The population dynamics of red kangaroos (Macropus rufus) in the Australian arid zone is tightly linked with environmental factors, which partly operate via the survival of juvenile animals. A crucial stage is the young-at-foot (YAF) stage when kangaroos permanently exit the pouch. We have examined the thermal biology of YAF red kangaroos during ages from permanent pouch exit until weaning. Over a wide range of environmental temperatures (ambient temperature [T-a] -5 degrees to 45 degreesC), YAF red kangaroos had a mass-specific metabolism that was generally twice that of adults, considerably higher than would be expected for an adult marsupial of …

The installation of one-way tidal restricting floodgates in regions containing acid sulphate soils has increased the problems associated with acid drainage in many areas of coastal Australia. In southeastern NSW, one-way flap gates installed in deep flood mitigation drains maintain a low groundwater table and increase acid production and transport. Moreover, by restricting the intrusion of brackish water into the drainage system, the floodgates create a reservoir of acidic water. Recent studies suggest that by allowing a controlled amount of brackish water into the drains, via modified floodgates, buffering agents can neutralize the acidic water. A fifteen-month study was undertaken …

The topological partitioning of electronic properties approach at Hartree-Fock level is used to investigate charge transfer response in a water dimer. Distributed polarizability components are employed to calculate the change in electron density under external fields. Field-induced charge flow between the water monomers is most significant along the direction of the hydrogen bond. The molecular polarizability of the molecules in the dimer is reduced owing to formation of the hydrogen bond.
