Claw Morphometrics In Monitor Lizards: Variable Substrate And Habitat Use Correlate To Shape Diversity Within A Predator Guild, Domenic D'Amore, Simon Clulow, J. Sean Doody, David Rhind, Colin R. Mchenry Jul 2018

Claw Morphometrics In Monitor Lizards: Variable Substrate And Habitat Use Correlate To Shape Diversity Within A Predator Guild, Domenic D'Amore, Simon Clulow, J. Sean Doody, David Rhind, Colin R. Mchenry

Faculty Articles

Numerous studies investigate morphology in the context of habitat, and lizards have received particular attention. Substrate usage is often reflected in the morphology of characters associated with locomotion, and, as a result, claws have become well‐studied ecomorphological traits linking the two. The Kimberley predator guild of Western Australia consists of 10 sympatric varanid species. The purpose of this study was to quantify claw size and shape in the guild using geometric morphometrics, and determine whether these features correlated with substrate use and habitat. Each species was assigned a Habitat/substrate group based on the substrate their claws interact with ...

ECU Publications Post 2013

Heat waves have profoundly impacted biota globally over the past decade, especially where their ecological impacts are rapid, diverse, and broad-scale. Although usually considered in isolation for either terrestrial or marine ecosystems, heat waves can straddle ecosystems of both types at subcontinental scales, potentially impacting larger areas and taxonomic breadth than previously envisioned. Using climatic and multi-species demographic data collected in Western Australia, we show that a massive heat wave event straddling terrestrial and maritime ecosystems triggered abrupt, synchronous, and multi-trophic ecological disruptions, including mortality, demographic shifts and altered species distributions. Tree die-off and coral bleaching occurred concurrently in response ...


Increasing Dietary Breadth Through Allometry: Bite Forces In Sympatric Australian Skinks, Domenic D'Amore, David Meadows, Simon Clulow, Jeremiah Sean Doody, David Rhind, Colin Mchenry Jan 2018

Increasing Dietary Breadth Through Allometry: Bite Forces In Sympatric Australian Skinks, Domenic D'Amore, David Meadows, Simon Clulow, Jeremiah Sean Doody, David Rhind, Colin Mchenry

Faculty Articles

Ecomechanical measures of performance such as bite force may function as an indirect measure of niche. This study proposes that allometric changes in performance may contribute to niche separation, especially in a group where the specific mechanism(s) remains unclear. We surveyed the bite force and morphology of 5 wild caught, sympatric skink species in the Kimberley region of Western Australia. Skinks were collected from trapline fences, weighed, photographed, and maximum bite force was measured with a piezoresistive force sensor. Morphological metrics were derived from photographs of the dorsum. Normalized morphological traits indicate interspecific variability in form, particularly in forelimb ...

Sedimentology Of Acid Saline Lakes In Southern Western Australia: Newly Described Processes And Products Of An Extreme Environment, Kathleen Counter Benison, Brenda Beitler Bowen, Francisca Oboh-Ikuenobe, Elliot A. Jagniecki, Deidre A. Laclair, Stacy L. Story, Melanie R. Mormile, Boyoung Hong

Francisca Oboh-Ikuenobe

Naturally acid saline systems with pH values between 1.7 and 4 are common on the Yilgarn Craton of southern Western Australia. a combination of physical and chemical processes here yield a previously undescribed type of modern sedimentary environment. Flooding, evapoconcentration, desiccation, and eolian transport at the surface, as well as influx of acid saline groundwaters, strongly influence these lakes. Halite, gypsum, kaolinite, and iron oxides precipitate from acid hypersaline lake waters. Shallow acid saline groundwaters affect the sediments of the lakes and associated mudflats, sandflats, channels, and dunes by precipitating early diagenetic halite, gypsum, iron oxides, clays, jarosite, and ...

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 ...

Impact Of Consumer Copayments For Subsidised Medicines On Health Services Use And Outcomes: A Protocol Using Linked Administrative Data From Western Australia, K Seaman, F Sanfilippo, E Roughead, M Bulsara, A Kemp-Casey, C Bulsara, G Watts, D Preen Jan 2017

Impact Of Consumer Copayments For Subsidised Medicines On Health Services Use And Outcomes: A Protocol Using Linked Administrative Data From Western Australia, K Seaman, F Sanfilippo, E Roughead, M Bulsara, A Kemp-Casey, C Bulsara, G Watts, D Preen

Health Sciences Papers and Journal Articles

Introduction: Across the world, health systems are adopting approaches to manage rising healthcare costs. One common strategy is a medication copayments scheme where consumers make a contribution (copayment) towards the cost of their dispensed medicines, with remaining costs subsidised by the health insurance service, which in Australia is the Federal Government. In Australia, copayments have tended to increase in proportion to inflation, but in January 2005, the copayment increased substantially more than inflation. Results from aggregated dispensing data showed that this increase led to a significant decrease in the use of several medicines. The aim of this study is to ...

A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler Sep 2016

A Pilot Study Of Sheep Disease Surveillance In Western Australia, Roy Butler

Contributions to Conferences

A pilot study of sheep disease surveillance was conducted in 2014-2015 on four farms in the eastern wheatbelt of Western Australia. The participants observed their sheep, sufficiently closely to notice disease, at least every second day. Most of the disease syndrome reports related to fewer than five sheep, demonstrating that farmers noticed problems in individual sheep, and not only in groups of sheep. Of a total of 66 disease syndrome observations reported over 12 months, the three most frequently occurring syndromes were found dead + sudden death (combined), skin lesions, and lameness.

Propagating Jujubes, Rachelle Johnstone Jan 2016

Propagating Jujubes, Rachelle Johnstone

Research Reports

Jujubes can be propagated by various methods such as wedge/cleft grafting, whip grafting and bark grafting as well as budding. Local propagators have better success with budding but find that wedge grafting leads to a stronger tree. Most of the latest research into propagation is in micropropagation and tissue culture however this technique is mainly used for research and breeding new cultivars and not in a commercial capacity. Grafting can be more of an art than a science. Much of the success of grafting depends on not only performing a technically correct graft but performing the graft at the ...

Bulletins

The better fertiliser decisions for cropping project (BFDC) (2009-2012) was completed to provide comprehensive information to improve fertiliser decisions for the cropping industry in Australia (Speirs et al. 2013a). The WA component provides interpretation of results from crop nutrient application experiments for the WA cropping system, and developed a tool for estimating nutrient losses from cropping systems soils.

The BFDC-WA project aims to use the 4R principles by producing a series of bulletins on nutrient management for the cropping system of WA.


Ecology Of Feral Cats Felis Catus And Their Prey In Relation To Shrubland Fire Regimes, Tim S. Doherty Jan 2015

Ecology Of Feral Cats Felis Catus And Their Prey In Relation To Shrubland Fire Regimes, Tim S. Doherty

Theses: Doctorates and Masters

Invasive predators are major drivers of global biodiversity loss and their impacts may be worsened by other disturbances such as fire. I examined how the fire history of shrublands influences the ecology of feral cats Felis catus, dingoes Canis dingo and their prey species in Western Australia’s northern Wheatbelt region.

A review of the literature revealed that feral cats inhabit a diverse range of ecosystems worldwide, but are generally recorded most often in habitat types characterised by a mixture of plant growth forms close to ground level. Cat habitat use is influenced by predation/competition, prey availability, shelter availability ...

Despite the increasing use of dietary patterns (DP) to study diet and health outcomes, relatively few studies have examined the reliability of DP using different dietary assessment methods. Reduced-rank regression (RRR) is an emerging statistical method that incorporates a priori information to characterise DP related to specific outcomes of interest. The aim of the present study was to compare DP identified using the RRR method in a FFQ with those in a 3 d food record (FR). Participants were 783 adolescents from the Western Australian Pregnancy (Raine) Cohort Study who completed both a FFQ and FR at 14 years 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

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 ...

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

ECU Publications 2013

ABSTRACT: 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 ...
