Homologs of genes and anonymous loci on human Chromosome 13 map to mouse Chromosomes 8 and 14
(Springer-Verlag, 1995-04)
To enhance the comparative map for human Chromosome (Chr) 13, we identified clones for human genes and anonymous loci that cross-hybridized with their mouse homologs and then used linkage crosses for mapping. Of the clones ...
Postnatal ontogeny of acetylated and non-acetylated B-endorphin in rat pituitary
(Elsevier, 1983)
Extracts of the anterior lobe and intermediate lobe of postnatal (P) (Day P1, P7, P14, P21, P28, P35, P42) and adult male Spraque-Dawley rats were analyzed by both a Beta-endorphin (B-END) radioimmunoassay and a radioimmunoassay ...

Stress in biological invasions: Introduced invasive grey squirrels increase physiological stress in native Eurasian red squirrels
(European Squirrel InitiativeWiley Periodicals, Inc., 2018-09)
Invasive alien species can cause extinction of native species through processes including predation, interspecific competition for resources or disease‐mediated competition. Increases in stress hormones in vertebrates may ...
Individual and population sex allocation patterns
(Elsevier, 1987-02)
A variety of sex allocation models is considered in which (i) the reproductive returns on investment in males differ from the returns on investment in females, (ii) the amounts of resources available for reproduction vary ...
Nutrient availability and invasive fish jointly drive community dynamics in an experimental aquatic system
(US Fish and Wildlife ServiceWiley Periodicals, Inc., 2018-03)
Species invasions increasingly occur alongside other forms of ecosystem change, highlighting the need to understand how invasion outcomes are influenced by environmental factors. Within freshwaters, two of the most widespread ...
There is no support for Jensen's hypothesis of nemerteans as ancestors to the vertebrates
(Kluwer Academic Publishers; Springer Science+Business Media, 1997-01)
Nemerteans (phylum Nemertea) have been viewed by mostzoologists as descended from, or closely related to,the flatworms. This view is based mainly on theirsupposedly acoelomate body. Their ancestry, however,is a point of ...
Anthropogenic nitrogen deposition ameliorates the decline in tree growth caused by a drier climate
(Cambridge University PressWiley Periodicals, Inc., 2018-02)
Most forest ecosystems are simultaneously affected by concurrent global change drivers. However, when assessing these effects, studies have mainly focused on the responses to single factors and have rarely evaluated the ...
Identification and characterization of a human transthyretin variant
(Elsevier, 1987-10-14)
An apparent Mr variant of plasma transthyretin (TTR), previously detected using 2-D PAGE, is the first reported occurrence of this type of human TTR variant. We characterized the variant TTR to determine the nature of this ...
