We conducted a study to test the factors related to detectability of two invasive aquatic plants (Egeria densa and Myriophyllym spicatum) using environmental DNA (eDNA), over extended periods of time, and specifically examined how plant growth stage and abundance relates to eDNA detection in semi-natural and natural conditions. This dataset is from sampling performed in summer of 2018 in...

Algal toxins are a growing concern worldwide. Rapid assessment test strips are a newer technology and their accuracy in detecting toxins in different lakes with different phytoplankton and toxins present is unknown. This data release is supported by our testing of toxin test strips. This research took place in Voyageurs National Park in northern Minnesota. The research will indicate...

The Colorado Plateau is associated with several different commercial sources of natural CO2 and other non-hydrocarbon gases, such as noble gases. Twenty-five different hot springs, warm springs, cold springs, and/or rivers across the Utah region of the Colorado Plateau were sampled for microbial biomass. These different locations were associated with some concentration of dissolved or

Low biomass waters provide a unique challenge in the field of microbial ecology. It is difficult to determine, when biomass concentrations are extremely low, whether or not the sequencing data received are of good quality and representative of the waters sampled. Fifty-nine samples including 8 blanks were collected from a low biomass hydraulically fractured well producing from the...

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center in St. Petersburg, Florida (USGS-SPCSMC), conducted a bathymetric survey of the Northern Chandeleur Islands, in August 2018. During this study, multibeam bathymetry data were collected aboard the research vessel (R/V) Sallenger, while single-beam bathymetry data were collected aboard the R/V Jabba...

Data release consists of five comma delimited text files containing discharge and sediment data for five gaged tributaries to the Anacostia River in Washington, District of Columbia. Data were collected from 2003 through 2018.

The data associated with the following data release were collected between 2016 and 2017 at three locations on Lake Michigan: Racine, WI; Chicago, IL; and East Chicago, IN. Individual water samples were collected one day a week for ten weeks between June and August. Samples were collected from eight specific sites made up of two river and six shoreline type environments. Sampling was...

This dataset describes incubation recess timing for mallard and gadwall hens nesting in Grizzly Island Wildlife Area in breeding seasons 2015-2017. It includes the start time, end time, and duration of recesses. This data supports the following publication: Croston, R., Hartman, C.A., Herzog, M.P., Casazza, M.L., Feldheim, C.L. and Ackerman, J.T., 2020. Timing, frequency, and duration of

These data show the multilocus genotypes, gender, and midline carapace length (MCL) for desert tortoises (Gopherus agassizii) sampled in the central portion of the Mojave desert tortoise range. This data supports the following publication: Dutcher, K.E., Vandergast, A.G., Esque, T.C., Mitelberg, A., Matocq, M.D., Heaton, J.S. and Nussear, K.E., Genes in space: what Mojave Desert tortoise

Sediment composition data to support the manuscript "Multivariate analysis of shale gas development on the chemical and biological health of headwater streams".

This dataset is a set of transition probabilities that were elicited from a group of relevant experts during a structured decision-making workshop. Each value is the probability of a wetland in a given state undergoing a transition to another state during a single time step, given a potential management action is taken.

These data quantify components of the carbon cycle within Big Cypress National Preserve in Florida. Continuous data time-series include net ecosystem exchange of carbon dioxide, methanogenesis, and soil bulk density.
