Modeling vertebrate diversity in Oregon using satellite imagery

Creator:

Cablk, Mary E.

Abstract:

Vertebrate diversity was modeled for the state of Oregon using a parametric approach to regression tree analysis. This exploratory data analysis effectively modeled the non-linear relationships between vertebrate richness and phenology, terrain, and climate. Phenology was derived from time-series NOAA-AVHRR satellite imagery for the year 1992 using two methods: principal...

Modeling water uptake on coniferous forest Oregon watershed 10 synthesis

Creator:

Waring, Richard H., Running, S. W., Holbo, Harold Richard, Kline, J. R., U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

In the Coniferous Forest Biome, many of the understory as well as dominant plants are evergreen and thus water uptake is a year around process. The flow of water from the soil through plants to the atmosphere affects the entire forest ecosystem. As water is evaporated, it absorbs heat and...
