Meeting Abstract 55.1 Thursday, Jan. 6 The association between sex ratio, melanism and numerical abundance in mosquitofish HORTH, Lisa; Old Dominion University lhorth@odu.edu Male mosquitofish have two pigmented genotypes. The common morph is olivaceous gray and the rare morph is melanic (black spotted). Point mutations in genes associated with melanism, and with protein expression differences have been […]

RNA editing underlies temperature adaptation in K+ channels from polar octopuses
Meeting Abstract 55.4 Thursday, Jan. 5 RNA editing underlies temperature adaptation in K+ channels from polar octopuses GARRETT, Sandra/C*; ROSENTHAL, Joshua/JC; University of Puerto Rico, Institute of Neurobiology; University of Puerto Rico, Institute of Neurobiology sandracoralgarrett@gmail.com Early studies with squid giant axons showed that K+ channels, and the action potential phases they underlie, are especially temperature sensitive […]
FMRFamide Immunoreactivity and the Diffuse Nerve Net of Scyphozoan and Cubozoan Jellyfish
Meeting Abstract 55.1 Thursday, Jan. 5 FMRFamide Immunoreactivity and the Diffuse Nerve Net of Scyphozoan and Cubozoan Jellyfish SATTERLIE, Richard; University of North Carolina Wilmington satterlier@uncw.edu Two diffuse nerve nets have been described, morphologically and physiologically, in the subumbrella of scyphomedsuae. These nets have mostly parallel distributions, and both appear to influence the swim musculature. One, the […]

Why are muscle fibers so large Solving diffusion problems to attain maximal cell size
Meeting Abstract 55.6 Saturday, Jan. 5 Why are muscle fibers so large? Solving diffusion problems to attain maximal cell size KINSEY, S.T.; University of North Carolina Wilmington kinseys@uncw.edu Muscle fibers are among the largest cell types, but while diffusion appears to limit maximal fiber size, the selective pressures that control minimal size are unclear. During animal growth, […]
Risky Fats and Antioxidant Arsenals in Cold- and Warm-Bodied Fishes
Meeting Abstract 55.2 Saturday, Jan. 5 Risky Fats and Antioxidant Arsenals in Cold- and Warm-Bodied Fishes CROCKETT, E.L.; Ohio University crockett@ohiou.edu Fishes living at cold body temperatures are rich in biological membranes that are fortified with polyunsaturated fatty acids (PUFA). PUFA are particularly susceptible to lipid peroxidation, a process initiated by reactive oxygen species (ROS) and propagated […]
