Evidence for xylem embolism as a primary factor in dehydration-induced declines in leaf hydraulic conductance

Creator:: Johnson, Daniel M., McCulloh, Katherine A., Woodruff, David R., and Meinzer, Frederick C.
Abstract:: Hydraulic conductance of leaves (K[subscript leaf]) typically decreases with increasing water stress and recent studies have proposed different mechanisms responsible for decreasing K[subscript leaf]. We measured K[subscript leaf] concurrently with ultrasonic acoustic emissions (UAEs) in dehydrating leaves of several species to determine whether declining K[subscript leaf] was associated with xylem...

Reconciling estimates of the contemporary North American carbon balance among terrestrial biosphere models, atmospheric inversions, and a new approach for estimating net ecosystem exchange from inventory-based data

Creator:: Hayes, Daniel J., Turner, David P., Stinson, Graham, McGuire, A. David, Wei, Yaxing, West, Tristram O., Heath, Linda S., de Jong, Bernardus, McConkey, Brian G., Birdsey, Richard A., Kurz, Werner A., Jacobson, Andrew R., Huntzinger, Deborah N., Pan, Yude, Post, W. Mac, and Cook, Robert B.
Abstract:: We develop an approach for estimating net ecosystem exchange (NEE) using inventory-based information over North America (NA) for a recent 7-year period (ca. 2000–2006). The approach notably retains information on the spatial distribution of NEE, or the vertical exchange between land and atmosphere of all non-fossil fuel sources and sinks...

Effects of silvicultural practices on carbon stores in Douglas-fir – western hemlock forests in the Pacific Northwest, U.S.A.: results from a simulation model

Creator:: Harmon, Mark E. and Marks, Barbara
Abstract:: We used a new model, STANDCARB, to examine effects of various treatments on carbon (C) pools in the Pacific Northwest forest sector. Simulation experiments, with five replicates of each treatment, were used to investigate the effects of initial conditions, tree establishment rates, rotation length, tree utilization level, and slash burning...

Activity Substitutability and Degree of Specialization among Deer and Elk Hunters in Multiple States

Creator:: Needham, Mark D. and Vaske, Jerry J.
Abstract:: This article examines relationships between hunter specialization and activity substitutability. Data were obtained from a mail survey of 6,983 deer hunters in eight states and 2,584 elk hunters in three states. Activity substitutability was measured by asking what activity would provide the same satisfaction as deer or elk hunting. Between...

Voluntary Environmental Programs at an Alpine Ski Area: Visitor Perceptions, Attachment, Value Orientations, and Specialization

Creator:: Needham, Mark D. and Little, Christopher M.
Abstract:: This article examines visitor perceptions of voluntary environmental programs (VEPs) at the Mt. Bachelor ski area in Oregon, USA by examining what they know about VEPs, how these programs influence motivations to visit this area currently and in the future, and how place attachment, value orientations, and specialization influence these...

Recreation Specialization and Related Concepts in Leisure Research

Creator:: Needham, Mark D., Scott, David, and Vaske, Jerry J.
Abstract:: More than 40 years have passed since Shafer (1969) challenged the existence of the “average camper.” Recognizing that participants in recreation activities are heterogeneous in their commitments and interests, researchers have emphasized the importance of differentiating users into meaningful homogeneous subgroups. In his seminal article, Bryan (1977) coined the concept...

Height-diameter equations for six species in the coastal regions of the Pacific Northwest

Creator:: Hanus, Mark L., Marshall, David D., and Hann, David W.
Abstract:: Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific Northwest. Foresters can use these “height–diameter” equations to avoid the time-consuming task of measuring heights of all individual trees in an inventory,...

Predicting height for undamaged and damaged trees in southwest Oregon

Creator:: Hanus, Mark L., Hann, David W., and Marshall, David D.
Abstract:: Equations for predicting tree height as a function of diameter outside bark at breast height are presented for various tree species common to southwest Oregon. Data for damaged and undamaged trees were analyzed with weighted nonlinear regression techniques. The effects of specific damaging agents and their severity on the height-diameter...

Skyline thinning production and costs : experience from the Willamette Young Stand Project

Creator:: Kellogg, L. D. (Loren D.), Miller, Mark E., Olsen, Eldon D., and Oregon State University. Forest Research Laboratory
Abstract:: Production rates and costs for skyline harvesting were examined over a range of residual thinning intensities, operational methods, and sites. The sites included three stands of 40- to 50-yr-old Douglas-fir on the Willamette National Forest in the Cascade Mountains of Oregon. Three silvicultural treatments were studied at two sites, and...

Equations for predicting height-to-crown-base, 5-year diameter-growth rate, 5-year height-growth rate, 5-year mortality rate, and maximum size-density trajectory for Douglas-fir and western hemlock in the coastal region of the Pacific Northwest

Creator:: Hann, David W., Marshall, David D., Hanus, Mark L., and Oregon State University. Forest Research Laboratory
Abstract:: Using existing permanent research plot data, we developed equations for predicting height-to-crown-base (HCB), 5-yr diametergrowth rate (delta D), 5-yr height-growth rate (delta H), 5-yr mortality rate (PM), and the maximum size-density trajectory for Douglasfir and western hemlock in the coastal region of the Pacific Northwest. With the exception of the...
