Effect of sewage nutrients on algal production, biomass and pigments in tropical tidal creeks.
Microalgal blooms can result from anthropogenic nutrient loadings in coastal ecosystems. However, differentiating sources of nutrients remains a challenge. The response of phytoplankton and benthic microalgae (BMA) to nutrient loads was compared across tropical tidal creeks with and without secondary treated sewage. Primary productivity in the water column was limited by nitrogen availability i...
متن کاملThe effect of tidal forcing on biogeochemical processes in intertidal salt marsh sediments
BACKGROUND Early diagenetic processes involved in natural organic matter (NOM) oxidation in marine sediments have been for the most part characterized after collecting sediment cores and extracting porewaters. These techniques have proven useful for deep-sea sediments where biogeochemical processes are limited to aerobic respiration, denitrification, and manganese reduction and span over severa...
متن کاملBiogeochemical Processes and Implications for Nutrient Cycling
The availability and cycling of nutrients is determined by an interaction of physical, chemical, and biological processes in an ecosystem. This interaction of processes, collectively known as biogeochemistry, is important as it determines the forms, transformations, and ultimate fate of nutrients in a given system. This chapter focuses on biogeochemical processes in springs and spring runs with...
متن کاملBiogeochemical processes along a nutrient gradient in a tropical ombrotrophic peatland
Biogeochemical properties, including nutrient concentrations, carbon gas fluxes, microbial biomass, and hydrolytic enzyme activities, were determined along a strong nutrient gradient in an ombrotrophic peatland in the Republic of Panama. Total phosphorus in surface peat decreased markedly along a 2.7 km transect from the marginal Raphia taedigera swamp to the interior sawgrass swamp, with simil...
