Colombia's national parks : an analysis of management problems and perceived values

Creator:: Meganck, Richard Albert
Abstract:: This analysis of Colombia's System of National Park Reservations accomplishes four objectives: 1) The historical development of national parks in Colombia was described; 2) The status, as of August, 1974, of the areas administered by the Colombian Renewable Natural Resources Development Institute (INDERENA) was summarized; 3) An analysis of major...

Ecology of curlleaf mountain-mahogany (Cercocarpus ledifolius Nutt.) in Eastern Oregon and adjacent areas

Creator:: Dealy, J. Edward
Abstract:: Cercocarpus ledifolius (curlleaf mountain- mahogany), a small, hardwood evergreen tree, was studied to provide information on germination and initial seedling growth characteristics, and the species' relationship to its environment.and associated vegetation. Exceptional germination for this species resulted from both a wet cold treatment at 4°C for 170 days (88 percent),...

The Response and Effect of Emergent Coastal Vegetation to Sedimentation and the Distribution of Coastal Vegetation Communities along Environmental Gradients

Creator:: Lemein, Todd
Abstract:: Coastal marsh vegetation is an important component in maintaining marsh stability that is threatened by changes in sedimentation, sea level rise, natural and anthropogenic disturbances, and competition from invasive species. Vegetation has been demonstrated to reduce wave energy, increase sedimentation, and decrease erosion in tidal environments under a range of...

A study of actinide de-excitation through neutron emission from the deuteron induced fission of ²³⁸U

Creator:: Sprunger, Peter Hayden
Abstract:: The process of de-excitation of the actinides is a very important question in both pure and applied science. In this dissertation the process was studied using the neutrons emitted in coincidence with fission induced by the bombardment of ²³⁸U with 14.85 MeV deuterons. Neutrons can be emitted at multiple stages...

The vagal inhibitory reflex in the rat stomach

Creator:: Lock, Albert
Abstract:: Electrical stimulation of the vagus nerves produces an excitatory contraction response in the isolated rat stomach. This contraction response was abolished by atropine to unmask the vagal inhibitory response (VIR) elicited during low frequency vagal stimulation. Babring and Gershon (1967), after working on guinea-pigs and mice, hypothesized that both serotonin...

Intra- and interspecific interference between sweet corn (Zea mays L.) and a living mulch of white clover (Trifolium repens L.)

Creator:: Fischer, Albert J.
Abstract:: Living mulches are vegetative covers that can grow in association with row crops and may prevent soil erosion and suppress weeds. Crop reduction from association with the living mulch is a frequent problem with this cultural practice. The interference between a white clover (Trifolium repens L. "New Zealand") living mulch...

Long term temporal perspectives for the demersal fish assemblages of Georges Bank with implications for management and modeling

Creator:: Overholtz, William Joseph
Abstract:: Questions of assemblage persistence, resiliency arid continuity in time were investigated with data from seasonal bottom trawl surveys conducted by the Northeast Fisheries Center, Woods Hole, Massachusetts, from 1963-1978. Cluster analysis proved to be a useful statistical method for delineating assemblage boundries and corresponding resident demersal fish components from Georges...
