We have explored the possible mechanisms by which mineralocorticoid (MR) and glucocorticoid (GR) receptors regulate the response to freshwater transfer in the gills of the euryhaline killifish Fundulus heteroclitus. Killifish were implanted with RU486 (GR antagonist) or spironolactone (MR antagonist) at doses of 0.1–1.0 mg g−1, and subsequently transferred(More)
The structure, regulation and evolution of the cystic fibrosis transmembrane conductance regulator (CFTR) gene were characterized in common killifish (Fundulus heteroclitus). Killifish CFTR (kfCFTR) structure was conserved with other CFTR homologues, but was more compact than those of mammals. A motif in intron 1 was conserved across all teleost CFTR(More)
PREMISE OF THE STUDY Genetic knowledge is completely lacking for Pacific dogwood (Cornus nuttallii), a western North American temperate tree that is pollinated and dispersed by biological vectors. We investigated how history, geography, and climate have affected population genetic structure, local adaptation, and the phylogeography of this species. (More)
