LOKE, Kerri; BERNAL, Diego; Saddleback College; Weber State University: Salinity induced stress-response in trout blood Rainbow trout, Oncorhynchus mykiss, have the ability to migrate over prolonged periods of time (i.e., weeks to months) between freshwater and marine environments. However, in freshwater trout aquaculture, fishes may be exposed to immersions in saline water (10-15 ppt) for […]

LIGHT, D.B.; HELM, E.M.; MASON, L.Z.; SHELLY, J.L.; Lake Forest College; Lake Forest College; Lake Forest College; Lake Forest College: Regulated Volume Decrease in Salmo salar Erythrocytes Salmo salar (Atlantic salmon) is an anadromous euryhaline teleost whose gills are exposed to a wide range of salinities during its life cycle. With this in mind, we […]

SIKES, J.M.*; BELY, A.E.; University of Maryland, College Park; University of Maryland, College Park: Regeneration and asexual reproduction in acoels of the genus Convolutriloba Acoels in the genus Convolutriloba display remarkably different forms of asexual reproduction and possess amazing capacities for regeneration. While C. hastifera reproduces by simple transverse fission followed by regeneration, the closely […]

JAYASUNDARA, N.*; SPANINGS-PIERROT, C.; TOWLE, D.W.; College of the Atlantic; Universite Montpellier II; Mount Desert Island Biological Laboratory: Quantitative analysis of hsp70 mRNA expression under salinity stress in the euryhaline shore crab Pachygrapsus marmoratus Marbled rock crabs (Pachygrapsus marmoratus) are subjected to physiological stress due to large and rapid fluctuations in seawater salinity, conditions that […]

MCGAW, IJ; University of Nevada, Las Vegas: Prioritization or summation of events? Physiological responses of postprandial Dungeness crabs in low salinity The Dungeness crab, Cancer magister, inhabits sandy bays and estuaries and is classed as a weak osmoregulator. During exposure to low salinity the crabs reacted with an increase in heart rate, but a large […]

GAINEY, L.F. , Jr.; GREENBERG, M.J.; Univ. of Southern Maine, Portland; C.V. Whitney Lab., Univ. of Florida, St. Augustine.: Potentiation of branchial muscle contraction in bivalve molluscs Previously, we found that when isolated gills of Mercenaria mercenaria are treated with 5-hydroxytryptamine (5HT), the branchial musculature contracts. Moreover, a second application of the same concentration of […]

FORD, D.K.*; HOLLIDAY, C.M.; Ohio University, Athens, OH; Ohio University, Athens, OH: PCB 126 has detrimental effects on bone density in juvenile diamondback terrapins Synthetic organochlorines, such as polychlorinated biphenyls (PCBs), have been detected in all biological matrices (e.g. air, soil, water, tissue) on every continent. PCB 126 is an endocrine-disrupting toxin with estrogenic effects […]

SARKAR, Soma; MCCALL, R. Dale; KINSEY, Stephen T.; Univ. of North Carolina at Wilmington; Univ. of North Carolina at Wilmington; Univ. of North Carolina at Wilmington: Oxygen consumption in mice with inherited hypoxic exercise tolerance Oxygen consumption (VO2) was determined during hypoxic exercise after acclimation to normoxia or hypoxia in three inbred strains of mice.
