Interaction of vegetation control and fertilization on conifer species across the Pacific Northwest

Creator:: Rose, Robin and Ketchum, J. Scott
Abstract:: An experiment evaluating three levels of vegetation competition control (no control, 1.5 m2 of vegetation control, and 3.3 m2 of vegetation control), each with two fertilization treatments (fertilization at the time of planting with complete slow-release fertilizer (Woodace® IBDU), or no fertilization), was installed at five sites. Two of these...

Conifer response to three silvicultural treatments in the Oregon Coast Range foothills

Creator:: Walter, Scott T. and Maguire, Chris C.
Abstract:: This study assessed growth, condition, and mortality of residual trees one decade after harvest across three silvicultural treatments in thirty 85- to 125-year-old Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the Oregon Coast Range foothills. Group-selection cuts had 33% of the entire stand volume extracted as patches approximately 0.2–0.8 ha...

Seasonal variation of photosynthetic model parameters and leaf area index from global Fluxnet eddy covariance data

Creator:: Groenendijk, M., Dolman, A. J., Ammann, C., Arneth, A., Cescatti, A., Dragoni, D., Gash, J. H. C., Gianelle, D., Gioli, B., Kiely, G., Knohl, A., Law, B. E., Lund, M., Marcolla, B., van der Molen, M. K., Montagnani, L., Moors, E., Richardson, A. D., Roupsard, O., Verbeeck, H., and Wohlfahrt, G.
Abstract:: Global vegetation models require the photosynthetic parameters, maximum carboxylation capacity (V[subscript cm]), and quantum yield (alpha) to parameterize their plant functional types (PFTs). The purpose of this work is to determine how much the scaling of the parameters from leaf to ecosystem level through a seasonally varying leaf area index...

A model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesis

Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Evaluating theories of drought-induced vegetation mortality using a multimodel– experiment framework

Creator:: McDowell, Nate G., Gehres, Nathan, Limousin, Jean Marc, Macalady, Alison, Martínez-Vilalta, Jordi, Mencuccini, Maurizio, Plaut, Jennifer A., Ogée, Jérôme, Robert E., Pangle, Rasse, Daniel P., Ryan, Michael G., Fisher, Rosie A., Sevanto, Sanna, Waring, Richard H., Williams, A. Park, Yepez, Enrico A., Pockman, William T., Xu, Chonggang, Domec, Jean-Christophe, Holtta, Teemu, Mackay, D. Scott, Sperry, John S., Boutz, Amanda, and Dickman, Lee
Abstract:: Model–data comparisons of plant physiological processes provide an understanding of mechanisms underlying vegetation responses to climate. We simulated the physiology of a pi~non pine–juniper woodland (Pinus edulis–Juniperus monosperma) that experienced mortality during a 5 yr precipitation-reduction experiment, allowing a framework with which to examine our knowledge of drought-induced tree mortality....

Wave Impact Study on a Residential Building

Creator:: van de Lindt, John W., Gupta, Rakesh, Cox, Daniel T., and Wilson, Jebediah S.
Abstract:: Recent natural disasters around the world including both tsunamis and hurricanes, have highlighted the inability of wood buildings to withstand wave and surge loading during these extreme events. Little is known about the interaction between coastal residential light-frame wood buildings and wave and surge loading because often little is left...

Evidence for Mate Guarding Behavior in the Taylor's Checkerspot Butterfly

Creator:: Bennett, Victoria J., Smith, Winston P., and Betts, Matthew G.
Abstract:: Discerning the intricacies of mating systems in butterflies can be difficult, particularly when multiple mating strategies are employed and are cryptic and not exclusive. We observed the behavior and habitat use of 113 male Taylor’s checkerspot butterflies (Euphydryas editha taylori). We confirmed that two distinct mating strategies were exhibited; patrolling...

Effectiveness of Small Onshore Seawall in Reducing Forces Induced by Tsunami Bore: Large Scale Experimental Study

Creator:: Oshnack, Mary Elizabeth, Aguíñiga, Francisco, Cox, Daniel, Gupta, Rakesh, and van de Lindt, John
Abstract:: Tsunami force and pressure distributions on a rigid wall fronted by a small seawall were determined experimentally in a large-scale wave flume. Six different seawall heights were examined, two of which were exposed to a range of solitary wave heights. The same experiment was done without a seawall for comparison....

The growing season carbon balance of a sub-boreal clearcut 5 years after harvesting using two independent approaches to measure ecosystem CO₂ flux

Creator:: Pypker, Thomas G. and Fredeen, Arthur L.
Abstract:: From 27 June to 3 September 1999, CO2 fluxes from a 5-year-old, 84.15-ha vegetated clearcut in sub-boreal British Columbia were measured using a Bowen ratio energy balance (BREB) system and a second approach (the component model) that was based on scaled up CO2-flux measurements from belowground and plants (spruce seedlings...
