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 […]

While bivalve mollusks […]

ROBERTSON, Bruce; University of Montana: A Cognitive Perspective on Evolutionary Traps Evolutionary traps describe situations in which, due to some rapid change in conditions, formerly reliable behavioral cues instead trigger maladaptive behaviors. While the concept of an evolutionary trap is widely recognized, existing conceptual models have been insufficient to describe their mechanistic bases. Focusing on […]

SELCER, KW*; VERBANIK, JL; Duquesne Univ; Duquesne Univ: Vitellogenin in the Northern Leopard Frog (Rana pipiens): Purification, Characterization and Development of a Immunoassay Vitellogenin is the egg-yolk precursor protein for all oviparous vertebrates. It is produced by the female liver under estrogen stimulation. Recently, vitellogenin has proven useful as a biomarker for endocrine disruption in […]

POLK, J.D.*; LIEBERMAN, D.E.; BETZ, A.E.; DEMES, B.; University of Illinois; Harvard University; University of Illinois; Stony Brook University: Validation of a non-invasive model for predicting long bone loading Functional interpretation of limb bone cross-sectional geometry depends upon knowledge of the magnitude and direction of habitual loading. Quantification of bone loading has only been possible […]
