Meeting Abstract 2-3  Saturday, Jan. 4 08:30 – 08:45  Cuticular hydrocarbons and the integration of myrmecophile rove beetles into ant colonies NARAGON, TH*; BRüCKNER, AK; WIJKER, RS; SESSIONS, AL; PARKER, J; Caltech; Caltech; Caltech; Caltech; Caltech tnaragon@caltech.edu Cuticular hydrocarbons (CHCs) play a dual role in insects: they prevent against water loss across the cuticle and they are […]

Meeting Abstract 2-2  Saturday, Jan. 4 08:15 – 08:30  Climate-related variation in metabolic rate across the geographic range of an invasive ectotherm POWERS, SD*; THOMPSON, LM; PARRY, D; GRAYSON, KL; AGOSTA, SJ; Virginia Commonwealth University; Clemson University; State University of New York; Virginia Commonwealth University powerssd3@vcu.edu Our current understanding of how physiological traits respond to divergent climates […]

NAUEN, J.C.*; LAUDER, G.V.: Small-scale flow around the finlets and caudal peduncle of free-swimming chub mackerel (Scomber japonicus) The trajectory and speed of flow in the vicinity of the finlets (small fins on the dorsal and ventral body margin anterior to the caudal fin) and caudal peduncle of chub mackerel (Scomber japonicus) swimming steadily in […]

FREUND, E.V.*; DEWAR, H.; CROLL, D.A.: Locomotor Tracking of the Spine-tailed Devil Ray, Mobula japanica Three-dimensional movements and foraging ecology of a small manta ray species, the spine-tailed devil ray, Mobula japanica, were monitored using acoustic tracking (n = 2) and archival tagging techniques (n = 4) in the southern Sea of Cortez. The rays […]

LIAO, J.: Locomotion in needlefish: anguilliform swimming with fins Anguilliform locomotion involves the undulation of an elongate body axis and is characteristic of a diverse array of vertebrates, ranging from fishes to salamanders and reptiles. The Atlantic needlefish, Strongylura marina, is an elongate fish that displays anguilliform locomotion and also possesses a typical percomorph fin […]

Lauritzen, D.V.*; Hertel, F.; Gordon, M.S.: Kinematics of Salmon Leaping Up Waterfalls Fish ladders have been used for hundreds of years to help migratory fishes move upstream past human-made obstacles such as dams. The designs of these ladders appear to have given little consideration to the behaviors and leaping abilities of the fishes they are […]

DRUCKER, E.G.*; LAUDER, G.V.: Function of the teleost dorsal fin: experimental analysis of wake forces in sunfish A major structural transformation characterizing the evolution of teleost fishes is the elaboration of the dorsal fin into anterior spiny and posterior soft-rayed portions. As yet, however, there are no hydrodynamic data on the functions served by these […]

COSTA, DP; BURNS, JM; CROCKER, DE; FEDAK, MA; TRUMBLE, S; GALES, N: Winter Foraging Ecology of Crabeater Seals The Antarctic marine environment undergoes considerable inter- and intra- annual variability, resulting in marked variation in the spatial and temporal availability of prey for vertebrate predators. Crabeater seals offer a unique opportunity to better understand the foraging […]

KROCHMAL, A.R.; BAKKEN, G.S.: Western Diamond-backed Rattlesnakes (Crotalus atrox) Use Their Facial Pits To Mediate Thermoregulatory Behavior Behavioral thermoregulation can impact foraging behavior, increase predation risk, and impart physiological costs. Locating thermally favorable microsites efficiently would minimize these constraints. Emitted thermal radiation is a direct indicator of an object’s surface temperature; using it as a […]

ANGILLETTA, M.J.*; PRINGLE, R.M.: Thermal Requirements of Offspring Drive the Nesting Behavior of Fence Lizards In squamate reptiles, thermal properties of nests have dramatic consequences for the survival and phenotypes of offspring. Optimal nest sites have been predicted from laboratory studies of the growth and survival of embryos, but tests of these predictions have been […]
