Phrynosomatid Lizards Show Parallel Variation in Sprint Speed and Muscle Fiber-Type Properties

BONINE, K.E.*; GLEESON, T.T.; GARLAND, T. Jr.: Phrynosomatid Lizards Show Parallel Variation in Sprint Speed and Muscle Fiber-Type Properties Phrynosomatids are comprised of 3 distinct subclades ((sand lizards, horned lizards), Sceloporus group)) that exhibit great variation in habitat, behavior, and general body plan. This family also varies widely in maximal sprint speed; sand lizards are […]

Patterns of protein expression in zebrafish muscle during hypoxia

BOSWORTH, C.A.*; REES, B.B.: Patterns of protein expression in zebrafish muscle during hypoxia Alterations of protein expression may be important in determining the capacity of an organism to tolerate low oxygen concentrations. Most previous studies of fish exposed to hypoxia have examined changes in individual proteins. Here, we report on the use of two-dimensional electrophoresis […]

Partial purification of a postmolt cuticular glycosidase from Callinectes sapidus and its putative role in mineralization

HALBROOK, K.E.*; ROER, R.D.; SHAFER, T.H.; PIERCE, D.C.; BUTLER, K.D.: Partial purification of a postmolt cuticular glycosidase from Callinectes sapidus and its putative role in mineralization We have previously demonstrated a marked change in sugar moieties of glycoproteins of the cuticle of the blue crab, Callinectes sapidus, between 0.5 and 3 h postecdysis. The present […]

Overwintering strategies of the wood frog, Rana sylvatica, in interior Alaska

Middle, L.B.*; Barnes, B.M: Overwintering strategies of the wood frog, Rana sylvatica, in interior Alaska The wood frog, Rana sylvatica, is one of the most northerly distributed amphibian species with populations ranging up to 100 miles north of the Arctic Circle. The key to its survival at high latitudes is the ability to survive extracellular […]

Overwintering Energetics of the Red-backed Salamander, Plethodon cinereus

Christman, T.M.*; Finkler, M.S.: Overwintering Energetics of the Red-backed Salamander, Plethodon cinereus. Red-backed salamanders are known to actively forage during the winter. The present study examined the importance of successful foraging to the overall energy budget during overwintering. We measured oxygen consumption rate and whole-body triglyceride and glycogen contents before and after a five-month overwintering […]

Osmotic and ionic regulation in the hydrothermal vent crab Bythograea thermydron

MARTINEZ, A.-S.; TOULLEC, J.-Y.; SHILLITO, B.; CHARMANTIER-DAURES, M. *; CHARMANTIER, G.: Osmotic and ionic regulation in the hydrothermal vent crab Bythograea thermydron This study investigates the salinity tolerance and the ability to osmoregulate and ionoregulate of a brachyuran crab endemic to the deep sea hydrothermal vent habitat, Bythograea thermydron. Crabs were collected during the HOPE […]

New Sticky Things in Holopelagic Nemerteans

NORENBURG, J.L.*; ROE, P.: New Sticky Things in Holopelagic Nemerteans Biology and diversity of delicate, gelatinous, holopelagic deep-sea organisms continue to be sources of major surprises, despite more than a century of studies. Nemerteans are among the least studied groups of these organisms. Recent collaborative deep-sea mid-water collections made with J. Childress (UCSB) and Monterey […]

Na,K-ATPase in gills of the blue crab Callinectes sapidus cDNA sequencing and salinity-related expression of ALPHA subunit mRNA and protein

PAULSEN, R.S.*; WEIHRAUCH, D.; LIGNOT, J.-H.; TOWLE, D.W.: Na,K-ATPase in gills of the blue crab Callinectes sapidus: cDNA sequencing and salinity-related expression of ALPHA subunit mRNA and protein. Many studies have shown that hyperosmoregulation in euryhaline crabs is accompanied by enhanced Na,K-ATPase activity in posterior gills, but it is not clear whether the response is […]

Morphological and immunochemical properties of the urinary bladder in female Atlantic stingrays (Dasyatis sabina)

Piermarini, P.M.*; Choe, K.P.; Evans, D.H.: Morphological and immunochemical properties of the urinary bladder in female Atlantic stingrays (Dasyatis sabina) In vertebrates, urinary bladders serve as temporary storage organs for urine produced by the kidneys. Additionally, bladders are able to attenuate the final pH and ionic concentrations of urine before it is excreted. In elasmobranch […]

Modulating Mitochondrial Transcription in Artemia franciscana Embryos

EADS, B.D.*; HAND, S.C.: Modulating Mitochondrial Transcription in Artemia franciscana Embryos Gastrula stage embryos of the brine shrimp Artemia franciscana exhibit developmental and metabolic arrest in response to adverse environmental conditions such as anoxia. This arrest is coordinated and profound, indicating a high degree of control at the level of gene expression. Previous studies have […]
