說明
Through the Changing Arctic Ecosystems initiative, the U.S. Geological Survey (USGS) strives to inform key resource management decisions for Arctic Alaska by providing scientific information on current and future ecosystem response to a warming climate. Our research is (1) examining critical physical and landscape-scale changes in the environment; (2) assessing key ecological drivers of population change; and (3) projecting future abundance and distribution of focal species, including mammals, birds, fish, and aquatic invertebrates that use the landscapes of the Arctic in different ways and likely will express differently the consequences of changes to the associated ecosystems. USGS Alaska Science Center (ASC), monitors bird populations in several sites and these are the results of those studies.

| 研究區域描述 | This study is being conducted on a variety of Alaska's ecosystems: 1) Chipp on the ACP between the Brooks Range and the Arctic Ocean, north of the Arctic Circle (~70° 32' N, -155° 21' W). This area is part of the NPR-A, where oil and gas development is expected to increase, and is owned and managed by the BLM. The region consists of low tundra, including sedge, moss, dwarf-shrub wetlands (W2) and tussock-sedge, dwarf-shrub, moist tundra (G4) ecosystems described in the Circumpolar Arctic Vegetation Map (Walker et al. 2005). There is an extensive system of fish-bearing lakes and several major drainage rivers. More specifically, our research is confined to two, 7 kilometer-squared study plots, approximately 35 km apart, along the Chipp River, 100 km (60 miles) southeast of the community of Barrow. Each plot exhibits different ecological and climatic characteristics; Chipp North (N 70.686, W-155.304) -- this dataset -- is closer to the coast and lower lying, while the Chipp South (N 70.395, W -155.407) is more inland, having rolling terrain features. 2) Several areas of Alaska's Seward Peninsula, including beyond the international date line. 3) Alaska's North Slope along the Colville River Delta. |

Different sampling methods were used. For Loons- Observers conducted complete nest searches by walking the shoreline of all lakes in both study plots. Nest locations were marked with a hand-held GPS unit and revisited to monitor nest fate at weekly intervals. Some lakes extending outside the plot boundary were also searched as time and resources allowed, thereby increasing sample sizes.
