Factors affecting conifer regeneration and community structure after a wildfire in western Montana

Creator:: Toth, Barbara L.
Abstract:: A severe wildfire burned 454 hectares of a second-growth Douglas-fir forest in 1977 on a north-facing slope in Pattee Canyon, near Missoula, Montana. The slope was aerially seeded with a grass mixture, from which Dactylis glomerata established best. Community structure, conifer regeneration, and the impact of the seeded grass on...

The Ecology of Celtis reticulata Torr. (Netleaf hackberry) in Idaho

Creator:: DeBolt, Ann M.
Abstract:: The ecology of netleaf hackberry (Celtis reticulata Torr.) is poorly known throughout its broad western range. To gain some understanding of the species' basic ecology, three components of its life history were studied. First, seed germination requirements were analyzed under laboratory conditions. Second, hackberry population dynamics were evaluated from tree...

Lichen biomonitoring in southeast Alaska and western Oregon

Creator:: Derr, Chiska C.
Abstract:: Lichen sensitivity to air quality has been recognized in Europe for over 125 years: recently Federal agencies in this country have begun using lichens as air quality bioindicators. This study presents the results of three different approaches to air quality biomonitoring using lichens: (1) a lichen community analysis, (2) an...

Subalpine revegetation on backcountry campsites near Tuolumne Meadows, Yosemite National Park, California : third year results

Creator:: Moritsch, Barbara J.
Abstract:: The National Park Service initiated a backcountry campsite restoration project in 1987 to restore native vegetation on severely degraded campsites in three subalpine lake basins in Yosemite National Park. Restoration treatments included soil scarification, transplanting, manual seeding and site protection. Eight of the treated campsites were monitored in 1990 to...

Ecological implications of trout introductions to lakes of the Selway Bitterroot Wilderness, Idaho

Creator:: Bahls, Peter F.
Abstract:: The widespread introduction of trout to naturally fishless mountain lakes in the western United States has been accompanied by little research. The ecological role of trout populations occurring in 91 lakes of the central Selway Bitterroot Wilderness, Idaho, was examined with respect to 1) the sampling variability of biological and...

The species composition, density, and distribution of the littoral zooplankton assemblage in Crater Lake, Oregon

Creator:: Warncke, William Madara
Abstract:: The species compositions and densities of the littoral and pelagic zooplankton assemblages in Crater Lake were compared. The littoral and pelagic zooplankton assemblages of most lakes are typically different due to different habitat conditions in the two zones. The littoral zone of Crater Lake lacks many of the habitat characteristics,...

Pendent Usnea (Lichens; Ascomycetes; Parmeliaceae) in Western Oregon : taxonomy; morphological characters; and geographical distribution

Creator:: Pittam, Sherry K.
Abstract:: Pendent Usnea species were collected in western Oregon and examined. Character states, such as cortex-medulla-axis ratio; fibril length; papilla diameter; branching patterns; and presence or absence of fibrils, papillae, soredia, isidia; plus chemistry, were recorded and analyzed by inspection for differences. Historical names were researched in the literature. A comparison...

Developing models to predict favorable environments for rice blast

Creator:: Calvero, Silvino B.
Abstract:: Statistical analyses were used to develop predictive models of rice blast and to relate the favorability of environment to disease incidence and severity on different rice cultivars at five sites in Asia. The WINDOW PANE program was used to search for weather factors highly correlated with blast. Stepwise and r-square...
