During March and April of 2018, viable seeds were collected from Cañón de Fernández State Park in Lerdo, Durango and sent to Lafayette, LA for germination. This study tested the seedling growth and germination of Taxodium mucronatum from the Nazas River watershed at different salinity concentrations representing freshwater, moderate salinity, and high salinity.

Mitochondrial DNA markers have elucidated patterns of connectivity between green turtle nesting populations (rookeries) and juveniles foraging in neritic nursery habitats. However, missing rookery baseline data and haplotype sharing among populations have often impeded inferences, including ascertaining origins of Gulf of Mexico juveniles. We sequenced the mitochondrial control region and additional informative mitogenomic single nucleotide polymorphisms of juveniles foraging in Port Fourchon, Louisiana (LA, n = 127) and Santa Rosa Island, Florida (SRI, n = 47). We collected additional genetic data for previously characterized neritic aggregations in southern Texas (TX, n = 167), St. Joseph Bay, Florida (SJB, n...
This dataset includes a modified subset of polygon features that describe U.S. Geological Survey's defined geologic provinces of the World. Each province has a set of geologic characteristics that distinguish it from surrounding provinces. These characteristics may include dominant lithologies, the age of the strata, and/or structural type. Each province is assigned a unique numeric code and may fall within two or more countries or assessment regions.

This shapefile represents the offshore grid-based sampling frame intended for use with the North American Bat Monitoring Program (NABat). The grid consists of 10 km x 10 km cells spanning the oceanic waters surrounding Mexico.
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)....

A study using multiple techniques provided insight into tectonic influences on ground water systems; the results can help to understand ground water systems in the tectonically active western United States and other parts of the world. Ground water in the San Bernardino Valley (Arizona, United States and Sonora, Mexico) is the main source of water for domestic use, cattle ranching (the primary industry), and the preservation of threatened and endangered species. To improve the understanding of ground water occurrence, movement, and sustainability, an investigation was conducted using a number of complementary methods, including major ion geochemistry, isotope hydrology, analysis of gases dissolved in ground water,...

These data were compiled for a comprehensive review of pinyon-juniper communities including Pinus edulis, Pinus monophylla, Juniperus osteosperma, Juniperus monosperma, and Juniperus scopulorum. Compiled are a list of references cataloged by the topic of interest resulting from the literature search. The characterization for each reference includes the focal species, descriptions of the site(s) the study was conducted at, type of study, any land management treatments and the measured response variables. The location data for publications that provided location information have also been compiled in order to compare the geographic distribution of these studies with the distribution of the focal tree species.
The Minute 319/323 ScienceBase community exists to share data regarding the 2014 pulse flow experiment in the Colorado River delta. Some content, such as provisional data, is not publicly available. Please contact Jeff Kennedy (jkennedy@usgs.gov) for access.

The diverse, fragile ecosystems of the borderlands have been pushed beyond sustainable levels due to rapid population growth and land use changes. Water shortages and pollution, poor air quality, increased soil salinities, residual pesticides, and heavy metal contaminants are some of the stressors that are degrading the quality of life in the borderlands. The relationship between human health and environmental quality challenges public officials, medical professionals and resource managers on both sides of the border in their efforts to maintain healthy communities. To help understand the relationship between environmental and human health, the U.S. Geological Survey’s U.S.-Mexico Border Environmental Health Initiative...
Consumptive use (CU) of water is an important factor for determining water availability and groundwater storage. Many regional stakeholders and water-supply managers in the Upper Rio Grande Basin have indicated CU is of primary concern in their water-management strategies, yet CU data is sparse for this area. This polygon feature class, which represents irrigated acres for 2015, is a geospatial component of the U.S. Geological Survey National Water Census Upper Rio Grande Basin (URGB) focus area study's effort to improve quantification of CU in parts of New Mexico, west Texas, and northern Chihuahua. These digital data accompany Ivahnenko, T.I., Flickinger, A.K., Galanter, A.E., Douglas-Mankin, K.R., Pedraza, D.E.,...

The USGS Upper Midwest Environmental Sciences Center developed a Monarch Relevant Land Cover data set covering the area of Mexico. We used the 2010 land cover data set produced by the tri-national North American Land Change Monitoring System (NALCMS) and supported by the Commission for Environmental Cooperation (CEC) that depicts year 2010 land cover across North America at 30-meter spatial resolution, and incorporated additional spatially-explicit information to develop this land cover map. Additional sources of information included 2004 railroad data provided by Instituto Nacional de Estadística y Geografía and the CEC, 2011 roads data provided by Instituto Nacional de Estadística y Geografía, 2017 protected areas...

This data set shows areas where the land cover classification changed between 2005and 2010. The 2005-2010 Land Cover Change of North America at 250 meters wasproduced as part of the North American Land Change Monitoring System (NALCMS), atrilateral effort between the Canada Centre for Remote Sensing, the United StatesGeological Survey, and three Mexican organizations including the National Instituteof Statistics and Geography (Instituto Nacional de Estadistica y Geografia),National Commission for the Knowledge and Use of the Biodiversity (ComisiónNacional Para el Conocimiento y Uso de la Biodiversidad), and the National ForestryCommission of Mexico (Comisión Nacional Forestal).

The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water...
