Habitat destruction is a key threatening process for amphibians. Modified or anthropogenic waterbodies can be used to compensate habitat loss, with several amphibian species utilising created modified waterbodies. We measured usage of anthropogenic/modified by adult and tadpole frog species, including threatened in coastal wallum eastern Australia. Nine road trenches/ditches, 8 artificial ‘lake...

Heparin is a complex glycosaminoglycan, derived mainly from pig mucosa, used therapeutically for its anticoagulant activity. Yet, owing largely to the chain complexity, progressive effects of environmental conditions on heparin structure have not been fully described. A systematic study influence acidic hydrolysis length and substitution has therefore conducted. Changes in sulfation pattern, mo...

Acidic soils often have high concentrations of dissolved aluminium (Al) and iron (Fe) in their solutions. The objective of this study was to determine potential solid phases controlling dissolved A1 and Fe concentrations in pyritic (FeS2) soils undergoing oxidation.. Soil samples were extracted with distilled-deionised H20 after reacting for 14,21 and 28 days (d) at 25fl"C. Soil water extracts ...
