Many studies have looked at human settlements around individual volcanoes for
volcanic risk analyses, but few have done a comparative study to identify possible global
patterns. With the use of Landsat ETM+ data, this study identifies and compares urban
proximity to the Decade Volcanoes to identify volcanic settlement patterns. These...
During boreal summer and fall, there is a strong southerly boundary layer flow across the equator into the east Pacific intertropical convergence zone (ITCZ). The modulation of this flow on synoptic to seasonal time scales is studied using an index of meridional pressure difference between the equator and the ITCZ...
Describes chipmunks and their habits. Explains what type of habitat they need and how you can provide habitat in your yard. Includes sources of additional information and “fun facts.”
This prioritization is designed to provide strategic focus for tidal wetland conservation and restoration actions undertaken in partnership with willing landowners. The stufy highligts land areas in the Umpqua River Estuary where tidal wetland restoration or conservation action may offer the biggest ecological "bang for the buck" - that is,...

Oregon Natural Heritage Information Center Report.
Sphagnum fens on the coast of Oregon are unique globally and contain a variety of rare plants and animals found nowhere else in the landscape. Evidence indicates that in the absence of disturbance, many open fens have converted to tall shrub and forest stands...
This document provides information on the palatability of plants on Mongolian rangelands including native and introduced vascular plants by major seasonal periods: winter (January - March), spring (April- June), summer (July - September), and autumn (October - December). In addition to this, some species of valuable lichen species are also...
Skunks, opossum, raccoons, coyotes, deer, and elk often are lumped into the unofficial taxonomic family “nuisance wildlife.” Actually, any kind of wildlife can fit this description, from rattlesnakes to woodpeckers, and even beavers. Most often, however, problems caused by nuisance wildlife can be managed or avoided altogether.
The ponderosa pine ecosystem of the West have changed dramatically since Euro-American settlement 140 years ago due to past land uses and the curtailment of natural fire. Today, ponderosa pine forests contain over abundance of fuel, and stand densities have increased from a grange of 49-124 trees per ha (20-50...
