This paper is a survey of all the known marine Chlorophyta of southern Australia, from the south-west corner of Western Australia to about the Victoria- New South Wales border, and including Tasmania. Full references to each species are given, all established synonomy, the type locality of each species and where the type specimen is deposited, and a summary of the known distribution. Critical notes on many species are given also.

The lethaeine genus Austroxestus Woodward, 1962, and its type-species A. carnarvoni Woodward are redescribed. The type locality of this species is the Carnarvon Range, Queensland; new records are from eastern New South Wales. The following are described: A. australiensis, sp. nov., from Tasmania, Victoria and eastern Queensland, A. taylori, sp. nov., from New South Wales, and A. westraliensis, sp. nov., from south-west Western Australia. The variation and distribution of A. australiensis are discussed. The four species are keyed out.

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.

The sand-hopper Bellorchestia mariae sp. nov. is described from Honeymoon Bay on the north coast of Jervis Bay, NewSouth Wales, Australia. It is the sister species of B. richardsoni Serejo & Lowry, 2008 and appears to have a limited dis-tribution from about Narrawallee in the south to northern Jervis Bay. The distribution of B. richardsoni Serejo & Lowry,2008 is extended from Point Ricardo, Victoria, northwards to Ulladulla on the New South Wales coast. A new synonymyis proposed for the sand-hopper Notorchestia quadrimana (Dana, 1852) which includes N. novaehollandiae (1899) andN. lobata Serejo & Lowry, 2008. It is considered to be a wide-ranging species from Shark Bay in Western Australia aroundthe south coast to at least Maitland Bay in central New South Wales. The beach-hopper Orchestia dispar Dana, 1852 isdescribed from Valla Beach in northern New South Wales and moved to the new genus Vallorchestia. This is the first re-cord of V. dispar since its original description 160 years ago. The beach-hopper Platorchestia smithi sp. nov. is describedfrom Brooms Head, New South Wales, Australia. It is common on ocean beaches from Bendalong in the south to Ballina in northern New South Wales. South of Bendalong beach-hoppers on ocean beaches appear to be absent.

scholarly journals Whole-farm profit and the optimum maternal liveweight profile of Merino ewe flocks lambing in winter and spring are influenced by the effects of ewe nutrition on the progeny's survival and lifetime wool production

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.

Subsurface Soil

The aim of this study was to establish whether surface incorporated liming materials could reduce subsurface acidity. Three sites on the southwest slopes of New South Wales, between Wagga and Albury, were sampled at 2 cm depth increments to 16 cm, 5 years after the liming materials were applied. Limestone and dolomite had been applied at 0,2 and 8 tlha in 3 replicates. At 2 t/ha the effect of the liming materials on pH was largely confined to the depth of incorporation. At 8 t/ha substantial pH increases occurred to 6 cm or more below the depth of incorporation. In general, the movement of Mg>Ca> HCo3 (pH), and was consistent with the soil's ability to hold those cations and to neutralize alkalinity respectively. Agriculturally realistic liming rates are not likely to ameliorate subsurface soil acidity on the south-west slopes of New South Wales.

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.
