FESSLER, JL*; WESTNEAT, MW; Field Museum and Univ. of Illinois at Chicago; Field Museum, Chicago: Phylogenetics and Evolutionary History of the Butterflyfishes (Chaetodontidae) Marine butterflyfishes (116 sp.) are conspicuously beautiful and abundant animals found on coral reefs worldwide, yet there remains an absence of a well-supported molecular phylogeny. We present a new molecular phylogeny of […]

HANCOCK, Jennifer A.*; BIKNEVICIUS, Audrone R.; Ohio University; Ohio University: Phylogenetic analysis of foveation in birds The fovea is a specialized area of the retina thought to function to increase visual acuity. Among vertebrates there are a number of different retinal configurations including afoveate, unifoveate and bifoveate. Afoveate and unifoveate retinae are found throughout vertebrates, […]

JENKS, S. M.*; KHAN, S.; TRACY, K.; KENDALL, K.; The Sage Colleges; The Sage Colleges; The Sage Colleges; The Sage Colleges : Photoperiod influence on crayfish agonistic behavior Alterations in monoaminergic neurotransmission are thought to underlie photoperiodic variation in mood, aggression and affective disorders in humans. Research by several investigators on crayfish neurobiology has shown […]

The fiddler crab, Uca minax, has a complex lifecycle. Juvenile and adult […]

ANDERSON, C.J.*; WATERMAN, J.M.; ROTH, J.D.; University of Central Florida; University of Central Florida; University of Central Florida: Non-Invasive Identification of Individual Polar Bears by Whisker Spot Patterns Studies of free-ranging animals often require identifying individuals in a study population in order to obtain detailed data on population dynamics, movement patterns, and behavior. However, capturing […]

BOUDREAUX, M.L*; WALTERS, L.J.; University of Central Florida: Mytella charruana along the Atlantic Coast of Florida: A Successful Invasion? Biological invasions are now recognized as one of the most serious problems confronting the integrity of native species and ecosystems around the world. Unfortunately, invaders often go unnoticed until they have spread extensively, making eradication difficult […]

PATRICK, Lorelei E*; RUEDAS, Luis A; Portland State University; Portland State University: Multivariate morphological approaches to the ecological niche partitioning in Costa Rican bats (Mammalia: Chiroptera) The notion of �Ecological niche� has been defined a variety of ways; one significant definition is that of a multi�dimensional hypervolume constituted by all the factors influencing an animal�s […]
