New USGS Analysis of Wind Turbine Upgrades Shows No Impact on Wildlife Mortality

CORVALLIS, ORE. – Reduction in wildlife mortality rates is sometimes cited as a potential benefit to the replacement of older, smaller turbines by larger, next generation turbines. In contrast, others have expressed concern that newer, larger turbines may actually increase bird and bat deaths.

Fish Habitat Use and Food Web Structure Following Pond-and-Plug Meadow Restoration

The ‘‘pond-and-plug’’ meadow-restoration technique, in which ponds are formed by excavating the floodplain and plugging incised channels with the excavated material, is commonly used in montane meadows in the Sierra Nevada.

Weather and Distance to Fire Refugia Limit Landscape-Level Occurrence of Fungal Disease in an Exotic Annual Grass

Exotic species invasion may occur because of the lack of natural enemies, such as pathogens, in introduced ranges.

Detecting Shrub Recovery in Sagebrush Steppe: Comparing Landsat-Derived Maps with Field Data on Historical Wildfires

Sagebrush can be scarce after fires in a semiarid ecosystem and their paucity over vast burn areas creates challenges for detection by remote sensing.

Evaluating Performance of the Ecosystem Demography Model in Simulating Dryland GPP

Dynamic global vegetation models can reveal much about carbon cycling in different ecosystems, yet the performance of these models in drylands is complicated partly by the heterogeneity of the vegetation and hydrometeorological conditions.

Stream Restoration is Influenced by Details of Engineered Habitats at a Headwater Mine Site

A lack of information regarding which ecological factors influence restoration success or failure has hindered scientifically based restoration decision-making.

Evaluating Coexistence of Fish Species with Coastal Cutthroat Trout

Many stream studies in the Pacific Northwest have focused solely on coastal cutthroat trout, the most prevalent species, though it is well-known that interactions within the total species assemblage can be important.

Understanding the Effect of Fire on Vegetation Composition and GPP in a Semi-Arid Shrubland Ecosystem Using the Ecosystem Demography (EDv2.2) Model

There is a gap in understanding the impacts of wildfire on vegetation at broad spatial and temporal scales, highlighting the need for accurate global dynamic vegetation models.

Climate-Mediated Changes to Linked Terrestrial and Marine Ecosystems across the Northeast Pacific Coastal Temperate Rainforest Margin

Coastal margins at the interface between land and ocean are important areas of materials flux – such as carbon and nutrients transported in river discharge – that link terrestrial and marine ecosystems. Climate is central to these fluxes, which in turn influence nearshore ocean chemistry and food web dynamics.
