THOMASON, KL; TOWLE, DW; HENRY, RP; Auburn Univ.; Mt. Desert Island Biol. Lab.; Aburn Univ.: Quantitative expression of carbonic anhydrase mRNA in the gills of Carcinus maenas during acclimation from high to low salinity Carbonic anhydrase (CA) activity is known to be induced up to 12 fold in the posterior, ion transporting gills of the […]

COVI, JA; HAND, SC; Louisiana State University: Protein evidence for V-ATPase expression in Artemia franciscana gastrulae: Potential role in anoxia signaling. Under anoxia, embryos of A. franciscana exhibit severe metabolic depression as they approach a state that is nearly ametabolic. For over 20 years it has been known that this state is accompanied by an […]

COLLETTE, M.; ANCTIL, M.; Univ. de Montr�al, Montr�al: Presence of estrogen receptor-like immunoreactivities in the cnidarian Renilla koellikeri Steroid hormones such as estrogens were recently reported in the sea pansy, Renilla koellikeri, and in other anthozoans (corals). Although a role for estrogens in the reproduction of the sea pansy and of scleractinian corals has been […]

WUNDERLICH, R.E.*; SINOPOLI, M.C.; KILKENNY, P.; James Madison University: Plantar pressure distribution during bipedalism in Propithecus verreauxi Propithecus verreauxi, an indrid primate specialized for vertical clinging and leaping (VCL), exclusively uses bipedalism during terrestrial locomotion. They use a unique galloping bipedal gait with lead and trail limbs switching every 5-7 steps. Whereas the human foot, […]

MONETTE, M.Y.*; MCCORMICK, S.D.; University of Massachusetts, Amherst; Conte Anadromous Fish Research Center, USGS: Physiological and endocrine mechanisms of acid/aluminum impacts on Atlantic salmon smolt development Many rivers and streams in eastern North America and northern Europe experience episodic pulses of acidity due to anthropogenic acidification. These pulses combined with low buffering capacity of soils, […]

FANGUE, N.A.*; SCHULTE, P.M.; University of British Columbia; University of British Columbia: Performance as a Function of Temperature in Two Subspecies of Fundulus heteroclitus Fundulus heteroclitus inhabits inshore bays and estuaries along the North American East Coast. At the extremes of the species� range, northern mummichogs, F.h.macrolepidotus, and southern mummichogs, F.h.heteroclitus, are exposed to substantially […]

MCFADDEN, A; THURMAN, C.L.*; University of Northern Iowa: Osmoregulation by Fiddler Crabs (genus Uca) from California and south Florida Nine species of fiddler crabs belonging to three subgenera (Boboruca, Celuca and Minuca) were collected for osmoregulation studies from 38 locations in south Florida as well as one site at Mission Bay in California. The Celuca […]
