Consumer-grade GPS units are a staple of modern field ecology, but the relatively large error radii reported by manufacturers (up to 10 m) ostensibly precludes their utility in measuring fine-scale movement of small animals such as insects. Here we demonstrate that for data collected at fine spatio-temporal scales, these devices...
The Douglas-fir beetle (Dendroctonus pseudotsugae Hopkins) can kill large numbers of Douglas-fir trees (Pseudotsuga menziesii (Mirbel) Franco) across a landscape during periods of population outbreaks. High-value individual trees and small stands can be protected from Douglas-fir beetle infestation during outbreaks by applying the anti-aggregation pheromone, MCH (3-methylcyclohex-2-en-1-one). MCH treatments are...
Background: Previous studies suggested that the professional identity of community college faculty is less than clearly articulated. Lack of clarity with regard to professional identity may have impacts in a number of areas, including recruitment, professional development, and the overall reputation of community colleges.
Purpose: To examine how community college...
Autophagy, a homeostatic degradation pathway, has a role in promoting cell survival under stress conditions, but can also promote cell death under conditions of sustained stress. This project investigates the cytotoxic potential of coibamide A and other natural products in autophagy-deficient and wild-type mouse embryonic fibroblasts (MEFs). Wild-type MEFs were...
Vertical transports of plankton, momentum, heat, and turbulence are modeled. A novel integration of high resolution turbulence and biophysical modeling is used to show the influence of a Kelvin-Helmholtz instability on the vertical migration of simple gyrotactic organisms. A viscous limit on mixing driven by shear turbulence is proposed. Large...
