Effect of Anesthesia Immersion on the Coral Catshark, Atelomycterus marmoratus
Meeting Abstract 133-1 Tuesday, Jan. 7 13:30 – 13:45 Effect of Anesthesia Immersion on the Coral Catshark, Atelomycterus marmoratus LEVENDOSKY, MW*; LANIER, M; BEDORE, CN; Georgia Southern University; Georgia Southern University; Georgia Southern University ml06458@georgiasouthern.edu Sensory experiments require anesthesia so the animal is immobilized. Traditional fish anesthetics (e.g. tricaine) depress the sensory system, although the degree to […]

Examining factors influencing body size change for insular rodents
Meeting Abstract 133.1 Monday, Jan. 7 Examining factors influencing body size change for insular rodents DURST, PAP*; ROTH, VL; Duke University; Duke University paul.durst@duke.edu When organisms colonize an island, they often undergo dramatic shifts in size. This phenomenon has been observed in birds, reptiles, amphibians and even plants, but it is especially evident among mammals, where insular […]
