Folliculogenesis of juvenile American alligators (Alligator mississippiensis) and the role of genetic regulation of gonadal hormones in ovarian follicle formation as a study in life history
CHUNG, Koo-Whang*; MCEDWARD, Lari/A; MOORE, Brandon/C; MILNES, Matthew/R; IGUCHI, Taisen; GUILLETTE, Louis/J; University of Florida: Folliculogenesis of juvenile American alligators (Alligator mississippiensis) and the role of genetic regulation of gonadal hormones in ovarian follicle formation as a study in life history The development of ovarian follicles in the American alligator does not occur in the […]
Feeding Kinematics of the Grotto Salamander Eurycea spelaea
HUSTON, MM*; ASHLEY-ROSS, MA; Wake Forest University; Wake Forest University: Feeding Kinematics of the Grotto Salamander Eurycea spelaea Typically, troglobitic salamanders remain paedomorphic due to greater availability of prey items in the water as opposed to on the dry substrate. In contrast, the cave dwelling grotto salamander, Eurycea spelaea (Stejneger, 1893) transforms from aquatic to […]
External power production in walking and running under simulated gravity changes correlation with metabolic cost
NORDGREN, A; BUTCHER, MT; BERTRAM, JEA*; Florida State Univ., Tallahassee; Univ. of Calgary, Calgary; Univ. of Calgary, Calgary: External power production in walking and running under simulated gravity changes: correlation with metabolic cost Studies have shown that the metabolic cost of running decreases with decreases in gravity (g) but this is only marginally the case […]
External Features of Several Sexually Abnormal Fiddler Crabs, Uca pugilator
ZOU, E.; Nicholls State University, Thibodaux, LA: External Features of Several Sexually Abnormal Fiddler Crabs, Uca pugilator Like other brachyuran crustaceans, fiddler crabs, Uca pugilator, are normally gonochoristic, exhibiting striking sexual dimorphism. Males are characterized by a pair of extremely asymmetrical chelipeds and a narrow abdomen while females typically have a pair of small, identical […]
Experimental observations on symphyseal fusion in selenodont artiodactyls
WILLIAMS, SH*; VINYARD, CJ; WALL, CE; HYLANDER, WL; Ohio University; NEOUCOM; Duke University; Duke University: Experimental observations on symphyseal fusion in selenodont artiodactyls In most mammals, the mandibular symphysis is a mobile joint in which the two dentaries are united by ligaments, fibrocartilage and interdigitating bony rugosities. In some mammalian clades, however, the symphysis ossifies […]
Evolving Student Attitudes Teaching Evolution in Arkansas
LOVELY, E.C.*; KONDRICK, L.C.; Arkansas Tech Univ.; Arkansas Tech Univ.: Evolving Student Attitudes: Teaching Evolution in Arkansas. Teaching college students about the nature of science should not be a controversial exercise. College students are expected to understand the difference between science and pseudoscience. They are expected to accept astronomy as science, and astrology as mysticism. […]
Evaluating discrimination performances of the seed beetle, Callosobruchus maculatus (F)
YANG, R. L.*; FUSHING, H.; HORNG, S. B.; National Taiwan University; Univ. of California, Davis; National Taiwan University: Evaluating discrimination performances of the seed beetle, Callosobruchus maculatus (F.) Many parasitic and endophagous species are capable of discriminating the quality of their hosts. However, it is still difficult to evaluate an animal�s discrimination performance. In this […]
Estrogen receptor-related receptors in the Atlantic killifish Fundulus heteroclitus diversity, expression, and estrogen responsiveness
TARRANT, A.M.*; GREYTAK, S.R.; CALLARD, G.V.; HAHN, M.E.; Woods Hole Oceanographic Institution, MA; Boston University, MA; Boston University, MA; Woods Hole Oceanographic Institution, MA: Estrogen receptor-related receptors in the Atlantic killifish Fundulus heteroclitus: diversity, expression, and estrogen responsiveness Estrogen receptor-related receptors (ERRs) are a group of nuclear receptors that are phylogenetically related to estrogen receptors.
