The Sonoran Joint Venture Bird Conservation Plan (Plan) provides the biological foundation for the activities of the Sonoran Joint Venture (SJV). The Plan summarizes the status of avian species, prioritizes these species, provides habitat discussions and conservation recommendations, and lists Focus Areas for conservation action. This Plan will be a blueprint for regional bird conservation. It will guide the SJV staff, Board, and committees in their actions and inform SJV partners of beneficial activities. Finally and most importantly, this Plan demonstrates and emphasizes the need for conservation action and for the resources to achieve the SJV’s biological objectives. There are approximately 740 species documented...

This dataset presents information about facilities relating to the mineral industries of Latin America and the Caribbean. Facilities include mines, mineral processing plants (including refineries and smelters), oil and gas field locations, and petroleum refineries. Relevant data fields include the mineral commodity, specific forms of the mineral commodity produced, location information, facility name, operator, ownership of the facility, annual production capacity, operational status, as well as geographic coordinates and locational accuracy. These data are derived from data presented by country by the Global Minerals Analysis section of the U.S. Geological Survey's (USGS) National Minerals Information Center (NMIC)...
This sampling frame is a set of grid-based finite-area frames spanning Canada, the United States, and Mexico. The grid for the United States is broken into individual grids for the continental United States, Hawaii, and Puerto Rico. Alaska is combined with Canada into a single grid. Each country/state/territory extent consists of four nested sampling grids at 50x50km, 10x10km, 5x5km, and 1x1km resolutions. The original 10x10km continental United States grid was developed by the Forest Service, U.S. Department of Agriculture for use in the interagency “Bat Grid” monitoring program in the Pacific Northwest and was expanded across Canada, the United States, and Mexico for the North American Bat Monitoring Program (NABat)....

Subterranean estuaries extend inland into density-stratified coastal carbonate aquifers that contain a surprising diversity of endemic animals (mostly crustaceans) within a highly oligotrophic environment. How complex ecosystems thrive in this globally-distributed, cryptic habitat (termed anchialine) is poorly understood. The northeastern margin of the Yucatan Peninsula contains over 250 km of mapped, diver-accessible caves passages where previous studies have suggested chemoautotrophic processes are the source of carbon and energy sustaining the anchialine food web. This dataset, collected during four field events during U.S. Geological Survey (USGS) Coastal and Marine Geology Program Field Activities 2015-013-FA...

The NABat sampling frame is a grid-based finite-area frame spanning Canada, the United States, and Mexico consisting of N total number of 10- by 10-km (100-km2) grid cell sample units. This grain size is biologically appropriate given the scale of movement of most bat species, which routinely travel many kilometers each night between roosts and foraging areas and along foraging routes. A draw of sample units from a finite sampling frame using the GRTS design produces an ordered list of units such that any ordered subset of that list is also randomized and spatially balanced. This vector dataset is the individual grid-based sampling grid for Mexico at a 10x10km resolution.
