This product contains the transcribed count data from the Alaska Izembek Winter Brant Survey. These data were produced from transcribed georeferenced voice recordings using customized software developed by John Hodges (Program Record, Program Transcribe).

Annual summary reports of Red Knot breeding ecology studies on the Seward Peninsula since 2011.
The primary objectives of this study were twofold. The first was to configure an established public domain particle trajectory model (General NOAA Oceanographic Modeling Environment – GNOME) (NOAA Hazardous Materials Response and Assessment Division – web site) location file representing the oceanographic settings surrounding the Aleutian Chain and use it to numerically explore the threat of disabled ships grounding on or near sensitive environmental habitats.The products of this phase of the study will be a working model of the region, loaded with approximately three years of realistic potential scenarios, and a large data base archive of greater then 3 million “pseudo ship” trajectories each of 7 days duration....
Interesting information. Can we update yet? Yes, this record has been updated.
Accidental introductions of rodents present one of the greatest threats to indigenous island biota. On uninhabited remote islands, such introductions are most likely to come from shipwrecks. Here we use a comprehensive database of shipwrecks in Western Alaska to model the frequency of shipwrecks per Aleutian and Bering Sea island, taken as a proxy for the likelihood of rodent introductions, using physical variables, and the intensity of nearby fishing traffic and activity as predictors. Using data spanning from 1950 to 20114, we found that shipwrecks were particularly common in the 1980s to early 2000s, with a major peak in wrecks during the late 1980s. Amount of fishing activity within 5 km of an island was the...
Northwest Boreal Landscape Conservation Cooperative (NWB LCC) partners are working to collectively design a sustainable future for the people, cultures, and ecosystems in the region. To begin this difficult task, the partners asked for a review and synthesis of existing natural resource management plans, covering both countries and all four states, provinces and territories. The NWB LCC Steering Committee believes that it is important to both be in alignment with current goals and objectives for land and resources, and to build on the work already completed by agencies, organizations and research institutions. The review summarized and synthesized 120 management plan goals within the NWB LCC geography. Goals and...
Interesting information.
Boreal ecosystems are inherently dynamic and continually change over decades to millennia. The braided rivers that shape the valleys and wetlands continually change course, creating and removing vast wetlands and peatlands. Glacial melt, erosion, fires, permafrost dynamics, and wind-blown loess are among the shaping forces of the landscape. As a result, species interactions and ecosystem processes are shifting across time. The purpose of this book is to create a resource for regional land and resource managers and researchers by synthesizing the latest research on the (1) historical/current status of landscape-scale drivers (including anthropogenic activities) and ecosystem processes, (2) future projected changes...
When climate change disrupts a village, city, state, or province, how do leaders respond? What unexpected obstacles do they run into? Researchers from the University of Saskatchewan want to know what factors are conducive to communities adapting to climate change. They also want to better characterize exactly what impedes progress. The team is investigating different models of adaptation ranging from top-down government planning to grassroots organization. Specifically, the team will compare communities in Yukon Territory and Alaska to show how different jurisdictions respond to change. They’re developing a framework to provide communities and planners new tools to chart their future. The team is beginning by identifying...
The geodiversity approach uses topography to define landscape features. Topography can be a proxy for ecological function. For example, topography influences the solar radiation available for plants and animals, the soil characteristics through the likelihood for erosion and deposition, and the characteristics of hydrologic features. Therefore, similar geodiversity types should have the potential for similar ecological function even as the climate changes. We classified the landscape into three topographic feature categories: canyons, ridges, and slopes. Each topographic feature was then clustered into distinct geodiversity types. Slopes were clustered into groups using elevation, slope angle, and yearly solar radiation....
