Late Quaternary Dragon Lizards (Agamidae: Squamata) From Western Australia, Julie Rej May 2017

Late Quaternary Dragon Lizards (Agamidae: Squamata) From Western Australia, Julie Rej

Electronic Theses and Dissertations

Fossil Agamidae from Western Australia have been the subject of limited study. To aid in fossil agamid identification, Hocknull (2002) examined the maxilla and dentary of several extant species from Australia and determined diagnostic characters for various species groups. In the study here, fossil agamids from two localities in Western Australia, Hastings Cave and Horseshoe Cave, were examined, grouped, and identified to the lowest unambiguous taxonomic level. Morphometric analyses were conducted to compare morphotypes, and find additional diagnostic characters. From Hastings Cave there were two maxilla morphotypes and three dentary morphotypes. Based on identifications, taxa present at this locality were ...

Bulletins 4000 -

This report aims to provide a summary of national and international activity in the use of agricultural by-products for the production of bioenergy and biofuels. The summary is primarily an internal report for the Department of Agriculture and Food, Western Australia (DAFWA), but will hopefully be of some value to industry proponents that are interested in pursuing the opportunities provided by what are currently low value agricultural waste products. We outline three processes for obtaining energy from these by-products that may be appropriate for the farming sector in Western Australia (WA).


Outcomes Of A Participatory Approach To Interpretive Planning In The Shark Bay World Heritage Area, Western Australia, Kelly J. Chapman Apr 2014

Outcomes Of A Participatory Approach To Interpretive Planning In The Shark Bay World Heritage Area, Western Australia, Kelly J. Chapman

Kelly Chapman

This thesis examines a participatory approach to interpretive planning, employed in the Shark Bay World Heritage Area, Western Australia. At the project outset relations between the conservation agency responsible for administering World Heritage and the local community were strained, and complicated by a history of conflict over the World Heritage listing and subsequent management of the area. A participatory approach to interpretive planning was adopted in the hope that doing so would achieve the following: improved relations between polarised stakeholder groups, increased community support for the plan and its implementation, and improved access to the variety of knowledge pools within ...

The intense political context was often ...


Light Reductions Drive Macroinvertebrate Changes In Amphibolis Griffithii Seagrass Habitat., Adam Gartner, Paul S. Lavery, Kathryn Mcmahon, Anne Brearley, Helen Barwick Nov 2013

Light Reductions Drive Macroinvertebrate Changes In Amphibolis Griffithii Seagrass Habitat., Adam Gartner, Paul S. Lavery, Kathryn Mcmahon, Anne Brearley, Helen Barwick

Kathryn McMahon

Numerous anthropogenic activities can significantly reduce the amount of light reaching seagrass habitats. Typically these result in morphological and physiological changes to the plant and associated algal epiphytes. However, the flow-on effects to seagrass-dependent fauna induced by these disturbances has yet to be examined. This study investigated the effects of different light reduction intensity (high: ~92% reduction; moderate: ~84% reduction), duration (3, 6 and 9 mo) and timing (post-winter and post-summer) on the density and biomass of macroinvertebrate epifauna within an Amphibolis griffithii seagrass ecosystem (Western Australia). There were generally lower epifauna densities and biomass within shaded seagrass plots. When ...

Report Card On Sustainable Natural Resource Use In Agriculture : Status And Trend In The Agricultural Areas Of The South-West Of Western Australia, Department Of Agriculture And Food, Western Australia

Books & book chapters

This report card summarises our current knowledge of the status and trend in the natural resource base in the agricultural areas of the south-west of Western Australia (WA) and provides a discussion of the implications for agricultural industries.

The condition of our natural resources is a complex interaction of numerous processes. In simple terms however, the performance of the land is driven by three primary factors: climate, land characteristics and land management. The first two factors are largely out of the control of land managers, and in a drying and variable climate, land management practices need to be able to ...


Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey Aug 2013

Audit Of Wa Agricultural Lime Quality 2013, Chris Gazey

Bulletins 4000 -

Applying agricultural lime is the most economical way of ameliorating low soil pH in broadscale agriculture in Western Australia (WA). In WA, agricultural lime is usually limesand from coastal sand dunes, crushed limestone from coastal deposits or crushed dolomitic lime (usually marketed as dolomite) from old lake and inland drainage systems. Other sources are Cretaceous chalk and lake bed marls.

WA agriculture is well serviced by lime suppliers, although the quality of lime varies markedly around the State, and cost does not always reflect quality as measured by neutralising value and fineness. Neutralising value and particle size distribution (fineness) are ...

Native Vegetation In Western Australia Is Actively Involved With Soil Formation, Doug Sawkins, William H. Verboom, John S. Pate Mar 2011

Native Vegetation In Western Australia Is Actively Involved With Soil Formation, Doug Sawkins, William H. Verboom, John S. Pate

Bulletins 4000 -

Many adverse situations in Western Australian agriculture have arisen because in the past we cleared native perennial vegetation below safe ecological limits in order to grow annual crops and pasture. In retrospect, we did not fully understand the functioning of the native ecosystems concerned and thus did not foresee the long-term consequences. Research into the survival techniques of native species provides important lessons for future farming. By understanding the behaviour of plants and soils we can maximise their use in a sustainable way. Knowledge of the water acquisition and storage strategies of native plants in seasonally dry areas may be ...

Bulletins 4000 -

Dairy farmers in Western Australia have a long history of being concerned for the environment in which they live and work, from early involvement with Landcare District Committees through to participating in the various programs run in DairyCatch.

They have planted trees, organised soil testing programs, carried out salinity surveys and, more recently, have signed up for effluent, nutrient and irrigation water management programs. Many of these programs produce benefits both on and off the farm—they can improve the farm environment, increase farm productivity and reduce nutrient losses to surface and ground water. The wider community has supported farmers ...


Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey Jan 2011

Subsurface Compaction A Guide For Wa Farmers And Consultants, Stephen Davies, Alison Lacey

Bulletins 4000 -

For plants to grow in agricultural soils, roots and emerging shoots must be able to force their way through the soil. In soils of high strength, this growth is physically restricted. High strength soils may be due to natural soil characteristics and conditions or develop as a result of agricultural practices and may be in layers or throughout the soil profile.

In agriculture, high strength soils commonly occur as a result of compaction. Compaction of agricultural soils can be in the surface (often caused by stock trampling or rain drop splatter) or in the subsurface (usually in a layer at ...
