Sediment-routing systems continuously transfer information and mass from eroding source areas to depositional sinks. Understanding how these systems alter environmental signals is critical when it comes to inferring source-area properties from the sedimentary record. We measure cosmogenic 10Be and 26Al along three large sediment-routing systems ( ∼ 100 000 km2) in central Australia with the aim of tracking downstream variations in 10Be-26Al inventories and identifying the factors responsible for these variations. By comparing 56 new cosmogenic 10Be and 26Al measurements in stream sediments with matching data (n = 55) from source areas, we show that 10Be-26Al inventories in hillslope bedrock …

The value of history is, indeed, not scientific but moral … it prepares us to live more humanely in the present, and to meet rather than to foretell, the future - Carl Becker. Becker's quote reminds us of the importance of revealing and understanding historical practices in order to influence actions in the future. There are compelling reasons for uncovering this history, in particular to better inform government policy makers and health advocates, and to address the impacts of growing community expectations to 'make the punishment fit the crime'.

A hydrogel-dielectric elastomer system, polyacrylamide and poly(dimethylsiloxane) (PDMS), is adapted for extrusion printing for integrated device fabrication. A lithium-chloride-containing hydrogel printing ink is developed and printed onto treated PDMS with no visible signs of delamination and geometrically scaling resistance under moderate uniaxial tension and fatigue. A variety of designs are demonstrated, including a resistive strain gauge and an ionic cable.
Social Systems In Habitat-Specialist Reef Fishes: Key Concepts In Evolutionary Ecology, Marian Y.L Wong, Peter M. Buston
Social Systems In Habitat-Specialist Reef Fishes: Key Concepts In Evolutionary Ecology, Marian Y.L Wong, Peter M. Buston

A major focus in evolutionary ecology lies in explaining the evolution and maintenance of social systems. Although most theoretical formulations of social system evolution were initially inspired by studies of birds, mammals, and insects, incorporating a wider taxonomic perspective is important for testing deeply entrenched theory. Here, we review the contribution of studies of habitat-specialist coral reef fishes to our understanding of the evolutionary ecology of animal social systems. These fishes are ecologically similar but display remarkable variation in mating systems, social organization, and sex allocation strategies. By reviewing recent research, we demonstrate their amenability for experimental testing of key …
A Comparison Of The Impact Of 'Seagrass-Friendly' Boat Mooring Systems On Posidonia Australis, Marie-Claire A. Demers, Andrew R. Davis, Nathan A. Knott

Permanent boat moorings have contributed to the decline of seagrasses worldwide, prompting the development of ‘seagrass-friendly’ moorings. We contrasted seagrass cover and density (predominantly Posidonia australis) in the vicinity of three mooring types and nearby reference areas lacking moorings in Jervis Bay, Australia. We examined two types of ‘seagrass-friendly’ mooring and a conventional ‘swing’ mooring. ‘Swing’ moorings produced significant seagrass scour, denuding patches of ∼9 m radius. Seagrass-friendly ‘cyclone’ moorings produced extensive denuded patches (average radius of ∼18 m). Seagrass-friendly ‘screw’ moorings, conversely, had similar seagrass cover to nearby reference areas. Our findings reinforce previous work highlighting the negative effects …

The present study uses remote-sensing imagery to estimate carbonate production of the complete One Tree Island reef system, Great Barrier Reef, using hydrochemical (alkalinity reduction) and census-based (budgetary) methods. For five sites representing different benthic cover types across the reef system, carbonate production is determined using hydrochemical techniques that incubate substrates in a local aquarium and measure total alkalinity, total ammonia nitrogen, and total oxidized nitrogen. Local estimates are scaled up to the reef-system scale using a WorldView-2 satellite image, which is ground truthed against a field data set of 350 spatially referenced records of benthic assemblage. Annual total reef …
