Data

Data were collected on the seed production and genetic diversity of Lepidium draba, an invasive plant. Site characteristics were also measured for 26 sites throughout northern Colorado. In addition, a pollen supplementation experiment was conducted at six of those sites, in which L. draba plants were pollinated with within-population pollen, among-population pollen, or were not...

Polar bears (Ursus maritimus) are difficult to study because of logistical challenges. Satellite radio collars are an excellent tool for efficiently collecting information on the distribution and habitat use of polar bears because they can be deployed for multiple years. Radio collars can be constructed using materials and devices that result in the collar falling off an animal so that...

We evaluated potential effects of deltamethrin and fipronil on tiger salamander (Ambystoma mavortium) body mass, behavioral activity, and insecticide tissue residues. Insecticides were applied at realistic concentrations in mesocosms mimicking prairie dog burrows, which are used as refuge by salamanders under natural conditions. Treatments included (1) deltamethrin dust, (2) prairie dog...

These data support the following publication: "Assessing causes and consequences of winter surface water dynamics in California’s Central Valley using satellite remote sensing". The file contains information associated with surface water inundation, antecedent soil moisture, and atmospheric river storm characteristics for 2003-2023 in the three HUC-4 hydrologic sub-basins that make up...

We simulated a 3-hour, 1-km spatially seamless surface soil moisture (SSM) dataset (called STF_SSM) in the Contiguous United States (CONUS) using a virtual image pair-based spatio-temporal fusion method. This proposed approach effectively fuses the distinct advantages of two long-term SSM datasets, namely, the Soil Moisture Active Passive (SMAP) L4 SSM product and the Crop Condition and...

Invasive carp pose substantial economic and ecological damage when populations are widespread in freshwater systems within the United States of America (USA). Resource managers in the USA have a limited number of chemical control tools to selectively remove nuisance fish. The present study examined whether Antimycin-A (antimycin) wax encapsulated microparticles could cause selective...

Multiple generations of spring-fed streams traversed ~800 km2 of the Las Vegas Valley in southern Nevada between ~10.9 and 8.5 ka, depositing an extensive tufa network. The scale of this network and diversity of tufa morphologies is novel in North America and offers an opportunity to obtain quantitative paleoclimate data for the region during the early Holocene. We determined isotopic...

Northern deltas receive chromophoric dissolved organic matter (CDOM) from their watersheds, which can be oxidized to carbon dioxide upon absorption of sunlight (i.e., photomineralized). These deltas also receive total suspended solids (TSS), which may shade sunlight absorption by CDOM, thus limiting photomineralization. To quantify this interaction for the first time, we measured

Variability in river discharge, particularly very high flow and low flow conditions, has far-reaching environmental and economic consequences. The retention of water in surface storage, concentrated in lakes, ponds, wetlands, floodplains, and temporary water in flood prone areas, can potentially contribute to flow generation and flood regulation. However, the impact of surface water...

This report details the luminescence ages and characteristics of four (4) samples that were collected by Jessica Jobe and Rich Briggs of the USGS. These samples are from Holocene and Pleistocene sediments offset by a fault that is exposed in a road cut. The roadcut is in Puerto Rico at 18.003828 and -67.140249 with an elevation of 13.5 m. The sample depths from the modern surface varied...

The impacts of white-nose syndrome (WNS) on many bat species in eastern North America have been well-documented due to the length of time that the causative agent, Pseudogymnoascus destructans (Pd), has been present and the ability to monitor bat hibernacula in that region. However, the disease outcomes for bat species in western North America are less known because of the more recent...

Sea-level fluctuations due to the growth and decay of continental ice sheets of the Quaternary exert a strong influence on geologic processes along coastlines. The California Channel Islands are no exception to this, and many studies have been conducted that focus on the extremes of these glacial-interglacial cycles, such as the last glacial period (marine isotope stage [MIS] 2) and the...
