A number of researchers view farmers’ markets as an appropriate vehicle for
re-embedding food markets into communities (O’Hara & Stagl, 2001, Feenstra, 2002,
Lyson, 2005). Amidst astounding growth in the number of farmers’ markets in the
United States in recent decades, many markets struggle and fail. Recent research
suggests that...
This thesis examines the mechanisms that couple the monthly-averaged
atmospheric boundary layer (ABL) to open-ocean sea surface temperature (SST)
perturbations on scales of 50-500 km. The observed positive correlation between
surface wind speed anomalies and SST anomalies is successfully simulated using
the Weather Research and Forecasting (WRF) model.
In numerical...
Seasonal abundance and life history traits were compared between populations of the brine fly Ephydra (Hydrokyrus) hians Say (Diptera:Ephydridae), from two western Great Basin alkaline salt lakes. Abert Lake, Oregon, has a relatively low salinity (20-30 g/1 total dissolved solids) and more co-inhabitant benthic species than the higher salinity Mono...
Larval mortality of leafcutting bee, Megachile pacifica (Panzer)
(= rotundata (F.)), is high, usually exceeding 50%. Parasites and
predators are not a limiting factor in the survival of the progeny.
The disease chalk brood has been an important mortality factor since
1974. Inadequate food supply, pollen and nectar, may affect...
