Background:
Phylogeographic studies of aquatic insects provide valuable insights into mechanisms that shape the genetic structure of communities, yet studies that include broad geographic areas are uncommon for this group. We conducted a broad scale phylogeographic analysis of the least salmonfly Pteronarcella badia (Plecoptera) across western North America. We tested...

In response to concerns about excessive stand densities and high-severity wildfires, land
managers in the western United States are carrying out extensive programs of fuel reduction
thinning. How will these sudden reductions in canopy cover and associated changes in
habitat affect native and exotic herbaceous vegetation and canopy species regeneration?...

AN ABSTRACT OF THE THESIS OF
KeithA. Perchemlides for the
Early and later successional stages of the assemblage of turf algae and sessile
animals of a Macrocystis kelp forest were studied off San Nicolas Island, California
from 1980 through 1981, and 1983 through 1984. Kelps were manipulated to
determine if differences in illumination could account for dominance by turf algae...
This study describes the composition of forest landscapes surrounding
northern spotted owl (Strix occidentalis caurina) nests in the central Cascade
Mountains of Oregon. I compared forest composition around 126 owl nests in 70 pair
territories with forest composition around 119 points drawn randomly from all
terrestrial cover-types, and around 104...
