Salt marshes of the Northeastern United States (Maine to Virginia) are vulnerable to loss given their history of intensive human alteration. One direct human modification – ditching – was common across the Northeast for salt hay farming since European Colonization and for mosquito control in the first half of the 20th century. We hand-digitized linear ditches across Northeastern intertidal emergent wetlands from contemporary aerial imagery within the bounds of the National Wetland Inventory's Estuarine Intertidal Emergent Wetland areas.

Projections of marsh elevation change with WARMER-2 across five regions of the San Francisco Bay Delta (Cache Yolo, South Delta, North Delta, Central Delta, and Suisun). The model was run across a range of initial elevations for each region and for scenarios of sea-level rise (30, 61, 91, 122, 152, 183, 305 cm by 2100), sediment availability (historic, constant, declining, and increase), and with and without a temporally dynamic tidal range. Results from the Delta Simulation Model 2 hydrodynamic model were used to calculate rates of tide range increase with sea-level rise. WARMER-2 was calibrated using soil cores from Callaway et al 2012 (Rush Ranch and Browns Island cores), and a soil core from Miners Slough. ...

This data release encompass numerous studies examining soil properties and greenhouse gas fluxes of Prairie Pothole Region (PPR) wetland catchments. The PPR is one of the largest wetland ecosystems in the world, encompassing approximately 770,000 square kilometers of the north-central U.S. and south-central Canada, with the U.S. portion including parts of Iowa, Minnesota, South Dakota, North Dakota, and Montana. The data included in this release span a 19-year period (1997–2016) and represent a diversity of studies ranging from localized (e.g., wetland catchments and complexes) to region-wide efforts that span the PPR’s climate and land-use gradient. Data from individual wetland catchments encompass a variety of...

The original distribution of the study species Physostegia correllii included freshwater floodplains of large rivers in the southcentral U.S. (Colorado, Rio Grande, Mississippi). Experiments to determine the effects of shading on P. correllii were conducted using short-term shade cloth treatments (full sunlight vs. 30% shading for 2-3 weeks). Mean height and cover responses of individuals were determined in conservation gardens located in Lafayette, Louisiana. Physostegia correllii plants were grown in shaded environments for 2.5 weeks.

These data are estimates of the proportional contributions of bearded seal, beluga whale, bowhead whale, and ringed seal to the diets of southern Beaufort Sea polar bears. Fat biopsy samples were collected from polar bears captured or biopsy darted along the north coast of Alaska or on offshore ice during March, April, and May from 2004 to 2016. Fatty acid data of the above four prey species were compiled from online sources (Bromaghin et al. 2015ab, USGS 2021) and one private source that has been used in several polar bear diet studies (Thiemann et al. 2008). Diet composition was estimated from polar bear adipose tissue fatty acid composition data (USGS 2023) using three methods: the original quantitative fatty...
This dataset contains sampling, molecular methods, and partial tRNA-Leu DNA sequence information for three individual Frullania nisquallensis.
There is a growing movement within natural resource management to view wildlife health as a cumulative outcome of many different factors, rather than simply the absence of disease. This inclusive understanding of health opens the door to management options that are more creative than traditional techniques to prevent or mitigate pathogens. The public health field uses a determinants of health framework to understand the physical, social, and cultural systems that impact health at the individual and community levels (National Academies of Sciences, Engineering, and Medicine 2016). Applying a similar framework to wildlife can help managers focus on tangible actions to positively impact wildlife health in the absence...

The “Glaciers of Glacier National Park Repeat Photography Collection” is a compilation of photographs documenting the retreat of glaciers in Glacier National Park, Montana, U.S.A. (GNP) through repeat photography. The collection is comprised of 57 image pairs, resulting from twenty-two years of U.S.Geological Survey (USGS) field excursions (1997-2019) for the purpose of photographically documenting glacier change. Historic images of glaciers were located at the USGS Photographic Library, GNP Archives, and the University of Montana Special Collections. Employees and volunteers of the USGS Repeat Photography Project relocated the site of each historic photograph and re-photographed the image to create a historic-contemporary...

Two summit sites were established in 2003 on Dancing Lady and Bison Mountain, east of the continental divide. Two additional summit sites were established in 2004 on Pitamakin and Mt. Seward, also east of the continental divide. These four summit sites comprise a target region set up in accordance with the Global Observation Research Initiative in Alpine Environments (GLORIA). GLORIA was initiated by the University of Vienna in 2000 and protocols for operating target regions have been refined and...
Metals are used in primary producer metabolic pathways, such as photosynthesis and the acquisition of macronutrients nitrogen (N) and phosphorus (P), yet we often do not know their potential as limiting nutrients in freshwaters. In the Great Lakes, metals have sometimes been identified as limiting the acquisition of macronutrients, mostly in off-shore waters that are relatively isolated from tributary inputs and sediment interactions. We hypothesized that another area where metals might be important was within harmful algal blooms (HABs). Harmful algal blooms are more likely to occur where N and P loads are elevated due to human activities, but short-term growth assays still often find summer bloom communities are...
