SEP�LVEDA, R.D.; Universidad Austral de Chile: Analyzing allometry in an intertidal gastropod using geometric morphometrics Traditional morphometrics have assumed that gastropod shells grow at isometric fashion. Geometric morphometrics is specifically aimed to characterize changes in shape independent of size. The aim of this study was to determine the variation in shape in the intertidal snail […]

FADAEL, Rudgie *; T�MKIN, Ilya ; DESALLE, Rob; BOLNET, Carolle; Medgar Evers College ; American Museum of Natural History; American Museum of Natural History; Medgar Evers College : Analysis of Shape Variation in Several Populations of Bivalves Genus Pinctada The main purpose of the project was to test if phenotypically similar populations of bivalves from […]

CONNELLY,, P.W.*; TURNER,, R.L.; Florida Institute of Technology, Melbourne: Analysis of High Intertidal Algal Communities: Comparisons between Living and Non-Living Substrata Living and non-living substrata differ in their chemical cues and the microhabitats that they present to settling organisms. These differences allow for variations in physical and biological conditions experienced at the surfaces of both […]

CORBIN, C.E.*; MILES, D.B.; ERNST, N.; Bloomsburg University of Pennsylvania; Ohio University, Athens; Bloomsburg University of Pennsylvania: Age of evolutionary origin or ecological diversity: which better explains the morphological disparity of New World flycatcher clades? Evolution of sister groups within a monophyletic clade is due to a combination of common and unique evolutionary processes. In […]

ZOU, E.*; STUEBEN, B.; Nicholls State University, Thibodaux, LA: Acute exposure to naphthalene reduces oxyregulating capacity of the brown shrimp, Penaeus aztecus, subjected to progressive hypoxia The brown shrimp, Penaeus aztecus, in the northern Gulf of Mexico is faced with dual stresses of environmental hypoxia, which occurs as a result of nutrients input from the […]

KHODABANDEH, Saber*; SHAHRIYARI, Mohsen; Univ. of Tarbiat Modarres; Univ. of Tarbiat Modarres: Accumulation and the toxic effects of Mercury on survival and gill structure of Mugil auratus Mugil auratus (1-3 gr) were exposed to different concentration (30, 70, 140 and 600 ppb) of mercury for 4 days. After exposure, Mugil gills were removed and analyzed […]

RHYNE, A.L.**; LIN, J.; Florida Institute of Technology; Florida Institute of Technology: A western Atlantic peppermint shrimp complex: redescription of Lysmata wurdemanni (Gibbes), description of four new species and remarks on L. rathbunae Chace (Crustacea: Decapoda: Hippolytidae) The present study is the first revision of the western Atlantic peppermint shrimp complex Lysmata wurdemanni (Gibbes). Lysmata […]

MAH, C.L.; Smithsonian Institution: A new species of Xyloplax (Echinodermata; Asteroidea; Concentricycloidea) from the Northeast Pacific: Comparative Morphology and A Reassessment of Concentricycloid Phylogeny Deep-sea environments are often home to unusual organisms which display novel morphological innovations with highly derived body plans. Among the most enigmatic of these taxa are the rarely encountered Concentricycloidea or […]

WILLIAMS, R.M.; PRICE, R.M.*; Fayetteville State University; University of North Carolina at Chapel Hill: A mathematical model for exploring the trade-offs in energy associated with growing gastropod shells If the whorls in a gastropod shell overlap, as they do in a tightly-coiled shell, then the animal requires less material to grow its shell. Because the […]

MANDICA, Mark L; University of Miami, Florida: A comparison of photoperiod related activity patterns between two South Florida toads (Anura: Bufonidae) Early natural history notes (Hamilton, 1955; Wright & Wright, 1948; and Duellman & Schwartz, 1958) described the oak toad, Bufo quercicus, as diurnal. These descriptions are postulated upon field observations, but have never been […]
