Identification of areas exposed to storm-tide inundation is of importance for coastal flood risk management. In June 2016 the coincidence of a storm surge with a high spring tide caused severe inundation across the coast of NSW. Settlements in low-lying areas of estuarine environments were particularly at risk due to the potential enhancement of extreme water levels by riverine flooding. Traditional flood risk assessments do not account for the latter driver, even though the degree of impact on flood extent can vary with the catchment size of an estuarine environment. This study compares flood extent generated from static ("bathtub") and …
Moss Δ13c: An Accurate Proxy For Past Water Environments In Polar Regions, Jessica Bramley-Alves, Wolfgang Wanek, Kris French, Sharon A. Robinson

Increased aridity is of global concern. Polar regions provide an opportunity to monitor changes in bioavailable water free of local anthropogenic influences. However, sophisticated proxy measures are needed. We explored the possibility of using stable carbon isotopes in segments of moss as a fine-scale proxy for past bioavailable water. Variation in δ13C with water availability was measured in three species across three peninsulas in the Windmill Islands, East Antarctica and verified using controlled chamber experiments. The δ13C from Antarctic mosses accurately recorded long-term variations in water availability in the field, regardless of location, but significant disparities in δ13C between species …

Private-sector organizations play a critical role in shaping the food environments of individuals and populations. However, there is currently very limited independent monitoring of private-sector actions related to food environments. This paper reviews previous efforts to monitor the private sector in this area, and outlines a proposed approach to monitor private-sector policies and practices related to food environments, and their influence on obesity and non-communicable disease (NCD) prevention. A step-wise approach to data collection is recommended, in which the first ('minimal') step is the collation of publicly available food and nutrition-related policies of selected private-sector organizations. The second ('expanded') step …
Characterizing The Litter In Postfire Environments: Implications For Seedling Recruitment, Andrew J. Denham, Robert Whelan, Tony D. Auld

Litter accumulation after fire influences the magnitude of seed predation and seed germination. How litter accumulation and patchiness influence postfire seedling recruitment is poorly known. Species with persistent seed banks have seeds available for germination in the immediate postfire period. In contrast, plants with transient seed banks must flower after fire to place seeds in the postfire habitat. In southeastern Australian sclerophyll forests, most seedling recruitment occurs within 3 yr after fire. We found that less litter had accumulated in sites mass, including some species with very light seeds. In contrast, the seed mass of transient seed bank species is …

Evaporation is an extremely powerful cooling process. When totally evaporated from the skin surface, sweat can remove body heat at a rate of 2.43 kJ«g"\ Humans therefore control sweat secretion to maintain thermal homeostasis. Since humans are capable of extended sweat rates approximating 30 g'min"1, it is possible to remove heat at rates -73 kJ-min"1. Assuming a 20% efficiency, such heat loss will support a normothermic total energy use of 1520W. This equates with an external work rate of 304W, eliciting an oxygen consumption >3.5 /«min"1. However, while man has a great capacity to both work and dissipate metabolically-derived heat, …
