Revegetation in the 1914-1915 devastated area of Lassen Volcanic National Park

Creator:: Bailey, Warren Hutchinson, 1914-
Abstract:: At the time of the eruptions of Lassen Peak in 1914-1915, an area of vegetation along the east slope of the mountain approximately 1 1/4 miles wide and four miles long was destroyed. Except for a few surviving trees, all vegetation was destroyed. A study of the revegetation of this...

On the Role of Spatial Clustering Algorithms in Building Species Distribution Models from Community Science Data

Creator:: Roth, Mark
Abstract:: This paper discusses opportunities for developments in spatial clustering methods to help leverage broad scale community science data for building species distribution models (SDMs). SDMs are critical tools that inform the science and policy needed to mitigate the impacts of climate change on biodiversity. Community science data span spatial and...

Machine Learning Techniques to Model Species Interactions and Distributions Under Imperfect Detection

Creator:: Seo, Eugene
Abstract:: Ecological domains seeking to understand the environment and the behavior of species have received little attention in machine learning (ML), despite the fact that environmental changes have a significant impact on humans as well as ecosystems. Some ecological problems can be formulated similarly to other common ML applications, but there...

Species Distribution Modeling of Citizen Science Data as A Classification Problem with Class-Conditional Label Noise

Creator:: He, Liqiang
Abstract:: Species distribution models (SDM), which quantify the correlation between the distribution of a species and environmental factors, are increasingly used to map and monitor animal and plant distributions in the context of awareness of environmental change and its ecological consequence. For perfect data, this is a straightforward classification problem from...

The Nature of Sulfate Saturation in Oxidized Arc Magmas: Implications for Magmatic Sulfur Budgets

Creator:: Hutchinson, Michael C.
Abstract:: This dissertation is concerned with the behavior of sulfur in intermediate-silicic arc magmas associated with subduction at convergent margins. In particular it focusses on oxidized, sulfur-rich magmas, the conditions at which they might reach sulfate saturation, and implications of sulfate saturation. It is divided into an investigation of natural samples...

Geomorphic influences on habitat formation, distribution, and development and the classification of upland coastal Oregon streams

Creator:: Hurley, Michael D.
Abstract:: A framework is presented for a more causal explanation and ordering of stream characteristics than traditional means have used. Patterns of stream habitat distribution are related to particular characteristics of the geomorphology of watersheds. Variability in stream characteristics can be explained by the spatial distribution of properties of the watershed...

Treatment options for controlling Brachypodium sylvaticum and impacts on native vegetation

Creator:: Fjeran, Taylor K.
Abstract:: Invasive vegetation control studies traditionally aim to control existing populations as well as limit future spread of the species. However, little additional attention has been dedicated to aiding native communities to recover and reestablish. One prominent example of a studied invasive is Brachypodium sylvaticum (Huds.) P. Beauv. (false brome), a...

Towards autonomous irrigation : comparison of two moisture sensing technologies, irrigation distribution analysis, and wireless network performance at an ornamental container nursery

Creator:: Bailey, Daniel R.
Abstract:: As ornamental container nurseries face diminishing water allocations, many are looking to automated irrigation solutions to increase their water application efficiency. This thesis presents the findings of a study conducted at a commercial container nursery to determine 1) whether a capacitance or load cell sensor was better suited for monitoring...
