Fluctuation History Of Great Salt Lake, Utah, During The Last 13,000 Years, United States, National Aeronautics And Space Administration Jul 1989

Fluctuation History Of Great Salt Lake, Utah, During The Last 13,000 Years, United States, National Aeronautics And Space Administration

Water

Great Salt Lake level fluctuations from 13,000 yr B.P. to the present were interpreted by examination of shoreline geomorphic features, shoreline deposits, archeologic sites, isotopic data, and palynologic data.

After the conclusion of the Bonneville paleolake cycle, between 13,000 and 12,000 yr B.P. the lake regressed to levels low enough to deposit a littoral oxidized red bed stratum and a pelagic Glauber's salt layer. A late Pleistocene lake cycle occurred between 12,000 and 10,000 yr B.P. depositing several beaches, the highest reaching an altitude of about 4250 ft (1295.3 m). The lake regressed after 10,000 yr B.P., only to rise …

Testing Macroevolutionary Hypotheses With Cladistic Analysis: Evidence Against Rectangular Evolution, Cliff A. Lemen, Patricia W. Freeman Jul 1989

Testing Macroevolutionary Hypotheses With Cladistic Analysis: Evidence Against Rectangular Evolution, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

The properties of cladistic data sets from small monophyletic groups (6-1 2 species) are investigated using computer simulations of macroevolution. Two evolutionary models are simulated: gradualism and the punctuated-equilibrium hypothesis. Under the conditions of our simulations these two models of evolution make consistently different predictions about the distribution of autapomorphies among species. When strict stasis is enforced, the punctuated-equilibrium hypothesis predicts that the most expected number of autapomorphies per species will be zero, no matter how many characters are used in the analysis. As the number of characters used in the analysis increases, the distribution of the number of autapomorphies …


Wetlands Mitigation Evaluation Vegetation Studies : Final Report To The City Of Norfolk, Walter I. Priest Iii Jul 1989

Wetlands Mitigation Evaluation Vegetation Studies : Final Report To The City Of Norfolk, Walter I. Priest Iii

Reports

Coastal wetlands in Virginia represent a finite resource which is being
subjected to ever increasing development pressures. As a means of reducing
these losses while accomodating necessary economic development, the policy
of wetlands mitigation through compensation is increasingly being utilized
by both regulatory agencies and developers. This practice generally
involves the grading of an upland area to the appropriate elevation and
planting it with wetlands vegetation to replace a mar sh being lost in
another area.


The technology to plant and grow marsh vegetation for this and other
purposes has been well demonstrated . In as few as two growing …


A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill Jun 1989

A Mark-Recapture Study Of Striped Bass In The James River, Virginia : Annual Report 1988, Joseph G. Loesch, Bruce W. Hill

Reports

EXECUTIVE SUMMARY

1. In the Spring 1988, 2,145 striped bass were tagged in the James River.

2. The mean size of striped bass tagged in 1988 (351.6 mm) was 117.9 mm smaller than mean size in 1987. The difference may be due to different locations and times of tagging.

3. The dominant age group in 1987 was the 1982 year class but in 1988 the dominant age group was the 1984 year class. This difference may also be accounted for by different locations and times of tagging.

4. The exodus of the mature fish out of the river after spawning …

Agenda: Boundaries And Water: Allocation And Use Of A Shared Resource, University Of Colorado Boulder. Natural Resources Law Center

Boundaries and Water: Allocation and Use of a Shared Resource (Summer Conference, June 5-7)

Conference organizers and/or faculty included University of Colorado School of Law professors David H. Getches, Lawrence J. MacDonnell and Charles F. Wilkinson.

Boundaries and Water: Allocation and Use of a Shared Resource is the topic of the Center's annual summer program on water this June. Most of the major rivers in the western United States are shared between two or more states. Often tribal governments play an important role in water allocation and use decisions. International considerations also may be involved in some cases. These interjurisdictional issues extend to groundwater as well as surface water.

This conference will provide the …

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle Jun 1989

Temporal And Spatial Patterns Of Abundance Of Age 0 Threadfin Shad (Dorosoma Petenense) In Overton Arm, Lake Mead, William Lee Pelle

Publications (WR)

Temporal and spatial patterns of age 0 threadfin shad (Dorosoma petenense) abundance and growth, in the Overton Arm of Lake Mead, were examined to evaluate the effects of resource availability on the young fish. This was part of a larger, game fishery enhancement study (Lake Mead Fertilization Project), designed to assess feasability of increasing survivorship of larval/juvenile shad by boosting phosphate levels, thereby increasing algal and zooplankton biomass, during the shad spawning period. Shad are the primary forage base for the striped bass (Morone saxatilis) and black bass (Macropterus salmoides) fisheries. Weekly samples were …
