The Yukon North Slope is an arctic “hot spot” of climate change-induced effects with profound significance for the Inuvialuit and the larger region. In 1984, the Inuvialuit entered into a land claim agreement – the Inuvialuit Final Agreement (IFA) – with the governments of Canada, Yukon and Northwest Territories. A co-management body formed to make a plan, which was developed in 2003 but never ratified and is now considered out-of-date. Round River Conservation Studies is assisting WMAC(NS) in the collection, development and synthesis of spatial data, models and analyses of cultural and ecological values of the YNS.The project is a collaboration among the NWB LCC, Round River Conservation Studies, and the Arctic...

Climate change vulnerability assessments are commonly used to identify species or populations at risk from global climate change, but few translate impact assessments to climate change adaptation actions. Furthermore, most climate change adaptation efforts emphasize where to implement management actions, whereas timing remains largely overlooked. The rate of modern climate change introduces urgency in evaluating whether delaying conservation actions compromises their efficacy for reaching important conservation targets. We evaluated the importance of multiple climate change adaptation strategies including timing of actions on preventing extinctions for a threatened climate-sensitive species, the Eastern Massasauga...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

Streams across the world are highly fragmented due to the presence of in-stream barriers (e.g., dams and stream-road crossings), many of which restrict or block fish passage. Retrofitting or replacing these structures is a high priority for restoring habitat connectivity for native fishes and other aquatic organisms in the Pacific Northwest. The task of restoring habitat connectivity for problematic stream-road crossings is daunting given the many thousands of barriers that are present and the massive financial investments required. Further, the potential risks to road infrastructure from flooding, debris flows, and climate change will need to be addressed to ensure the best allocation of resources. In this study,...

The potential ecological and economic effects of climate change for tropical islands were studied using output from 12 statistically downscaled general circulation models (GCMs) taking Puerto Rico as a test case. Two model selection/model averaging strategies were used: the average of all available GCMs and the average of the models that are able to reproduce the observed large-scale dynamics that control precipitation over the Caribbean. Five island-wide and multidecadal averages of daily precipitation and temperature wereestimated by way of a climatology-informed interpolation of the site-specific downscaled climate model output. Annual cooling degree-days (CDD) were calculated as a proxy index for air-conditioning...

The 25,000 km of shoreline in southeast Alaska was surveyed for waterbirds by fixed-wing aircraft in summer and winter during the period 1997 to 2002. A ground/boat survey double sampled 20% of the summer habitat and 5% of the winter habitat to adjust and enhance the air survey. The most abundant species during the summer surveys, with visibility correction factors applied, were gulls (Larus spp.; 306,200, CV = 0.004), scoters (Melanitta spp.; 185,700, CV = 0.004), and Harlequin Duck (Histrionicus histrionicus; 34,640, CV = 0.03). The most abundant species observed during the winter surveys were goldeneyes (Bucephala islandica and B. clangula; 121,920, CV = 0.01), gulls (105,000, CV = 0.01), Mallard (Anas platyrhynchos;...

Governmental and nongovernmental organizations charged with managingnatural resources increasingly emphasize the need to work across jurisdictional boundaries.Their challenge is to manage shifting resources under rapidly changing climate andland-use scenarios. Scientists, resource managers, and conservation planners, and theirorganizations and agencies routinely collaborate on projects to solve specific problems.Cooperative frameworks to programmatically address complex social–environmental issuesand develop shared research, planning, and implementation priorities are relatively new.One such framework includes 22 Landscape Conservation Cooperatives that encompass the US, Caribbean countries, and bordering regions...

Conant et al. (1991) describe swan survey methods used by the U.S. Fish and Wildlife Service in Alaska and present the results of surveys using these methods. Full citation: Conant, B., J.I.

This 1996 publication by John I. Hodges, James G. King, Bruce Conant, and Henry A. Hanson summarized population abundance trends of waterfowl, loons, and sandhill cranes from data collected in the Alaska strata (i.e., strata 1-11) of the North American Waterfowl Breeding Population and Habitat Survey during 1957-1994. The authors also presented results of analyses that compared the detection rates of right- vs. left-seat observers (i.e., with vs. without piloting duties).

Throughout the Caribbean, conservation is ecologically, politically, and sociallychallenging due to a number of factors including globalization, climate change, loss ofbiodiversity, and the spread of invasive species. Relationships between organizations andinstitutions that govern the region’s natural and cultural resources are key to conservationsuccess as partners work to implement plans to meet science, capacity, and informationneeds. However, the complex challenges involved in conservation work and tenuous relationshipsamong organizations can result in a “knowing–doing gap”. Empirical evidencefrom 130 Caribbean conservation organizations indicates that barriers to bridging this gapare lack of information and...

This study quantitatively explores whether land cover changes have a substantive impact on simulated streamflow within the tropical island setting of Puerto Rico. The Precipitation Runoff Modeling System (PRMS) was used to compare streamflow simulations based on five static parameterizations of land cover with those based on dynamically varying parameters derived from four land cover scenes for the period 1953-2012. The PRMS simulations based on static land cover illustrated consistent differences in simulated streamflow across the island. It was determined that the scale of the analysis makes a difference: large regions with localized areas that have undergone dramatic land cover change may show negligible difference...

Wetlands in the remote mountains of the western US have undergone two massive ecological “experiments” spanning the 20th century. Beginning in the late 1800s and expanding after World War II, fish and wildlife managers intentionally introduced millions of predatory trout (primarily Oncorhynchus spp) into fishless mountain ponds and lakes across the western states. These new top predators, which now occupy 95% of large mountain lakes, have limited the habitat distributions of native frogs, salamanders, and wetland invertebrates to smaller, more ephemeral ponds where trout do not survive. Now a second “experiment” – anthropogenic climate change – threatens to eliminate many of these ephemeral habitats and shorten...

Existing stream temperature data will be compiled from numerous federal, state, tribal, and private sources to develop an integrated regional database. Spatial statistical models for river networks will be applied to these data to develop an accurate model that predicts stream temperature for all fish-bearing streams in the US portion of the NPLCC. Differences between model outputs for historic and future climate scenarios will be used to assess spatial variation in the vulnerability of sensitive fish species across the NPLCC.
