Effects of prescribed cattle grazing on reforestation in Oregon's southern Cascades

Creator:: Karl, Michael G.
Abstract:: Reforesting harvested lands in southwestern Oregon has been difficult because of low rainfall, high evaporative demand, and competitive understory vegetation. Herbicides have been a preferred method to control competing vegetation but herbicide use on federal lands was curtailed in 1984. As a result, interest in livestock grazing as a vegetation...

Characterization of Triticum turgidum ssp. carthlicum (Nevski) Löve et Löve by discriminant analysis

Creator:: Vieira, Luiz Gonzaga E.
Abstract:: Forty-six morphological characters were used in a study of Triticum turgidum ssp. carthlicum (2n = 28) and specimens of carthlicum-like forms of Triticum aestivum ssp. vulgare (2n = 42). The morphological variation patterns within these groups were examined using stepwise discriminant analysis. These results indicate that specimens studied could be...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...

Sound production in Leperisinus oregonous Blackman and L. californicus Swaine (Coleoptera:Scolytidae)

Creator:: Vernoff, Suellen
Abstract:: Both Leperisinus oregonus and L. californicus are bark beetle species which emerge from Fraxinus latifolia brood logs as sexually immature adults and disperse to living ash. Occasional field observations suggest that, for overwintering and maturation feeding, L. oregonus enter trunks and branches, whereas L.; californicus enter twig crotches, buds and...
