Estimated number of breeding pairs of Horned lark based on the amount of grass, trees, and/or hay in the landscape. Landscape scale varied from 1/4- to 2-mile radius depending on the species. Pair estimates were calculated for grass patches >=1 ha, extrapolated to 40-ac cells, then smoothed by averaging over a 1-mile radius. Models were based on point count surveys conducted in 2003-2005 throughout the Tallgrass Prairie Pothole Region. Point count locations were stratified by cover type, the amount of grass in the landscape, and USFWS Wetland Management District boundaries. Landcover data were derived from 2000 Thematic Mapper imagery. Grid values = number of breeding pairs per 30-m pixel.

We used in situ nutrient diffusing artificial substrates (NDS) to test for nutrient limitation of benthic algae. Concentrated nutrients are enclosed in vials with diffusive fritted glass tops, which allow nutrients contained in an agar gel to slowly leach through the substrates. Periphyton accumulates on diffusive surfaces when NDS are deployed in natural waters, and differences in accumulation rates between nutrient treatments and controls are interpreted as evidence of periphyton nutrient limitation. The NDS data are original, whereas the associated ambient data have been previously released in Brightbill and Frankfurter (2010) and Mebane and others (2014), and are repeated here for convenience References Brightbill,...

This dataset records Cladophora and associated submerged aquatic vegetation (SAV) biomass collected approximately monthly during the growing season starting in 2018 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting data include: - seasonal time series of light, water currents, wave action, temperature, specific conductivity, turbidity, pH, phycocyanin, chlorophyll, and dissolved oxygen from moored sensors at a subset of stations; - measurements of Secchi disk depth and water chemistry; - water column profiles of temperature, specific conductivity, turbidity, pH, phycocyanin,...
River Conservation Opportunity Areas represent areas of the state where organizations and individuals working on the conservation of SGCN and their habitat would be most likely to successfully implement the conservation actions summarized in the Wildlife Action Plan for taxonomic and natural community groups. Providing information to help people make decisions about “where” to implement conservation actions is an important related aspect of conservation actions. Although most COAs have been given boundaries, they are indeed “fuzzy”, meaning their application can vary considerably according to context or conditions and they are not fixed or definitive—they will move, depending on the objectives.

Conservation Opportunity Areas are places in Illinois: with significant existing or potential wildlife and habitat resources; where partners are willing to plan, implement, and evaluate conservation actions; where financial and human resources are available; and where conservation is motivated by an agreed-upon conservation purpose and set of objectives.To create a list of places in the state fitting this description, scientists with Illinois Natural History Survey identified priority areas for conservation, using a variety of tools, such as Audubon’s Important Bird Areas and The Nature Conservancy’s portfolio sites. The centerpiece of their analyses, however, was a dataset showing the state’s key blocks of habitat...

The Wildlife Action Network is composed of mapped terrestrial and aquatic habitats, buffers, and connectors that represent a diversity of quality habitats that support Species in Greatest Conservation Need (SGCN). The Network is made up of mapped habitat representing viable or persistent populations and “richness hotspots” of Species in Greatest Conservation Need (SGCN). Added to this information are other data on the relative condition of habitat including spatially prioritized and connected Sites of Biodiversity Significance, Lakes of Biological Significance, and Streams with “exceptional” Indices of Biological Integrity. Consideration should be given to projects or activities that could result in the loss, degradation...

Bottomlands of large rivers within the Mississippi River Basin. Derived by combining the Mississippi alluvial plain with natural floodplains created by the Scientific Assessment and Strategy Team for the Upper Mississippi, and statewide floodplain coverages where available. While the Mississippi alluvial plain is not entirely bottomland (e.g. Crowley's Ridge), excluding these non-bottomland areas from analysis would exclude opportunities to expand existing forest patches and enhance connectivity. NOTE: Floodplain coverage in Arkansas, Louisiana, Mississippi, and Missouri is incomplete due to incomplete data availability as of October 2016.

Abstract (from http://www.nrcresearchpress.com/doi/abstract/10.1139/cjfas-2014-0517#.VSwd3Y7F8qZ): Seasonal degradation of aquatic habitats from hypoxia occurs in numerous freshwater and coastal marine systems and can result in direct mortality or displacement of fish. Yet, fishery landings from these systems are frequently unresponsive to changes in the severity and extent of hypoxia, and population-scale effects have been difficult to measure except in extreme hypoxic conditions with hypoxia-sensitive species. We investigated fine-scale temporal and spatial variability in dissolved oxygen in Lake Erie as it related to fish distribution and catch efficiencies of both active (bottom trawls) and passive (trap nets)...

An interdisciplinary and multiagency study was completed to understand harmful algal bloom dynamics by describing the spatial and temporal patterns and drivers of phytoplankton community structure and cyanotoxin and cyanotoxin-gene concentrations in Lake Okeechobee and Okeechobee Waterways in South Florida. The Waterway includes the Caloosahatchee and St. Lucie Rivers which drain the lake westward to the Gulf of Mexico and eastward to the Atlantic Ocean, respectively. Algae and cyanobacteria play crucial roles in aquatic ecosystems, but under favorable environmental conditions certain taxa experience population growth booms resulting in harmful algal blooms. Cyanobacteria are considered the most common bloom-formers...

This product consists of two tabular datasets and associated metadata for major phosphorus fluxes including manure and fertilizer inputs, crop uptake, as well as waste water treatment facility effluent and river export. These are time series data representing water years 1992 to 2012 for watersheds associated with the National Water Quality Program Surface Water Trends project. Dataset 1: Major fluxes and estimated net P balances. Dataset 2: Results of a t-test to determine if site level mean agricultural P balances were significantly above, not different, or below zero. Each site was then assigned to an Accumulation, Equilibrium, or Depletion status categories, respectively. Identification of sites where river...
