Meeting Abstract 68.4 Monday, Jan. 6 08:45 Proportional psychophysics and the evolution of behavior: The broad influence of Weber’s law AKRE, K.L.*; JOHNSEN, S.; Duke University; Duke University karin.akre@gmail.com Animal decision-making guides reproduction, foraging, predator avoidance, navigation, aggression, and every area of behavior. Sensory systems that translate physical stimuli into perceived quantities allow animals to make decisions […]

Bioelectric crypsis in cephalopods reduces detection by shark predators
Meeting Abstract 68.1 Monday, Jan. 6 08:00 Bioelectric crypsis in cephalopods reduces detection by shark predators BEDORE, CN*; KAJIURA, SM; JOHNSEN, SJ; Duke University; Florida Atlantic University; Duke University christine.bedore@duke.edu The ability of cephalopods to camouflage themselves is well documented as a defense against predation. However, visual camouflage is only effective against primarily visual predators. For example, […]
Using experimental and simulated footprints to interpret dinosaur limb motion
Meeting Abstract 67.6 Monday, Jan. 6 09:15 Using experimental and simulated footprints to interpret dinosaur limb motion FALKINGHAM, P L *; GATESY, S M ; Royal Veterinary College; Brown University pfalkingham@rvc.ac.uk Dinosaur tracks offer a primary source of evidence for understanding not only the behaviours of individual taxa, but also the broader view of locomotor evolution through […]

Maximal locomotor performance and sprint sensitivity in green anole lizards (Anolis carolinensis)
Meeting Abstract 67.5 Monday, Jan. 6 09:00 Maximal locomotor performance and sprint sensitivity in green anole lizards (Anolis carolinensis) HUSAK, J.F.*; SATHE, E.A.; Univ. of St. Thomas jerry.husak@stthomas.edu Locomotion is arguably one of the most important traits to the survival and reproductive success of animals and has been the subject of intense study for decades. However, locomotion […]
In vivo Femoral Strains in Swimming Turtles Influence of Locomotor Medium on Limb Bone Loading
Meeting Abstract 67.1 Monday, Jan. 6 08:00 In vivo Femoral Strains in Swimming Turtles: Influence of Locomotor Medium on Limb Bone Loading YOUNG, V.KH.*; BLOB, R.W. ; Clemson University; Clemson University vkhilli@clemson.edu Many terrestrial vertebrate lineages have members that have returned to aquatic habitats. Such taxa often show characteristic changes in limb bone shape, such as flattening […]
Implications of Morphological Variation in the Manual Unguals of Theropod Dinosaurs
Meeting Abstract 67.4 Monday, Jan. 6 08:45 Implications of Morphological Variation in the Manual Unguals of Theropod Dinosaurs NOTO, C.R.; University of Wisconsin-Parkside, Kenosha noto@uwp.edu Among living tetrapods, research shows a strong correlation between claw shape and such factors as locomotor mode or predatory behavior. Using a similar approach to dinosaur unguals we may expect that differences […]
Wood frog adaptations to overwintering in Alaska New limits to freezing tolerance
Meeting Abstract 66.4 Monday, Jan. 6 08:45 Wood frog adaptations to overwintering in Alaska: New limits to freezing tolerance. LARSON, DJ*; MIDDLE, L; BARNES, BM; Univ of Alaska Fairbanks djlarson@alaska.edu We investigated the ecological physiology and behavior of wood frogs (Lithobates [Rana] sylvaticus) overwintering in Interior Alaska by tracking animals into natural hibernacula, recording microclimate, and determining […]
