Winter And Summer Sediment Nutrient Exchange Rates In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers Sep 1986

Winter And Summer Sediment Nutrient Exchange Rates In Hillsborough Bay, Florida, City Of Tampa Department Of Sanitary Sewers

Reports

Winter and summer in-situ measurements of sediment oxygen demand (SOD) and nutrient exchange rates (NERs) were taken from sandy and muddy sediments in Hillsborough Bay during 1986. The summer-mud SOD rate of 0.23 g 02/m2/hr was roughly twice the summer-sand, winter-sand and winter-mud SOD rates. In general, nutrient flux rates into the water column were usually greater from mud relative to sand, and during the summer compared to the winter. Reservations in the application of the SOD/NER data and recommendations for future SOD/NER measurements are discussed.


Ecological Assessment, Classification And Management Of Tampa Bay Tidal Creeks, Tampa Bay Regional Planning Council (Tbrpc) Sep 1986

Ecological Assessment, Classification And Management Of Tampa Bay Tidal Creeks, Tampa Bay Regional Planning Council (Tbrpc)

Reports

The final product is a detailed restoration and management plan for three minor tributaries in the Tampa Bay watershed and one general application. It is the intent of the Council to implement all elements of the four plans wherever feasible during Developments of Regional Impact (DRI's) and Intergovernmental Coordination and Review (IC&R) reviews and through coordinat.ion with the DNR gill-net license fee habitat restoration program, as well as local government initiatives. The efforts of the Council's Agency on Bay Management will also be critical in implementing the findings and recommendations of this project.

External Development Affecting the National Parks: Preserving "The Best Idea We Ever Had" (September 14-16)

Conference organizers and/or faculty included University of Colorado School of Law professors Lawrence J. MacDonnell and Daniel Magraw.

The conference will be held at the Aspen Lodge, adjacent to Rocky Mountain National Park near Estes Park, Colorado.

It was Wallace Stegner who called the national parks "the best idea we ever had." The continuing increases in usage attest to their popularity. National parks are created to preserve areas of special scenic and cultural value for enjoyment and use. Managing the parks in a manner that protects the important values and purposes for which they were created presents important and difficult …


Preliminary Study Of The Seagrasses In Middle Tampa Bay Between Apollo Beach And Simmons Park, Mangrove Systems, Inc. Sep 1986

Preliminary Study Of The Seagrasses In Middle Tampa Bay Between Apollo Beach And Simmons Park, Mangrove Systems, Inc.

Reports

Comparison of recent (1986) and earlier (1983) aerial photography indicated that an apparent recovery of seagrasses was occurring on the subtidal shelf north of Simmons Park (Ruskin) and south of Apollo Beach, in Middle Tampa Bay (Fig. 1). This was suggested by the numerous circular patches of grass observed on the offshore portions of the shelf. This observation provided the incentive to undertake a preliminary assessment of seagrass species composition, percent cover, and shoot density along transects in this area. This study was a cooperative effort between the Bay Study Program (City of Tampa) and Mangrove Systems, Inc.


Interference Competition In A Heteromyid Community In The Great Basin Of Nevada, Usa, Cliff A. Lemen, Patricia W. Freeman Sep 1986

Interference Competition In A Heteromyid Community In The Great Basin Of Nevada, Usa, Cliff A. Lemen, Patricia W. Freeman

School of Natural Resources: Faculty Publications

Removal experiments with three species of heteromyid rodents were performed during two summers in the Great Basin of Nevada, USA. These experiments were designed to determine the importance of interference competition in these species by quantifying the short-term responses to the removal of one or more of the species. Our results indicate that the removal of a large species (Dipodomys merriami) does have a positive effect on a smaller species with a similar diet (Perognathus longimembris). These results and others presented are consistent with a hypothesis of interference competition. However, while there is short-term increase in …

Cliff-Height And Slope-Angle Relationships In A Chronosequence Of Quaternary Marine Terraces, San Clemente Island, California, Russell Crittenden, Daniel R. Muhs

United States Geological Survey: Staff Publications

Zusammenfassung. Eine Abfolge quartarer Strandterrassen auf ~an Clemente Island, Kalifornien, liefert einen Rahmen fur die quantitative Analyse der Anderungen an vom Meer verlassenen Kustenkliffen als Funktion der Zeit. Es wurde eine Abschatzung der Anwendbarkeit von BUCKNAM & ANDERSON (1979) log-lin~arer Beziehung zwischen Wandhohe und Hangwinkel durchgefuhrt, indem Brandungskliffhohe und maximale Hangwinkel verwendet wurden. Die Ergebnisse zeigen eine regelhafte Zunahme des Hangwinkels mit dem Logarithmus der Kliffhohe, und Kliffe einer bestimmten Hohe zeigen m,it der Zeit eine Abnahmedes maximalen Hangwinkels. 1m ganzen waren die Relationen schwacher als fur FluBterrassen und Bruchstufen in unverfestigten Materialen, aber die Methode kann wahrscheinlich verwendet werden, …
