  Citation × Citation Citation Abstract Copy Title: Willamette Valley prairie restoration : the Native Seed Network and Sidalcea Author: Lambert, Joshua K. My internship was conducted with the Native Seed Network program within the Institute for Applied Ecology, a non-profit organization located in Corvallis, whose focus is education, applied research and active restoration and of native ecosystems. My internship goals were to increase my experience in applied restoration ecology and conservation biology with the emphasis on native plant communities in particular the endangered prairie communities of the Willamette Valley. These goals were met through my tenure with the Native Seed Network’s native seed collection and increase program during the 2007 field season. This work provided me strong experience with a process necessary for genetically conservative restoration and provided the NSN with a willing intern to complete their goals for 2007. Additional work I accomplished included a morphometric analysis of the native Willamette Valley prairie forb Sidalcea campestris which served as one constituent towards resolving the general ambiguity of this focal species for prairie restoration. Included in this analysis is a presentation and my interpretation of an initial molecular phylogenetic analysis on a selection of S. campestris accessions by Liston and deFeniks (unpublished) that may aid in the future resolution of S. campestris and other congeners in the Willamette Valley. The purpose of the morphological research was not mastery of population genetics or statistics but an exercise in concentration and achievement towards a more integrated and advanced application of taxonomic work oriented towards preserving biological diversity. This entire report completes the written requirement for the Professional Science Masters degree in Applied Systematic through the Botany and Plant Pathology Department at Oregon State University.

  Citation × Citation Citation Abstract Copy Title: Spatial and vertical distribution of the invasive European green crab in a temperate estuarine system Author: Weldon, Taylor, Lundeberg, Christopher The European green crab, Carcinus maenas, is a generalist predator that has established invasive populations throughout the world, including the west coast of North America. In Oregon, strong cohorts of green crabs recruit only during major El Niño events. The goals of this study are to: 1) compare the abundance and growth of the recent 2014-2015 El Niño cohort to that of the strong 1997-1998 El Niño in Yaquina Bay, Oregon, and 2) explore the spatial and vertical distribution of C. maenas and how it relates to that of the native red rock crab, Cancer productus. An abundance and size distribution similar to the 1997-98 cohort was observed, indicating favorable current patterns and growing conditions brought on by the strong El Niño. We did not find a correlation between the spatial distribution of C. productus and C. maenas, however it is possible that the distribution is related to the dynamics of the bay or microhabitat preference. Our data suggests a negative correlation in the vertical tidal distribution of the two species, supporting the hypothesis that C. productus sets the vertical lower limit of C. maenas. Observations of the interactions of the two species in the same trap support this hypothesis. Future studies should follow the 2015 year class and its effects on the local ecosystems. These data could prove a valuable tool in making predictions on the indirect effects of El Niño or the establishment of a self-sustaining C. maenas population in Yaquina Bay.
