متن کاملPatterns of range-wide genetic variation in six North American bumble bee (Apidae: Bombus) species.
The increasing evidence for population declines in bumble bee (Bombus) species worldwide has accelerated research efforts to explain losses in these important pollinators. In North America, a number of once widespread Bombus species have suffered serious reductions in range and abundance, although other species remain healthy. To examine whether declining and stable species exhibit different le...
متن کاملRecent range expansion and divergence among North American Prairie Grouse.
Prairie grouse (genus: Tympanuchus) once existed throughout much of North America but have recently experienced significant population declines, isolation, and extinction. In previous molecular studies, contrasting patterns or an unresolved polytomy among Tympanuchus taxa (Tympanuchus phasianellus, Tympanuchus pallidicinctus, and Tympanuchus cupido) have resulted from traditional phylogenetic m...
متن کاملTaxonomic review and phylogenetic analysis of fifteen North American Entomobrya (Collembola, Entomobryidae), including four new species
The chaetotaxy of 15 species of eastern North American Entomobrya is redescribed in order to determine potential characters for the diagnosis of cryptic lineages and evaluate the diagnostic and phylogenetic utility of chaetotaxy. As a result, four new species (Entomobrya citrensis Katz & Soto-Adames, sp. n., Entomobrya jubata Katz & Soto-Adames, sp. n., Entomobrya neotenica Katz & Soto-Adames, ...
