Meeting Abstract 89.6  Friday, Jan. 6  Strut Your Stuff: Frontal Sinus Complexity in Bovidae and Carnivora CURTIS, Abigail A.*; FARKE, Andrew A.; Univ. of California, Los Angeles; Raymond M. Alf Museum of Paleontology abigailacurtis@gmail.com Paranasal sinuses, cavities found in the skulls of many mammal species, form when nasal epithelium pneumatizes surrounding bones. Of the paranasal sinuses, the […]

Meeting Abstract 89.1  Friday, Jan. 6  Extensible tissues and their contribution to macrostomy in snakes CLOSE, M T*; CUNDALL, D L; Lehigh University; Lehigh University mclose@lehigh.edu Snakes swallow by passing whole prey between their mandibles. In three species of macrostomatan snakes we examined, the intermandibular soft tissues stretch five to eight times their resting distance during feeding […]

Meeting Abstract 89.5  Friday, Jan. 6  Diversity of cranial morphology and jaw biomechanics in tetraodontiform fishes MCCORD, CHARLENE, L.; Univ. of Chicago cmccord@uchicago.edu The multiply subdivided adductor mandibulae muscles of tetraodontiform fishes provide an excellent model upon which to explore the biomechanical consequences of differential morphology. This work describes and compares the diversification of cranial shape, macro-architecture […]

Meeting Abstract 89.4  Friday, Jan. 6  Diet-Based Biomechanical Plasticity in Mouse Mandibles ANDERSON, P*; RAYFIELD, EJ; RENAUD, S; Univ. Bristol, UK; Univ. Bristol, UK; Univ. Lyon, France phil.anderson@bristol.ac.uk The functional consequences of morphological variation is a major field of inquiry in modern biology. The relationship between form and function can be complex, and this is especially true […]

Meeting Abstract 89.2  Friday, Jan. 6  Biomechanical properties of the intermandibulo-cervical integument of alligators: Implications for a more accurate understanding of the alligator feeding mechanism DUBANSKY, Brooke H.*; HOMBERGER, Dominique G.; Louisiana State Univ., Baton Rouge; Louisiana State Univ., Baton Rouge bhopki1@tigers.lsu.edu Alligators do not use their tongues to transport food from their oral cavity into their […]

Meeting Abstract 89.3  Friday, Jan. 6  A putative sensory organ in the mandibular symphysis of rorqual whales (Balaenopteridae) PYENSON, N.D.*; GOLDBOGEN, J.A.; VOGL, A.W.; SZATHMARY, G.; DRAKE, R.; SHADWICK, R.E.; Smithsonian Institution; Cascadia Research Collective; University of British Columbia; FPinnovations; Cleveland Clinic; University of British Columbia pyensonn@si.edu Marine vertebrates have evolved multiple solutions to the challenges of […]

Meeting Abstract 88.2  Friday, Jan. 6  Variation in the Glucocorticoid Stress Response and Behavior along a Gradient of Invasive House Sparrows (Passer domesticus) LIEBL, A.L*; GARRINGER, A.R.; WILEY, D.D; SIERRA, A.S.; MARTIN, L.B.; Univ. of S. Florida, Tampa, FL aliebl@mail.usf.edu Many invasive species show extensive phenotypic variation among populations of different ages. With the short time in […]

Meeting Abstract 88.5  Friday, Jan. 6  The genetic architecture of the bold-shy continuum in zebrafish, Danio rerio SINGER, M.L.*; OSWALD, M.E.; WIEDEBACK, B.D.; ROBISON, B.D.; Univ. of Idaho; Univ. of Notre Dame; Univ. of Idaho; Univ. of Idaho matt@mineral2.com Adaptation to captivity causes behavioral divergence among wild and captive populations. This divergence often occurs in a suite […]

Meeting Abstract 88.4  Friday, Jan. 6  Personality across ontogeny in an amphibian CARLSON, BE*; LANGKILDE, T; Penn State University; Penn State University bec169@psu.edu Animals often exhibit consistent individual differences in behavior (“personalities”) but the evolution of such diversity is poorly understood despite the importance of personality in behavioral ecology. Constrained behavioral flexibility across time may create tradeoffs […]

Meeting Abstract 88.1  Friday, Jan. 6  Opposites attract: Lobsters prefer to share dens with opposite behavioral phenotypes CHILDRESS, M.J.*; HELDT, K.A.; MCCLELLAN, K.L.; Clemson University; Clemson University; Clemson University mchildr@clemson.edu Caribbean spiny lobsters are known to be gregarious and are often found sharing dens with conspecifics. Previous work has found that gregarious lobsters may benefit from a […]
