Forest fires contribute a significant amount of CO₂ to the atmosphere each year, and CO₂ emissions from fires are likely to increase under projected conditions of global climate change. In addition to volatilizing aboveground biomass and litter layers, forest fires have a profound effect on belowground carbon (C) pools and...
The quantity and characteristics of coarse woody debris (CWD) were examined
in four distinct pine ecosystems of north-western (NW) Spain, NW Russia and
the NW USA. The average CWD volume and biomass ranged from 3.76 m³ ha⁻¹,
1.55 Mg ha⁻¹ in pine plantations in NW Spain to 24.86 m3 ha⁻¹,...
This study consisted of two research projects in the Wyoming big sagebrush
(Artemisia tridentata ssp. wyomingensis (Beetle & A. Young) S.L. Welsh) alliance,
the most extensive of the big sagebrush complex in the Intermountain West. In the
first project, we intensively sampled 107 relatively undisturbed, late seral Wyoming
big sagebrush...
Coral reefs are in decline worldwide, and land-derived sources of pollution, including sewage, are a major force driving that deterioration. This review presents evidence that sewage discharge occurs in waters surrounding at least 104 of 112 reef geographies. Studies often refer to sewage as a single stressor. However, we show...
This report describes results of baseline monitoring at the Ni-les’tun tidal wetland restoration site, Bandon National Wildlife Refuge, Coquille River estuary of Oregon. Baseline monitoring provides a basis for comparison to post-restoration conditions, allowing future determination of project effectiveness. The report focuses on 2010-2011 baseline data, but it also includes...
Despite relatively mild weather, black bears (Ursus americanus)
in southwestern Washington entered dens and remained for an average
of 126 days. Bears entered their dens during a 5-week period which
began on 21 October. A significant difference (P < 0.05) was found
among the average dates of den entrance of...
In ecological restoration, species that are sown to increase the native plant
diversity range in establishment ability. Some species readily establish, while others
rarely do. This study set out to investigate some of the potential processes influencing
species establishment, as well as the traits that are associated with the success...
Vegetation provides food for many insects, and many insects serve as food for bats. We investigated the linkages among these three trophic levels in riparian areas throughout the Oregon Coast Range by examining the influence of vegetation cover, composition, and structure on the activity of nocturnal insects and bats, the...
