SOCIETY FOR INTEGRATIVE AND COMPARATIVE BIOLOGY 2021 VIRTUAL ANNUAL MEETING (VAM)January 3 – Febuary 28, 2021 Meeting Abstract 72-3 Sat Jan 2 Can one control strategy unite all carangiform swimmers? Akanyeti, O*; Fetherstonhaugh, S; Aberystwyth University; Aberystwyth University ota1@aber.ac.uk Undulatory fishes display a wide range of body amplitudes and wavelengths during steady swimming. These kinematics variations can […]

South Dakota, Vermillion; Univ. South Dakota, Vermillion; Brown University, Providence Christopher.V.Anders@usd.edu http://www.chamaeleonidae.com Caribbean Anolis lizards have become a model system for the study of adaptive radiation and coevolution, whereby […]
Cranial shape variation in Crocodylomorpha and the influence of ecological transitions during its evolutionary history
Meeting Abstract 72-4 Monday, Jan. 6 08:45 – 09:00 Cranial shape variation in Crocodylomorpha and the influence of ecological transitions during its evolutionary history GODOY, PL; Stony Brook University pedrolorenagodoy@gmail.com Today, the 27 modern crocodylian species display similar morphologies and occupy comparable ecological niches in their semi-aquatic environments. However, Crocodylomorpha, the group that includes includes the extinct […]
Convergent evolution of craniofacial morphologies in apteronotid and mormyrid electric fishes
Meeting Abstract 72-3 Monday, Jan. 6 08:30 – 08:45 Convergent evolution of craniofacial morphologies in apteronotid and mormyrid electric fishes FORD, KL*; ALBERT, JS; University of Louisiana at Lafayette; University of Louisiana at Lafayette klf8880@louisiana.edu Weakly electric fishes provide an opportunity to examine multiple instances of morphological convergence across continents. Gymnotiformes and Mormyridae use weak electric signals […]
Avian sternum disparity and ecomorphological implications
Meeting Abstract 72-6 Monday, Jan. 6 09:15 – 09:30 Avian sternum disparity and ecomorphological implications BAUMGART, SL*; CLAESSENS, LPA; University of Chicago; Maastricht University slbaumgart@uchicago.edu The avian sternum anchors the main muscles powering flight and is highly disparate in morphology. For instance, some birds feature long, narrow sternal plates with deep keels, others have almost square sternal […]
Are Oral and Pharyngeal Jaw Diversification Rates Correlated in Cichlid Fishes
Meeting Abstract 72-1 Monday, Jan. 6 08:15 – 08:30 Are Oral and Pharyngeal Jaw Diversification Rates Correlated in Cichlid Fishes? BURRESS, ED*; WAINWRIGHT, PC; University of California, Davis; University of California, Davis edb0014@auburn.edu It has been appreciated for some time that the oral and pharyngeal jaws of fishes decouple prey capture and processing functions and their physical […]
Variation in Yolk Hormones in Follicles of the Painted Turtle
BOWDEN, RM*; EWERT, MA; NELSON, CE: Variation in Yolk Hormones in Follicles of the Painted Turtle Maternally derived yolk hormone levels vary seasonally in the painted turtle, Chrysemys picta, and this variation is correlated with offspring sex ratios in the laboratory. We examined variation in the concentration of three steroid hormones in three follicle size […]
The Effect of a Common Insecticide on Mosquitofish Morphology is Seasonally Dependent
PARK, D.; MINOR, M.D.; PROPPER, C.R.*: The Effect of a Common Insecticide on Mosquitofish Morphology is Seasonally Dependent Reproduction in many species follows a seasonal pattern governed by appropriate changes in endocrine physiology. Sensitivity to endocrine disrupting compounds (EDCs) may therefore vary seasonally as the endocrine system cycles. In order to determine if there is […]
