Phylogenetic placement and the timing of diversification in Australia's endemic Vachellia (Caesalpinioideae, Mimosoid Clade, Fabaceae) species

The genus Vachellia Wight & Arn. has a pantropical distribution, with species being distributed through Africa, the Americas, Asia and Australia. The relationships among the lineages from Africa and America are well understood, but the phylogenetic placement and evolutionary origins of the Australian species of Vachellia are not known. We, therefore, sequenced four plastid genes from representatives of each of the nine Australian species of Vachellia, and used Bayesian inference to assess the phylogenetic placement of these lineages, and a relaxed molecular clock to assess the timing of diversification. The Australian species of Vachellia form a well-supported monophyletic clade, with molecular-dating analysis suggesting a single dispersal into Australia 6.5 million years ago (95% range 13.9-2.7 million years ago). Diversification of the Australian clade commenced more recently, c. 3.1 million years ago (95% range 9.2-1.2 million years ago), perhaps driven by the increased aridification of Australia at this time. The closest relatives to the Australian Vachellia were not from the Malesian bioregion, suggesting either a long-distance dispersal from Africa, or two separate migrations through Asia. These results not only improve our understanding of the biogeography of Vachellia species, but also have significant implications for the biological control of invasive Vachellia species in Australia

NSC32244

A new multidisciplinary mooring DOMS (Deep Ocean Monitoring Station) was deployed at the PAP time series observatory in June 2007 with a design specification duration of 18 months. Various features failed and the mooring ultimately parted after 47 days. The top part of the mooring was recovered by R/V Pelagia in September 2007.This report summarises the problems experienced and makes recommendations for future mooring design and deployment. • Mooring failure: Detailed analyses have been carried out using data on the mooring behaviour and on the recovered structure. The root cause of the failure was that the design allowed 550m of line to float on the surface under certain slack conditions. This line then became entangled with the surface buoy on day 192 (11th July) causing stresses and strains for which the mooring was not designed. Probably associated with this change in configuration was the parting of a shackle at 1000m depth following which the top section of the mooring drifted away from its anchor on day 221 (9th August). This failure has prompted a redesign of the mooring so that entanglement can not occur again but in addition it has stimulated a change in the way complex moorings are designed. Such organisational changes have now been made and will be an essential feature of all future design processes.• Data transmission: Although the bi-directional satellite telemetry link to the buoy functioned correctly throughout, the inductive telemetry link to the underwater sensors experienced problems from the outset and ultimately failed. The reasons for this have been identified and solutions recommended.• Sensor failures: Diverse problems were encountered most of which have been identified and solutions found.• Corrosion: This was more serious than expected and mitigation strategies are being developed.• Navigation light failure: The problem has been identified and a solution found

Shift Recording in Residential Child Care

Recording is a task often perceived by residential child care workers as boring or taking time away from the ‘real work’, direct engagement with young people. It is required by legislation and policy but has been undertheorized and treated as a technical/rational task. In this essay, Foucauldian and feminist perspectives are applied to shift recording, a routine aspect of residential practice, in order to problematize the positivist approach assumed in legislation and policy. The analysis suggests that this approach represses emotional aspects of care and subjugates particular forms of knowledge, such as young people’s experiences. Recording inevitably involves ethical choices and treating it as technical/rational task obscures its ethical implications. This essay concludes that greater attention needs to be given to the ethical aspects of shift recording in order to challenge practice that oppresses young people by failing to recognize their individuality and silencing their voices
