The impacts of river regulation on aquatic biota have been extensively studied, but long-term assessments the restoration by environmental flows and principal mechanisms recovery rarely occurred. We assessed whether provision an flow regime (EFR) via decommissioning aqueduct a tributary stream altered downstream macroinvertebrate assemblages in highly regulated Snowy River, Australia. Macroinvertebrate reference control sites remained distinct despite flows. Invertebrate detrimentally...
The use of wetlands as a treatment approach for nitrogen in runoff is common practice agroecosystems. However, nitrate not the sole constituent present agricultural and other biologically active contaminants have potential to affect removal efficiency. In this study, impacts combined effects four veterinary antibiotics (chlortetracycline, sulfamethazine, lincomycin, monensin) on nitrate-N efficiency saturated sediments were evaluated coupled microcosm/mesocosm scale experiment. Veterinary...
The practice of using therapeutic and prophylactic veterinary antibiotics in livestock farming is a worldwide phenomenon. Over the last decade, there has been growing concern antibiotic residues entering environment via animal manure. Similar studies have focused on occurrence biological effects land-applied feedlots; however, limited research conducted persistence feedlots. Therefore, objective this study was to evaluate persistence, fate, transport surface water runoff feedlot sediment...
Highlights Stabilization structures are only effective at stabilized segments. Erosion increased in two of the six segments post-stabilization period. Deposition decreased all Jetties reducing erosion but also prone to fail. Abstract . The effectiveness streambank stabilization is insufficiently quantified. Although such clearly reduce or eliminate local scale, little known about associated effects on unstabilized reaches immediately upstream and downstream. This study measured deposition...
