The identity of Cintractia carpophila var. kenaica: reclassification of a North American smut on Carex micropoda as a distinct species of Anthracoidea
Cintractia carpophila var. kenaica, a neglected taxon described from Alaska more than half a century ago, is re-described and illustrated. Its nomenclature and taxonomic status are discussed. This smut species is characterised by small spores with a very finely verruculose surface rarely enclosed by a thin, hyaline, mucilaginous sheath, a wall with 2-5 distinct internal swellings, and parasitis...

متن کاملCorrelates of species richness in North American bat families
Aim A near universal truth in North America is that species richness increases from the Arctic Circle to the Central American tropics. Latitude is regarded as a major explanatory variable in species density, although it is only a surrogate for underlying ecological variables. I aimed to elucidate those underlying ecological variables that are associated with variation in bat species richness ac...
متن کاملDiscussion of Related Species in North American Canids and Mustelids
Specimens of Filaroides milksi Whitlock, 1956 removed from the same lung tissue as were the type specimens were re-examined. Because of morphological features similar to those found in the genus Andersonstrongylus Webster, 1978 and inconsistent with those in Filaroides van Beneden, 1850, F. milksi is removed from the latter and placed in Andersonstrongylus as A. milksi (Whitlock, 1956). All ava...
متن کاملInvasion of North American drainages by alien fish species
1. Data from the literature were used to document colonization patterns by introduced freshwater fishes in 125 drainages across temperate North America. We analysed this data set to quantify susceptibility to invasion, success of the invaders and changes in species richness. 2. Drainages with a high number of impoundments, large basin area and low native species diversity had the greatest numbe...
