The rapid accumulation of polyethylene terephthalate (PET) plastic waste caused by disposable plastic water bottle use is a worldwide problem that will continue to affect our environment, economy and society unless new methods of reduction and degradation are explored. The large amounts of energy and resources that are required during...
Dendritic ecological networks (DENs) are a unique form of ecological networks that exhibit a dendritic network topology (e.g. stream and cave networks or plant architecture). DENs have a dual spatial representation; as points within the network and as points in geographical space. Consequently, some analytical methods used to quantify relationships...
The objectives of this study were: a) to obtain and evaluate
equipment for bio-acoustical analysis for this work and for future
work in the analysis of insect sounds, b) to study the acoustical and
sexual behavior of Acheta domesticus L., and c) to determine methods
for analyzing the changes effected...
This dissertation describes the application and development of molecular tools that have great potential for use in studying variation in strawberry germplasm. The first study evaluated 91 microsatellite (simple sequence repeat, SSR) markers for transferability in 22 Fragaria species and their utility in fingerprinting octoploid strawberries. Out of the transferable...
Geographic patterns of genetic variation in wild species reflect the interplay of ecological and evolutionary processes. We assessed genetic variation in three genomes across four North American diploid strawberry taxa, with special emphasis on the gynodioecious Fragaria vesca subsp. bracteata (A.Heller) Staudt. Specifically, we sequenced one chloroplast (rpoC2) and two...

The Murderers Creek Area, within the Aldrich Mountain province of
northeast Oregon, originated in an arc-trench gap during Permian-early
Triassic time. The area represents a small portion of a forearc
depositional basin and tectonic highland which borders the basin along
its seaward margin. The trench associated with an east dipping...

Biodiversity loss is of global concern, and is due in part to deforestation and high consumer demand for wood and wood products. The neotropical tree species Cedrela odorata (“Spanish cedar” or “cedro”) is economically valuable for its wood and faces threats of overexploitation. Due to strong similarities in wood features...
