The Cost

Profitability of sheep production systems in southern Australia is optimised at a stocking rate that provides adequate nutrition for breeding ewes and enables efficient utilisation of grown pasture and supplements. In this paper we used bio-economic modelling to develop optimum liveweight1 profiles for spring-lambing Merino ewes in different environments. The modelling included the impacts of the ewe liveweight profile on the production of the ewe and the survival and lifetime wool production of her progeny. Fifteen ewe liveweight profiles were analysed for each region to determine the profitability of varying ewe liveweight at joining, varying rate of loss of liveweight after joining and the rate of gain in liveweight from the minimum to lambing. The analyses support the hypotheses that whole-farm profitability is sensitive to the liveweight profile of Merino ewe flocks and that there is a liveweight profile that maximises whole-farm profit. The variation between the most and least profitable ewe liveweight profile was $69 0002 per farm ($14.30/ewe) for south-west Victoria, $51 000 per farm ($8.70/ewe) for Great Southern Western Australia and $33 300 per farm ($9.70/ewe) for southern New South Wales. The changes in profit were due to differences in costs of feeding to achieve the ewe liveweight profile and its influence on the production of both the ewes and their progeny. Failure to include the impacts of liveweight profile on progeny survival and lifetime wool production incorrectly identifies the optimum ewe liveweight profile and provided inaccurate estimates of profitability. The optimum liveweight profiles for ewes lambing in spring were similar for all three regions and insensitive to changing commodity prices, pasture productivity and management. The optimum profile was to join ewes at ~90% of the standard reference weight of the genotype, lose a small amount of weight after joining and regain weight in late pregnancy to return to the joining weight by lambing. Regaining the liveweight lost in early pregnancy by lambing is the most important target to achieve. The cost per farm of missing this liveweight target by 1 kg was $13 000 ($2.60/ewe) for south-west Victoria, $8900 ($1.45/ewe) for Great Southern Western Australia and $5500 ($1.65/ewe) for southern New South Wales. By contrast, the cost per farm of missing the joining target by 1 kg was $5500 for south-west Victoria and less than $2000 across the other two regions. Whole-farm profit increased with increasing stocking rate up to an optimum and regardless of stocking rate there is an additional opportunity to increase whole-farm profit by up to 15% by managing ewes to achieve the optimum liveweight profile. This indicates that the optimum liveweight profile should be achieved by increasing the level of grain feeding and altering the timing of utilising the farm feed resources rather than manipulating stocking rate.

Metaprotella haswelliana (Mayer, 1882), the type species of Metaprotella, was originally described from Port Jackson, New South Wales, Australia and was reported from there in literature published between 1882 and 2003. However, the type specimens are lost and no further specimens could be found in recent surveys in New South Wales waters. The only current records are from Albany, Western Australia and from Port Phillip Bay, Victoria. Based on the materials from Western Australia, the poorly known type species, Metaprotella haswelliana is redescribed, a neotype is assigned, and the genus Metaprotella Mayer, 1890 is redefined.

The Relationship

The genus Alfredella Masner & Huggert is revised. Alfredella tasmanica Masner & Huggert is redescribed, Al. teres (Buhl), comb. nov. is transferred to Alfredella from Amitus Haldeman, and Al. auriel Lahey, sp. nov. (New South Wales, Tasmania) and Al. mephisto Lahey, sp. nov. (Western Australia) are described as new. The genus Masnerium Polaszek, syn. nov. is treated as a junior synonym of Amitus, and its type species, M. wellsae Polaszek, is transferred to Amitus as Am. wellsae (Polaszek), comb. nov. The relationship between Alfredella and morphologically similar genera is discussed, and a key is provided to distinguish between Aleyroctonus Masner & Huggert, Alfredella, and Amitus.

Water Accumulation

Water striders and their allies (Hemiptera, Gerromorpha) are familiar inhabitants of water surfaces throughout the world. One of the most species-rich groups is the subfamily Microveliinae (Veliidae) and, in particular, the genus Microvelia Westwood, 1834. This genus comprises small or very small bugs inhabiting the nearshore areas of stagnant or slow-flowing fresh water. Accumulation of material during the past 30 years has shown that the Australian fauna of Microvelia is much richer and more diverse than previously recognised. In the present paper we discuss the subgeneric classification of the genus Microvelia based on the results of a phylogenetic analysis using maximum parsimony, describe three new subgenera and redescribe all previously known Australian species of the genus. The new taxa are: Microvelia (Austromicrovelia), subgen. nov. (type species: Microvelia mjobergi Hale, 1925) with the species Microvelia (Austromicrovelia) spurgeon, M. hypipamee, M. margaretae, M.�monteithi, M. tuberculata, M. myorensis, M. woodwardi, M. carnarvon, M. annemarieae, M. mossman, spp. nov. (all from Queensland), M. eborensis and M. milleri, spp. nov. (New South Wales), M. queenslandiae, M.�ventrospinosa, spp. nov. (New South Wales, Queensland), M. angelesi, M. alisonae, M. odontogaster, spp. nov. (Northern Territory), M. apunctata, sp. nov. (Northern Territory, Queensland), M. pennicilla, sp. nov. (Northern Territory, Western Australia), M. herberti, M. malipatili, M. torresiana, and M. australiensis, spp. nov. (Northern Territory, Queensland, Western Australia), Microvelia (Barbivelia), subgen. nov. (type species: Microvelia barbifer, sp. nov.) with the species Microvelia (Barbivelia) barbifer, sp. nov. (Queensland) and M. falcifer, sp. nov. (Northern Territory); Microvelia (Pacificovelia), subgen. nov. (type species: Microvelia oceanica Distant, 1914) with the species M. tasmaniensis, sp. nov. (Tasmania), M. lilliput, and M. kakadu, spp. nov. (Northern Territory, Queensland, Western Australia). We further recognise the subgenus Microvelia (Picaultia), stat. nov. (type species: Picaultia pronotalis Distant, 1913), and describe the following new species: Microvelia (Picaultia) justi and M. paramega, spp. nov. (Northern Territory, Queensland, Western Australia), and M. cassisi, sp. nov. (New South Wales). Finally, Microvelia fluvialis weiri Malipatil, 1980, is synonymised with Microvelia fluvialis Malipatil, 1980. Keys to adults of all species are provided and their distributions mapped.

Historical Accounts

The numbat (Myrmecobius fasciatus ) was formerly widespread across most of southern Western Australia, South Australia and western New South Wales. It delined in the early 1900's, possibly due to foxes, cats, or an epizootic. Protection through control of foxes and cats, and translocation, has resulted in several populations being re-established at sites of historical distribution.

The genus Amperea Adr. Juss. contains eight species, six of which are confined to the south-west of Western Australia. The seventh occurs only in central Australia while the eighth ranges from central Queensland to Tasmania and extends to the south-east of South Australia. A. simulans, from Western Australia, is described as new, and A. xiphoclada var. papillata and A. xiphoclada var. pedicellata from New South Wales are recognised as new varieties; A. xiphoclada var. pedicellata is probably now extinct. Lectotypes are chosen for A. micrantha and A. volubilis. All species are described in detail and a key to identify them is provided. The diagnostic relevance of a range of attributes of the genus is reviewed as is its classificatory history.* The first of a projected series of revisions of genera traditionally included in Stenolobeae Benth., and others related to them, which are intended to form the basis of future Flora of Australia accounts.

Constitutional systems of Westminster heritage are increasingly moving towards fixed-term parliaments to, amongst other things, prevent the Premier or Prime Minister opportunistically calling a ‘snap election’. Amongst the Australian states, qualified fixed-term parliaments currently exist in New South Wales, South Australia and Victoria. Queensland, Tasmania and Western Australia have also deliberated over whether to establish similar fixed-term parliaments. However, manner and form provisions in those states' constitutions entrench the Parliament's duration, Governor's Office and dissolution power. In Western Australia and Queensland, unlike Tasmania, such provisions are doubly entrenched. This article considers whether these entrenching provisions present legal obstacles to constitutional amendments establishing fixed-term parliaments in those two states. This involves examining whether laws fixing parliamentary terms fall within section 6 of the Australia Acts 1986 (Cth) & (UK). The article concludes by examining recent amendments to the Electoral Act 1907 (WA) designed to enable fixed election dates in Western Australia without requiring a successful referendum.
