We used wavelet analyses of sea surface height (SSH) from >13 years of satellite
altimeter data to characterize the variability in mesoscale circulation in the northern
California Current (35°N–49°N) and explore the mechanisms of variability. We defined
‘‘mesoscale’’ circulation as features, such as eddies and filaments, which have 50- to...
Oregon's forestry industry has and will continue to be a vital component of Oregon's economy, with twenty-two percent of Oregon's 1986 gross state product and thirty-nine percent of Oregon's 1986 gross manufacturing product related the forestry goods. An integral component to proper management of Oregon's forestry lands is Sustaining the...
A pair of hydrographic sections, one north and one south of Cape Blanco at 42.9N, was sampled in five summers (1998–2000 and 2002–2003). The NH line at 44.6N lies about 130 km south of the Columbia River, and spans a relatively wide shelf off Newport, Oregon. The CR line at...
Cognitive and other neural processes emerge from the interactions be- tween neurons. Major advances have been made in studying networks in which the interac- fions occur instantaneously by means ofgraded synapses (Guckenheimer and Rowat, I 997). In other networks, the interaction between neurons involves time-delayed signals (action potentials or spikes)...
The history of entomopathogenic nematology is briefly reviewed. Topic selections include early descriptions of members
of Steinernema and Heterorhabditis, how only morphology was originally used to distinguish between the species; descriptions of the
symbiotic bacteria and elucidating their role in the nematode- insect complex, including antibiotic properties, phase variants, and...
The general circulation model of Bryan (1969), modified by the introduction of open boundary
conditions at the Drake Passage and between Africa and Antarctica, has been used to study the mass
and heat budgets of the South Atlantic Ocean. The model was initialized with the climatological annual
mean values of...
The goal of the Pacific Ocean Boundary Ecosystem and Climate Study
(POBEX) was to diagnose the large-scale climate controls on regional transport
dynamics and lower trophic marine ecosystem variability in Pacific Ocean boundary
systems. An international team of collaborators shared observational and eddy-resolving
modeling data sets collected in the Northeast...
Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...
