The autosomal recessive mshi mutation in BALB/cBy mice phenotypically causes reduced testis size and male sterility in homozygotes. The development of the mshi male generative organs, prior to three weeks of age, appears to lack observable...
Phylogeography using nested clade analysis (NCA) is able to apply biological inferences to the history of populations of organisms independent of the population's structure. In the Western United States, phrynosomatine lizards have a complex...
Rats lacking normal hairy coats were discovered several years ago among our colony of hairy albino rats. The trait was found to be controlled by a recessive allele of a gene we designated shorn (shn), which mapped to distal end of rat chromosome 7....
Hermit crabs are marine crustaceans that must inhabit empty gastropod shells for shelter and protection from predation, desiccation and osmotic stress. In New England, the hermit crab (Pagurus longicarpus) commonly occupies two different types of...
Balanidae -- California -- San Diego; Seashore biology -- California -- San Diego; La Jolla (San Diego, Calif.)
Growth rates, mortality, and the total number of eggs of the intertidal acorn barnacle, Chthamalus fissus, were studied at La Jolla, California. Both mm and % (absolute and relative) growth rates compared to different body sizes were calculated...
Physical fitness for men -- Measurement; Energy metabolism -- Measurement; Vitamin D
Physical performance is related to functional disabilities. Better interventions to improve function may be targeted if the determinants of physical performance are understood. We evaluated predictors of performance. The relationship of physical...
Minor histocompatibility (H) antigens are typically identified as barriers to transplantation in graft exchange experiments between major histocompatibility complex (MHC)-matched hosts (Bailey 1975; Snell and Bunker 1960). This approach has allowed...
Competition has been demonstrated to be a major factor in the distribution and abundance of adult marine invertebrates. Although most marine invertebrates have complex life cycles that include larval stages, studies of interspecific competition...
Falkner Island, off the coast of Guilford, Connecticut, is the site of the largest breeding colony of endangered Roseate Terns (Sterna dougallii) and Common Terns (S. hirundo) in Connecticut, and the sixth largest colony of Roseate Terns in the...
Although many researchers have compared herpetofaunal assemblages over large geographical regions, comparisons on a microgeographic scale have been scarce. Thus, the goal of this study was to compare species diversity of Eleutherodactylus on a...
The intent of this research project was to purify the Shigella flexneri virulence plasmid without the use of ultra-centrifugation. The ultra-centrifugation is the most commonly used technique; however the PFGE has proven to isolate the plasmid...
Rocky intertidal organisms are distributed in zones characterized by a few dominant species of animals and plants. Physical and biological factors have effects on such a pattern of abundance. In addition, food selection and habitat complexity play...
Groundwater -- Connecticut -- Lieutenant River Watershed; Water quality -- Connecticut;
Water quality has become an important environmental issue as population growth and an expanded economy have caused increased degradation of many waterbodies. As a consequence of this degradation, stream characteristics are altered, habitats are...
Water quality monitoring stations -- Connecticut; Environmental monitoring -- Connecticut
Estuaries are rich in nutrients, such as nitrogen which may limit plant growth in coastal water bodies. Organic enrichment caused by allochthonous inputs of nitrogen has been shown to have adverse affects on water quality in estuaries. When...
The prophage of bacteriophage P1 is a unit copy plasmid, stable in Escherichia coli during cell division due to its partition system. The active P1 partition system consists of two genes, parA and parB, and a cis-site, parS. ParS contains all of...
Inhaled corticosteroids form the cornerstone of asthma treatment. They combat the inflammatory characteristics of asthma that result in bronchial hyperresponsiveness and overproduction of mucous. They do not have an immediate perceivable effect and...
The male sterility and histoincompatibility mutation (mshi) is an autosomal recessive mutation that produces apparently pleiotropic effects in mice. Mice homozygous for mshi manifest two distinct phenotypes. In both male and female mice, the...
Considering the pleiotropic manifestations of the rare, inherited, bone marrow failure disease, Fanconi Anemia, afflicted patients must be evaluated and monitored by specialty physicians (such as dermatologists, opthamologists, gastroenterologists,...
Botany -- Connecticut -- Branford (Town) -- Outer Island
The purpose of this study, on the Outer Island unit of the Stewart B. McKinney National Wildlife Refuge in Branford, CT, from July 1998 to June 1999, was to conduct botanical research and to make an associated collection of plant specimens. All...
The traprock ridge environments of Connecticut and Massachusetts are unique and little studied. This project examined the combination of tree and shrub species, their abundance, their dispersion pattern, and the pattern of succession on the Onion...
