Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

A stand management strategy for young western hemlock-Sitka spruce forests

Creator:: Kellogg, L. D. (Loren D.)
Abstract:: Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These stands are ready for a first commercial thinning entry, however, the costs and benefits of such entries and resulting impacts at...

The ecology and management of invasive plant species on tropical islands

Creator:: Hooper, Carolina
Abstract:: Tropical island ecosystems have proven to be inordinately vulnerable to invasions by exotic plants and animals. Today these islands only contain small remnant populations of the original flora and fauna, and these populations are facing increasing pressure from invasive plants. This paper attempts to answer four important questions whose solutions...

Repeated sequences associated with inversions and length mutations in the chloroplast genomes of Pseudotsuga and Pinus

Creator:: Hipkins, Valerie D.
Abstract:: To help understand the mechanisms of conifer chloroplast genome evolution, we characterized the nucleotide sequences of Douglas-fir (Pseudotsuga menziesiz) and Monterey pine (Pinus radiata) chioroplast DNA that are associated with a length mutation hotspot and inversion. The chloroplast DNA ofthese two conifers are characterized by shared large inversions that are...

Relationships between plant associations and environment within McDonald-Dunn Forest

Creator:: Leavell, Daniel M.
Abstract:: I studied the relationship of environmental variables to six plant associations on McDonald and Paul M. Dunn Forests. Indirect gradient analysis was used to determine relationships. The plant associations were developed in a companion study by C.J. Hubbard (1991). McDonald-Dunn Forests are located north and northwest of Corvallis, Oregon. The...

A plant association classification for McDonald-Dunn Forest

Creator:: Hubbard, Connie J.
Abstract:: The purpose of this study was to develop a plant association classification for the mature coniferous forests of the McDonald and Paul M. Dunn Research Forests. A secondary objective was to quantify diversity within the plant associations. This Forest is approximately 11,000 acres and is located 6 miles to the...

Snag longevity, bird use of cavities, and conifer response across three silvicultural treatments in the Oregon Coast Range

Creator:: Walter, Scott T.
Abstract:: In the interest of meeting multiple forest management goals that include maintenance of wildlife, particularly cavity-nesting birds, uneven-aged silvicultural treatments are used increasingly in the Pacific Northwest. However, questions remain regarding the responses of cavity-nesting birds and residual green trees to different harvest intensities and patterns. To study these issues,...

Effects of shade on performance and chlorophyll fluorescence of four Pacific Northwest seedling conifer species

Creator:: Khan, Shafiqur Rehman
Abstract:: The influence of shading intensity on performance, chlorophyll fluorescence emissions, the slope of the fluorescence induction curve, chlorophyll contents, and stomatal conductance of four Pacific Northwest conifer species [ponderosa pine (Pinus ponderosa Laws.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), western redcedar (Thujaplicata Donn.), and western hemlock (Tsuga heterophylla (Raf.) Sarg.)] was...

Physiology and genetics of drought hardiness in coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) seedlings

Creator:: Lomas, M. Christine
Abstract:: Physiology and genetics of drought hardiness were investigated in two-year-old coastal Douglas-fir seedlings from 39 full-sib families obtained from coastal British Columbia and grown at Oregon State University, Corvallis, Oregon. The seedlings were subjected to three drought treatments (control, moderate, and severe drought) in their second growing season (June through...
