Daily Survival Rates of Grassland Passerines and Associated Weather Variables (1978-2013)

This data set contains daily survival rates from 81 studies of passerine obligate grassland bird species that primarily breed in the United States; patch size information was extracted when available. Temperature and precipitation variables were calculated for the study sites and years the data were collected. The studies we used collected data across the period 1978 to 2013.

Microsatellite genotypes for Lake Sturgeon (Acipenser fulvescens) Eggs and Larvae from Constructed Reefs in the St. Clair-Detroit River System (2015-2016)

This dataset contains the physical collection information (e.g., sample location, date, gear type) and microsatellite DNA genotype of egg and larval Lake Sturgeon collected in the St. Clair and Detroit rivers in 2015 and 2016. Individuals were genotyped for 18 microsatellite loci (13 disomic and 5 polysomic). Alleles (base pair sizes) were recorded as presence absence scores (1:present, 2:absent, 0:missing data) for all previously observed alleles. Thus individual genotypes were recorded as pseudo diploid dominant phenotypes resulting in individual vectors of length n=205 for each genotyped egg or larval individual.

Kentucky Karst Groundwater Map Data

This dataset provides the geographical locations of karst groundwater basins, groundwater flowpaths, and dye injection/recovery points in Kentucky. Dye tracing is a common method used for understanding groundwater flow pathways and connectivity. Dye is poured (or injected) into a sinking stream, well, sinkhole, or body of flowing water, where it is carried down-gradient. The locations at which dye is detected (or recovered) indicates a connection from injection to recovery site. This connection is a groundwater flowpath. As more dye traces are conducted, flowpath convergence or lack thereof can be used to draw karst groundwater basins, which are analogous to surficial watersheds. Karst groundwater basins differ...

Samples from Green River oil shale cores

This collection consists of core plugs and pulverized samples taken from three Green River oil shale cores. The cores are: Blacks Fork, Coyote Wash and Barcus Creek cores. These cores were each drilled in the depositional center of the three major Green River basins in Wyoming, Colorado, and Utah to support research into oil shale resources. The cores themselves are part of the UGSG Core Research Center Collection of Core. Samples were taken in the 1980s to support research focused on the geochemistry of the Green River oil shale by Michele Tuttle. The samples are maintained as a collection to support future research for Colorado, Wyoming, and Utah oil shale projects, specifically for the development of infrared...

Fledging times of grassland birds in North Dakota and Minnesota

The data set provides information on the fledging times of passerine grassland birds. Data were collected from video surveillance of 70 nests of 9 bird species that nested in grasslands of Minnesota and North Dakota, USA. The data include year, unique nest number, species, date and time of fledging by nestling.
