  • Susceptibility of riparian soil invertebrates to the herbicide triclopyr

    Creator:
    Moran, Patrick (Patrick William)
    Abstract:
    Riparian zones of Pacific Northwest forests have high species diversity and abundance and act as an important interface between the aquatic and terrestrial ecosystems. In addition, riparian zones comprise a significant portion of the total buffer zone established during commercial forest production to protect aquatic ecosystems from adjacent management activities....

  • Root decomposition in three coniferous forests : effects of substrate quality, temperature, and moisture

    Creator:
    Chen, Hua
    Abstract:
    Controls of substrate quality, temperature, and moisture on woody root decomposition in the Pacific Northwest were explored using chronosequences, time series, laboratory incubations, and simulation modeling approaches at three sites: Cascade Head (CAH), H. J. Andrews (HJA), and Pringle Falls Experimental Forests (PRF). In the chronosequence study, a structural component-oriented...

  • Mycorrhizal and other root endophytic fungi of lupines in the Pacific Northwest

    Creator:
    O'Dell, Thomas E.
    Abstract:
    We investigated the root endophytic fungi of lupine using four approaches: (1) occurrence of fungal colonization in field-collected roots; (2) growth response of L. latifolius to inoculation with two types of fungi; (3) structure of root colonizations of Pinus and Lupinus by Phialocephala fortinii, a septate endophytic fungus of lupine;...
