Software for the program code AFCE (Aqueous-Flow-Concentration-Estimator) for estimation of ambient groundwater flow in bedrock open boreholes using concentrations of chlorinated volatile organic compounds from coupled straddle packer and passive sampling Software for the program code AFCE (Aqueous-Flow-Concentration-Estimator) for estimation of ambient groundwater flow in bedrock open boreholes using concentrations of chlorinated volatile organic compounds from coupled straddle packer and passive sampling
Software program code for the AFCE (Aqueous Flow Concentration Estimator) that is used to estimate inflow of groundwater contaminants to a water column of an open borehole in a fractured-rock aquifer. It is particularly useful program for assessing ambient flow in low permeability open boreholes, which have no detectable flow as measured with conventional borehole flowmeter tools. The...

Geochemical data for water, sediment, and biota in Lake Combie, California, 2017-2021 Geochemical data for water, sediment, and biota in Lake Combie, California, 2017-2021
This dataset includes field measurements and laboratory analyses of surface water, bottom water (sediment-water interface), surficial (0-2 cm) sediment, pore water (0-2 cm), and biota collected in Lake Combie, California, from September 2017 through August 2021. The study area includes six sites within the reservoir where discrete samples of surface water, bottom water, sediment, and...
Capsaicin-treated bait trials for Argentine Black and White Tegu lizards in Georgia and Florida, USA 2020-2021 Capsaicin-treated bait trials for Argentine Black and White Tegu lizards in Georgia and Florida, USA 2020-2021
Invasive Argentine Black and White Tegu lizards (Salvator merianae) are trapped with chicken eggs when populations are discovered in the United States. Unfortunately, non-targeted mammals are trapped in tegu lizard traps which reduces trap efficacy. We evaluated if non-target mammal captures could be reduced by coating the chicken eggs with a known irritant to mammals (capsaicin) while...
Oregon spotted frog (Rana pretiosa) captures before and after drought mitigation at Jack Creek, Oregon 2009-2021 Oregon spotted frog (Rana pretiosa) captures before and after drought mitigation at Jack Creek, Oregon 2009-2021
Amphibians are among the most sensitive taxa to climate change, and species inhabiting arid and semiarid landscapes at the extremes of their range are especially vulnerable to periods of drought. The Jack Creek, Oregon, USA population of Oregon spotted frogs (Rana pretiosa) faces unique challenges occupying the highest elevation site in the species’ extant range and one that has been
