Shreve, S.M.*; Kelty, J.D; Lee, R.E.: The Preservation of Reproductive Behaviors during Chilling by a Rapid Cold-Hardening Process in Drosophila melanogaster Rapid cold-hardening, which occurs within minutes or hours, confers protection from injury during sudden chilling. Recently, we demonstrated that rapid cold-hardening occurs during ecologically-based thermoperiods and functions to decrease the temperature at which flies […]

CUNNINGHAM, S.L.*; MARIS, R.C.: The Employment of Mini-Biocells for the Bioremediation of Petroleum-Contaminated Soil over a Two-Week Period The potential of petroleum spills possesses a significant threat to the natural environment. Such eminences have prompted the necessity for alternative methods of contaminated soil treatment. Studies at Mansfield University, over the last seven years, have centered […]

B.H. JENSEN*; M.H. TAYLOR: The Effects of Estradiol Implants on Lipid Transport in Fundulus heteroclitus Fundulus heteroclitus (mummichog) is a euryhaline teleost that is common along the western Atlantic coast from the maritime provinces to Florida. This species has a semilunar reproductive cycle that is accompanied by large changes in plasma levels of triglycerides, the […]

MEYER, H.A.: Tardigrada of Arkansas and Louisiana Outside of the states of Texas and Alabama, the distribution of limnoterrestrial tardigrades in the American Deep South is poorly known. There are no published records from the states of Louisiana and Mississippi, while in Arkansas only one species has been reported. As part of a long-term study […]

BELDEN, L.K.*; MOORE, I.T.; BLAUSTEIN, A.R.: Survival and the physiological stress response in Cascades frog tadpoles exposed to ambient UV-B radiation in the field Global environmental changes, including increases in ultraviolet-B radiation (UV-B; 280-320 nm), are receiving attention from biologists interested in how these changes will alter community and ecosystem structure and function. However, we […]

HENRY, R.P.: Suppression of salinity-sensitive branchial carbonic anhydrase induction by a compound in the eyestalk of the euryhaline green crab, Carcinus maenas. Carbonic anhydrase activity in the posterior gills of the euryhaline green crab, Carcinus maenas, undergoes an 8 fold induction upon transfer from 32 to 12 ppt salinity. Eyestalk ablation (ESA) results in a […]

DOELLER, J.E.*; KRAUS, D.W.: Sulfide-mediated feedback inhibition of endogenous substrate oxidation in Geukensia demissa gill mitochondria? Gill mitochondria from Geukensia demissa, a marine mussel from high sulfide sediments, exhibit sulfide-supported respiration with an ADP/O ratio near one. In vivo, sulfide-mediated gill oxygen consumption is three times higher than control at the same ciliary beat frequency, […]

Quinn, N.J.*; Newell, P.: Subsurface sea water temperatures and the year 2000 coral bleaching event in Fijian waters Analysis of three years of subsurface sea water temperatures at several sites shows increased temperatures receeding the year 2000 coral bleaching event. Hugrun automated temperaure recorders were deployed at 3m at twelve sites and programed to record […]

TYLER, S.*; HOOGE M.D.: Squeezing through tight spaces–functional morphology of musculature of Gnathostomula armata Gnathostomulids live in fine-grained sediments with pore sizes that are typically smaller than the diameter of their bodies. How they negotiate such spaces is something of a mystery, but whole-mount preparations of Gnathostomula armata stained with a phalloidin-linked fluorescent marker to […]

NORDEEN, J.M.*; SHEFFIELD, E.M.; KINSEY, S.T.: Size- and salinity-dependent enzyme activities in gills of the blue crab In the lower Cape Fear River estuary, populations of juvenile (< 12 mm carapace width) blue crabs, Callinectes sapidus, are found at low salinity (
