Modeling and dating glacier fluctuations and their relation to Pacific Ocean climate

Creator:: Anslow, Faron S.
Abstract:: This thesis presents the results of an investigation into the interactions between the present-day South Cascade Glacier and the former Mauna Kea ice cap at short (annual to centennial) and long (millennial and multimillennial) time scales. To quantify the response of South Cascade Glacier to atmospheric conditions, a surface energy...

Lacustrine micro-fossil assemblage in core NP04-KH3, a Kullenberg piston core from the Moba-Kalya Horst region of Lake Tanganyika, East Africa, as a biogeochemical proxy for Late Pleistocene and Early Holocene climate and lake level changes

Creator:: Steinkamp, Matthew J.
Abstract:: The objective of this research is to determine the correlation of lacustrine micro-fossils in Lake Tanganyika to changes in climate and lake levels during the Late Pleistocene and Early Holocene. Lake Tanganyika is the second deepest and one of the oldest lakes in the world. The horst and graben geometry...

Dynamics of the Laurentide Ice Sheet

Creator:: Carlson, Anders Eskil
Abstract:: This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...

Use of sheep in the control of an invasive bunchgrass

Creator:: Scholz, Ryan
Abstract:: Studies were conducted to assess influencing the effectiveness of sheep for grazing control of false brome (Brachypodium sylvaticum) an invasive grass species. Orphan lambs were exposed to false brome via grass extract in their milk and naturally reared lambs were exposed by grazing dense stands of false brome with their...

Evaluation of a weevil infestation in thinned lodgepole pine stands, Lewis and Clark National Forest, Montana

Creator:: Hamel, Dennis R., McGregor, Mark D., and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: An infestation of a defoliating weevil, Magdalis gentilis LeConte, was reported in July by Hank Manning, Judith Ranger District forester, Lewis and Clark National Forest. The infestation occurs in precommercially thinned stands of lodgepole pine, Pinus contorta var./atifblia Engelm. in the Moose Creek drainage. Although damages caused by M. gentilis...

Botanical composition and diet quality of beef cattle grazing at three stocking rates following fuels reduction in mixed conifer forests

Creator:: Clark, Abe A.
Abstract:: An experiment was conducted to evaluate the influence of forest fuels reduction on the diet quality, botanical composition, relative preference, and foraging efficiency of beef cattle grazing at different stocking rates. A split plot factorial design was used, with the whole plots (3 ha) being fuel reduced or no treatment...

Demography and habitat selection of northern spotted owls in post-fire landscapes of southwestern Oregon

Creator:: Clark, Darren A.
Abstract:: Several large wildfires in southwestern Oregon during the summers of 2001 and 2002 provided the opportunity to investigate the impacts of wildfire on northern spotted owls (Strix occidentalis caurina). I used radio-telemetry and demographic surveys to describe demographic performance and habitat selection of spotted owls in the areas burned by...

Phylogeography and population structure of least terns (Sterna antillarum)

Creator:: Draheim, Hope M.
Abstract:: Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....

Lodgepole pine needle cast in the lower Clark Fork River drainage

Creator:: Williams, Ralph E. and United States. Forest Service. Northern Region. State & Private Forestry
Abstract:: The pine needle cast fungus, Lophodermella concolor, caused severe discoloration and subsequent defoliation of lodgepole pine on over 4,000 acres and light defoliation on over 4,500 acres of lodgepole pine in the lower Clark Fork River drainage in 1975. Some trees had lost the last 3 years' growth of needles,...
