This publication is a product of the project "A Land of Flowers on a Latitude of Deserts: Aiding Conservation and Management of Florida’s Biodiversity".
Abstract (from http://www.springerplus.com/content/3/1/589): The growing quality and availability of spatial map layers (e.g., climate, geology, and land use) allow stream studies, which historically have occurred over small areas like a single watershed or stream reach, to increasingly explore questions from a landscape perspective. This large-scale perspective for fluvial studies depends on the ability to characterize influences on streams resulting from throughout entire upstream networks or catchments. While acquiring upstream information for a single reach is relatively straight-forward, this process becomes demanding when attempting to obtain summaries for all streams throughout a stream network and across...

Abstract (from http://www.nrcresearchpress.com/doi/abs/10.1139/cjfas-2013-0535#.VC1mIPldXOE): Cold-water habitat in lakes is projected to decrease under future climate scenarios, and existing trends suggest such declines are already impacting cold-water fish populations. Herein, we predict the effects of future climate and land use change on cold-water fish habitat in the glacial lakes of the upper midwestern US. Ecoregion-specific, regional regression models were developed to predict annual phosphorus loading rates to lakes based on land use and hydrology and coupled to a previously developed fish habitat model. Outputs from one land use change model and three global climate models were then used to project future...

Abstract (from http://onlinelibrary.wiley.com/doi/10.1002/eap.1389/full): Woody plant encroachment and overall declines in perennial vegetation in dryland regions can alter ecosystem properties and indicate land degradation, but the causes of these shifts remain controversial. Determining how changes in the abundance and distribution of grass and woody plants are influenced by conditions that regulate water availability at a regional scale provides a baseline to compare how management actions alter the composition of these vegetation types at a more local scale and can be used to predict future shifts under climate change. Using a remote-sensing-based approach, we assessed the balance between grasses and woody plants...

The Sea Surface Temperature (SST) data of the nearshore region of the North Pacific show temperature ranges in degrees C using points whose locations correspond to the centroids of AVHRR Pathfinder version 5 monthly, global, 4 km data set (PFSST V50). The pathfinder rasters are available from the Physical Oceanography Distributed Active Archive Center (PO.DAAC), hosted by NASA JPL. The data points in this dataset lie within a 20 km buffer from the GSHHS (Global Self-consistent, Hierarchical, High-resolution Shoreline) coastline. The GSHHS vector data are available from the National Geophysical Data Center (NGDC). Furthermore, each point in the SST dataset is categorized by the ecoregion in which it is located. This...
The American Fisheries Society and the Human Dimensions Research Unit of Cornell University have been engaged by NCCWSC to lead 5-year reviews of the CSCs. The purpose of the CSC review and evaluation is to: 1. Evaluate the effectiveness of each CSC in meeting project goals. 2. Assess the level of scientific contribution and achievement at each CSC with respect to climate modeling, climate change impacts assessments, vulnerability and adaptation of fish, wildlife and their habitats, and collaborative development of adaptation strategies for regional stakeholders, and education and training of graduate and post‐doctoral fellows 3. Evaluate the competencies and efficiencies of each host university in managing...

The Climate Adaptation Science Center (CASC) Network has chosen the emerging climate science field of Ecological Drought as a research focus area. The U.S. Affiliated Pacific Islands (USAPI) falls within the domain of the Pacific Islands CASC. This workshop was an add-on to the eight Ecological Drought Workshops (each hosted by a different CASC), so that additional attention could be directed towards the topic of drought in island environments, and the unique challenges that drought poses to island communities.
At present, inland fisheries are not often a national or regional governance priority and as a result, inland capture fisheries are undervalued and largely overlooked. As such they are threatened in both developing and developed countries. Indeed, due to lack of reliable data, inland fisheries have never been part of any high profile global fisheries assessment and are notably absent from the Sustainable Development Goals. The general public and policy makers are largely ignorant of the plight of freshwater ecosystems and the fish they support, as well as the ecosystem services generated by inland fisheries. This ignorance is particularly salient given that the current emphasis on the food-water-energy nexus often...

The “Sea‐Level Affecting Marshes Model” (SLAMM) is a moderate resolution model used to predict the effects of sea level rise on marsh habitats (Craft et al. 2009). SLAMM has been used extensively on both the west coast (e.g., Glick et al., 2007) and east coast (e.g., Geselbracht et al., 2011) of the United States to evaluate potential changes in the distribution and extent of tidal marsh habitats. However, a limitation of the current version of SLAMM, (Version 6.2) is that it lacks the ability to model distribution changes in seagrass habitat resulting from sea level rise. Because of the ecological importance of SAV habitats, the US Environmental Protection Agency, US Geological Survey, and US Department of Agriculture...

Quaking aspen populations are declining in much of the West due to altered fire regimes, competition with conifers, herbivory, drought, disease, and insect outbreaks. Aspen stands typically support higher bird biodiversity and abundance than surrounding habitat types, and maintaining current distribution and abundance of several bird species in the northern Great Basin is likely tied to the persistence of aspen in the landscape. This project examined the effects of climate change on aspen and associated bird communities by coupling empirical models of avian-habitat relationships with landscape simulations of vegetation community and disturbance dynamics under various climate change scenarios. Field data on avian...

This project built on an existing regional conservation partnership to use the most recent downscaled climate model projections to forecast the likely impacts of climate change to species and ecosystems in the Lower Mississippi Valley (LMV). The objective of this work was to develop and test ecological and biological models to facilitate regional adaptive management of wildlife resources and the forest and wetland ecosystems that support them in the LMV. The modeled projections were then used to evaluate climate change effects on high priority bird species, waterfowl, amphibians, and fisheries. In particular, the researchers sought to answer two key questions: (1) what are the impacts of predicted climate change...

This project produced land use change change forecasts for the United States at the national scale, based on the National Land Cover Dataset (NLCD) 2001. Both urban and agricultural expansion were modeled at 300-meter resolution at ten-year intervals from 2010 to 2050.

The goal of the glacial lakes regional study was to predict the impacts of climate and land use change on coldwater fish habitat in the glacial lakes region, which covers most of Minnesota, Wisconsin, and Michigan. The study includes both top-level, regional analyses and more detailed case studies of individual lakes. The goal of this project was to provide (1) projections of land use and climate change impacts on the trophic status of Midwestern coldwater glacial lakes, (2) projections of land use and climate change impacts on the regional distribution of coldwater lake oxythermal habitat, and (3) guidance on the types of coldwater lakes in which locations will be the most or least vulnerable to land use and climate...

The San Francisco Bay estuary contains the largest remaining expanse of tidal salt marshes in the western U.S. These marshes are home to a variety of federal and state protected species, such as the California clapper rail, California black rail, and the salt marsh harvest mouse. The estuary is also located on the Pacific Flyway, and is an important site for migrating and wintering birds. As climate conditions change, these salt marshes face a number of threats, including accelerated rates of sea-level rise, shifting precipitation, erosion, and more frequent and intense storms. Seas in the San Francisco Bay estuary have been rising 2.2 centimeters per decade, and could rise by as much as 1.24 meters by 2100, according...
