Studying the ancient parasitic cnidarian, Sphaerospora elegans, leads to better understanding of oligochaete diversity and myxozoan discovery

Creator:: Lehrburger, David J.
Abstract:: Myxozoans are microscopic parasites, related to corals and jellyfish. Most Myxozoa probably have two-host lifecycles that require a vertebrate (typically fish) and invertebrate (annelid or bryozoan). However no life cycle is known from the Sphaerospora lineage. I hypothesized that the life cycle of Sphaerospora elegans, a myxozoan parasite of three-spined...

Fall Creek Reservoir Water Quality Dataset

Creator:: Hamilton, Stephen K., Murphy, Christina A., Johnson, Sherri L., and Pollock, Amanda M.M.
Abstract:: Water chemistry measurements taken at or downstream of Fall Creek Reservoir, OR (43.9459714, -122.755765). Fall Creek is a tributary of the Middle Fork Willamette River, located approximately 20 miles SE of Eugene, Oregon, USA. Water chemistry measurements included water samples collected from the reservoir outflow (during autumn drawdown) and within...

Management controls and pressure groups: the mediation of overflows

Creator:: Jollands, Stephen, Akroyd, Chris, and Sawabe, Norio
Abstract:: Purpose Organisations produce effects that go beyond the economic framing within which they operate, referred to as overflows in this paper. When an organisation comes under pressure to address these overflows they must decide how to respond. Previous research has placed social and environmental reporting as an important tool organisations...

Error Propagation in Sap Flow Measurements Using the Heat Ratio Method

Creator:: Miller, Jackson T.
Abstract:: Accurate estimation of the amount of water used by trees is important for a variety of agricultural applications. There are several current methodologies for measuring sap flow and water use in trees, however the heat ratio method has been identified as the ideal due to its ability to measure low...

Development of Computational, Visualization, and Molecular Tools for Fungal and Oomycete Community Ecology

Creator:: Foster, Zachary Stephen Longiaru
Abstract:: Oomycetes are an important group of organisms with a variety of ecological roles similar to fungi. Although many are well-studied plant pathogens known for their devastating effects on agricultural systems, most are little-studied saprobes and parasites of plants and animals in nearly every ecosystem on earth. The advent of affordable...

An auction mechanism for the optimal provision of ecosystem services under climate change

Creator:: Lewis, David J. and Polasky, Stephen
Abstract:: The provision of many ecosystem services depends on the spatial pattern of land use across multiple landowners. Even holding land use constant, ecosystem service provision may change through time due to climate change. This paper develops an auction mechanism that implements an optimal solution for providing ecosystem services through time...

The Dynamics of Random Pulse-Coupled Oscillator Networks

Creator:: Kadhim, Kyra L.
Abstract:: The pulse-coupled oscillator model is widely used to simulate the dynamics of neural systems. For networks with particular internal (Mirollo-Strogatz) dynamics, I will define three broad patterns of collective behaviors found in literature in terms of inter-spike interval (ISI) statistics. These patterns are i) temporally-regular, characterized by all oscillators in...

Hacking RFID Tags to Produce Economical Soil Moisture Sensors

Creator:: Stoddard, Brett S.
Abstract:: Currently available soil moisture sensors have intrinsic limitations that limit their adoption by industry. Depending on the technology, these limitations may include high costs, battery requirements, precice manual installation, high cost, and/or constrictive legislation that regulates their use. A passive soil moisture sensing system based around RFID technology would allay...

Mental Health in Eastern Europe during the COVID-19 Pandemic: A Systematic Review and Meta-Analysis of Depression and Anxiety

Creator:: Miller, Saylor O.
Abstract:: Objective: To perform a systematic review and meta-analysis on the prevalence rate of mental health disorders including anxiety, depression, and insomnia during the COVID-19 pandemic in Eastern Europe in the general population, as well as within select sub-populations (i.e., students, general healthcare workers, and frontline workers). Data sources: Articles in PubMed,...

River Microbiome Composition Reflects Macroscale Climatic and Geomorphic Differences in Headwater Streams

Creator:: URycki, Dawn R., Good, Stephen P., Crump, Byron C., Chadwick, Jessica, and Jones, Gerrad D.
Abstract:: Maintaining the quality and quantity of water resources in light of complex changes in climate, human land use, and ecosystem composition requires detailed understanding of ecohydrologic function within catchments, yet monitoring relevant upstream characteristics can be challenging. In this study, we investigate how variability in riverine microbial communities can be...
