The dataset includes 492 digitized prints of large-format photographs from 160 viewpoints. A separate metadata file "Photographs Showing Change in Riparian Vegetation in the Grand Canyon, 1889-2012" describes a comma-delimited file of descriptive information. The viewpoints were first photographed by Stanton in 1889, and then re-photographed in about 1991, 2010 and sometimes other years. This set of photos focuses on change in riparian vegetation and partially overlaps a larger set of Stanton viewpoints re-photographed by Webb and others and available at http://wwwpaztcn.wr.usgs.gov/fscc/stanton-repeat-photography/index.php. The file of descriptive information gives viewpoint stake number, name, and river mile,...
A survey of public honey bee sequence data was performed to detect infections by Lake Sinai Virus (LSV). The Sequence Read Archive of the National Center for Biotechnology Information (NCBI) was queried to identify accessions of RNA sequence data derived from honey bee. These were filtered as described below and then up to 50 million reads or read pairs were downloaded and searched against a reference database of conserved LSV sequence. Accessions with matches above a specified threshold were downloaded in their entirety and assembled into longer contiguous sequences (contigs). The result contigs were searched against each open reading frame (ORF) of the reference LSV genome present in the NCBI database (accession...

Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska–Siberia (WA–S), Northern Canada–Nunavut (NC–N), West-central Canada–Interior Alaska (WC–A) and East-central Canada–Minnesota (EC–M). WA–S and NC–N cranes primarily are composed of the lesser sandhill crane (A. c. canadensis) subspecies that breeds in the arctic, whereas WC–A and EC–M cranes are composed primarily of greater sandhill cranes (A. c. tabida), birds which breeds in northern parts of temperate...

This data set is part of a data release as a companion to a manuscript titled "Foraging movements and colony attendance of least terns (Sternula antillarum) on the central Platte River". This data release includes three tabular digital data file representing movement patterns, behaviors, and foraging success of least terns that nested on sandpits near the Platte River during 2009 and 2010. Movement, behavior, and foraging data were collected at the sandpits where birds nested as well as on riverine sites.
This dataset contains the specific conductance values of water for all wetlands in the Cottonwood Lake Study Area, Stutsman County, North Dakota.

These data represent the measurements of length and mouth gape from large juvenile and adult wild-caught and small juvenile hatchery origin black carp, and the results of laboratory size preference trials with bivalve prey, specifically Corbicula clams. Wild-caught black carp ranged from 429-1580 mm total length, a larger range than measured in previous studies. Corbicula feeding trial data consist of the shell dimensions of each clam, survival, and the frequency which clams were engulfed by black carp.
