Hydrospatial Framework for the Laurentian Great Lakes

This data release provides the georeferenced boundaries that delimit each spatial unit of the Great Lakes Regional Aquatic Gap Analysis Project (GLGap) Coastal Hydrospatial Framework at each spatial scale from the local 90m cell to the entire Laurentian Great Lakes system and from the shoreline to the deepest offshore waters. The U.S. Geological Survey and the U.S. Fish and Wildlife Service collaborated to design a universal framework of spatial areas that encompass all space of the Laurentian Great Lakes proper. Agglomeration of the finest units (90m cells) form coarser, broader scale units. Finer units are nested within the coarser units at six spatial scales, labeled as Local Cells, Aquatic Habitat Areas, Coastal...

Taxonomic composition of environmental DNA acquired by filtration from the St. Regis River, New York

Environmental DNA (eDNA) surveys have become important tools for monitoring aquatic biodiversity. Barcode sequencing of eDNA generates community profiles that, while potentially biased in both capture and amplification, can nonetheless yield high information content per unit cost. While factors affecting eDNA capture and amplification have been heavily studied, watershed-scale assessments of fish communities and our confidence in such have been less frequent. We performed an initial watershed-scale characterization of fish eDNA using rapid, low-volume filtering with replicate and control samples scaled for a single Illumina MiSeq flow cell, using the mitochondrial 12S ribosomal RNA locus for taxonomic profiling....

Abiotic data collected in the St. Lawrence River and several tributaries in and adjacent to the Saint Regis Mohawk Tribe reservation in northern New York, 2004

This data set includes the sample site locations, site descriptions, and abiotic data used in the analyses reported in McKenna et al. 2008. The data represent selected abiotic conditions within the St. Lawrence and lower reaches of four US tributaries during 2004. Samples were collected from shallow, seinable areas (< 1.5 m) of the St. Lawrence River, adjacent wetland channels, and the lower reaches of major tributaries (Grass River, Raquette River, St. Regis River, and Salmon River). This part of the St. Lawrence River is non-tidal fresh water. Sample locations were randomly selected from a grid of spatial cells (1 km x 1 km) encompassing the area within the 5,700 ha Akwesasne Wetland Complex (at the intersection...

Climate change is expected to alter stream temperature and flow regimes over the coming decades, and in turn influence distributions of aquatic species in those freshwater ecosystems. To better anticipate these changes, there is a need to compile both short- and long-term stream temperature data for managers to gain an understanding of baseline conditions, historic trends, and future projections. Unfortunately, many agencies lack sufficient resources to compile, conduct quality assurance and control, and make accessible stream temperature data collected through routine monitoring. Yet, pooled data from many sources, even if temporally and spatially inconsistent, can have great value both in the realm of stream temperature...

Bee-Gap: Ecology, Life-History, and Distribution of Bee Species in the United States 2017

Bee-Gap describes the ecology, life-history, and distribution of 3,925 bee species in the United States that have geographical data and verified taxonomy. The database was constructed by compiling information from a broad range of internet sources and peer-reviewed journal articles. The 10 traits included in the database are: native status (native versus exotic/introduced), state and territory presence/absence, adult habitat, nesting strategy, voltinism, sociality, host bee species (for parasitic bees only), foraging strategy (generalist vs specialist), known host plants, and tongue length.
