This data set includes a dropped-edge analysis of grassland and forest networks in the South Central United States based on land cover data from 2006 and graph theory to evaluate Landscape Resistance to Dispersal (LRD). LRD represents the degree to which habitat availability limits species movement. LRD decreases as habitat availability increases and increases as habitat availability decreases. This data set includes a range of LRD thresholds to represent species with different dispersal abilities and responses to landscape structure. A threshold indicates the highest LRD that still allows dispersal by a particular group of species. LRD thresholds are included in the data set, with low values representing connectivity...

This GIS dataset is the primary data product produced for the NW Climate Science Center-funded project, "Rangewide climate vulnerability assessment for threatened Bull Trout" (FRESC Study ID 851). We used predictions of temperatures in streams across approximately two-thirds of the species' range in the U.S. to map coldwater streams or “patches” suitable for spawning and early rearing of Bull Trout. Each patch consists of streams with contiguous reaches of cold water. Patches were delineated using medium resolution National Hydrography Dataset streams containing modeled temperatures available at 1 km intervals, as provided by the NorWeST project (http://www.fs.fed.us/rm/boise/AWAE/projects/NorWeST.html).Once the...

We used land cover projections for 2011 and 2050 of two scenarios derived from the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenarios (SRES). Scenario A1B emphasizes economic growth with a global orientation and scenario B2 focuses on environmental sustainability with a regional view. Our study area included counties within the southern Great Plains ecoregion in Oklahoma, Texas, and New Mexico. We calculated changes in landscape connectivity (dECA) between 2011 and 2050 for different species groups and landscape scenarios. We also calculated changes in habitat suitability (dA). We assessed the degree to which changes in landscape connectivity were influenced by changes in grassland...

This dataset represents results from this study attributed to the Hydrologic Unit Code (HUC) 12 watershed boundaries. Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the region’s streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage streams for current impacts and future changes, managers need region-wide information for decision-making and developing proactive management strategies. Our project met that need by integrating results...

High-resolution river centerlines vector shapefiles has 50 large rivers across the world. This high-resolution layer was generated will enable researchers to identify accurate river length, from headwaters to delta. The polylines could be used in coordination with any satellite-derived environmental or landscape variables for ecological research.

This dataset provides shapefile of outlines of the 68 lakes where temperature was modeled as part of this study. The format is a shapefile for all lakes combined (.shp, .shx, .dbf, and .prj files). This dataset is part of a larger data release of lake temperature model inputs and outputs for 68 lakes in the U.S. states of Minnesota and Wisconsin (http://dx.doi.org/10.5066/P9AQPIVD).

Temperate lakes may contain both coolwater fish species such as walleye (Sander vitreus) and warmwater species such as largemouth bass (Micropterus salmoides). Recent declines in walleye and increases in largemouth bass populations have raised questions regarding the future trajectories and appropriate management actions for these important species. We developed a thermodynamic model of water temperatures driven by downscaled climate data and lake specific characteristics to estimate daily water temperature profiles for 2148 lakes in Wisconsin, USA under contemporary (1989-2014) and future (2040-2064 and 2065-2089) conditions. We correlated contemporary walleye recruitment success and largemouth bass relative abundance...

The California Coast has hundreds of tree groves where dual management practices aim to reduce the risk of fire and to conserve habitat for overwintering monarch butterflies. As the climate changes, longer high-intensity droughts can increase mortality and/or limb loss in grove trees which causes an accumulation of fire-prone fuels. Moreover, these trees provide the critical habitat for overwintering monarch butterflies. Every year only certain trees in certain groves accumulate clusters of thousands of monarch butterflies. Should trees die or important roosting branches collapse, monarchs may not return in the future. The overall goal of this project is to understand how the dual management goals of fire management...

In partnership with South Atlantic Landscape Conservation Cooperative members, we assessed current and projected connectivity for three species that inhabit bottomland hardwoods throughout the southeastern US: black bear (Ursus americanus), Rafinesque’s big-eared bat (Corynorhinus rafinesquii), and timber rattlesnake (Crotalus horridus). For each species, we mapped important habitat connections between core patches of habitat using three different modeling approaches (Connectivity Analysis Toolkit (CAT), Circuitscape, and Linkage Mapper) that incorporated three types of resistance layers (expert opinion, niche modeling, and empirical data for the black bear only). The result was 21 sets of important connections,...

Vegetation transformations after wildfires are a growing issue for forest and shrubland managers in the Inland Pacific Northwest. Severe fires combined with persistent drought and invasive species can slow or prevent the recovery of burned forests and shrublands to their pre-fire states, resulting in ecological, economic, and cultural losses. Forests may be converted to shrub fields or grasslands, and shrublands may be replaced by invasive grasses. While shrublands and grasslands can be important components of these ecosystems, there is growing concern about the increased extent of these vegetation types on the landscape. Despite the severe post-fire vegetation transformations, little is known about where, when,...

Climate change has been shown to influence lake temperatures globally. To better understand the diversity of lake responses to climate change and give managers tools to manage individual lakes, we modelled daily water temperature profiles for 10,774 lakes in Michigan, Minnesota and Wisconsin for contemporary (1979-2015) and future (2020-2040 and 2080-2100) time periods with climate models based on the Representative Concentration Pathway 8.5, the worst-case emission scenario. From simulated temperatures, we derived commonly used, ecologically relevant annual metrics of thermal conditions for each lake. We included all available supporting metadata including satellite and in-situ observations of water clarity, maximum...

This shapefile contains polygons representing the current range of twelve ecosystems in the southeastern U.S. and the Caribbean. These were the focal ecosystems for the research project. The polygons were created by digitizing a representative area that contained each ecosystem's extent, as defined from GAP land cover or NatureServe's National Map land cover data.
