The boreal forest is the northern-most woodland biome, whose natural history is rooted in the influence of low temperature and high-latitude. Alaska's boreal forest is now warming as rapidly as the rest of Earth, providing an unprecedented look at ho

We investigated spatial variability in the community structure of stream macroinvertebrates at six reaches within Caribou-Poker Creeks Research Watershed in the Alaskan taiga forest. Stream reaches differed most notably in river continuum position (s

We examined the spatial distributions of Alaskan freshwater fishes using 2 frameworks, ecoregions and hydroregions (catchments). Ecoregions are defined by climate, terrain, vegetation, and soils; their utility in explaining distributions of aquatic o

Understanding interactions between permanently frozen soils and stream chemistry is important in predicting the effects of management, natural disturbance and changing perma- frost distribution on stream ecosystems and nutrient budgets in subarctic w

Alaska's great size is mirrored by the large number and diversity of its freshwater ecosystems. This volume reviews and synthesizes research on a variety of Alaskan freshwaters including lakes, rivers and wetlands. The vast range of Alaskan habitats

E cologists usually study systems at spatial and temporal scales (e.g., from centimeters to meters and from minutes to days) that are within easy range of human perception. Critical ecological processes, however, occur over a range of spatial and tem

SUMMARY 1. Forest stream food webs depend largely on input of dead riparian zone leaves for their energy, which is converted into living biomass by microbes, macroinvertebrates and fish. 2. Temperature has been invoked as important in controlling bre
