Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D. Sep 1989

Tidal Flat Ecology: An Experimental Approach To Species Interactions By K. Riess, John T. Tanacredi Ph.D.

Faculty Works: CERCOM

A periodic pause to intensely observe a singularly unique ecosystem sharpens one's awareness of this diverse world of ours, especially, as the author notes, if one observes a transitional ecosystem whose ecological treasures are hidden or maybe obscured by a tidal sediment's resemblance to a large, rotten cheese! "It smells, is slimy and sticky, is punched with holes and crowded with various worms." Sounds good to me! Reise's "pause" encompasses 10 years in which he investigated the Wadden Sea mudflats near the border between West Germany and Denmark. He uses this site to discuss the biotic and abiotic interactions within …

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 …


Management Of The South-West Inshore Trawl Fishery., N. Moore Feb 1989

Management Of The South-West Inshore Trawl Fishery., N. Moore

Fisheries management papers

This report outlines the management plan for the south west inshore trawl fishery which already operates in coastal waters less than 200 metres deep between Guilderton and Cape Leeuwin. This management plan takes into account these important concerns and has specifically set aside a strip of coastal area from Cape Bouvard to Cape Leeuwin for recreational usage and for protection of the benthic community, and closed the management zone north of Burns Beach to trawling.

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon Jan 1989

Planning For Horticultural Expansion On The Swan Coastal Plain, P Coghlan, Geoff Moore, Jim Dixon

Journal of the Department of Agriculture, Western Australia, Series 4

Horticulture is an intensive, high value form of agriculture highly dependant on the availability of good water supplies for the year-round production of fresh produce. Production increase in Western Australia and the encouragement and development of export markets has caused rapid expansion if the industry in recent years.

Expansion is expected to continue, placing severe pressure on available water supplies and suitable land close to markets. At present' 90 per cent of the Stase's horticultural land is on the Swan Coastal Plain and minor selected hills areas around Perth.


Irrigation And Fertilizer Management For Horticultural Crops On The Swan Coastal Plain, I R. Mcpharlin, Greg Luke Jan 1989

Irrigation And Fertilizer Management For Horticultural Crops On The Swan Coastal Plain, I R. Mcpharlin, Greg Luke

Journal of the Department of Agriculture, Western Australia, Series 4

The Swan Coastal Plain is an important area for the production of vegetables, flowers and fruits in Western Australia. The yellow Cottesloe, Karrakatta and the white-grey Bassendean Sands upon which most of this production is based are infertile in their natural state and require large inputs of fertilizer for succesful production of horticultural crops.

Improved irrigation and fertilizer management will be needed to reduce nutrient leaching from horticultural crops on the coastal plain. This will probably involve applying fertilizer and water more frequently, but in smaller quantaties thaan currently practiced. The result should more closely match water and fertilizer supply …


Improved Fertilizing Practices On The Peel-Harvey Catchment, P T. Arkell Jan 1989

Improved Fertilizing Practices On The Peel-Harvey Catchment, P T. Arkell

Journal of the Department of Agriculture, Western Australia, Series 4

Broad-acre farmers in the Peel-Harvey catchment have met a challange and achieved a great deal since the fertilizer extension programme started in 1983.

The main objective of the extension programme has been to ensure that every year three-quarters of the farmers make economically and technically sound fertilizer decisions, thus causing a minimum amount of phosphorus to enter the waterways of the Peel-Harvey estuarine system.


Riparian Plant Water Relations Along The North Fork Of The Kings River, California, J. L. Nachlinger, S. D. Smith, R. J. Risser Jan 1989

Riparian Plant Water Relations Along The North Fork Of The Kings River, California, J. L. Nachlinger, S. D. Smith, R. J. Risser

Life Sciences Faculty Research

Plant water relations of five obligate ripar-ian species were studied along California's North Fork Kings River. Diurnal stomatal conductance, transpi-ration, and xylem pressure potentials were measured throughout the 1986 growing season and in mid-season in 1987. Patterns were similar for all species although absolute values varied considerably. Maximum stomatal conductance occurred early in the day and season during favorable environmental conditions and decreased as air temperature and the vapor pressure difference between the leaf and air increased. Maximum transpiration rates occurred in mid-morning and mid-summer resulting in estimated daily water losses per unit sunlit leaf area of 163-328 mol H2O …

Executive Summary

Biological diversity refers to the variety and variability among living organisms and the ecological complexes in which they occur. Diversity can be defined as the number of different items and their relative frequency. For biological diversity, these items are organized at many levels, ranging from complete ecosystems to the chemical structures that are the molecular basis of heredity. Thus, the term encompasses different ecosystems, species, genes, and their relative abundance (OTA, 1987).

There is an ongoing, unprecedented loss of the variety as well as absolute numbers of organisms-from the smallest microorganism to the largest and most spectacular of …
