Data

Dataset contains sampling information (site, location, and date of sampling) for largemouth bass and silver carp captured in La Grange Pool of the Illinois River during 2015 used to determine the population size structure of both species for analyzing size-specific feeding of largemouth bass on young-of-year and Age-1 silver carp. The dataset also contains information on fish prey items...

This dataset uses the ITIS recommended Ortmanniana pectorosa, Conrad, 1834 in place of Actinonaias pectorosa, which was used in the Richard et al. 2020 manuscript. Biologists monitoring freshwater mussel (Order Unionida) populations rely on behavioral, often subjective, symptoms to identify “sick” or stressed animals, such as gaping valves and slow response to probing and lack clinical...

Topobathy was surveyed during the fall of 2022 for two locations along Minnesota Point, where past beach nourishment (dredge materials) were placed. These topobathymetric surveys of Minnesota Point and Lake Superior are repeat surveys that will be used evaluate movement of placed material and overall change of near-shore bathymetry. The data was acquired using a lidar sensor, and single...

Nutrient reduction on the landscape scale often focuses on actions that reduce the movement of nitrogen (N) and phosphorus (P) from agricultural lands into streams and rivers. However, processing of N and P in streams and rivers can be substantial and increasing these in-stream processing rates could result in reductions or transformations of nutrients to less labile or less mobile forms...

This repository contains the data, code for modeling and analysis, and publication markdown documents for a comparison of various methods for fitting multi-state models, including maximum likelihood and Bayesian approaches via R.

The long decline of the eastern migratory population of monarch butterflies (Danaus plexippus) appears to have abated in recent years and the population now persists at a much-reduced abundance. Stochastic variation in abundance typical of monarch butterflies, and other insects, places this population at heightened risk of quasi-extinction, a level of abundance below which recovery of...

Legacy contaminants and contaminants of emerging concern (CECs) were assessed in tree swallow (Tachycineta bicolor) tissue and diet samples from three drainages in the Milwaukee Estuary, Wisconsin to understand exposures and possible effects.

The Deepwater Horizon oil spill caused extensive injury to natural resources in the Gulf of Mexico, and Gavia immer (common loon) were negatively affected from the spill. The Open Ocean Trustee Implementation Group funded the project Restoration of Common Loons in Minnesota to restore common loons lost to the spill. In 2020–21, study lakes in an eight-county region in north-central...

This model archive contains files for a set of groundwater flow, particle tracking, and management optimization models that simulate the area around the Navy-Northrop-Grumman contamination plume on Long Island, New York. These models were developed as in insets from the Long Island Regional “parent” Model, from which perimeter boundary conditions were inherited. In addition to input and...

This code describes graphical and analytical comparisons between monarch butterfly survey data collected during summer breeding, fall migration, and winter.

Forest canopy gap metrics for select floodplain forest canopy gaps in the Upper Mississippi River System (UMRS).

Over the summer of 2020, the Illinois Waterway (IWW) was closed to complete maintenance on lock chambers along the Illinois River. This closure restricted vessel traffic along the river and potentially changed habitat characteristics for aquatic vegetation establishment and growth. To assess if patterns of vegetation establishment and growth changed during the closure, peak biomass...
