TRUEBLOOD, Lloyd A.*; SEIBEL, Brad A.; GILLY, William F.; University of Rhode Island; University of Rhode Island; Stanford University: Breath holding squid: Physiological constraints on vertical migrations of Dosidicus gigas Squids found in shallow waters have been shown to have high oxygen demands and limited oxygen transport capacity. As a result, such species are thought […]

Assessing changes in the pressure-area relationship in the open circulatory system of a decapod crustacean, Palaemonetes pugio in response to hypoxia
GUADAGNOLI, J. A.*; TOBITA, K.; REIBER, C.L.; Touro University – Nevada, Henderson; University of Pittsburgh, PA; University of Nevada, Las Vegas: Assessing changes in the pressure-area relationship in the open circulatory system of a decapod crustacean, Palaemonetes pugio in response to hypoxia. Cardiovascular changes during hypoxic exposure have been studied extensively in both vertebrate and […]
A Functional Interpretation of Pulmonary Structure in Marine Snakes
LILLYWHITE, H.*; SAWYER, W. G.; HEATWOLE, H.; Univ. of Florida, Gainesville; Univ. of Florida, Gainesville; North Carolina State Univ., Raleigh: A Functional Interpretation of Pulmonary Structure in Marine Snakes Snakes exhibit exceptional variation in pulmonary structure, related in part to demands of the gravitational environment. Terrestrial and especially arboreal species have short vascular segments, which […]
The effect of artificial loads on the straight flight performance of fruit bats
Meeting Abstract 39.3 Jan. 6 The effect of artificial loads on the straight flight performance of fruit bats IRIARTE-DIAZ, J.; Brown University jose_iriarte@brown.edu Most bats experience significant fluctuations in their body mass. These fluctuations can be both daily, mostly due to feeding, or seasonal due to fat storage and/or reproduction. Based on predictions derived from classic aerodynamic […]
The Scaling of Suction Feeding
Meeting Abstract 39.5 Jan. 6 The Scaling of Suction Feeding STAAB, KL*; SUMMERS, AP; STROTHER, JA; VAN WASSENBERGH, S; George Washington University; UC Irvine; UC Irvine; University of Antwerp, Belgium kstaab@gwu.edu We measured suction performance in a size series of great sculpin, Myoxocephalus polyacanthocephalus, to test hypotheses predicting the scaling of negative pressure. Two theoretical models of […]
Stretchy, sticky and strong evolution and ecology of spider capture fibers
Meeting Abstract 39.7 Jan. 6 Stretchy, sticky and strong: evolution and ecology of spider capture fibers SWANSON, B.O.*; HAYASHI, C.Y.; Gonzaga University; Univ. of California, Riverside swansonb@gonzaga.edu Spider silk provides an excellent model for examining connections between the properties of biological materials and organismal ecology. Orb-weaving spiders spin sticky capture threads that are made of exceptionally extensible […]
Scaling theory and locomotor performance the most speciose clade of birds fails to conform
Meeting Abstract 39.2 Jan. 6 Scaling theory and locomotor performance: the most speciose clade of birds fails to conform JACKSON, B.E.*; DIAL, K.P.; Univ. of Montana; Univ. of Montana brandon.jackson@mso.umt.edu Allometric predictions of locomotor performance are often based on the scaling of a few morphological or physiological variables and rarely validated by actual measurements of performance. The […]
Performance and niche space in a community of lizards
Meeting Abstract 39.9 Jan. 6 Performance and niche space in a community of lizards. MEYERS, J.J.*; IRSCHICK, D.J.; University of Massachusetts, Amherst; University of Massachusetts, Amherst meyerhoffer@gmail.com Studies examining niche relationships of lizard communities have focused primarily on spatial, temporal and trophic utilization of resources to explain niche partitioning. While ecomorphological work has established a strong link […]
Form Follows Function In Mode Of Attachment For Barnacles Commensal With Sea Turtles
Meeting Abstract 39.11 Jan. 6 Form Follows Function In Mode Of Attachment For Barnacles Commensal With Sea Turtles ZARDUS, J.D.*; BALAZS, G.H.; The Citadel, Charleston, SC; NOAA, National Marine Fisheries Service, Pacific Islands Fisheries Science Center, Honolulu, HI john.zardus@citadel.edu Approximately one dozen species of barnacles live attached exclusively to sea turtles. Yet, despite similarity of habitat they […]
Fiddler crab claws are both beautiful and powerful weapons a paradox resolved
Meeting Abstract 39.10 Jan. 6 Fiddler crab claws are both beautiful and powerful weapons: a paradox resolved CHRISTY, J. H.*; DENNENMOSER, S.; Smithsonian Tropical Research Institute christyj@si.edu Male fiddler crabs have one greatly enlarged claw that they wave to attract females for mating and that they use as a weapon to fight other males. Longer claws probably […]
