Acoustical localization of concealed prey by the diurnal harrier (Circus cyaneus)

Creator:: Rice, William Richard
Abstract:: I experimentally examined the adaptive significance of the anatomical and behavioral convergence between the harrier (Circus cyaneus, also refered to as the marsh hawk) and certain owls that are capable of capturing prey in total darkness. Anatomically, both the harrier and owls have evolved a sound collecting facial ruff (a...

The influence of soil compaction on early conifer growth in the southern Washington Cascades

Creator:: Robbins, Richard William
Abstract:: This study evaluated the effect of soil compaction on the growth of natural regeneration on volcanic ash-influenced soils in the southern Washington Cascades. Growth of 9 to 18 year-old sapling-. sized Ponderosa pine (Pinus ponderosa Laws.) was studied on sites ranging from 915 to 1006 m elevation in an area...

Effects of early season immigration on acaricide resistance of Tetranychus urticae Koch on strawberry in the California Pajaro and Salinas valleys

Creator:: Miller, Richard W. (Richard William), 1958-
Abstract:: In the Pajaro Valley near Watsonville, California, twospotted spider mite (Tetranychus urticae Koch) populations were surveyed in 1983 and '84 to detect the influence of immigrants from nursery plants or surrounding vegetation on subsequent resistance development to cyhexatin and formetanate in strawberry fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...

Creator:: Gilbert, William E., Huyer, Adriana, 1945-, and Schramm, Richard E.
Abstract:: CTD observations were made along the CODE Central Line, extending offshore toward 225°T from the California coast at 38°40'N, during 12-14 April, 1981. The complete section with nine stations was occupied twice; the offshore portion was occupied three times. The maximum sampling depth was 1000 m. This report includes a...

Submersible observations of deep-reef fishes of Heceta Bank, Oregon

Creator:: Pearcy, William G., Stein, David L., Hixon, Mark Anthony, Pikitch, Ellen K., Barss, William H., and Starr, Richard M.
Abstract:: Rockfishes, Sebastes spp.. were the most numerous and speciose fishes seen during 16 submersible dives from 64 to 305 m depth in the vicinity of Heceta Bank off the coast of Oregon. Dense schools of juvenile rockfishes and large yellowtail rockfish, S. flavidus, were observed only over rocky, high relief...
