These data represent a case study on managing the invasive brown treesnake (Boiga irregularis) on Guam within a 5 ha snake enclosure located on Northern Guam. The site code (NWFN or North West Field North) reflects a location on Andersen Air Force Base, Northern Guam, which has been a study site for close to two decades. The experimental process followed an adaptive resource management process to develop an integrated pest management strategy for either eradication or validating whether extant species (rodents, lizards, and birds) would respond to population suppression over a 6 year removal effort. The program included an evaluation of the Aerial Delivery System, as well as a comparison of bait species (quail,...

We tested salinity tolerance of grass carp and silver carp eggs and larvae during two phases of development – pre-gas bladder inflation and post gas bladder inflation to the development of the second gas bladder chamber, using 6 different salinity concentrations ranging from 0 to 36 ppt. Growth and developmental rates were also observed after exposure. After the initiation of horizontal swimming, grass carp larvae were tested in a Y-maze to assess any preferences for salinity levels.
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to arresting coastal wetlands loss. This data set includes mosaicked aerial photographs for the East Marsh Island Marsh Creation (TV-21) project for 2021. This data is used as a basemap land-water classification. It also serves as a visual tool for project managers to help them identify any obvious problems or land loss within their...

These data contain ambrosia beetle (Coleoptera: Curculionidae) trapping data using two different repellents in two different trials at Waiākea Forest Reserve. Beetles were trapped using cross vane panel traps equipped with 50:50 Ethanol:Methanol lures in the first trial and with black panel multi-traps equipped with 100% Ethanol lures in the second trial. Both trials tested the ability of two different beetle repellents, one verbenone formulation, and one verbnone + methyl salicylate, to deter beetle catch.
This data release includes individual lengths, total dry mass, and taxonomic classification for a subset of adult aquatic insects captured emerging from the surface of wadeable wetlands in cropland and grassland landscapes across a salinity/hydrology gradient (N = 14 wetlands in 2015, N = 15 wetlands in 2016). Sampling was completed in late spring, after ice off was complete and during the local bird breeding season. Wetlands were situated on 3 USFWS Waterfowl Protection Areas and 2 private farms in Stutsman County, North Dakota, USA. Other portions of this data such as sampling locations and pesticide concentrations are reported in Kraus et al. 2021 (https://doi.org/10.5066/P971S7IV)

These data were compiled to provide a quantitative, spatially explicit estimate of ecological resilience and resistance (R&R) under ambient and projected future climate conditions. Objective of our study was to understand where and why climate change will alter the distribution of ecological resilience and resistance in the sagebrush biome throughout the 21st century. To accomplish this, we pursued four specific objectives: we estimated the new R&R indicators under future climate conditions and quantified changes from historical conditions; we developed a continuous R&R index that integrates probability information from the underlying predictive R&R models; we assessed the robustness of projected changes in R&R...
This data set is comprised of one table with sampling information and National Center for Biotechnology Information (NCBI) BioProject accession numbers for sequence information of this amplicon-based study targeting Elodea canadensis and E. nuttallii in freshwater systems of Alaska from environmental samples. Highly conserved primers which can differentiate these species of interest were developed for four portions of Elodea mtDNA genes (ITS1-5.8S, atpB-rbcL, and two variations of trnL-trnF). The reference sequences and conserved primer sets to identify species present were developed using publicly available data from NCBI GenBank (https://www.ncbi.nlm.nih.gov/genbank/).
This data was used for the analysis in the paper "Assessing factors related to Walleye stocking success in the midwestern United States". This data includes stocking records of walleye from the Midwestern United States and subsequent evaluations of these stockings as provided by state agencies. Additionally, attributes of lakes such as size (depth, area), trophic state, and temperature are included to evaluate factors that relate to walleye stocking success.
