Methane availability in freshwaters is usually associated with spatial-temporal variation methanogenesis. Unusually, however, natural gas macro-seeps occur along the Condamine River eastern Australia which elevate ambient water-column methane concentrations more than 3,000 times. We quantified oxidation rates and total microbial methanotroph community composition (through amplification sequencing of 16S rRNA particulate monooxygenase (pmoA) genes), factors mediating this variation, reaches...
Extreme rainfall from an ex-tropical cyclone caused a major flood event in the Logan River system southeast Queensland, Australia. This resulted significant plume, containing nutrients and sediment, being discharged into adjacent estuary/Bay system. The spatial extent of higher phytoplankton biomass (Chl a) matched distribution nutrient sediment concentrations post-flood, suggesting fuelled production. Particulate nitrogen (PN) constituted over 50 % total floodwaters, with lower proportions...
Biogeochemical maps of coastal regions can be used to identify important influences and inputs that define nearshore environments biota. tracers also track animal movement their diet, monitor human development, evaluate the condition habitats species. However, beneficial applications spatial biogeochemical analysis are hindered by a limited understanding how tracer distribution is affected different land ocean-based influences. To help address these knowledge gaps, we determined trends three...
Abstract Effective environmental management hinges on monitoring drivers of change and effectively communicating results to stakeholders. While animals are valuable for engagement, few programs successfully integrate metrics quantifying their assemblages. We studied fish responses factors (including landscape context water quality) in a 3-year survey across six ecosystems 13 estuaries eastern Australia (for >1800 surveys), developed novel predicted versus observed approach monitoring,...
Embayments and the biota they support are highly susceptible to disturbance within adjacent catchments. Examining timing magnitude of impacts arising from human-induced in these systems is often limited due absence long-term monitoring. Moreton Bay south-eastern Queensland a shallow embayment that receives inflows 21220-km2 catchment. In this study, diatom abundances, pigment (chlorophyll-a, phaeopigments) biogenic silica concentrations were evaluated composite sediment central explore...
