Effects of Vegetation Management on Wood Properties and Plant Water Relations of Four Conifer Species in the Pacific Northwest of the USA

Creator:: Aernouts, Joyce, Gonzalez-Benecke, Carlos A., and Schimleck, Laurence R.
Abstract:: In plantation forests, competition from unwanted vegetation may reduce survival and negatively impact tree growth. The goal of this study was to examine the influence of vegetation management treatments on plant water relations and wood properties. Control trees (no treatment) were compared to trees subjected to post-planting competing vegetation control...

Local and General Above-Ground Biomass Functions for Pinus palustris Trees

Creator:: Gonzalez-Benecke, Carlos A., Zhao, Dehai, Samuelson, Lisa J., Martin, Timothy A., Leduc, Daniel J., and Jack, Steven B.
Abstract:: There is an increasing interest in estimating biomass for longleaf pine (Pinus palustris Mill.), an important tree species in the southeastern U.S. Most of the individual-tree allometric models available for the species are local, relying on stem diameter outside bark at breast height (DBH) and total tree height (HT), but...

Surface-based GPR underestimates below-stump root biomass

Creator:: Butnor, John R., Samuelson, Lisa J., Stokes, Thomas A., Johnsen, Kurt H., Anderson, Peter H., and González-Benecke, Carlos A.
Abstract:: Aims: While lateral root mass is readily detectable with ground penetrating radar (GPR), the roots beneath a tree (below-stump) and overlapping lateral roots near large trees are problematic for surface-based antennas operated in reflection mode. We sought to determine if tree size (DBH) effects GPR root detection proximal to longleaf...

Understory plant biomass dynamics of prescribed burned Pinus palustris stands

Creator:: Gonzalez-Benecke, C. A., Samuelson, L. J., Stokes, T. A., Cropper, W. P., Jr., Martin, T. A., and Johnsen, K. H.
Abstract:: Longleaf pine (Pinus palustris Mill.) forests are characterized by unusually high understory plant species diversity, but models describing understory ground cover biomass, and hence fuel load dynamics, are scarce for this fire-dependent ecosystem. Only coarse scale estimates, being restricted on accuracy and geographical extrapolation, are available. We analyzed the dynamics...

Modeling the effects of forest management on in situ and ex situ longleaf pine forest carbon stocks

Creator:: Gonzalez-Benecke, C. A., Samuelson, L. J., Martin, T. A., Cropper, W. P., Jr., Johnsen, K. H., Stokes, T. A., Butnor, J. R., and Anderson, P. H.
Abstract:: Assessment of forest carbon storage dynamics requires a variety of techniques including simulation models. We developed a hybrid model to assess the effects of silvicultural management systems on carbon (C) budgets in longleaf pine (Pinus palustris Mill.) plantations in the southeastern U.S. To simulate in situ C pools, the model...

Deforestation Trends of Tropical Dry Forests in Central Brazil

Creator:: Bianchi, Carlos A. and Haig, Susan M.
Abstract:: Tropical dry forests are the most threatened forest type in the world yet a paucity of research about them stymies development of appropriate conservation actions. The Paran~a River Basin has the most significant dry forest formations in the Cerrado biome of central Brazil and is threatened by intense land conversion...

Agave salmiana Plant Communities in Central Mexico as Affected by Commercial Use

Creator:: Martinez Salvador, Martin, Mata-Gonzalez, Ricardo, Morales Nieto, Carlos, and Valdez-Cepeda, Ricardo
Abstract:: Agave salmiana is a native plant species harvested for the commercial production of mezcal (Agave spirits) in the highlands of central Mexico. The objective of this study was to identify vegetation changes in natural communities where A. salmiana has been differentially harvested for commercial purposes. Three plant community categories were...

Annual reversible plasticity of feeding structures: cyclical changes of jaw allometry in a sea urchin

Creator:: Ebert, Thomas A., Hernández, José Carlos, and Clemente, Sabrina
Abstract:: A wide variety of organisms show morphologically plastic responses to environmental stressors but in general these changes are not reversible. Though less common, reversible morphological structures are shown by a range of species in response to changes in predators, competitors, or food. Theoretical analysis indicates that reversible plasticity increases fitness...

Decomposition of heterogeneous organic matter and its long-term stabilization in soils

Creator:: Sierra, Carlos A., Harmon, Mark E., and Perakis, Steven S.
Abstract:: Soil organic matter is a complex mixture of material with heterogeneous biological, physical, and chemical properties. Decomposition models represent this heterogeneity either as a set of discrete pools with different residence times or as a continuum of qualities. It is unclear though, whether these two different approaches yield comparable predictions...

Carbon balance on federal forest lands of Western Oregon and Washington: The impact of the Northwest Forest Plan

Creator:: Krankina, Olga N., Harmon, Mark E., Schnekenburger, Frank, and Sierra, Carlos A.
Abstract:: The management of federal forest lands in the Pacific Northwest (PNW) region changed in early 1990s when the Northwest Forest Plan (NWFP) was adopted with the primary goal to protect old-growth forest and associated species. A major decline in timber harvest followed, extending an earlier downward trend. The historic and...
