Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin Jan 1990

Bulletin No 4168 - Plants In Australia Which When Eaten Produce Photosensitization In Livestock, T E H Aplin

Bulletins 4000 -

Photosensitization is the term used to describe inflammation of the skin (usually unpigmented) caused by photodynamic compounds, circulating in blood stream, becoming bound to dermal cells and fluorescing when the animal is exposed to ultraviolet light (290-400 nm).

Photosensitization usually occurs when an animal eats certain plants that contain photodynamic compounds. These compounds can be deposited unchanged in the skin after ingestion, the normal liver being incapable of excreting the native fluorescent compound. This is termed type 1 photosensitization and the compounds involved are naphthodianthrone derivatives. Photodynamic compounds can also be produced through aberrant metabolism by the liver due to …

Plantscan, Ted Lefroy, Fritz Droge

Natural resources published reports

PLANTSCAN is a network of schools and landholders throughout the wheatbelt of Western Australia. It aims to speed up the process of testing plants for their suitability to this environment.

This kit contains seed of various trees and shrubs and notes on how to grow them, plant them out into a small plot and record their progress.

Schools and landholders throughout the wheatbelt who have purchased this kit become part of a research network aimed at selecting plants that will:

* overcome soil erosion;

* overcome soil salinity;

* and provide a source of income for farmers.

The following sheets …


Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder Jan 1990

Salinity And Waterlogging On The Esperance Downs Research Station, D J. Mcfarlane, A T. Ryder

Resource management technical reports

Details the situation on the station so that the demonstration and research programs can be designed and the effect of the treatments assessed. Past work on the station has been briefly summarised and the results of geophysical surveys and additional drilling are given. Surveys of electromagnetic terrain conductivities have shown where salinity is most serious at present. The most deeply penetrating method may have identified areas likely to developing salinity in future.


Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry Jan 1990

Spacing Water Points In The Southern Pastoral Areas Of Western Australia, Don Burnside, Adrian Williams, Peter Curry

Bulletins 4000 -

An inadequate distribution of watering points in our pastoral lands, particularly in the saltbush/bluebush pasture, has caused localisized land degradation close to waters and reduced animal productivity (particularly in stressful times). From experimentation and observation, some generalised recommendations for water supply distribution in pastoral areas can be made.

Experimental Summaries - Plant Research

Trial 90C49

Grass and broad leaved weed control in direct sown crops.

Location: Chapman Valley Research Station.

The low rate of sprayseed with diuron was not as effective on the grasses. It may indicate some antagonism within the mix as the same rate of sprayseed with metribuzin did not cause any drop in grass control. The addition of 2, 4-D amine may have boosted the mixes activity on capeweed as the sprayseed metribuzin mix was not very good on capeweed.

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke Oct 1989

Fisheries Report No 82 - Effects Of Fish Trapping On The Shark Bay Snapper Fishery, M. J. Moran, J. Jenke

Fisheries Research Reports

Traps have been a controversial method of catching pink snapper Chrysophrys auratus (Sparidae) around Shark Bay, Western Australia, since 1959. The history of the issue and the relevant regulations are reviewed; and results of in­vestigations into specific concerns about trap fishing are reported. Concerns of ghost-fishing by lost traps have been largely allayed by underwater TV film of snapper escaping from a standard snapper trap.

A major concern was that traps might physically damage the benthic fauna, e.g. corals. A TV survey showed that while fragile hard corals are abundant in shallower water nearby, the deeper snapper grounds themselves are …

NMRS (165 ha) was leased from "Daisy Downs" (Manager Mr Ken Thompson) in 1985. NMRS was established in response to famer and local goverment demand for more research on the shallow, heavy soils in a low rainfall area. It is run along similar lines to the East Chapman Research Station (ECRS), with large rotation paddocks (42 ha) set up to study farming systems the remainder of the leased area being used for general experimental purposes.
