Fungal hyphae are among the most highly polarized cells. Hyphal polarized
growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily
in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex
is required for tethering of secretory vesicles to the apical plasma membrane. We...

Marine sponges are vital components of benthic and coral reef ecosystems, providing
shelter and nutrition for many organisms. In addition, sponges act as an essential carbon
and nutrient link between the pelagic and benthic environment by filtering large quantities
of seawater. Many sponge species harbor a diverse microbial community (including...

Trophic interactions within and among species vary widely across spatial scales and species’ ontogeny. However, the drivers and implications of this variability are not well understood. Juvenile Chinook salmon Oncorhynchus tshawytscha have a wide distribution, ranging from northern California to the eastern Bering Sea in North America, but it is...

This study details the use of printing and other additive processes to fabricate a novel amperometric glucose sensor. The sensor was
fabricated using a Au coated 12.7 μm thick polyimide substrate as a starting material, where micro-contact printing, electrochemical
plating, chloridization, electrohydrodynamic jet (e-jet) printing, and spin coating were used...

Changes in soil C and N pools following wildfire are
quite varied, but there is little understanding of the
causes of the variation. We examined how the
legacies of prefire ecosystem structure may explain
the variation in soil trajectories during the first
decade following wildfire. Five years prior to
wildfire...

Siletzia is a basaltic Paleocene and Eocene
large igneous province in coastal Oregon,
Washington, and southern Vancouver Island
that was accreted to North America in the
early Eocene. New U-Pb magmatic, detrital
zircon, and ⁴⁰Ar/³⁹Ar ages constrained by
detailed field mapping, global nannoplankton
zones, and magnetic polarities allow correlation
of...

Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) growth in the Pacific Northwest is affected by climatic, edaphic factors and Swiss needle cast (SNC) disease. We examine Douglas-fir growth responses to temperature, dew point deficit (DPD), soil moisture, and SNC using time series intervention analysis of intra-annual tree-ring width data collected...

The middle Deschutes River between Bend, Oregon and Lake Billy Chinook typically experiences critically low flows during the irrigation season. Commercial agriculture in the North Unit Irrigation District and Central Oregon Irrigation District is one major user of Deschutes River water. The overall objective of this research was to estimate...
