C-methyltransferase
(HIOMT) in chinook salmon (Oncorhynchus
tshawytscha). Various body tissues, as well as several
morphological brain divisions were tested for the presence
of HIOMT. Activity was found in the retina, the dorsal
portion of the diencephalon, and in the pineal gland of
chinook. However, the activity was significantly higher
in...
No studies have evaluated the effects of limited vehicle access on movements, survival and habitat use of Roosevelt
elk (Cervus elaphus roosevelti) . We installed twenty gates, restricting motorized vehicle access by the public in
seven discrete Road Management Areas (RMAs), comprising 35% of the study area. We radio-tracked 31...
The purpose of this study was to assess how growth of young to mature Douglas-fir
(Pseudotsuga menziesii (Mirb.) Franco) and western hemlock (Tsuga heterophylla (Raf.) Sar.)
in mixed stands was influenced by the presence of residual trees. Fourteen paired plots with
and without residual trees were examined in a retrospective...
The parallel implementation of a large number of functional units is necessary for
any industrial scale microfluidic process. The concept of a 'numbering up'
strategy where a single highly optimized functional unit that has a low individual
production is replicated a large number of times to create a device that...
Despite the critical ecological roles of structural features in forests, ecologically
relevant quantitative measures of structure that allow comparisons among forest stands
are still limited. A new index, the structural complexity index (SCI), was developed to
characterize and compare the structural complexity of different forests. Point patterns
of stem-mapped trees...
Madden–Julian oscillation (MJO) wind and convection anomalies are locally amplified over the northeast Pacific warm pool during June–November. Composite analysis using NCEP reanalysis data indicates that perturbation available potential energy (PAPE) production through the positive correlation of intraseasonal temperature and convective diabatic heating anomalies supports the local intensification of MJO-related...
Intraseasonal precipitation variability over the northeast Pacific warm pool during June–October in the National Center for Atmospheric Research Community Atmosphere Model 2.0.1 with a relaxed Arakawa–Schubert convection parameterization is found to be strongly sensitive to wind-induced variations in surface latent heat flux. A control simulation with interactive surface fluxes produces...
Tropical intraseasonal variability in the eastern North Pacific during June–September of 2000–03 is
analyzed using satellite and buoy observations. Quick Scatterometer ocean vector winds and the Tropical
Rainfall Measuring Mission (TRMM) precipitation indicate that periods of anomalous surface westerly flow
over the east Pacific warm pool during a summertime intraseasonal...
The acorn woodpecker is among the most common primary cavity nesting bird of the Oregon white oak woodlands. In most of
their range, acorn woodpeckers are dependent on granaries for acorn storage, yet little is known about their selection of granary
sites. We compared habitat characteristics within 12 m of...
