Hawaii Island, Hawaiian hoary bat acoustic data pre- and post-koa moth outbreak, 2007-2013 Hawaii Island, Hawaiian hoary bat acoustic data pre- and post-koa moth outbreak, 2007-2013
We examined Hawaiian hoary bat (Lasiurus semotus) presence and foraging activity at Hakalau Forest National Wildlife Refuge and Lupahoehoe Forest Reserve on Hawai'i Island during the 2013 koa moth (Geometridea: Scotorythra paludicola) outbreak. Hawaiian hoary bat echolocation vocalizations were recorded at seven acoustic stations between 1069 and 1200 m above sea level that operated...
Northern Yellowstone Mule Deer Movements and Demographics Northern Yellowstone Mule Deer Movements and Demographics
This data product includes two datasets acquired for the study of northern Yellowstone mule deer seasonal movement and survival patterns. One data set "Point Locations of Radio-collared female northern Yellowstone mule deer" provides details about the date and time of relocations of radio-collared female northern Yellowstone mule deer along with location coordinates. Habitat types with...
Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River Fluvial Egg Drift Simulator (FluEgg) Results for 240 Simulations of Bighead Carp Egg and Larval Drift in the Illinois River
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). This data release contains results from 240 FluEgg 4.1.0 simulations of bighead carp eggs in the Illinois River under steady flow conditions...
Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020) Developmental Stages of Grass Carp (Ctenopharyngodon idella) eggs in the Sandusky River (ver. 3.0, July 2020)
Grass Carp Ctenopharyngodon idella was imported to the United States in the 1960s for research into its usefulness as a biocontrol agent for nuisance aquatic vegetation. Escapees and intentionally stocked individuals founded wild, spawning populations in the Mississippi River and tributaries to the Laurentian Great Lakes. USGS-led research on the Sandusky River, a tributary to Lake Erie
Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016 Modeled and observed trends at reference basins in the conterminous U.S. from October 1, 1983 through September 30, 2016
This data release contains trend results computed on the basis of modeled and observed daily streamflows at 502 reference gages across the conterminous U.S. from October 1, 1983 through September 30, 2016. Modeled daily streamflows were computed using the deterministic Precipitation Runoff Modeling System (PRMS), and five statistical techniques: Nearest-Neighbor Drainage Area Ratio...
Ecosystem water balance and ecological drought patterns under historical and future climate conditions for the Four Forest Restoration Initiative (4FRI) Landscape Ecosystem water balance and ecological drought patterns under historical and future climate conditions for the Four Forest Restoration Initiative (4FRI) Landscape
These data were compiled for research pertaining to the effects of stand density treatments on growth rates in semi-arid, ponderosa pine forests. Also, these data examined how the planned restoration treatments in the Four Forests Restoration Initiative (4FRI), the largest forest restoration project being implemented in the United States, would alter landscape-scale patterns of forest...
