Subsistence Harvest Diversity in Alaskan Food Sharing Networks

Creator:: Scaggs, Shane A.
Abstract:: Two striking characteristics of human beings are the diversity of resources that we use to sustain our lives and the extent to which we engage in coordinated, collective efforts to obtain and consume these resources. Together, these two characteristics are the foundation of human subsistence patterns. In many remote Alaskan...

An Agent-Based Simulation for Emergency Warning Dissemination in a Multiplex Social Network

Creator:: Koll, Charles D.
Abstract:: The variety of natural disasters provide different sets of characteristics and properties with unique challenges. One significant difference between hazard types is prewarning lead time, the amount of time individuals have from a potential warning to the disaster occurring. Rapid onset disasters may not provide an official warning about a...

Mental Models of Mere Mortals with Explanations of Reinforcement Learning

Creator:: Anderson, Andrew A.
Abstract:: How should reinforcement learning (RL) agents explain themselves to humans not trained in AI? To gain insights into this question, we conducted a 124 participant, four-treatment experiment to compare participants’ mental models of an RL agent in the context of a simple Real-Time Strategy (RTS) game. The four treatments isolated...

Novel methods for crop load management of pear cultivars in the Pacific Northwest

Creator:: Arrington, Matthew A.
Abstract:: Novel approaches to crop load management of pear orchards in the Pacific Northwest (PNW) are necessary, but will need to vary according to the unique vegetative and reproductive growth habits of the cultivar. 'D'Anjou' is vigorous and non-precocious; thus, strategies to limit vigor and induce early fruiting are required. In...

Does Fatigue Influence the Assessment of Critical Speed when Multiple Test Trials are Conducted in a Single Session

Creator:: Jones, Cameron
Abstract:: The Critical Power - W’ model has many advantages compared to the traditional VO2max test, including tracking fitness changes over time in well trained athletes, predicting performances due to its discrete aerobic and high intensity tolerance variables, and prescribing exercise intensities with increased accuracy. However, a major disadvantage of this...

Exploring Alternative Approaches for Native Plant Production and Ecological Restoration in the Pacific Northwest

Creator:: Placido, Wilman M.
Abstract:: Global recognition of the need for ecosystem restoration and revegetation following natural and anthropogenic disturbances has been growing in recent years. Successful programs often depend on the use of nursery-grown seedlings and appropriate mitigation of limiting factors on outplanting sites. Nursery production of high-quality native plants for restoration can be...

Use of Landscape Characteristics to Quantify Hybridization Risk Between Native and Introduced Salmonids

Creator:: Manning, Michael A.
Abstract:: The introduction of non-native species can negatively impact native species through reduced genetic fitness resulting from hybridization. The lack of spatiotemporal data of hybrids occurrences makes assessing hybridization risk difficult. Here, I developed a spatially-explicit GIS Hybridization Risk Model (HRM) between native ESA-listed Bull Trout and introduced Brook Trout by...

Tackifier Type and Concentration have Varying Impacts on Growth of Dryland Mosses

Creator:: Blankenship, Wyatt D.
Abstract:: There is growing interest in using biocrusts (assemblages of cyanobacteria, lichens, mosses, and other taxa in various proportions covering the upper few millimeters of the soil surface) to assist in restoring ecosystem function and native plant communities in dryland ecosystems. Biocrusts can be transplanted and established using jute or thatch,...

Determination of Trade-offs between Wetland Ecosystem Services in an Agricultural Landscape

Creator:: Garrison, Stacey L.
Abstract:: Wetland restoration mitigates effects of agricultural development on water quality, flooding, and habitat loss. Multi-objective optimization for wetland locations and sizes has not included objective functions for water quality, hydrology, and habitat in unison, limiting analysis of trade-offs among these ecosystem services. This study establishes two methods to improve the...

Prespawning Mortality of Fall Creek Willamette Chinook Salmon (Oncorhynchus tshawytscha): Evaluation of the Effects of a New Trap at the Adult Fish Collection Facility

Creator:: Carey, Katherine
Abstract:: Annual rates of prespawn mortality (PSM) in adult Chinook salmon (Oncorhynchus tshawytscha) trapped and transported upstream of dams in the Willamette River basin are high (often >40%) and could limit the ability to restore natural populations of spring Chinook salmon if not reduced. Improvements at the U.S. Army Corps of...
