The studies to be reported herein were initiated following a cursory search of the literature concerning the lakes of the State of Oregon. Few substantive lirnnological works were located. More detailed efforts added only a few obscure references. Since change is the basic axium of ecology, there was concern for...
Western wildcucumber (Marah oreganus [T. & G.]
Howell), also known as Oldman- in-the-ground, Echinocystis
oregana Cogn., is a perennial with stems that
regrow each spring from a huge woody root.
Stems become long, and they climb with the aid of branched
tendrils. Leaves are alternate, lobed, and up to 6...
A low-power (<10 mW), physically small (15.6 cm long × 3.2 cm diameter), lightweight (600 g Cu; alternatively, 200 g Al), robust, and simply calibrated pitot-static tube to measure mean speed and turbulence dissipation (ε ) is described and evaluated. The measurement of speed is derived from differential pressure via...
The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...

Two distinct nocturnal subcanopy flow regimes are observed beneath a tall (16 m) open pine forest canopy. The first is characterized by weaker mixing, stronger stability, westerly downslope flow decoupled from the flow above the canopy and much smaller than expected ecosystem respiration from the eddy flux plus storage measurements...
