The Significance And Vulnerability Of Australian Saltmarshes: Implications For Management In A Changing Climate, Neil Saintilan, Kerrylee Rogers
The Significance And Vulnerability Of Australian Saltmarshes: Implications For Management In A Changing Climate, Neil Saintilan, Kerrylee Rogers
Faculty of Science, Medicine and Health - Papers: part A
We review the distribution, status and ecology of Australian saltmarshes and the mechanisms whereby enhanced atmospheric carbon dioxide and associated climate change have influenced and will influence the provision of ecosystem goods and services. Research in temperate and subtropical saltmarsh has demonstrated important trophic contributions to estuarine fisheries, mediated by the synchronised mass-spawning of crabs, which feed predominantly on the C-4 saltmarsh grass Sporobolus virginicus and microphytobenthos. Saltmarshes also provide unique feeding and habitat opportunities for several species of threatened microbats and birds, including migratory shorebirds. Saltmarshes increased in extent relative to mangrove in Australia in both tide- and wave-dominated …
Middle Carboniferous-Early Triassic Eclogite-Blueschist Blocks Within A Serpentinite Mélange At Port Macquarie, Eastern Australia: Implications For The Evolution Of Gondwana's Eastern Margin, Allen P. Nutman, Solomon Buckman, Hiroshi Hidaka, Tomoyuki Kamiichi, Elena Belousova, Jonathan Aitchison

The New England Orogen of easternmost Australia is dominated by suites of Palaeozoic to earliest Mesozoic rocks that formed in supra-subduction zone settings at Gondwana's eastern margin. On the northern New South Wales coast at Rocky Beach, Port Macquarie, a serpentinite mélange carries rare tectonic blocks of low-grade, high-pressure, metamorphic rocks derived from sedimentary and igneous protoliths. Dominant assemblages are glaucophane. +. phengite. ±. garnet. ±. lawsonite. ±. calcite. ±. albite blueschists and lawsonite-bearing retrogressed garnet. +. omphacite eclogites. In some blocks with sedimentary protoliths, eclogite forms folded layers within the blueschists, which is interpreted as Mn/(Mn. +. Fe) compositional …
Micro-Biomechanics Of The Kebara 2 Hyoid And Its Implications For Speech In Neanderthals, Ruggero D'Anastasio, Stephen Wroe, Claudio Tuniz, Lucia Mancini, Deneb T. Cesana, Diego Dreossi, Mayoorendra Ravichandiran, Marie Attard, William C. H Parr, Anne Agur, Luigi Capasso

The description of a Neanderthal hyoid from Kebara Cave (Israel) in 1989 fuelled scientific debate on the evolution of speech and complex language. Gross anatomy of the Kebara 2 hyoid differs little from that of modern humans. However, whether Homo neanderthalensis could use speech or complex language remains controversial. Similarity in overall shape does not necessarily demonstrate that the Kebara 2 hyoid was used in the same way as that of Homo sapiens. The mechanical performance of whole bones is partly controlled by internal trabecular geometries, regulated by bone-remodelling in response to the forces applied. Here we show that the …
