A Molecular Framework Phylogeny For Ptilotus (Amaranthaceae), Timothy A. Hammer Oct 2014

A Molecular Framework Phylogeny For Ptilotus (Amaranthaceae), Timothy A. Hammer

Biological Sciences Theses & Dissertations

Ptilotus (Amaranthaceae) is an Australian genus with over 100 species, most of which occur in arid Western Australia. Ptilotus has been a taxonomically difficult genus; despite rigorous morphological studies into the genus over many years, previous workers have found it difficult to delimit infrageneric groups due to inconsistent morphological variation. With the goal to establish a phylogenetic framework for the genus, 100 taxa were sampled, including 87 Ptilotus spp., and the ITS nrDNA and matK cpDNA were sequenced. The phylogeny was reconstructed using Bayesian, maximum likelihood and maximum parsimony analyses on separate and concatenated datasets. Morphological characters were assessed and …

Biomass Scoping Study: Opportunities For Agriculture In Western Australia, Kim Brooksbank, Mitchell Lever, Harriet Paterson, Melissa Weybury

Bulletins 4000 -

This 2014 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).

Glyphosate Resistant Weeds - Beat Them Before They Beat You, Sally Peltzer Jan 2014

Glyphosate Resistant Weeds - Beat Them Before They Beat You, Sally Peltzer

Grain and other field crops published reports

Herbicide resistance develops if the weeds exist in the population and set fertile seed. Being vigilant, keeping weed populations low and stopping seed set is the best way to prevent glyphosate resistance development:

  • know the herbicide use history of each paddock. If glyphosate has been the dominant knockdown and spray-topping product used, it's time to change
  • conduct herbicide resistance testing to determine what herbicides are effective on key weeds
  • aim for maximum control
  • establish a more diverse rotation to increase the number of control tactics available
  • use non-herbicide control tactics at every opportunity
  • always monitor the success of each control …

The overall aim of this study was to explore the systematics and biogeographic patterns of the freshwater crayfish genus Engaewa Riek, a strongly burrowing freshwater crayfish restricted to the coastal corner of south-western Australia (SWA). The genus Engaewa is a Gondwanan relict with great potential as a marker of historical processes, due to its high habitat specificity and low dispersal ability. This study comprises an extensive taxonomic and phylogenetic revision of the genus Engaewa (using both molecular and morphological data), a detailed study of its distribution and uses the knowledge gained to explore biogeographic patterns in the biodiversity hotspot of …


Fate Of Eucalyptus Marginata Seed From Canopy-Store To Emergence In The Northern Jarrah Forests Of Western Australia: Research To Help Improve Regeneration Following Shelterwood Treatment, Jeffrey Cargill Jan 2014

Fate Of Eucalyptus Marginata Seed From Canopy-Store To Emergence In The Northern Jarrah Forests Of Western Australia: Research To Help Improve Regeneration Following Shelterwood Treatment, Jeffrey Cargill

Theses: Doctorates and Masters

The establishment of seedling regeneration is a key process in and indicator of ecologically sustainable forest management. The availability of seed and the creation of a suitable seedbed are recognised as important factors limiting seedling recruitment. A silvicultural method commonly used across northern and eastern jarrah forest blocks is shelterwood cutting. The primary objective of treating jarrah forest to shelterwood is to promote seedling regeneration in areas lacking sufficient advanced growth. Despite the widespread and progressive implementation of the shelterwood method, its application in jarrah forest has shown varying degrees of success.

This thesis sought to investigate and better understand …

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 …

Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia. Jul 2013

Policy On Restocking And Stock Enhancement In Western Australia, Department Of Fisheries Western Australia.

Fisheries Management Papers

The practice of releasing hatchery-reared fish into existing populations to augment fishing (stock enhancement) or restore depleted spawning biomass (restocking) has occurred around the world for decades with varying degrees of success. The underpinning concept is to produce and release fish into wild populations to increase their abundance, catch rates and/or fishery yields

If restocking and stock enhancement activities are to be successful, they should have clear objectives and be well planned and targeted at situations where there is a reasonable expectation of having a beneficial effect.

Release Of Dissolved Organic Carbon From Seagrass Wrack And Its Implications For Trophic Connectivity, Paul S. Lavery, Kathryn M. Mcmahon, Julia Weyers, Mary C. Boyce, Carolyn Elizabeth Oldham Jan 2013

Release Of Dissolved Organic Carbon From Seagrass Wrack And Its Implications For Trophic Connectivity, Paul S. Lavery, Kathryn M. Mcmahon, Julia Weyers, Mary C. Boyce, Carolyn Elizabeth Oldham

Research outputs 2013

The export of old leaves and stems (wrack) from seagrass meadows provides a mechanism for trophic connectivity among coastal ecosystems. As little of this wrack is consumed by mesograzers, leached dissolved organic carbon (DOC) may determine the importance of wrack as a trophic subsidy. However, few studies have examined the effect of seagrass type or age on the release of DOC or its bioavailability. We examined the amount and composition of DOC released from different wrack: Posidonia sinuosa, Amphibolis antarctica and the alga Laurencia sp. We then examined the effect of age on DOC leaching from P. sinuosa wrack. The …

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia Oct 2012

A Review Of The Management Arrangements And Licensing Framework For The Aquatic Tour Industry In Western Australia. Discussion Paper On Management And Licensing Options For The Aquatic Tour Industry., Department Of Fisheries Western Australia

Fisheries Management Papers

The Department of Fisheries (Department) is proposing a new simplified management approach which focuses on fishing as the core criteria in the new licensing framework. Given the low level of impact of aquatic eco-tours and shore-based fishing, consideration is being given to removing the need for these activities to be formally licensed. The Department is of the view that these activities can be adequately managed by regulations that have broader application across the community.

The current management, licensing and fee structures are complex and provide limited business flexibility. A simplified management approach will also improve the Department’s capacity to monitor …
