The Integrated Ecosystem Model (IEM) for Alaska and Northwest Canada Project integrated existing models of vegetation, disturbance, and permafrost into one complete ecosystem model for the state of Alaska and Northwest Canada.The final synchronized model will integrate existing climate, vegetation, disturbance, hydrology, and permafrost models to improve understanding of potential landscape, habitat and ecosystem change. The project’s (September 1, 2011 through August 31, 2016) primary goal was to develop the IEM modeling framework to integrate the driving components for and the interactions among disturbance regimes, permafrost dynamics, hydrology, and vegetation succession/migration for Alaska and Northwest Canada....

In the drier, mid- and low-elevation portions of the Southern Rockies LCC, Fremont cottonwood represents the only native vegetation of tall stature, and cottonwood-dominated woodlands provide critical habitat for a large array of neotropical migratory birds and other animals. These woodlands likely dominated alluvial reaches of all streams where a snowmelt-driven spring flood was the major factor driving geomorphic and vegetation dynamics. These woodlands were also among the first habitats to undergo transformation as the regions land and water resources were developed.The PI coauthored a paper (Andersen et al. 2007) on assessing the amount of native Fremont cottonwood forest remaining on floodplains in 26 subbasins...

To elucidate these potential “bottom up” effects of climate changes to Arctic ungulates and evaluate the trophic mismatch hypothesis, the Arctic Landscape Conservation Cooperative (ALCC), the Bureau of Land Management (BLM), the U.S. Geological Survey (USGS), Teck, Inc., and the National Park Service provided funding in 2012-14 to incorporate the calving and summer range of the Western Arctic caribou herd (WAH) into an ongoing inter-agency research and monitoring effort to examine the influences of climate change on the nutrient dynamics of caribou forages. This work is leveraging existing projects on the North Slope of Alaska that are primarily funded through the USGS Changing Arctic Ecosystems Initiative. Field...

More information is needed about species composition, abundance, or distribution of the microfauna and meiofauna living within the interstitial spaces of the littoral zones along the Beaufort Sea coast. Shorebirds depend on meiofauna for food for pre-migratory fattening and these organisms make important contributions to bioremediation of oil spills.The information obtained from this jointly-funded research can contribute to development of mitigation measures and strategies to reduce potential impacts from post-lease exploration and development. This information need extends to the lower trophic levels forming the base of these complex food webs and the biochemistry that influences these relationships. Their contributions...
This project used species distribution modeling, population genetics, and geospatial analysis of historical vs. modern vertebrate populations to identify climate change refugia and population connectivity across the Sierra Nevada. It is hypothesized that climate change refugia will increase persistence and stability of populations and, as a result, maintain higher genetic diversity. This work helps managers assess the need to include connectivity and refugia in climate change adaptation strategies. Results help Sierra Nevada land managers allocate limited resources, aid future scenario assessment at landscape scales, and develop a performance measure for assessing resilience.

The project will complete an extensive mapping of coastal change along the entire coastline of the Western Alaska Landscape Conservation Cooperative (LCC). The work will provide important baseline information on the distribution and magnitude of landscape changes over the past 41 years. The extent of change to the coastline and to coastal features, such as spits, barrier islands, estuaries, tidal guts and lagoons, is known to be substantial in some areas along the coast (e.g., portions of the Yukon–Kuskokwim Delta), although the extent of change along the full Bering Sea coast is not well documented. With this analysis, changes can be summarized for different land ownerships or other units to assess the extent of...

Colorados Front Range represents a region of the Southern Rockies LCC that is both ecologically and economically significant. It is home to the majority of Colorados residents, including the major population centers of Denver, Fort Collins, Boulder, and Colorado Springs, and provides critical ecosystem services such as clean and abundant water, wildlife habitat, recreation opportunities, and aesthetic values to the rest of the state. Ponderosa pine (Pinus ponderosa) dominated forests span the majority of the Front Range mountains and foothills, covering approximately 700,000 acres of the Front Range landscape between 5000 and 8500 ft elevation. The lower-montane zone ponderosa pine forests (~5500-7000 ft) form the...

In the desert Southwest, changes in species composition, abundance, and distribution that may occur with climate change have significant implications for management of natural resources. These changes include: the extirpation or introduction of species, losses of biodiversity, shifts in structure and function of ecosystems and the services they provide, changes in wildlife habitat, invasion of non-native species, and changes in fire regimes. For planning, mitigation, and adaption, land managers would be greatly aided by knowing, in advance, which plant species, functional types, and assemblages will change in response to climate change so that monitoring and mitigation measures can focus on those resources. FY2012In...

This project is focused on establishing a statewide framework to improve the hydrography mapping and stewardship in Alaska. This will be acheived through the creation of a statewide system to make digital mapping data updates accessible and affordable, and through the creation of a statewide hydrography mapping coordinator position to synchronize updates and guide hydrography mapping development. This framework will allow agencies and organizations to greatly improve their hydrography mapping data, as well as consume and uplift project level hydrography data that would not otherwise be incorporated.

Viable sockeye salmon populations are critical to the economy, culture, and freshwater ecosystems of Bristol Bay in Western Alaska, and it is unclear how populations might respond to warming temperatures during the critical life history stages of spawning and embryo incubation. The overarching goal of the project is to understand how temperature might influence population-specific patterns of embryo incubation, timing of hatching and fry emergence, and sockeye salmon embryo survival. By combining analyses of data from two large lake systems in the Kvichak watershed, laboratory rearing experiments to elucidate functional relationships, and simulation modeling, this project quantifies biological responses to changing...

The Alaska Trumpeter Swan Survey used U.S. Geological Survey (USGS) 1:63,360 scale quadrangle maps as sampling units (plots). USGS identifies each 1:63,360 map with a combination of two identifiers: 1) the 1:250,000 quadrangle in which it occurs, and 2) the 1:63,360 quadrangle map itself. Similarly, in the swan survey files, the 1:63,360 map is identified by the combination of the “Map” and “Quad” fields. The Map field identifies the 1:250,000 quad by its USGS numeric code; the Quad field identifies the 1:63.360 map by its appropriate letter-number. USGS_Map_Index.tif is a map version of the USGS map index, saved in an image format (.tif).

This project supports the technical development of a mobile application for identifying and reporting invasive plant species in Alaska. It will result in a portable, digital version of a field guide that can be easily updated and that supports integration of reports into the Alaska Exotic Plants Information Clearinghouse (AKEPIC). Under development for both Android and iOS operating systems, the app has the potential to increase the public’s knowledge of invasive plants, as well an improve opportunities for reporting new occurrences. See also project WA2014_33.

The purpose of this agreement is to initiate SRLCC-wide data discovery, cataloging, and general GIS analysis to characterize the landscape across the SRLCC geographic area. The SRLCC has identified the need for a data management activity to support all aspects of data discovery, dissemination, cataloging, and analysis. An existing agreement between FWS and the USGS provides for an SRLCC catalog inside the U.S. Geological Survey-sponsored ScienceBase scientific data and information management platform and provides the ability for partner organizations to maintain and contribute to this work environment. Initial information and data discovery process will compile existing resources in the ScienceBase SRLCC data portal...
Research on coastal change in Western Alaska has increased rapidly in recent years, making it challenging to track existing projects, understand their cumulative insights, gauge remaining research gaps, and prioritize future research. This project will identify existing coastal change projects in Western Alaska and synthesize information about each project. The resulting report will document the project landscape for communities facing change, decision-makers navigating change, researchers pursuing projects, as well as funding agencies trying to prioritize where to allocate resources.

There is currently have a very poor understanding of how climate change will affect food web structure and mercury accumulation in lakes on the Arctic Coastal Plain of Alaska. In this study, researchers are addressing this knowledge gap by adopting a space-for-time approach. Fish and food web ecology, and mercury accumulation patterns, are being investigated in several lakes that represent a gradient in temperature/ice phenology of up to two ice-free weeks and 10°C. They are also comparing food web structure and rates of mercury biomagnification among the lakes, and relating these to several climate variables. Finally, they are relating past trends in mercury accumulation in lake sediments to indices of lake productivity...

Streamflows in late spring and summer have declined over the last century in the western U.S. and mean annual streamflow is projected to decrease by six to 25% over the next 100 years. In arid and semi-arid regions of the western US, it is likely that some perennial streams will shift to intermittent flow regimes in response to climate-driven changes in timing and magnitude of precipitation, runoff, and evaporation. The project will address the following two research question: how will small stream (1st-3rd order) low flow hydrology be impacted by predicted longer, drier summers in the Upper Colorado River Basin under climate change and in turn, what will be the resulting impacts on riparian plant communities?...
