Meeting Abstract 75.2  Sunday, Jan. 6  Dynamics of head rotation in feeding pipefish and seahorses VAN WASSENBERGH, S*; AERTS, P; Universiteit Antwerpen; Universiteit Antwerpen sam.vanwassenbergh@ua.ac.be A recent study showed that the extremely high speed at which pipefish (Fam. Syngnathidae) are able to rotate their snout towards prey and capture it by suction is probably caused by a […]

Meeting Abstract 75.1  Tuesday, Jan. 6  Biophysical factors affecting gas exchange in sea turtle nests O’CONNOR, M.P.*; HONARVAR, S.; SOTHERLAND, P.R.; SPOTILA, J.R.; Drexel Univ.; Drexel Univ.; Kalamazoo Coll.; Drexel Univ. mike.oconnor@drexel.edu The sandy environment of developing sea turtle eggs creates a significant resistance to both diffusive and convective exchanges of respiratory gases. Data suggest that the […]

Meeting Abstract 75.4  Tuesday, Jan. 6  Avian seasonal metabolic adjustments in a southern subtropical desert: winter down-regulation of basal metabolic rate SMIT, B.; MCKECHNIE, A.E.*; Univ. of Pretoria; Univ. of Pretoria aemckechnie@zoology.up.ac.za One of the major patterns of phenotypic flexibility in avian basal metabolic rate (BMR) consists of seasonal adjustments.
