Meeting Abstract P1.99  Jan. 4  Thermal Microhabitat Selection in Hatchling Anoles WALGUARNERY, J.W.; University of Tennessee jwalguar@utk.edu The Caribbean lizards of the genus Anolis serve as a model taxon in the study of interspecific competition and comprise the basis for one of the most well-developed conceptualizations of multidimensional niche partitioning. Lizards, as ectothermic vertebrates, depend on variation […]

Meeting Abstract P1.4  Jan. 4  The role of hedgehog signaling during craniofacial development in larval zebrafish. O’QUIN, C.T.*; GROSS, J.S.; HERNANDEZ, L.P.; George Washington University, Washington, DC ctoquin@gwu.edu Hedgehog signaling has been shown to play an important role in the proper growth and development of a number of embryonic tissues. Indeed, the role of hedgehog signaling during […]

Meeting Abstract P1.120  Jan. 4  The function of bright male coloration in the sunset spider, Frigga pratensis (Salticidae) TAYLOR, L. A.; Arizona State University Lisa.A.Taylor@asu.edu Several jumping spiders (Salticidae) are sexually dichromatic � females are inconspicuous while males have vivid colors. Here, I test three hypotheses about the function of male coloration in the sunset spider (Frigga […]
