Our objective was to reexamine the definition and use of surrogates in biodiversity studies of disturbed ecological communities. To this end, we examined diversity and community structure in recovering (pollution damaged) and restored (via lining, fertilizing, seeding, and planting) forests in the Great Lakes-St. Lawrence zone near Sudbury Ontario, Canada. The relationships among taxonomic groups were determined using correlations between Shannon diversity and species richness. We used correspondence analysis to quantify the contribution, of taxonomic groups to diversity and community structure. We detected useful surrogates in the naturally recovering forests but not in restored forests. In the former, vascular...
This U.S. Geological Survey (USGS) Data Release provides periphyton data collected from 20 sites in Johnson County, Kansas, during April 2010. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS research efforts and publications available to the public. The dataset includes samples collected at 20 USGS sample locations in Johnson County, Kansas. Periphyton were identified to the lowest possible taxonomic level and abundance (density) and biovolume are reported.
The Eastern Brown Pelican (Pelecanus occidentalis carolinensis) is a large-bodied seabird that nests in colonies of 10 to upwards of 5,000 pairs, on nearshore islands in subtropical and tropical North American waters. It breeds between March and August, laying 2–3 eggs and raising 1–2 chicks per year. The species is facultatively migratory during nonbreeding, with some individuals remaining resident and others leaving breeding areas. Pelicans forage in near- and offshore waters and capture schooling fish by plunge-diving. This dataset summarizes taxonomical information for all prey species identified in the diet of Brown Pelican collected in 2013-2015 at 10 breeding colonies in the northern Gulf of Mexico from...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from the Kansas River and tributaries, during July 2012 through February 2017. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS research efforts and publications available to the public. The dataset includes all routine and quality assurance/quality control samples collected at two locations along the Kansas River (USGS station numbers 06887500, 06892350) and three tributary sites (USGS station numbers 06857100, 06887000, 06890900). Phytoplankton were...

The Holarctic Archips xylosteana Group consists of at least 18 morphologically similar species in the Nearctic, three of which were synonymized with A. argyrospila by Razowski and subsequently returned to species status, two that were described since 1986 but are clearly related to A. argyrospila , and an additional Western clade of A. argyrospila haplotypes that Razowski had not seen. We examined the morphology of all described Nearctic Xylosteana Group members plus one undescribed species, as well as DNA variation in a 816 bp segment of the mitochondrial COI gene for 17 of these species. We also examined three of five species of Archips from the Packardiana Group (=Archippus Freeman), and three outgroup genera...
