On Two North American Philotarsids (Psocoptera)

Comparative phylogeography of two North American 'glacial relict' crustaceans.

The Pleistocene glaciations represent the most recent and dramatic series of habitat changes since the Cretaceous. The impact of these events was particularly acute for aquatic taxa with poor powers of dispersal, but few organisms have evolutionary histories more intimately entwined with the advance and retreat of ice than the 'glacial relicts'. In this study, we used a mitochondrial gene, cyto...

North American blastomycosis.

N ORTH American blastomycosis (Gilchrist’s disease) is a granulomatous, infectious disease caused by the fungus, Blastomyces dermatitidis (Gilchrist and Stokes, 1898). The malady, in its cutaneous form, was first described by Gilchrist’ in 1894. A few years later, together with Stokes, he was able to isolate and culture the causative organism which he designated as B. dermatitibis.23 The first ...

North American Logistics

Globalization induces the transport sector and supply chains to adapt to new functional and operational considerations. This is particularly the case for North America because of the geographical scale and scope of its production, distribution and consumption activities (Brooks, 2008; Rodrigue and Hesse, 2007). In a context where transport technology such as containerization has been a powerful...

North American Fungi

Morphological and molecular characteristics support the recognition of a welldefined taxonomic group within the Entolomataceae. The distinctive basidiospore form and a three locus DNA analysis separate the species that share these characteristics from other species of Entoloma s. l. We propose here a new genus, Entocybe, to accommodate these taxa.
