Up to 12 different prey fish species were sampled with a 12-m bottom trawl during April, July, and September along two Lake Huron transects (Thunder Bay, Hammond Bay). At each transect in each month, two replicate 10-min tows were conducted at each of three depths (18, 46, 82 m) during the day and night. Once the fish were onboard in a given tow, they were sorted to species, weighed (in aggregate), and up to 50 individuals per species were measured to the nearest total length.

The Fluvial Egg Drift Simulator (FluEgg) estimates bighead, silver, and grass carp egg and larval drift in rivers using species-specific egg developmental data combined with user-supplied hydraulic inputs (Garcia and others, 2013, Domanski, 2020). Hydraulic inputs for a series of FluEgg simulations were generated using a one-dimensional steady Hydrologic Engineering Center-River Analysis System (HEC-RAS) 5.0.7 model for the Illinois River between Marseilles Lock and Dam and the Mississippi River confluence near Grafton, Illinois (HEC-RAS, 2019). The HEC-RAS model was developed by combining four individual HEC-RAS models obtained from the U.S. Army Corps of Engineers Rock Island District (U.S. Army Corps of Engineers...
Plant cover data were collected in experimental plots at two sites, one at Badlands National Park, South Dakota, and one at Scotts Bluff National Monument, Nebraska. At each site, 40 50 x 50 m plots were assigned randomly to one of the following treatments: control (no action), burn-only (prescribed fire in fall 2016), burn+herbicide (prescribed fire followed by imazapic application in fall 2016), and burn+seed (prescribed fire followed by drilling native grass seed in fall 2016). Pre-treatment data were collected in 2015, and post-treatment data were collected in 2017 and 2018. The dataset includes four tables: (1) plant cover and species richness metrics analyzed in the larger work; (2) plant canopy cover data...

The table illustrates global patterns of betacoronavirus (β-CoV) associations in bats. The table lists bat species in which betacoronaviruses (β-CoVs) were detected, organized by viral subgenera and clade [for Sarbecorviruses], bat family, bat suborder, and general global region where the species of bat occurs. Reference to the published literature sources of information for each row are listed in the last column.
Near-term future invasive species, insects, and disease potential distribution model, summarized to 1KM grid cell reporting units for the San Luis Valley - Taos Plateau Study Area. Attribute IID_N_CAT1 is valued along a scale of low potential future distribution to high potential future distribution. The results are based on Landscape Assessment modeling efforts to characterize the potential future risk of invasion by exotic species and forest insect pests and diseases.

The Visual Resource Inventory Classes data were provided by BLM. This dataset presents current and future change agent models and combined future potential for climate change (PFC) within Visual Resource Inventory Classes. Potential for change (PFC) was determined by calculating the maximum potential for change among all change agents within each 1 km reporting unit. Current and future landscape intactness (LCM_C_FZ and LCM_N_FZ) are based on measures of landscape development and invasive species. Current vegetation departure (VDEP) is based on LANDFIRE vegetation departure and characterizes the departure of current vegetation from historic reference vegetation conditions. Current and future human development (DEV_C_FZ...

We conducted the first investigation of insect community responses to post-fire seeding on public rangelands by comparing the composition of insect communities at burned-and-seeded (treatment) and burned-and-unseeded (control) sagebrush-steppe ecological sites in southwestern Idaho. Insect communities in burned areas were compared to unburned (reference) areas. We collected insect and vegetation data within and around the burn perimeter of the 2007 Murphy Fire (652,209 ha), 2002 Big Crow Fire (1,134 ha), and 1995 Clover Fire (78,102 ha) in southwestern Idaho, USA. We captured and identified 24,862 insects from 130 families at the three study sites in 2010. We used a nadir photogrid and point-centered quarter method...
