Harmful Algal Blooms and Eutrophication: Nutrient Sources, Composition, and Consequences
Although algal blooms, including those considered toxic or harmful, can be natural phenomena, the nature of the global problem of harmful algal blooms (HABs) has expanded both in extent and its public perception over the last several decades. Of concern, especially for resource managers, is the potential relationship between HABs and the accelerated eutrophication of coastal waters from human a...

15 صفحه اولNutrient excretion by fish in wetland ecosystems and its potential to support algal production
We used both direct measurement and bioenergetic methods to examine nitrogen and phosphorus (P) excretion by fathead minnows in two wetlands over 2 yr. We also assessed the potential importance of nutrient flux from fish by comparing excretion estimates to empirically derived estimates of algal P demand. Population-level estimates of P excretion across the four lake-years were high relative to ...
متن کاملDoes nutrient enrichment decouple algal–bacterial production in periphyton?
Coupled production between algae and bacteria in stream epilithon was assessed along a nutrient-enrichment gradient in 8 Texas streams with open canopies. Photosynthesis (PS) and bacterial biomass production (BBP) were measured simultaneously using a dual-label radioassay (C-HCO3 – uptake and H-L-leucine incorporation into protein) on multiple samples within a stream reach. PS and BBP were meas...
