The development, growth, and space occupation by the canopy and rhizosphere of a temperate Mediterranean seagrass meadow of Cymodocea nodosa, and the possible effects of meadow seasonal development on sediment redox conditions, were examined during the 1998 growth season. The meadow supported maximum biomass of leaves and rhizomes during July, and maximum root biomass in August. The meadow main...

Global increases in the occurrence of large, severe wildfires in forested watersheds threaten drinking water supplies and aquatic ecology. Wildfire effects on water quality, particularly nutrient levels and forms, can be significant. The longevity and downstream propagation of these effects as well as the geochemical mechanisms regulating them remain largely undocumented at larger river basin s...

Cold marine sediments harbor endospores of fermentative and sulfate-reducing, thermophilic bacteria. These dormant populations of endospores are believed to accumulate in the seabed via passive dispersal by ocean currents followed by sedimentation from the water column. However, the magnitude of this process is poorly understood because the endospores present in seawater were so far not identif...

The mangrove sediment from the Mae Klong River (MK) and Khon Canal (KK) revealed microplastics contamination in Estuary environment. Microplastic analyses were analyzed by using ZnCl2 density separation H2O2 digestion process. average concentrations of microplastic was 580 1690 items kg-1 dry weight samples MK KK. contained more coarse grain than KK sediment. lower concentration mainly related ...

Abstract. Salt marshes and seagrass meadows can sequester store high quantities of organic carbon (OC) in their sediments relative to other marine terrestrial habitats. Assessing stocks, sources, the transfer between habitats within coastal seascapes are each integral identifying role blue cycling. Here, we quantified exchanges meadows, salt marshes, unvegetated six bays along California coast....
