Meeting Abstract 44.3  Sunday, Jan. 5 11:00  Nestling growth rate and juvenile survival MANESS, TJ*; ANDERSON, DJ; Louisiana Tech University; Wake Forest University tmaness@latech.edu The survival probability of birds during the juvenile period, between the end of parental care and adulthood, is highly variable and has a major effect on population dynamics and parental fitness. As such, […]

Meeting Abstract 44.2  Sunday, Jan. 5 10:45  Individual variation in provisioning effort does not result in larger offspring at fledging FOWLER, MA*; WILLIAMS, TD; Simon Fraser University; Simon Fraser University melinda.a.f@gmail.com Parents that work harder at raising young should obtain fitness benefits but, theoretically, these benefits should come at some ‘cost of reproduction’. However, the predicted positive […]

Meeting Abstract 44.1  Sunday, Jan. 5 10:30  Gestational weight gain influences sex ratios at birth in humans NAVARA, KJ; Univ. of Georgia knavara@uga.edu Previous studies in birds and non-human mammals suggest that females bias the sex ratios of offspring in response to resource limitations. In addition, a previous study in humans indicated that women with high levels […]

The hyoid arch is medial to […]

Meeting Abstract 43.6  Sunday, Jan. 5 11:30  Morphology of the Feeding Apparatus in Four Shark Species BALABAN, J.P.*; WILGA, C.D.; Univ. of California, Irvine; Univ. of Rhode Island jbalaban@uci.edu Sharks have an incredible diversity of feeding mechanisms for a group with so few extant species. To understand the relationship between the morphology of the shark feeding apparatus […]

R. ; Marshall University okeefef@marshall.edu The gray wolf, Canis lupus, exhibits both genetic and morphologic clinal variation across North America. While shape variation in wolf populations has been documented, no study has been […]

Meeting Abstract 43.5  Sunday, Jan. 5 11:15  Convergence in morphology and masticatory function between the pharyngeal jaws of grass carp and oral jaws of mammalian herbivores GIDMARK, NJ*; TARRANT, J; BRAINERD, EL; Brown University gidmark@uw.edu Herbivory is a mechanically difficult dietary specialization, as plant cell walls are chemically inert. In evolutionary shifts to herbivory, many amniotes (especially […]
