The fungal ascomycete genus Otidea as represented in the Pacific Northwest of North America includes eight well known species and two poorly-known species. Cladistic analysis utilizing characters from ribosomal DNA and morphology allowed the development of a robust phylogenetic species concept for Otidea. The combination of characters from the ribosomal...
Historical concepts of Clavicipitaceae have included a broad range of species that display diverse morphologies, ecological modes and host associations. When subjected to multigene phylogenetic investigation of evolutionary history, the family was found to be polyphyletic, largely driven by diversity in the genus Cordyceps, previously containing over 400 taxa. The...
Torrubiella is a genus of entomopathogenic fungi in the Clavicipitaceae
(Ascomycota). Species of the genus produce superficial perithecia on a loose mat of
hyphae that forms directly on the host. The genus is estimated to contain about 70
species. Torrubiella is hypothesized to be a close relative of Cordyceps because...
This thesis is concerned with near source primary seismic waves generated by, the Gnome, Hardhat, Shoal and Haymaker underground nuclear explosions. Records of ground motion between 0.3 and 20.0 kilometers from the sources were analyzed in terms of displacement amplitude and energy variations with distance. The observed data have been...
A marine geophysical study using shallow seismic reflection, gravity and magnetic methods of investigation was done for an offshore area near Newport, Oregon. The area is bounded by the latitudes 44°1O' to 44°50' N. and longitudes 124°07' to 124°30' W. The interpretation of observational data showed that the geology of...
From measurements of thermal and electrical conductivities of
64 ocean sediment samples obtained from piston cores taken off the
Oregon Coast, and from 37 water-saturated sandstone samples analyzed
by Zierfuss and Van der Vliet (1956), as well as 51 thermal
conductivities and water contents of ocean sediments analyzed by
Ratcliffe...
Fourier transformed amplitudes of the compressional waves
recorded between 9° and 91° (about 1000 to 10,000 km) epicentral
distance from Gnome, Shoal, Haymaker,and Bilby underground
nuclear explosions have been compared with Fourier transformed
amplitudes of P waves measured at distances between 9.0 and
1 3. 0 km from the explosions....
