Species occurrence records of the taxonomic class of Bivalvia in oceans within 1000 kilometers of the United States shoreline. This is a subset of the OBIS-USA dataset where Bivalvia records were queried on December 2, 2014. After initial queries, the remaining data were further queried to retain only samples within 1000 kilometers of the U.S. shoreline. Spatial queries were then used to remove samples overlaying land masses. Data are provided in a geodatabase format, as well as a comma seperated values format. OBIS-USA provides aggregated, interoperable biogeographic data collected primarily from U.S. waters and oceanic regions--the Arctic, the Atlantic and Pacific oceans, the Caribbean Sea, Gulf of Mexico and...

Habitat Condition for Imperiled Species is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This product represents a regional network of habitats critical for sustaining populations of imperiled species, currently based on over 600 Species of Greatest Conservation Need (SGCN). A number of additional datasets that augment or complement Habitat Condition for Imperiled Species, including Core Habitat for Imperiled Species, are also available in the Nature’s Network gallery. A detailed technical...

This service definition contains landscape factors representing human disturbances summarized to local and network catchments of river reaches for the state of Arizona. This dataset is the result of clipping the feature class 'NFHAP 2010 HCI Scores and Human Disturbance Data for the Conterminous United States linked to NHDPLUSV1.gdb' to the state boundary of Arizona. Landscape factors include land uses, population density, roads, dams, mines, and point-source pollution sites. The source datasets that were compiled and attributed to catchments were identified as being: (1) meaningful for assessing fish habitat; (2) consistent across the entire study area in the way that they were assembled; (3) representative of...

Core Habitat for Imperiled Species is one of a suite of products from the Nature’s Network project (naturesnetwork.org). Nature’s Network is a collaborative effort to identify shared priorities for conservation in the Northeast, considering the value of fish and wildlife species and the natural areas they inhabit. This product represents a regional network of the most intact of habitats estimated to be most important for sustaining populations of imperiled species, currently based on over 600 Species of Greatest Conservation Need (SGCN).A number of additional datasets that augment or complement Core Habitat for Imperiled Species, including Habitat Condition for Imperiled Species (the more extensive dataset from...
