Meeting Abstract 101.7  Thursday, Jan. 7  Sensory Stimulus and Reflex Response in Mammalian Swallowing GERMAN, RZ*; CROMPTON, AW; KONOW, N; THEXTON, AJ; Johns Hopkins Univ; Harvard Univ; Brown Univ; King’s College, London rz.german@jhmi.edu Several sensory stimuli can elicit the reflex motor response of a mammalian pharyngeal swallow. Some, such as direct stimulation of a sensory nerve, are […]

Meeting Abstract 101.5  Thursday, Jan. 7  Self-ReInnervation of the Lateral Gastrocnemius in Guineafowl CARR, J.A.*; BIEWENER, A.A.; Harvard University; Harvard University carr@fas.harvard.edu Running and walking requires that animals be able to negotiate variable terrain and recover from unexpected perturbations. Reflex responses that monitor and respond to changes in muscle force and length play an important role in […]

Meeting Abstract 101.8  Thursday, Jan. 7  Neural Control of the Snake Leg YOUNG, BA; Univ. Massachusetts Lowell Bruce_Young@uml.edu In vertebrates rhythmic alternating bilateral movements, such as the movements of the appendages typically seen during locomotion, are generated by a group of spinal motor neurons commonly termed a central pattern generator or CPG. While the CPGs associated with […]

Meeting Abstract 101.4  Thursday, Jan. 7  Mechanical Feedback of Antenna-Substrate Interaction Simplifies Cockroach Antennal Navigation MONGEAU, J.-M.*; JAYARAM, K.; LEE, J.; FULL, R.J.; COWAN, N.; University of California, Berkeley; University of California, Berkeley; Johns Hopkins University; University of California, Berkeley; Johns Hopkins University jmmongeau@berkeley.edu During high-speed wall following cockroaches rely on mechanosensory structures in their antennae to […]

Meeting Abstract 101.9  Thursday, Jan. 7  Linear Dynamical Models for Refuge Tracking Behaviors of the Weakly Electric Knifefish Eigenmannia virescens ROTH, E.S.*; ZHUANG, K.; STAMPER, S.A.; FORTUNE, E.S.; COWAN, N.J.; Johns Hopkins University, Baltimore, MD; Johns Hopkins University, Baltimore, MD; Johns Hopkins University, Baltimore, MD; Johns Hopkins University, Baltimore, MD; Johns Hopkins University, Baltimore, MD eatai@jhu.edu In […]

Meeting Abstract 101.2  Thursday, Jan. 7  Immunohistochemical and Histological Analyses Indicating the Presence of SCP-like Neuropeptides in Larval Crassostrea virginica (Bivalvia) ELLIS, IE*; KEMPF, SC; Auburn University; Auburn University ellisir@auburn.edu The Eastern oyster Crassostrea virginica is an important species within both estuarine ecosystems and the aquaculture industry. Investigating how the larval nervous system affects larval behaviors, such […]

Meeting Abstract 101.6  Thursday, Jan. 7  Effects of temperature on the motor control of chameleon feeding ANDERSON, C.V.*; DEBAN, S.M.; University of South Florida cvanders@mail.usf.edu Environmental temperature effects muscle contractile velocity and thus constrains the activity patterns of ectotherms. As temperature decreases, performance of muscle-powered movements such as locomotion and tongue protraction decline and hinder prey capture […]

Meeting Abstract 101.3  Thursday, Jan. 7  Discrete odor sampling of the Oregon shore crab Hemigrapsus oregonensis during ontogeny WALDROP, LD; Univ. of California, Berkeley lwaldrop@berkeley.edu Crabs, like many malacostracan crustaceans, sense chemical signals in their fluid surroundings using chemosensory hair arrays on antennules to discretely sample odor-laden fluid (sniffing). Sniffing occurs when a quick downstroke of the […]

Meeting Abstract 101.1  Saturday, Jan. 7  Phylogenetic clustering of commercially exploited fish species CHANG, J*; ROY, K; EASTMAN, JM; SMITH, SA; SANTINI, F; BAUM, JK; HASTINGS, PA; SIDLAUSKAS, BL; ALFARO, ME; Univ. of California, Los Angeles; Univ. of California, San Diego; Univ. of Idaho, Moscow; Brown Univ., Providence, RI; Univ. of California, Los Angeles; Univ. of California, […]

Meeting Abstract 101.5  Saturday, Jan. 7  Increased Energy Promotes Size-Based Niche Availability in Marine Mollusks MCCLAIN, Craig R.; National Evolutionary Synthesis Center cmcclain@nescent.org Variation in chemical energy, i.e food, availability is posited to lead to variation in body size. However, examinations of the relationship are rare and primarily limited to amniotes and zooplankton. Moreover, the relationship between […]
