Succession and organization of rocky intertidal zone surfgrass beds
(Phyllospadix scouleri Hook) were examined experimentally at two sites
on the Oregon coast. The interaction of three attributes of the plant
-- high persistence, high preemption, and slow recovery -- strongly
influences the organization of surfgrass beds. Permanent plots indicate
that...
Air temperatures and soil temperatures at the surface, two inches,
and four inches under a grass cover were recorded over a 93 day period.
These data were used along with other temperature data from bare soil
in the construction of three sets of models for the prediction of
maximum and...
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...
