HENRY, M.: Modeling Body Temperature of Intertidal Snails: Hot Mud and Hot Bodies Intertidal snails face a cyclical ambient environmental regime due in part to the tides. However, do their body temperatures change along with the ambient environment or do they act as biological filters, not being affected by factors like the drastic temperature change […]

YIN, M.*; YANCEY, P.H.: Methylamine Osmolytes Dominate in Deep-Sea Polychaetes, Pycnogonids, and Octopods Osmolytes of shallow-water marine invertebrates are usually free amino acids such as glycine, alanine, taurine. Recently we showed that some deep-sea crustaceans and molluscs are dominated by trimethylamine oxide, which can offset inhibition by pressure. Echinoderms and gastropods were dominated by scyllo-inositol, […]

HOFER, S.C.*; DRACKETT, M.; WATTS, S.A.: Low temperature tolerance of GMTTM tilapia,Oreochromis niloticus. Genetically male tilapia (GMTTM) are produced by crossing XX female and YY male broodstock. They exhibit hybrid vigor with increased growth rates and are favored for aquaculture in warm climates. In the US tilapia fingerlings are cultured at hatcheries and are reared […]

BEAULIEU, L.; ALLEN, S.; BURNETT, K.; BURNETT, L.*: Low pH Effects on the Killing Activity of Oyster Hemocytes An assay was used to measure the ability of hemocytes of the Eastern oyster, Crassostrea virginica to kill the bacterium Vibrio parahaemolyticus. Experiments were carried out at pH 7.6 and 6.6 mimicking the in vivo hemolymph environment […]

GORDON, S.D.*; STEVENSON, R: Long-term Mass Gains relative to Meal Size and Sugar Concentration in Two Species of Butterflies, Pieris rapae and Manataria maculata We investigated how the concentration of sugar in artificial nectar affects meal size and changes in body mass of Pieris rapae, a widely dispersed common Pierid species captured in Boston, MA […]

JENKINS, J.L.*; SWANSON, D.L.: Liver Glycogen and Freezing Survival in the Chorus Frog (Pseudacris triseriata). In freeze tolerant frogs, a principal component of freezing survival is the production and distribution of cryoprotectants (glucose or glycerol) from liver glycogen stores. The size of these stores limits the absolute amount of cryoprotectant produced during a freezing bout, […]

PREEST, M.*; GONZALEZ, R.: Ion Balance in the Extremely Acid-Tolerant Neon Tetra Neon tetras (Paracheirodon innesi) are native to acidic waters of the Amazon. They are highly acid-tolerant and survive exposure to acidity levels that are lethal to many species due to a disruption of ion fluxes, particularly Na+. Uptake of Na+ in neon tetras […]

DOUGHERTY, B.E*; MCNAMER, A.N.; CROCKETT, E.L.: Inverse Compensation for Fluidity in Mitochondrial Membranes from Thermally Acclimated Earthworms Exposure to low temperature typically results in changes at many levels of biological organization including adjustments in both chemical and physical properties of biological membranes. We compare membrane fluidities in enriched mitochondrial preparations from the body wall of […]

CIURA, S.M.; BIBEAU, M.R.; SCHULTE, P.M.*: Intraspecific variation in heat shock proteins and thermal tolerance Populations of Fundulus heteroclitus are distributed through a thermal cline along the Atlantic Coast of North America, from Newfoundland to Florida. At the northern end of the species range, fish experience average annual temperatures ~12 degrees cooler than their southern […]

GALE,H.H.: Intermittent breathing in very large mammals. Breath holding is common in reptiles. Intermittent breathing also occurs in very large mammals; whale, elephant, rhinoceros, hippopotamus, and giraffe. Both groups have low rates of metabolism. Ectothermy allows the low rates of reptiles. Endotherms have higher metabolic rates that are inversely related to body size. Hence the […]
