Comment on ‘‘Post-Wildfire Logging Hinders Regeneration and Increases Fire Risk’’

Creator:: Newton, M., Fitzgerald, S., Rose, R. R., Adams, P. W., Tesch, S. D., Sessions, J., Atzet, T., Powers, R. F., and Skinner, C.
Abstract:: Donato et al. (Brevia, 20 January 2006, p. 352) concluded that logging after wildfire kills natural regeneration and increases fire risk. We argue that their paper lacks adequate context and supporting information to be clearly interpreted by scientists, resource managers, policy-makers, and the public.

Mapping mortality following a long-term drought in a pinyon-juniper ecosystem in Arizona and New Mexico using Landsat data

Creator:: Kirschbaum, Alan A.
Abstract:: Protracted drought in the southwest U.S. has had significant impacts on the region’s keystone ecosystem, the pinyon-juniper (PJ) woodlands. Drought conditions in 9 of the last 10 years, exacerbated by extreme drought in one year, stressed the pinyon pine (Pinus edulis) trees, making them highly vulnerable to native ips beetles...

Pollen contamination trends in a maturing Douglas-fir seed orchard

Creator:: Adams, W. T., Hipkins, Valerie D., Burczyk, J., and Randall, W. K.
Abstract:: Pollen contamination was investigated in one block (block 4) of a 10-block Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seed orchard complex in western Oregon. Blocks (25 clones each) represent different breeding zones; thus, contaminant pollen sources not only included the adjacent natural stand of Douglas-fir, but also other blocks within the...

The CP4 transgene provides high levels of tolerance to Roundup® herbicide in field-grown hybrid poplars

Creator:: Meilan, R., Han, K.-H., Ma, C., DiFazio, Stephen P., Eaton, J. A., Hoien, E. A., Stanton, B. J., Crockett, R. P., Taylor, M. L., James, R. R., Skinner, J. S., Jouanin, L., Pilate, G., and Strauss, S. H.
Abstract:: We tested two genes together in hybrid poplars (genus Populus), CP4 and GOX, for imparting tolerance to glyphosate (the active ingredient in Roundup® herbicide). Using Agrobacterium-based transformation, 80 independent transgenic lines (i.e., products of asexual gene transfer) were produced in a variety of hybrid poplar clones (40 lines in Populus...

Influence of Bravo fungicide applications on wood density and moisture content of Swiss needle cast affected Douglas-fir trees

Creator:: Johnson, G. R., Gartner, Barbara L., Maguire, Doug, and Kanaskied, Alan
Abstract:: Wood density, moisture content, tracheid width and cell wall size were examined in trees from plots that were sprayed for 5 years with chlorothalonil (Bravo®) fungicide to reduce the impact of Swiss needle cast (SNC) and from trees in adjacent unsprayed plots. The unsprayed (more heavily diseased) trees had significantly...

Within-stem variation of respiration in Pseudotsuga menziesii (Douglas-fir) trees

Creator:: Pruyn, Michele L., Gartner, Barbara L., and Harmon, Mark E.
Abstract:: • A technique for measuring in vitro respiration was investigated to understand why rates were higher than those reported in vivo and to elucidate trends within mature Pseudotsuga menziesii (Douglas‐fir) trees. • Extracted increment cores were divided into 3–4 radial depths and a gas chromatograph was used to compare respiration...

A comparison of daily water use estimates derived from constant-heat sap-flow probe values and gravimetric measurements in pot-grown saplings.

Creator:: McCulloh, Katherine A., Winter, Klaus, Meinzer, Frederick C., Garcia, Milton, Aranda, Jorge, and Lachenbruch, Barbara
Abstract:: Use of Granier-style heat dissipation sensors to measure sap flow is common in plant physiology, ecology and hydrology. There has been concern that any change to the original Granier design invalidates the empirical relationship between sap flux density and the temperature difference between the probes. Here, we compared daily water...

Disturbance and landscape history as a reference for evaluating forest management effects at a regional scale : examples from the Coast Range of Oregon, USA

Creator:: Nonaka, Etsuko
Abstract:: History is an invaluable source of information to understand and evaluate management influences on contemporary ecosystems and landscapes. The first two chapters (Chapters 2 and 3) explored the concept of historical range of variability (HRV) in landscape structure and stand structure using a stochastic fire simulation model to simulate presettlement...

Time-based nitrogen availability and risk of Taeniatherum caput-medusae (L.) Nevski invasion in central Oregon

Creator:: Stubbs, Michelle M.
Abstract:: During the last century, fire suppression, grazing, and climate change have caused sagebrush grasslands to be altered in both function and form; juniper and sagebrush dominate the landscape at the expense of herbaceous plants. Management efforts to reduce juniper and sagebrush overstory in order to enhance herbaceous components of the...
