1. Despite their importance in determining the rate of both energy gain and expenditure, how
the fine-scale kinematics of foraging are modified in response to changes in prey abundance
and distribution remain poorly understood in many animal ecosystems.

A major focus in macroecology is to understand the mechanisms that drive differences in habitat, morphology, and behavior in closely related species (Brown 1995). Within this paradigm, energy use and prey acquisition play a fundamental role in affecting behavior, especially with respect to foraging patterns and predator‐prey interactions. Because resources...
Seeding is a vital tool to facilitate recovery of degraded ecosystems, but low seedling recruitment rates limit the utility of this practice in a range of ecosystems across the globe. Plant functional traits impact individual fitness through effects on growth, reproduction and survival. Consequently, seed and seedling trait variation among...

Predicting the average affect of a piece of music is a task which has been of recent interest in the field of music information retrieval. We investigate the use of sentiment analysis on online social media conversations to predict a song’s valence and arousal. Using four music emotion datasets -...
Marine environments provide services for ecosystems and humans, but face many threats, including sea star wasting disease (SSWD) and ocean acidification (OA). Biological research on these threats is abundant, but there has been limited research examining the human dimensions of these threats. This thesis contains two standalone articles that explore...
Air-breathing marine animals face a complex set of physical challenges associated with diving that affect the decisions of how to optimize feeding. Baleen whales (Mysticeti) have evolved bulk-filter feeding mechanisms to efficiently feed on dense prey patches. Baleen whales are central place foragers where oxygen at the surface represents the...
Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, timber, and aesthetics. A retrospective approach was taken in this study in order to understand and compare the structure, pattern, and history of an...
Wildland firefighters encounter many situations during forest fires that require
them to rely on their knowledge, experience, and fitness level for survival While energy
expenditure of wildland firefighters on the fire line has been well established, relatively
little is known about the physical fitness level of wildland firefighters when they...
