There is a need to understand how alteration of physical processes on the Rio Grande River have impacted aquatic biota and their habitats, and a need to predict potential future effects of climate change on biotic resources in order to prescribe research and management activities that will enhance conservation of aquatic species. We propose a project with the goal of developing monitoring recommendations and identifying research needs for aquatic ecological resources in the Big Bend region of the Rio Grande. This goal will be targeted by synthesizing and analyzing available data and literature for aquatic species in the project region. In particular, we will work to develop time series of abundance and population...

This project used species distribution modeling to assess the risk to habitat change under various climate change scenarios for rare plants. To predict the response of rare plant species to climate change, the project modeled the current distribution of the species using climate and environmental data (e.g., soils, disturbance, land-use), use these models to predict the species distribution given climate change, calculate current and future range size, calculate the amount of overlap of predicted future distribution with current distribution, and assess where barriers and protected areas are located with reference to the change in species distribution. Given the results of the distribution modeling, each species...

Rate of global biodiversity loss increased significantly during the 20th century associated with human environmental alterations. Specifically, mismanagement of freshwater resources contributed to historical and contemporary loss of stream-dwelling fish diversity and will likely play a role in determining the persistence of species in the future. We present a mechanistic pathway by which human alteration of streams has caused the decline of a unique reproductive guild of Great Plains stream-dwelling fishes, and suggest how future climate change might exacerbate these declines. Stream fragmentation related to impoundments, diversion dams and stream dewatering are consequences of increasing demand for freshwater resources...

We propose to use long-term fish-population data from a relict reach of the Pecos River, New Mexico to assess population dynamics of imperiled prairie-river minnows, including Arkansas River shiner. Development of viable management strategies requires basic understanding of population ecology. Rigorous, quantitative ecological methods can be used to analyze continuous, long-term demographic data, but such data are rarely available for imperiled, non-game fishes. Data available for the Pecos River provide a unique opportunity to apply quantitative methods to prairie-river minnow conservation and management. Analyses proposed here would determine (1) whether population regulation is density dependent or flow-regime...

The Imiq Hydroclimate Database houses hydrologic, climatologic, and soils data collected in Alaska and Western Canada from the early 1900s to the present. This database unifies and preserves numerous data collections that have, until now, been stored in field notebooks, on desktop computers, as well as in disparate databases. Synthesizing and analyzing the large-scale hydroclimate characteristics of this important climatic region have been made easier with this searchable database. The data, originally collected in a Microsoft SQL Server 2008 relational database, has been migrated to an open source PostgreSQL and PostGIS environment. The Imiq Data Portal provides public access to portions of the Imiq Hydroclimate...

There are many challenges in detecting precipitation trends in Alaska. The most substantial are the small number of observations, inhomogeneities, differences among gridded data sets, and differentiating between long-term trends and decadal variability. Analyzing both station and regional products will increase our understanding of where local trends in precipitation may differ significantly from regional trends, providing key information for developing better downscaled climate projections. These in turn, will provide insight into fine scale heterogeneity in climate change that may be important in determining the stability of key habitat features, such as wetlands and insect avoidance areas. As a by-product of...

The ShoreZone in the Classroom Curriculum Implementation project built upon the ShoreZone in the Classroom Pilot Networking Trip. Educational Consultant Marie Acemah liaised over email and in-person at the North Slope School District (NSBSD) Curriculum Camp in Barrow to develop Curricular Units that make ShoreZone available as an educational tool in NSBSD classrooms. This project resulted in two Units, specifically: 1) Coastal Ecosystems Unit; and 2) Documentary Filmmaking Summer Intensive Proposal. The ShoreZone tool is now available and accessible throughout the NSBSD district. The District and the Ilusagvik College are interested in partnering with ShoreZone to lead for-credit summer documentary film camps in...

LCC funding allowed completion of this BLM initiative to develop a North Slope-wide cover type map and create a crosswalk that integrates all component cover type maps that comprise the larger overall North Slope cover type map.This map is the outcome of a multi-year project to produce a moderate resolution landcover base map for the North Slope of Alaska to serve as a primary base layer for long-term science and planning activities on the North Slope. New Landsat Thematic Mapper (TM) 30 meter resolution landcover maps were produced for the far western arctic, and for the area between the National Petroleum Reserve - Alaska (NPRA) and Arctic National Wildlife Refuge. In the NPRA, an existing land cover map from...

The Beaufort Sea coast in Arctic Alaska and neighboring northern Canada has recently experienced extreme and accelerated climate change, including a dramatic reduction in summer sea ice. Human systems will likely be impacted through changes to oil industry and community infrastructure currently in place along parts of the coast, to habitat availability for harvested species such as caribou, waterbirds, and anadromous fish, to culturally important landscape elements, and to both recreational and subsistence coastal access. We used literature review and structured interviews to 1) identify current, broad interests for ongoing coastal research in the arctic, 2) identify the best mechanisms and format for communicating...

The Nature Conservancy (TNC) drew upon its existing Canadian network to coordinate with potential Canadian partners on behalf of the Arctic LCC. TNC addressed the Arctic LCC’s need to identify specific overlapping goals, objectives and geographic interest between the Arctic LCC and those potential partners. TNC provided information about the Arctic LCC to potential Canadian partners; initiated contact and helped build relationships with those potential partners; they summarized current and planned climate-related work and other areas of overlapping interest with the Arctic LCC, and identified the top six to eight most appropriate potential Canadian partners with which the Arctic LCC should engage.

Information on the nature and distribution of permafrost is critical to assessing the response of Arctic ecosystems to climate change, because thawing permafrost under a warming climate will cause thaw settlement and affect micro-topography, surface water redistribution and groundwater movement, soil carbon balance, trace gas emissions, vegetation changes, and habitat use. While a small-scale regional permafrost map is available, as well as information from numerous site-specific large-scale mapping projects, landscape-level mapping of permafrost characteristics is needed for regional modeling and climate impact assessments. The project addresses this need by: (1) compiling existing soil/permafrost data from available...

The Terrestrial Environmental Observation Network (TEON) is intended to meet the need for a sustainable environmental observing network for northern Alaska. The TEON plan proposes collection of a time series of specific environmental variables in seven representative watersheds across northern Alaska. The Kuparuk River watershed is central to this plan both because of its location that bisects Alaska’s North Slope and its record of hydroclimatic data and research now surpassing 30-yrs. Nested catchments within and adjacent to this sentinel Arctic river system integrate climate and landscape responses from the Brooks Range foothills (Imnavait Creek and Upper Kuparuk River) to the Arctic Coastal Plain (Putuligayuk...

Of the vital rates that determine recruitment, breeding propensity (i.e., the proportion of females that lay at least one egg) and nest success appear to have the greatest influence, but breeding propensity remains poorly studied. The few studies that have been conducted reveal it to be highly variable among years (15–77%), likely in response to environmental conditions (e.g., precipitation and wetland availability), and lower than estimates from other dabbling ducks. Thus, quantifying breeding propensity across the mottled duck range in the WGC and identifying factors responsible for its variation remain high priorities for future investigation. Breeding propensity is also among the most difficult vital rates to...
