Data presented are 1.) the locations where Coastal Cactus Wren (Campylorhynchus brunneicapillus) genetic samples were collected in southern California, in 2011, 2012, and 2013; 2.) 2012 and 2013 survey results; 3.) the territory locations of all Cactus Wrens detected in 2011, 2012, and 2013 in Orange, Riverside, and San Diego counties; and 4.) dispersal results on a subset of Cactus Wrens color banded in 2011.

The Coastal Cactus Wren is a species of high conservation concern in southern California. The goal of this project was to obtain taxonomic resolution of subspecies boundaries between coastal and desert populations of Cactus Wrens. We collected genetic samples from Cactus Wrens at California desert sites and combined this dataset with previously collected samples from coastal populations to resolve the distribution of subspecies and to determine distinct genetic lineages, gene flow, genetic diversity and effective population size of desert populations. Understanding these relationships will assist managers with development and implementation of a conservation and management strategy that could aim to avoid state or federal listing of this declining species.

This dataset contains 184 single nucleotide polymorphism (SNP) genotypes of Campylorhynchus brunneicapillus (Cactus Wren) sampled in southern California. Genomic markers were generated from ddRAD loci and analyzed using the Stacks v2.60 pipeline. The genotypes for all samples are provided in a VCF file with 40,707 independent loci. A companion sample data file is provided with sample names, location, and other data. These files may be opened and edited in a text editor program, such as Notepad (PC) or BBEdit (Mac). The .vcf file can be loaded into the Stacks population program to calculate genetic diversity statistics, or loaded into R, using vcfR, for further analysis.

These data show the multilocus genotypes, gender, and midline carapace length (MCL) for desert tortoises (Gopherus agassizii) sampled in the central portion of the Mojave desert tortoise range.

This dataset contains single nucleotide polymorphism (SNP) information for aquatic insect species collected in tributaries of the Colorado River in Grand Canyon (Arizona, USA), as well as SNP information for individuals collected from reference reaches of the Upper Colorado River Basin in Utah. This dataset focuses specifically on three species that were common and widely distributed throughout tributary streams in Grand Canyon: a mayfly (Fallceon quilleri), a caddisfly (Hydrospyche oslari), and a water strider (Rhagovelia distincta).

Monitoring population connectivity to inform management is especially important in regions at the very edges of wilderness where native fauna and flora face habitat reduction, degradation, and fragmentation. One such region is the Ivanpah valley along the California/Nevada border, where development (i.e., solar facilities, recreational utility vehicle use) continues to encroach on the habitat of its inhabitants, including the iconic Mojave Desert tortoise, Gopherus agassizi. A long-lived, elusive animal, this species poses an array of challenges to monitoring direct movement, including the challenging terrain in which it resides and the fact that individuals can spend as much as 95 percent of their time in burrows. Thus, genetic monitoring of gene flow and population structure can be an ideal complement to direct monitoring of tortoise movement. Our group has previously evaluated the spatial population genetic structure of the tortoise in the Ivanpah region using a dataset of 299 individuals sampled between 2011 and 2019 and genotyped at 20 microsatellite loci (Dutcher et al., 2020). We found support for historical gene flow with isolation-by-resistance and suggested that connectivity may have been reduced by a railway and highway bisecting the region. We continued to follow up on these findings, collecting additional samples and developing a set of 125 high-throughput microsatellite loci designed specifically for G. agassizi. This data release contains multilocus genotypes collected by high-throughput genotyping for 722 tortoises collected in the region and will be used to explore fine-scale population genetic dynamics, reconstruct pedigrees, and infer movement patterns.

Data presented are results of surveys in 2021 for San Diego Cactus Wren (Campylorhynchus brunneicapillus) in southern San Diego County. Surveys were conducted at 378 plots. Plots were surveyed twice in 2021 and the number, age (adult or juvenile), banding status (color banded or not), and breeding status (paired, unpaired, or unknown) of all wrens recorded. Habitat covariate data were collected including amount of dead and stressed cactus in the plot, percent cover of bare ground, and the dominant and percent cover of invasive species.
