Meeting Abstract 33.6 Monday, Jan. 5 Lanthanide Metals as Shark Repellants KAJIURA, Stephen M; Florida Atlantic University kajiura@fau.edu Sharks possess an exquisitely sensitive electrosensory system that enables them to detect voltage gradients in their environment. At close range, this sensory modality overrides other senses and provides the sharks with spatial information to localize their prey. The electric […]

How ribbon-fin swimmers swim
Meeting Abstract 33.5 Monday, Jan. 5 How ribbon-fin swimmers swim SHIRGAONKAR, Anup A; CURET, Oscar M; PATANKAR, Neelesh A; MACIVER, Malcolm A*; Northwestern University; Northwestern University; Northwestern University; Northwestern University maciver@northwestern.edu What is the propulsion mechanism for fish with elongated ribbon-like fins, such as weakly electric gymnotiform fish, the African Gymnarchus niloticus, and others? We combine computational […]
Estimation of information transfer rates in highly precise sensory afferents
Meeting Abstract 33.4 Monday, Jan. 5 Estimation of information transfer rates in highly precise sensory afferents FOX, Jessica L.*; DANIEL, Thomas L.; University of Washington; University of Washington jessfox@u.washington.edu To coordinate their motion, animals rely on sensory systems to acquire, process, and transmit necessary information from the environment. Dipteran insects use specialized structures known as halteres to […]

M.; HALPERN, M.; Oregon State University; Oregon State University; SUNY Downstate Medical Center, Brooklyn masonr@science.oregonstate.edu The Harderian gland of the red-sided garter snake, Thamnophis sirtalis parietalis, is a secretory structure that plays a […]
Evidence for chemical signalling systems (Glutamate, GABA and Nitric Oxide) involved in coordinated body contractions of Ephydatia muelleri
Meeting Abstract 32.1 Monday, Jan. 5 Evidence for chemical signalling systems (Glutamate, GABA and Nitric Oxide) involved in coordinated body contractions of Ephydatia muelleri. ELLIOTT, Glen RD*; LEYS, Sally P; University of Alberta gelliott@ualberta.ca Sponges are benthic suspension feeders that are considered to lack a tissue level of organization, sensory cells and coordinated behaviour. Recent molecular and […]
Understanding the role of lysozyme in birds physiological interactions between experimental immune enhancement and challenge
Meeting Abstract 31.1 Monday, Jan. 5 Understanding the role of lysozyme in birds: physiological interactions between experimental immune enhancement and challenge. MATSON, K.D.*; HORROCKS, N.P.C.; VERSTEEGH, M.A.; TIELEMAN, B.I.; University of Groningen; University of Groningen; University of Groningen; University of Groningen k.d.matson@rug.nl In pigeons, we examined the interactions between experimental immune enhancement and challenge. Immune enhancement took […]
Form and function of a novel metalloproteinase from the Eastern Oyster, Crassostrea virginica
Meeting Abstract 31.2 Monday, Jan. 5 Form and function of a novel metalloproteinase from the Eastern Oyster, Crassostrea virginica PROESTOU, DA*; SALGER, S; VAUGHN, C; GOMEZ-CHIARRI, M; University of Rhode Island dpro1791@postoffice.uri.edu Among vertebrates, matrix metalloproteinases (MMPs) are a well-studied family of enzymes. They are zinc-dependent, degrade the extracellular matrix, and play a critical role in many […]
Energetics, immunology and corticosterone response of four subspecies of stonechats in winter
Meeting Abstract 31.3 Monday, Jan. 5 Energetics, immunology and corticosterone response of four subspecies of stonechats in winter VERSTEEGH, MA*; HELM, B; GOYMANN, W; TIELEMAN, BI; University of Groningen; Max Planck Institute for Ornithology; Max Planck Institute for Ornithology; University of Groningen m.a.versteegh@rug.nl The balance between current and future reproduction is one of the foundations of life […]
Sickness behavior and fever vary among free-living sparrows along a life history gradient
Meeting Abstract 30.3 Monday, Jan. 5 Sickness behavior and fever vary among free-living sparrows along a life history gradient ADELMAN, J. S.*; WIKELSKI, M. C.; HAU, M.; Princeton University; Max Planck Institute for Ornithology; Max Planck Institute for Ornithology jsadelma@princeton.edu Studies in ecological immunology suggest that organisms trade-off the limited resources of time, nutrients, and energy between […]
Latitudinal Variation in Winter Immune Function in a Differential Migrant
Meeting Abstract 30.1 Monday, Jan. 5 Latitudinal Variation in Winter Immune Function in a Differential Migrant O’NEAL, DM*; SWANGER, L; KETTERSON, ED; Indiana University; Indiana University; Indiana University daoneal@indiana.edu Sex differences in migratory behavior (differential migration) can give rise to sexual segregation during the non-breeding season. The dark-eyed junco (Junco hyemalis) is one such differential migrant with […]
