EDWARDS, D.D.; ERNSTING, B.R.; Univ. of Evansville; Univ. of Evansville: Determination Of Parentage And Kinship Relationships Among Symbiotic Water Mites Using RAPD-PCR Profiling The water mite Unionicola foili is a common symbiont of the freshwater mussel Utterbackia imbecillis. A female-biased sex ratio is characteristic of this species, with most mussels harboring a single male and […]

KEITH, B.A.*; GIBSON-BROWN, J.J.; Washington University in St. Louis; Washington University in St. Louis: Computational approaches to regulatory element identification: comparative analyses of the vertebrate Eomesodermin and T-brain T-box loci With the increasing realization that the evolution of developmental gene regulation is likely to be the driving force in the evolution of novel morphologies, the […]

WILLIAMS, K.L.; Texas A&M University: Color complexity in the dactyls of the blue crab, Callinectes sapidus: a new method to evaluate biologically significant characteristics. Many species use color during courtship displays, with the more colorful individuals often selected as potential mates. Studies of mate choice have typically viewed multi-colored attributes as a single homogenous color, […]

ELLINGTON, W.R.; Florida State Univ.: Cloning and Expression of a Polychaete Glycocyamine Kinase Glycocyamine (guanidinoacetate) is the direct precursor of creatine, the guanidine substrate for the creatine kinase (CK) reaction. In many species of errant polychaetes (Nereidae, Nephthydidae, Aphroditidae) glycocyamine is present at high tissue levels. However, this compound is not methylated to form creatine […]

L.; Colorado State University; Colorado State University; Bodega Marine Laboratory; Colorado State University: Cloning and Expression of Lobster Calcineurin A Calcineurin is a Ca2+-activated protein phosphatase involved in Ca2+-dependent signal transduction in various tissues; known targets are histones, myosin light chain, cAMP-dependent protein kinase, and transcription […]

LOVETT, D.L.*; RICART, T.M.; TANNER, C.A.; TOWLE, D.W.; The College of New Jersey, Ewing; Mt. Desert Island Biol. Lab., ME: Chronic exposure of the blue crab, Callinectes sapidus, to low salinity stimulates expression of Na+,K+-ATPase α-subunit mRNA and protein in gills When estuarine crabs are transferred from high to low salinity, the specific activity of […]

LARSON, P.M.*; DE S�, R.O.; ARRIETA, D.; Ohio University; University of Richmond; Montevideo, Uruguay: Chondrocranial, hyobranchial, and internal oral morphology in the basal bufonid genus Melanophryniscus (Amphibia: Anura) Melanophryniscus is a genus of small toads inhabiting the southern portion of South America. This genus is considered basal within the family Bufonidae. Data on larval chondrocranial […]

KIM, Hyun Woo; YU, Xiaoli ; MYKLES, donald L; Colorado State University: Characterization of cDNAs encoding decapod crustacean calpains Calpains constitute a large and diverse family of Ca2+-dependent cysteine proteinases in animal cells. In decapod crustaceans, four calpain activities mediate molt-induced claw muscle atrophy. Selective degradation of myofibrillar proteins reduces muscle mass so that the […]
