DOUGLAS, J.M.*; DOMINY, N.J.; University of Chicago; University of Chicago: Light Habitats and the Functional Ecology of Polarized Iridescence in Neotropical Butterflies Sweeney et al. (2003; Nature 423:31-32) describe the use of polarized light as a mating signal in Heliconius cydno butterflies. In addition, they hypothesized that exploitation of polarized light to detect mates may […]

MENZE, M.A.*; HUTCHINSON, K.; HAND, S.C.; Louisiana State Univ., Baton Rouge; Louisiana State Univ., Baton Rouge; Louisiana State Univ., Baton Rouge: Lack of a calcium-induced mitochondrial permeability transition in Artemia franciscana during early development. When mammalian mitochondria are exposed to high calcium in the presence of phosphate, a massive swelling, uncoupling of respiration and release […]

THOMPSON, J.T.*; LOBO, K.M.; St. Joseph’s University, Philadelphia, PA; St. Joseph’s University, Philadelphia, PA: Kinematics of the escape jet in paralarval squids. The mantle and funnel of squids are essential in generating and modulating thrust for jet locomotion. Previous research has demonstrated that aspects of the morphology, kinematics, and mechanics of the mantle and funnel […]

MARTIN, RA*; PFENNIG, DW; University of North Carolina at Chapel Hill; University of North Carolina at Chapel Hill: Kin competition and the evolution of polyphenism Because they share similar phenotypes and needs, competition for resources should be greatest among closely related individuals. One way to minimize such harmful competition is to disperse from the natal […]

ALLMAN, Phil; ROOSENBURG, Willem; Ohio University; Ohio University: Intraspecific variation in reproductive strategies of a wide ranging turtle Understanding the importance of intraspecific phenotypic differentiation among wide ranging populations remains at the core of life history research. Phenotypic variation in life history traits such as offspring size, growth, and survivorship are the target of studies […]

LOVE, OP*; SALVANTE, KG*; DALE, J; WILLIAMS, TD; Simon Fraser University; Simon Fraser University; Simon Fraser University; Simon Fraser University: Intersexual differences in immunity through different life-history stages The study of immunity has become an important focus of numerous studies on fitness-related trade-offs. In particular, researchers have examined potential trade-offs between immune function and such […]

ADDIS, E.*; WACKER, D.; CLARK, A.; COVERDILL, A.; MEDDLE, S.; WALKER, B.; LANDYS, M.; RENEERKENS, J., WINGFIELD JC; Landys, M., Reneerkens J.; Univ. of Washington; Univ. of Washington; Univ. of Washington; Univ. of Washington; Univ. of Edinburgh; Univ. of Washington; Univ. of Washington; NIOZ, Univ. of Washington: Influence of habitat condition on breeding in Plectrophenax […]

YOUNG, R. L.; BADYAEV, A. V. ; University of Arizona; University of Arizona: Influence of Muscle Attachment on Morphological Integration in the Shrew Mandible Understanding the evolution of complex trait is a fundamental question in evolutionary biology. Central to this question is the role of correlations or integration among components of a complex trait. For […]

KHODABANDEH, S.; TALAEI, R.*; Univ. of Tarbiat Modarres, Tehran, IRAN and UMII, Montpellier, FRANCE; Univ. of Tarbiat Modarres, Tehran, IRAN : Immunocytochemical localization of Na/K-ATPase in the gut of the Zygopteran larvae (Odonata) Damselflies (Zygopteran) are an interesting group of insects because their larvae are fully aquatic while the adults are terrestrial. Insects larvae living […]

SAWYER, Sara J.; UHL, Nicholas; Southern Illinois Univeristy; Southern Illinois University: Identification of an integrin and integrin associated proteins in the sea anemone, Aiptasia pulchella, and the hydroid, Hydra littoralis Integrins are an ancient group of animal adhesion receptors that attach cells to the extracellular matrix. Integrins are composed of heterodimeric transmembrane proteins consisting of […]
