Mammal species richness and biogeographic structure at the southern boundaries of the Nearctic region

Mammalia, 2014
AbstractWe analyzed whether the spatial variation in mammal species richness reflects the southern boundaries of the Nearctic region as previously established by endemism patterns. Records from 710 mammal species were drawn on a map of North America (from Canada and Alaska to Panama) gridded at 4° latitude-longitude. We evaluated the probable existence

An analysis of species boundaries and biogeographic patterns in a cryptic species complex: The rotifer—Brachionus plicatilis

Molecular Phylogenetics and Evolution, 2006
Since the advent of molecular phylogenetics, there is increasing evidence that many small aquatic and marine invertebrates--once believed to be single, cosmopolitan species--are in fact cryptic species complexes. Although the application of the biological species concept is central to the identification of species boundaries in these cryptic complexes,

Urban ecosystems as ‘natural’ homes for biogeographical boundary crossings

Transactions of the Institute of British Geographers, 2011
Urban ecosystems have long been neglected in ecological theory and urban politics, with their respective tendencies towards anti-urbanism and exclusive humanism. As Hinchliffe et al. argue, ‘not pure enough to be true and not human enough to be political, urban wilds have no constituency’ (2005, 645).

A Biogeographical Boundary: The Tatschl Line

Transactions of the Kansas Academy of Science (1903-), 1970
Every now and then a discovery is made, either by design, resulting from careful observations, or else incidentally to other studies, not to say accidentally. Thus biogeographers are acquainted with the Wallace Line. Wallace's keen observations led him to conclude that there is a line passing through the Lombok and Makassar Straits, east of Bali and ...
