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...
Ocean Acidification (OA) has emerged as a major threat to marine ecosystems, particularly regarding calcifying organisms. A growing body of literature describing laboratory investigations into pH stress indicates broadly deleterious effects for calcifiers, but responses vary greatly across taxa and can be influenced by variations in other environmental characteristics. Scaling...
Ten herbicides (atrazine, azafenidin, chlorsulfuron, clopyralid, hexazinone, imazapic, imazapyr, metsulfuron, pendimethalin, and sulfometuron) were evaluated for phytotoxicity in first-year seedlings of eight conifer species (Douglas-fir, grand fir, noble fir, redwood, Sitka spruce, western hemlock, western red cedar, and western white pine). Six of these herbicides (atrazine, clopyralid, hexazinone, imazapyr, metsulfuron,...
Concern over the increasing proportion of juvenile wood grown in second growth plantations has led to a large amount of research on the effects of common silvicultural practices on wood quality. Lacking is research on the effect of timing and
duration of vegetation control on wood quality near the pith...
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...

Many online learning environments use prerecorded video lectures as a primary mode for disseminating learning content. Despite the commonality of this lecture-based video format, it is not clear to what degree video length and the incorporation of active learning elements influence learner success. We investigated the efficacy of segmenting pre-recorded...
