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.

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.

Strontium isotope sourcing has become a common and useful method for assigning sources to archaeological artifacts. In Chaco Canyon, an Ancestral Pueblo regional center in New Mexico, previous studies using these methods have suggested that significant portion of maize and wood originate in the Chuska Mountains region, 75 km to the East. In the present manuscript, these results were tested using both frequentist methods (to determine if geochemical sources can truly be differentiated) and Bayesian methods (to address uncertainty in geochemical source attribution). It was found that Chaco Canyon and the Chuska Mountain region are not easily distinguishable based on radiogenic strontium isotope values. The strontium...

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.
