Common Conservation Works Used In Western Australia, M G. Keen

Resource management technical reports

This booklet is presented to assist proponents and planners of conservation works by describing the common types used in Western Australia. For each common type, design criteria are listed along with the variables affecting increased risks associated with degradation or structural failure. This information will be useful in choosing appropriate conservation works to alleviate specific degradation in a safe manner.

Neurological Effects On Startle Response And Escape From Predation By Medaka Exposed To Organic Chemicals, Steven P. Bradbury, Richard W. Carlson, Robert A. Drummond, Dean E. Hammermeister

Steven P. Bradbury

Simultaneous electrophysiological and behavioral studies were performed on 21–32 day old juvenile medaka (Oryzias latipes) exposed at sublethal concentrations to organic chemicals representing various modes of action. Non-invasive recordings were made of the electrical impulses generated within giant neuronal Mauthner cells, associated interneurons and motoneurons, and axial musculature, all of which initiate the startle or ‘escape’ response in fish. Timing in ms between these electrical sequelae was measured for each fish before and after 24 and 48 h exposure to a chemical. Carbaryl and phenol affected Mauthner cell to motoneuron transmission while chlorpyrifos, carbaryl, phenol and 2,4-dinitrophenol (DNP) showed neuromuscular …

Ecological Evaluation For The West Ash Creek Potential Research Natural Area, Pine Ridge Ranger Unit, Nebraska National Forest, Steven B. Rolfsmeier

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

The West Ash Creek Potential Research Natural Area is located within pastures 6, 7, and 11 of the Pine Ridge Unit of the Nebraska National Forest ca 18 mi. (30 km) southwest of Chadron, Nebraska. The area consists of ca 1020 acres of mostly successional pine forest burned in a 1985 wildfire, with unburned forest, some grassland, and riparian canyon bottoms. The area is within the Pine Ridge ecosystem of the White River watershed in northwestern Nebraska. The area has remained ungrazed nearly continuously since 1986.

This document was prepared to provide the Forest Service with information to determine the …

Results Of Investigations Into The Groundwater Response And Productivity Of High Water Use Agricultural Systems 1990-1997. 2. Souths' Catchment (Darkan), A D. Smith, Richard J. George Dr, P R. Scott, D L. Bennett, R J. Rippon, G J. Orr

Resource management technical reports

High water use vegetation systems for salinity control were trialed on a 90 ha catchment located 12 km north north-west of Darkan, Western Australia. The catchment receives about 560 mm annual rainfall and 1895 mm annual evaporation. The catchment is characterised by a number of actively expanding seeps which are developing under the strong geological control of quartz and dolerite dykes. Development of salinity is also influenced by high recharge rates in the free draining gravel soils of the upper slope.
