An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
An Ecological Comparison Between Resource Subsidies: Pacific Lamprey (Entosphenus Tridentatus) And Pacific Salmon (Oncorhynchus Spp.), Jocelyn Wensloff
All Master's Theses
Historically, oligotrophic Pacific Northwest (PNW) streams received annual returns of spawning anadromous fish that provided resource subsidies in the form of marine-derived nutrients (MDN), thus driving stream food web productivity. To date, many studies in the PNW have focused on Pacific salmon (Oncorhynchus spp.) as a resource subsidy, overlooking other anadromous fish species such as Pacific lamprey (Entosphenus tridentatus). Both Pacific salmon and Pacific lamprey are culturally important to PNW tribes for ceremonial, medicinal, and subsistence purposes, and have been since time immemorial. Unfortunately, both salmon and lamprey populations are in decline. Historically, lamprey have been disregarded …
A Regional Synthesis Of Post-Glacial Fire History In The Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis, Brynn Harrison
A Regional Synthesis Of Post-Glacial Fire History In The Eastern Cascades, Washington, Using Macroscopic Charcoal Analysis, Brynn Harrison
All Master's Theses
The recent rise in severe wildfires in the Pacific Northwest (PNW) has created a heightened sense of urgency and reignited public interest in wildfire risk. In order to put this rise into a broader spatial and temporal context, a more in-depth look at fire histories from frequently burned areas in the eastern Cascades is needed. The first major objective of this study was to determine if CharAnalysis, a statistical program developed to reconstruct fire history from macroscopic charcoal-based records, is appropriate for use with charcoal records from the eastern Cascades of Washington. The second major objective was to develop a …
