Hobby activities can be viewed through the lens of informal, free-choice learning. A wide range of hobbies combine fun and learning-intensive practices, and can contribute to scientific literacy. Hobby learning involves clear goal orientation, persistence and effort, and often results in more richly and strongly connected knowledge; traits highly valued...
Japanese, giant, and the hybrid Bohemian
knotweeds (Fallopia japonica, F. sachalinensis and
F. x bohemica) have invaded the western USA and
Canada, as well as other regions of the world. The
distribution of these taxa in western North America,
and their mode of invasion, is relatively unresolved.
Using amplified fragment...

This book provides an illustrated guide to the identification and management of fungi, insects, and abiotic conditions that cause problems in Northwest bareroot conifer nurseries. A key to nursery pests offers initial guidance in identification. Separate chapters address individual pests with details on recognition, damage cycle, and management practices to...
Landscape fire succession models (LFSMs) predict spatially–explicit interactions between vegetation
succession and disturbance, but these models have yet to fully integrate ungulate herbivory as a driver of
their processes. We modified a complex LFSM, FireBGCv2, to include a multi-species herbivory module,
GrazeBGC. The system is novel in that it explicitly...
For widely distributed species at risk, such as Pacific salmon (Oncorhynchus spp.), habitat monitoring is both essential and challenging. Only recently have widespread monitoring programs been implemented for salmon habitat in the Pacific Northwest. Remote sensing data, such as Landsat images, are therefore a useful way to evaluate trends prior...
BACKGROUND: Low levels of moderate-to-vigorous physical activity are associated with adverse health consequences.
OBJECTIVE: The intent of the study was to determine the feasibility and efficacy of a 12-week physical activity promotion program
targeting children, which was delivered to parents through mobile phones.
METHODS: Potential participants were recruited through advertisements...
Soils in household environments in low- and middle-income countries may play an important role in the persistence, proliferation, and transmission of Escherichia coli. Our goal was to investigate the risk factors for detection, survival, and growth of E. coli in soils collected from household plots. E. coli was enumerated in...
Understanding the drivers and implications of anthropogenic disturbance of ecological connectivity is a key concern for the conservation of biodiversity and 50 ecosystem processes. Here, we review human activities that affect the movements and dispersal of aquatic organisms, including damming of rivers, river regulation, habitat loss and alteration, human-assisted dispersal...
