MARSHALL, C.D.; KOVACS, K.M.; LYDERSEN, C.; Texas A&M University at Galveston; Norwegian Polar Institute; Norwegian Polar Institute: Behavioral Performance of Feeding in Bearded Seals (Erignathus barbatus) Bearded seals are arctic phocids that feed predominantly on benthic prey. Walruses, well-known benthic feeders, exhibit specialized behaviors such as suction and hydraulic jetting. To understand the feeding capabilities […]

LIGNOT, Jean H; SECOR, Stephen M; CNRS University Louis Pasteur; University of Alabama: Apoptosis in the intestinal mucosa of the Burmese python Burmese pythons (Python molurus) are highly adapted to infrequent feeding, up and down-regulating their gastrointestinal performance at the beginning and completion of each meal. Highlights of this response are 5 to 20-fold increases […]

TURBEVILLE, J.M.; SMITH, D.M.; Virginia Commonwealth Univ.; Virginia Commonwealth Univ.: Analysis of Nemertean Mitochondrial Gene Arrangements: Implications for Phylogenetic Inference Nemerteans have played a pivotal role in hypotheses of bilateral metazoan evolution and despite extensive analyses of morphological and gene sequence data separately and simultaneously, the precise placement of the taxon within the Lophotrochozoa remains […]

GANDOLFI, B.M.*; BOBINO, C.; SECOR, S.M.; University of Alabama, Tuscaloosa; Stillman College, Tuscaloosa; Univesity of Alabama, Tuscaloosa : Allometric scaling of intestinal performance for colubrid snakes Intraspecific and interspecific scaling relationships between metabolic, physiologic, and morphologic parameters and body size are well documented. Lacking although is any assessment of the allometric scaling of digestive performance. […]

CHEROSKE, AG; CRONIN, TW; University of Maryland, Baltimore County; University of Maryland, Baltimore County: �All in favor, say eye�: Adaptive color and postural signaling by stomatopod crustaceans in different light environments. Stomatopods (mantis shrimp) are aggressive benthic marine predators with color vision plausibly better than any animal. Because many stomatopods use ritualized displays of conspicuously […]

NYLUND, K.L.*; SCHNEIDER, K.R.; HELMUTH, B.S.T.; University of South Carolina: A fine scale study of thermal heterogeneity and mussel (Mytilus spp.) species distribution in San Francisco Bay Thermal stress is considered a primary abiotic factor setting geographic species distribution limits. If temperature plays a prominent role in setting large scale distribution patterns, then this pattern […]

RICE, Amber M.; University of North Carolina, Chapel Hill: A Phylogeographic Investigation of Character Divergence Closely related species often express different phenotypes in sympatry, but not in allopatry. Two spadefoot toad species (Spea bombifrons, S. multiplicata) exhibit this pattern of character divergence in tadpole morph production. Earlier studies on these species link resource competition in […]
