Limitations On Inferring Shark Vulnerability From Spatial Habitat Protection. Response To Shark Conservation Hindered By Lack Of Habitat Protection, Matias Braccini, Stephen J. Newman

Fisheries Research Articles

Birkmanis et al. (2020a) used occurrence data obtained from commercial fisheries to infer the suitable habitat for eight shark species within the Exclusive Economic Zone (EEZ) of Australia, and quantify the amount of suitable habitat contained within existing no-fishing Marine Protected Areas (MPAs). The authors state that shark conservation is hindered because suitable habitat is mostly unprotected from commercial fishing, therefore increasing the vulnerability of the assessed species. In doing so, the authors imply that shark conservation depends predominantly on establishing MPAs in highly suitable habitats; this, unfortunately, would disregard the broad range of other measures available in the fisheries …

Monitoring Groundwater, Department Of Primary Industries And Regional Development, Western Australia

Natural resources factsheets

Rising groundwater is a major land degradation hazard in many areas of the South West Agricultural Region of Western Australia, and results in increased salinisation. Collecting data on the depth to groundwater and water quality over time is the only way to know whether the watertable is rising, falling or static, if water quality is changing, and the degree of salinity risk.

The Department of Primary Industries and Regional Development recommends that groundwater monitoring is part of a whole farm, and preferably whole catchment, plan.

Water Quality Study Of The Muchea Livestock Truck Wash, Simon Clarendon, David Weaver, Justin L.M Hardy, Claire Coffey, Robert Summers, David Rogers, Peta Richards

Resource management technical reports

Across Australia there is a lack of information on the quality of the water discharged from facilities that are used to wash livestock trucks. This water quality scoping study partially fills that information gap and provides a starting point for future planning, design and construction of livestock truck washes.

The study was undertaken in 2011–12 at the Western Australian Muchea Livestock Centre, and aimed to gain insights into water quality associated with the truck wash facility at that site. These insights can help to inform the planning for further construction of truck wash facilities throughout the state, and whether disposing …

Plant Diseases Impacting Oaten Hay Production In Australia - A Review, Kylie Chambers, Geoff J. Thomas

Bulletins 4000 -

In Australia, there are a range of fungal, bacterial and viral pathogens that infect oats, impacting on yield and quality of grain and hay crops. The overall impact of these diseases on oaten hay production is not well researched or understood, especially compared to that of other cereal crops. Export hay is evaluated on physical qualities such as stem thickness and greenness and nutritional qualities including water-soluble carbohydrates, neutral detergent fibre, acid detergent fibre and dry matter digestibility. The colour/ greenness of oaten hay can be reduced by disease lesions, chlorosis and saphrophytic fungi growing on dead tissue all of …

The First Genetic Map For A Psoraleoid Legume (Bituminaria Bituminosa) Reveals Highly Conserved Synteny With Phaseoloid Legumes, Matthew N. Nelson, Jafar S. Jabbari, Rust Turakulov, Aneeta Pradhan, Maria Pazos-Navarro, Jacob S. Stai, Steven B. Cannon, D. Real

Grain and Other Field Crops Research Articles

We present the first genetic map of tedera (Bituminaria bituminosa (L.) C.H. Stirton), a drought-tolerant forage legume from the Canary Islands with useful pharmaceutical properties. It is also the first genetic map for any species in the tribe Psoraleeae (Fabaceae). The map comprises 2042 genotyping-by-sequencing (GBS) markers distributed across 10 linkage groups, consistent with the haploid chromosome count for this species (n = 10). Sequence tags from the markers were used to find homologous matches in the genome sequences of the closely related species in the Phaseoleae tribe: soybean, common bean, and cowpea. No tedera linkage groups align in their …

Sulfate Sorption Measured By A Buffering Index Over A Range Of Properties Of Soils From South Western Australia, Geoff Anderson

Natural Resources Research Articles

Sulfate sorption by the soil affects the rate of sulfate leaching, which impacts on the availability of soil sulfate for plant uptake. In Australia, plant-available sulfur is measured using 0.25 M KCl heated for 3 h at 40°C to extract soil sulfur (SKCl40). This paper describes a technique referred to as a sulfate buffering index (SBI), which provides a measurement of sulfate sorption. SBI when combined with the estimates of the q and b parameters of the Freundlich equation, can be used to define a sorption curve. The equation is S = acb – q; where S is the …

Noodles Made From High Amylose Wheat Flour Attenuate Postprandial Glycaemia In Healthy Adults, Kim Ang, Carla Bourgy, Haelee Fenton, Ahmed Regina, Marcus Newberry, Dean A. Diepeveen, Domenico Lafiandra, Sara Grafenauer, Wendy Hunt, Vicky Solah

Grain and Other Field Crops Research Articles

Previous research has not considered the effect of high amylose wheat noodles on postprandial glycaemia. The aim of the study is to investigate the effect of consumption of high amylose noodles on postprandial glycaemia over 2-h periods by monitoring changes in blood glucose concentration and calculating the total area under the blood glucose concentration curve. Twelve healthy young adults were recruited to a repeated measure randomised, single-blinded crossover trial to compare the effect of consuming noodles (180 g) containing 15%, 20% and 45% amylose on postprandial glycaemia. Fasting blood glucose concentrations were taken via finger-prick blood samples. Postprandial blood glucose …

Tactical Crop Management For Improved Productivity In Winter-Dominant Rainfall Regions: A Review, W K. Anderson, Ross Brennan, Kithsiri W. Jayasena, Svetlana Micic, John H. Moore, T Nordblom

Grain and Other Field Crops Research Articles

This study reviews published information on the tactical management decisions needed to maximise economic grain yield in winter-dominant rainfall regions of the Mediterranean type. Tactical decisions are defined as those relating to the period from immediately before sowing to harvest. Tactical management is the principal means by which farmers respond to changing environmental and short-term economic conditions as the season progresses. The review considers published evidence that underpins these decisions and relates to cereal crops (wheat, barley and oats), pulse crops (field pea, faba bean, chickpea and narrow-leaved lupin) and canola.

The criteria used to guide management decisions during the …

Bedstraw Eradication Program 2019/2020 - Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

Three-horned bedstraw (Galium tricornutum) is a competitive weed that can cause considerable yield loss in crops, and its seeds are contaminants of fodder and grain. The presence of bedstraw requires infested areas to be quarantined whilst a nine-year program is undertaken – six years of herbicide treatments followed by a three-year ‘release phase’.

In 2019/20 the Program reached a major milestone with quarantine restrictions fully lifted from one property and lifted from the arable areas of a second property. This is a major step toward eradicating bedstraw from Western Australia.

Skeleton Weed Program 2019/2020: Annual Report To Grain Growers, Department Of Primary Industries And Regional Development, Western Australia

Biosecurity published reports

2019/20 saw the Skeleton Weed Program expand its surveillance and control activities, with financial support from the IFS, specifically:

- Landholder incentives for paddock surveillance were increased and made available for surveillance undertaken on reinfested ‘Code 2’ paddocks. These changes were anticipated to enhance the level of surveillance for skeleton weed, enabling plants to be identified and treated and, therefore, reducing the risk of seed-set and spread.

- The IFS covered the cost of chemical for winter spraying undertaken on heavily infested paddocks. It was anticipated that this would help landholders reduce the level of skeleton weed infestation and, in …

The Effect Of Soil Ph On Phosphorus Content Of Clover Pasture, David Weaver, Robert Summers, David Rogers, Peta Richards

Resource management technical reports

Testing of pasture soils from 2009 to 2018, as part of DPIRD’s Whole Farm Nutrient Mapping (WFNM) project in the coastal catchments of south-west Western Australia (WA), indicated that soil pH was so low it could be limiting plant access to nutrients. Observations by some farmers who had been involved in the soil testing were that lime application had not increased pasture production, even when pH_Ca (pH measured in calcium chloride) tests indicated that phosphorus (P) should become more available by increasing soil pH. Farmers also wanted to know if they needed to apply more P than soil testing …
