Microsatellite Genetic Data for Sea Sandwort (Honckenya peploides) and Merckia (Wilhelmsia physodes), Alaska 2009-2016

This dataset contains sampling information and genetic data of 12 novel microsatellite loci developed and polymorphic in the Sea Sandwort (Honckenya peploides) and screened in Merckia (Wilhelmsia physodes) from Alaska. The allele sizes for the 12 microsatellite loci developed in this study are included for two populations of Sea Sandwort (Fossil Beach, Kodiak and Egg Bay, Atka) and one population

Predicted carnivore conservation hotspots in Peninsular Malaysia

A raster surface identifying hotspots of conservation priority based on 375 location records (89 unique geographic locations) of 28 species of Carnivora in Peninsular Malaysia. Hotspot analysis was conducted by calculating the Getis-Ord Gi* (pronounced G-i-star) statistic, using IUCN Red List status rank for each species as a weighting variable. Raster cell values represent a kernel density of z-s

Antibiotic-Resistant Escherichia coli in Migratory Birds Inhabiting Remote Alaska, 2015

This data set includes information on collections of fecal or cloacal samples from wild birds at two locations in Alaska, USA. Samples were screened or Escherichia coli (E. coli) and tested for resistance to multiple antibiotics using a variety of methods.

Data Release for Analysis of Vegetation Recovery Surrounding a Restored Wetland using the Normalized Difference Infrared Index (NDII) and Normalized Difference Vegetation Index (NDVI)

This dataset contains data used in the associated publication in the International Journal of Remote Sensing. The geodatabase contains four feature classes: AOI, MajorZone, MinorZone, and Green2007. Publication can be found at https://doi.org/10.1080/01431161.2018.1437297. Publication abstract: Watershed restoration efforts seek to rejuvenate vegetation, biological diversity, and land productivit

Single-Beam Bathymetry Data Collected in 2015 from Grand Bay, Mississippi/Alabama

This data release archives processed single-beam bathymetry (SBB) data, collected from May 28-June 3, 2015 (USGS Field Activity Number 2015-315-FA) within Grand Bay Mississippi/Alabama, as part of the Sea level and Storm Impacts on Estuarine Environments and Shorelines project (SSIEES). The goal of the SSIEES project is to assess the physical controls of sediment and material exchange between wetl

Corallimorph Invasion Palmyra: Data

In 2007, a phase shift from corals to corallimorpharians (CM) was documented at Palmyra Atoll, Line Islands, centered around a shipwreck. Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency of the atoll, to r

USGS Klamath River Basin Water-Quality Mapper

This map interface represents continuous and discrete water-quality data collected by Bureau of Reclamation and USGS at Klamath Basin sites. The USGS and Reclamation data stored in NWIS are accessible using existing tools such as NWIS-Web and the USGS Data Grapher system.

Data for Montane-breeding Bird Distribution and Abundance across National Parks of Southwestern Alaska, 2004-2008

Observation data and model covariate data from breeding bird inventory conducted during May-June 2004 and 2008 primarily in montane areas (>100 m above sea level) in Aniakchak National Monument and Preserve (Aniakchak NMP), Katmai National Park and Preserve (Katmai NPP), and Lake Clark National Park and Preserve (Lake Clark NPP) in southwestern Alaska. Observers conducted 1,021 point counts along

Landsat classification of surface water for multiple seasons to monitor inundation of playa wetlands

To improve understanding of the distribution of important, ephemeral wetland habitats across the Great Plains, we documented the occurrence and distribution of surface water in playa wetland complexes for four different years across the Great Plains Landscape Conservation Cooperative (GPLCC) region. Years of research on playas has yielded multiple mechanisms and projections for sub-regions of the

Elevation of salt marsh units in Edwin B. Forsythe National Wildlife Refuge, New Jersey

Elevation distribution in the Edwin B. Forsythe National Wildlife Refuge (EBFNWR), which spans over Great Bay, Little Egg Harbor, and Barnegat Bay in New Jersey, USA is given in terms of mean elevation of conceptual marsh units defined by Defne and Ganju (2016). The elevation data is based on the 1-meter resampled 1/9 arc-second resolution USGS National Elevation Data. As part of the Hurricane San

Continuous Bathymetry and Elevation Models of the Massachusetts Coastal Zone and Continental Shelf

Integrated terrain models covering 16,357 square kilometers of the Massachusetts coastal zone and offshore waters were built to provide a continuous elevation and bathymetry terrain model for ocean planning purposes. The area is divided into the following four geographical areas to reduce file size and facilitate publishing: Massachusetts Bay from the Massachusetts-New Hampshire border south to Pr

Exotic invasive giant apple snails (Pomacea maculata) will depredate eggs of frog and toad species of the Southeastern United States

Frog eggs of three different species were presented to giant apple snails (Pomacea maculata) to determine if the snails will eat the eggs. There were four treatments: control-eggs in water only; control with lettuce-eggs in water and lettuce which was used as snail food; snail-eggs in water with snail; and snail with lettuce-eggs in water with snails and lettuce (as an alternative food for the sna
