Data from: Which specimens from a museum collection will yield DNA barcodes? A time series study of spiders in alcohol

Jeremy A. Miller, Kevin K. Beentjes, Peter Van Helsdingen, Steven Ijland & Jeremy Miller
We report initial results from an ongoing effort to build a library of DNA barcode sequences for Dutch spiders and investigate the utility of museum collections as a source of specimens for barcoding spiders. Source material for the library comes from a combination of specimens freshly collected in the field specifically for this project and museum specimens collected in the past. For the museum specimens, we focus on 31 species that have been frequently collected...

Data from: Biogeography of scorpions in the Pseudouroctonus minimus complex (Vaejovidae) from south-western North America: implications of ecological specialization for pre-Quaternary diversification

Robert W. Bryson, Warren E. Savary & Lorenzo Prendini
Aim: The aim of this study was to assess the impact of pre-Quaternary tectonics and orogeny relative to that of Pleistocene climate change on diversification within the Pseudouroctonus minimus complex, a group of vaejovid scorpions with stenotopic habitat requirements. Location: South-western North America (United States and Mexico). Methods: Multilocus sequence data (1899 base pairs from two mitochondrial and two nuclear genes) were generated from 65 samples of scorpions in the minimus complex. Phylogeographical structure within...

Data from: Brazilian marsupial frogs are diphyletic (Anura: Hemiphractidae: Gastrotheca)

David C. Blackburn & William E. Duellman
Molecular phylogenetic analyses based on expanded taxonomic and geographic sampling support the monophyly of the marsupial frog genera (family Hemiphractidae), resolve six geographically circumscribed lineages within Gastrotheca, and, for the first time, reveal that two divergent lineages of Gastrotheca inhabit the Atlantic Coastal Forests of Brazil. Within Gastrotheca, the earliest diverging clade is confined to northeastern Brazil, whereas the three subsequent diverging lineages are restricted to northern Venezuela (G. walkeri), southeastern Brazil, and northwestern South...
