Abstract Headwater streams play a large role in aquatic greenhouse gas emissions. Carbon dioxide (CO 2 ) and dissolved oxygen often undergo changes through diel cycles. However, methane (CH 4 nitrous oxide (N O) have unknown dynamics. Here, we reveal consistent patterns CO , CH N O over cycles during flood events using high‐frequency continuous observations subtropical headwater stream. Diel were most pronounced baseflow. Increased nighttime discharge due to higher groundwater inputs...
Abstract Greenhouse gas (GHG) emissions from freshwater streams are poorly quantified in sub-tropical climates, especially the southern hemisphere where land use is rapidly changing. Here, we examined distribution, potential drivers, and of carbon dioxide (CO 2 ), nitrous oxide (N O) methane (CH 4 ) eleven Australian with varying catchment uses yet similar hydrology, geomorphology, climate. These were a source CO (74 ± 39 mmol m −2 day −1 CH (0.04 0.06 N O (4.01 5.98 µmol to atmosphere....
Pesticides, including insecticides and fungicides, are major contaminants in the effluent from intensive agricultural systems, such as greenhouses. Because of their constant use persistence, some pesticides can accumulate soil and/or run off into adjacent waterways. Microbial communities degrade pesticides, bioreactors with enhanced microbial have potential to facilitate decontamination before is released environment. In this study, we sampled along a gradient immediately below greenhouses,...
Coastal blue carbon habitats perform many important environmental functions, including long-term and anthropogenic contaminant storage. Here, we analysed twenty-five 210Pb-dated mangrove, saltmarsh, seagrass sediment cores from six estuaries across a land-use gradient to determine metal, metalloid, phosphorous sedimentary fluxes. Cadmium, arsenic, iron, manganese had linear exponential positive correlations between concentrations, flux, geoaccumulation index, catchment development. Increases...
Changing land use in subtropical and tropical catchments to farmland can result higher nitrogen (N) loss aquatic ecosystems. Here, we developed a lumped water N balance model estimate regional losses creeks at catchment scale within understudied Australia. The conceptual CoCa-RFSGD was extended by the mass top sub soil adding cycle transformation estimates depending on meteorological, properties. impact of pristine agricultural catchment-wide quality using only loworder creek samples as...
