Spatial And Temporal Patterns Of Amphibian Chytrid Fungus Batrachochytrium Dendrobatidis Occupancy In Amphibian Habitats, Tara Chestnut Jan 2013

Spatial And Temporal Patterns Of Amphibian Chytrid Fungus Batrachochytrium Dendrobatidis Occupancy In Amphibian Habitats, Tara Chestnut

Environmental Science and Management Professional Master's Project Reports

Chytrid fungi are the most ancestral of the fungi and are global in distribution. There are over 1200 species of Chytridiomycota described from freshwater, marine and terrestrial systems in temperate, tropical and tundra environments. Chytridiales are characterized by a range of morphologies and share the flask- or pot-like shape of the zoosporangia, within which motile zoospores develop. Chytrids function primarily as plant saprobes and parasites, but some also parasitize animals. Chytrids are observed in conjunction with the decline of freshwater and marine algal blooms, they decompose excess pollen, and comprise the fungal flora in gut of herbivores. Some chytrids also …


Understanding The Drivers Of Forest, Residential, And Agricultural Land Values In Yamhill County Using Hedonic Models, Emily D. Dietrich Jan 2013

Understanding The Drivers Of Forest, Residential, And Agricultural Land Values In Yamhill County Using Hedonic Models, Emily D. Dietrich

Environmental Science and Management Professional Master's Project Reports

Hedonic modeling is commonly used in land and property value estimations in an attempt to identify the impact that various attributes have on the market value of that property. The purpose of this study is to examine the factors contributing to land value of agricultural, forest, and residential properties in Yamhill County, as part of the Spatial Ecosystem Services Analysis, Modeling, and Evaluation (SESAME, http://www.pdx.edu/ecosystem-services/) project. This paper discusses the process and preliminary results of the development of hedonic models that will be utilized for predicting land value changes under future land conversion scenarios. Applying the models to future scenarios …
