NOTE: This download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Freshwater ecoregions provide a global biogeographic regionalization of the Earth's freshwater biodiversity. These units are distinguished by patterns of native fish distribution resulting from large-scale geoclimatic processes and evolutionary history. The freshwater ecoregion boundaries generally, though not always, correspond with those of watersheds. Within individual ecoregions there will be turnover of species, such as when moving up or down a river system, but taken as a whole an ecoregion will typically have a distinct evolutionary history and/or suite of ecological processes (Abell et al. 2008). The WWF defined...

Resilient stream systems are those that will support a full spectrum of biodiversity and maintain their functional integrity even as species compositions and hydrologic properties change in response to shifts in ambient conditions due to climate change. We examined all connected stream networks in the Northeast and Mid-Atlantic for seven characteristics correlated with resilience. These included four physical properties (network length, number of size classes, number of gradients classes and number of temperature classes), and three condition characteristics (risk of hydrologic alterations, natural cover in the floodplain, and amount of impervious surface in the watershed). A network was defined as a continuous...

The objective of this study was to provide a set of useful condition attributes for perennial stream and river segment in the northeast states (ME, NH, VT, MA, RI, CT, NY, PA, NJ, DE, MD, VA, WV, and DC.). Only perennial streams and rivers with catchments of one square mile or larger as mapped in the NHD Plus 1:100,000 Verson 1 dataset were included in this analysis because smaller streams were too inconsistently mapped. Stream and river reach flowlines were taken from the NHD Plus V1 1:100,000 dataset and tagged with geographic units (watersheds, states, ecoregions) and their simplified stream and river habitat types (23 types) as defined in the "Northeast Habitat Guides: A companion to the terrestrial and aquatic...

This dataset contains data collected within limestone cedar glades at Stones River National Battlefield (STRI) near Murfreesboro, Tennessee. This dataset contains information on soil microbial density (Most Probable Number of heterotrophic, culturable microbes per gram of soil) for soil samples obtained from certain quadrat locations (points) within 12 selected cedar glades. This information was obtained by performing a Plate Dilution Frequency Assay (PDFA) on a series of serial dilutions for each soil sample.For each quadrat location (point), one soil sample was obtained under sterile conditions, using a trowel wiped with methanol and rinsed with distilled water, and was placed into an autoclaved jar with a tight-fitting...

Note: The download link includes Fish Regions, Freshwater Ecoregions, and Freshwater Resilience. Within each freshwater ecoregion, we defined one to four discrete fish regions using a cluster analysis of the USGS 8-digit Hydrologic Units (HUC) based on similarities in their native fish composition. The analysis was based on a previously developed list of native species present within each HUC (NatureServe, 2008). The cluster analysis defined up to four clusters within each freshwater ecoregion using similarity of composition (Linkage method: Flexible beta, Distance measure: Sorensen (Bray-Curtis), Flexible beta value of -0.250). To determine the faunal distinctiveness between clusters, we performed an indicator...
