Population Genetics of American Pika (Ochotona princeps) : Investigating Gene Flow and Genetic Diversity Across Multiple, Complex Landscapes

Creator:: Castillo, Jessica A.
Abstract:: American pikas (Ochotona princeps) are considered an indicator species of climate change. Adaptations for cold climates and active winters make pikas particularly sensitive to increasing temperatures. This, combined with evidence that multiple historically occupied populations have been extirpated within the past century, contributed to American pikas becoming a focal species...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...
