Agenda: New Sources Of Water For Energy Development And Growth: Interbasin Transfers: A Short Course, University Of Colorado Boulder. Natural Resources Law Center

New Sources of Water for Energy Development and Growth: Interbasin Transfers: A Short Course (Summer Conference, June 7-10)

Even before the [Natural Resources Law] Center was established [in the fall of 1981], the [University of Colorado] School of Law was organizing annual natural resources law summer short courses. To date four programs have been presented:

- July 1980: "Federal Lands, Laws and Policies-and the Development of Natural Resources"

- June 1981: "Water Resources Allocation: Laws and Emerging Issues"

- June 1982: "New Sources of Water for Energy Development and Growth: lnterbasin Transfers"

- June 1983: "Groundwater: Allocation; Development and Pollution"

(Reprinted from Resource Law Notes, no. 1, Jan. 1984, at 1.)

Faculty for this conference included University of Colorado School of Law ...

Introduced Species And The Issue Of Animal Welfare, Michael Hutchins, Victoria Stevens, Natasha Atkins Jan 1982

Introduced Species And The Issue Of Animal Welfare, Michael Hutchins, Victoria Stevens, Natasha Atkins

Ecology Collection

Recently, considerable debate has been heard about the control or elimination of introduced or "exotic" animals on publicly held U.S. lands. Species introductions, whether intentional or unintentional, seem to be an inevitable result of human activities, but they may result in both economic and ecological problems: It has been estimated that over 90 percent of all such introductions have been harmful in some respect. Control of exotics can be accomplished through containment, shooting, poisoning, reintroduction of native predators, introduction of disease organisms, live capture and removal, and reproductive inhibition.

Those who must make decisions about the fate of introduced ...


An Evaluation Of Nutrient Sources To Onslow Bay, North Carolina, Larry P. Atkinson, Leonard J. Pietrafesa, Eileen E. Hofmann Jan 1982

An Evaluation Of Nutrient Sources To Onslow Bay, North Carolina, Larry P. Atkinson, Leonard J. Pietrafesa, Eileen E. Hofmann

CCPO Publications

Hydrographic and current meter data from Onslow Bay, North Carolina, were examined to determine the relative importance of various nutrient sources.

Upwelled Gulf Stream water is the major source of nutrients while rivers represent a minor, if not insignificant, source. In the summer during stratified conditions, the upwelled water penetrates across the shelf, but in the winter the upwelled water is restricted to the outer shelf. Nitrate flux across the 40 m isobath was calculated from continuous temperature and current records. Flux during the summer of 1976 was 2 μM m2 sec-1 which is considerably less than flux ...


The Floodplain Vegetation Of The Platte River: Phytosociology, Forest Development, And Seedling Establishment , Paul Jon Currier Jan 1982

The Floodplain Vegetation Of The Platte River: Phytosociology, Forest Development, And Seedling Establishment , Paul Jon Currier

Retrospective Theses and Dissertations

A vegetation inventory was conducted along 200 miles of the North Platte and Platte rivers in Nebraska. Twelve major vegetation types were identified using Twinspan, a computerized reciprocal averaging ordination technique. Herbaceous communities included annual and perennial mudflats, marshes, lowland grasslands, and upland grasslands. Lowland shrub communities were dominated by Salix exigua and Amorpha fruticosa, and upland shrub communities were characterised by Amorpha and Cornus drummondii. Populus-Salix and Populus-Elaeagnus forests dominated on wetland sites, while Populus-meadow Populus-Juniperus, and mixed hardwood forests dominated on moderately dry sites;Trees on the Platte River floodplain primarily established following the 70% decline in mean ...
