Humpback chub spring and fall capture histories in the Little Colorado River, 2009-2019 Humpback chub spring and fall capture histories in the Little Colorado River, 2009-2019

These data were compiled to examine rates of skipped migration in adult humpback chub that spawn in the Little Colorado River (LCR). These data include mark-recapture information from the lower 13.56 kilometers of the LCR and from the Colorado River, from river kilometer 105.5-145.7 downstream of Glen Canyon Dam. Data also include detections from a multiplexer array (MUX) that is located...

San Gorgonio Pass Wind Resource Area Repower Data (2018-2019) San Gorgonio Pass Wind Resource Area Repower Data (2018-2019)

Variation in avian and bat mortality as a function of turbine size was investigated in the San Gorgonio Pass Wind Resource Area near Palm Springs, CA. Five sites were monitored for carcasses by dog-handler teams every 3 days from May 2018 to April 2019. The data consist of six tables used for analyses on mortality rates including: specifications on selected wind turbines (including...

Astragalus species complex genetic data from southeast Utah (Grand County and San Juan County), USA Astragalus species complex genetic data from southeast Utah (Grand County and San Juan County), USA

These data were compiled to investigate the evolutionary history of Astragalus iselyi, A. sabulosus var. sabulosus, and A. sabulosus var. vehiculus. The data release consists of six text files. One file is a bash script (astragalus_MLE_msms.sh) for generating simulated genetic data. Four files contain individual-level (astragalus.fasta, astragalus.nothin.recode.vcf, astragalus.recode.vcf...
