A study was done on the zoogeography of species of oceanic
shrimp in the North Pacific from 22°N to 56°N and from 124°W to
145°E, using samples of shrimp collected from 1954 to 1969. These
collections were made during the following cruises: John R. Manning
Cruise 22, and the Hugh...
Site 35JA42 represents the first protohistoric village
complex excavated in Southwest Oregon. Analyses of animal
bones recovered from the site offer the first significant
insights into human subsistence behaviors in this region.
Although the faunal assemblage is extremely fragmented,
detailed zooarchaeological analysis indicates that deer were
the primary meat resource...
There are record numbers of immigrants in the U.S., with no indication of declining in the future. Social debates surrounding issues such as immigration are fragile. It is critical that research and knowledge put out to the public and used by policy makers to create or reform immigration legislation must...

Local property-owning residents maintain high levels of interest
and awareness regarding a neighboring natural resource complex.
Factors, however, such as proximity, personal interests, use patterns
and economic considerations cause local inhabitants to have an
inaccurate perception of the natural resource complex. The nature
of local resident perception can be analyzed...
Mantel-based tests have been the primary analytical methods for understanding how landscape features influence observed spatial genetic structure. Simulation studies examining Mantel-based approaches have highlighted major challenges associated with the use of such tests and fueled debate on when the Mantel test is appropriate for landscape genetics studies. We aim...

The Horseshoe Gulch area includes 16 square miles in the
Eastern Paleozoic Belt of the Klamath Mountains geologic province
north of Callahan, California. Fossiliferous Late Ordovician and
Silurian limestones and unfossiliferous greywackes, arkoses, shales,
mudstones, schists, and phyllites, and other terrigenous clastic
rocks are exposed in a broad fault zone...

Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...
Human alterations of landscapes take many forms, one of which is anthropogenic pollution. Mercury (Hg) is a complex contaminant because its uptake into the food web is not driven entirely by loading to the system; methylation is necessary to make Hg bioavailable and toxic to fish and wildlife. Because methylation...
