Mayflies (Ephemeroptera), stoneflies (Plecoptera), and caddisflies (Trichoptera) (a.k.a. EPT taxa) are the most environmentally sensitive of freshwater insects. They are utilized the world over as indicators of water quality in flowing waters. Their decline has been documented in Asia, Europe, and North America. A 220,321 record dataset of new and museum EPT specimen records covering much of the Midwest and Maximum Entropy (Maxent) software were used construct to current and future, climate influenced distribution models. Nearly 100 physical and historic vegetation variables and 9 BIOCLIM variables derived from downscaled climate data for the region were employed in this process. A total of 426 EPT species were...

These data were compiled to improve our understanding of bat foraging along the Colorado River in Grand Canyon. Objectives of our study were to determine whether bat activity was influenced primarily by variation in prey availability relative to other environmental or geomorphic factors. These data represent 1,428 paired samples of bat activity and insect abundance calculated as catch rates collected on 611 sampling nights at 410 sampling sites throughout a 470 km segment of river. These data were collected from April to October in 2017-2020 at recreational camps along the Colorado River in Grand Canyon between Glen Canyon Dam and Pearce Ferry. These data were collected through a U.S. Geological Survey led community...
