Alaska has diverse boreal ecosystems across heterogeneous landscapes driven by a wide range of biological and geomorphic processes associated with disturbance and successional patterns under a changing climate.
This is the fourth in a series of periodic monitoring reports on status and trends of forests used by northern spotted owls (Strix occidentalis caurina; NSO) for nesting, roosting, and dispersal on federally administered lands within the Northwest Forest Plan (NWFP) area (NSO range in the U
Urban parks provide many ecosystem services, and conserving biodiversity is one of the most important among them. Keeping track of biodiversity indices and their evolution over time is a useful procedure for preserving biodiversity within urban habitats.
Ecological disturbance is a key agent shaping the spatial and temporal landscape of food availability. In forests of western North America, disturbance from fire can lead to resource pulses of deadwood-associated arthropods that provide important prey for woodpeckers.
The Starkey Project is a unique program that has combined long-term research with multi-disciplinary, multi-partner involvement. The research was, and still is, designed to answer management questions.
Determining the demographic impacts of wildlife disease is complex because extrinsic and intrinsic drivers of survival, reproduction, body condition, and other factors that may interact with disease vary widely.
In ecogeomorphic systems, such as beach-dune habitats, complex couplings exist between geomorphology and ecology. Abiotic conditions influence vegetation growth and distribution while vegetation imposes a geomorphic feedback, impacting topography.
