behavior by Olivella semistriata, an intertidal snail on sandy beaches MCPHERSON, D.R.; SUNY at Geneseo mcpherso@geneseo.edu Olivella semistriata is a prosobranch gastropod mollusc in the family Olividae, and it is abundant on gently sloping sandy beaches along the Pacific coast of Central America.
