Collapse of macrophytic communities in a eutrophicated coastal lagoon.

Variability in Nitrate Uptake Kinetics of Phytoplankton Communities in a Mediterranean Coastal Lagoon

Nitrate uptake kinetics of different phytoplankton communities exhibit great variability over a 1-year period. Classical saturation kinetics accompanied by an induction phase are shown by blooms of Chaetoceros sp. in low nitrate waters. Biphasic kinetics, with transition points between 10 and 50 ìM, are shown by blooms of Skeletonema costatum and flagellates, while unsaturated kinetics (up to 1...

Distribution of picophytoplankton communities from brackish to hypersaline waters in a South Australian coastal lagoon

BACKGROUND Picophytoplankton (i.e. cyanobacteria and pico-eukaryotes) are abundant and ecologically critical components of the autotrophic communities in the pelagic realm. These micro-organisms colonized a variety of extreme environments including high salinity waters. However, the distribution of these organisms along strong salinity gradient has barely been investigated. The abundance and co...

Implementation challenges of climate change adaptation initiatives in coastal lagoon communities in the Gulf of Mexico

This paper explores some key challenges the Mexican government may face when implementing climate change adaptation initiatives in coastal lagoon communities in the Mexican state of Tabasco, in the Gulf of Mexico. I discuss some challenges state initiatives of this type may encounter considering the existence of local contentious political issues among various actors – fishers and the state-own...

Short Term CO2 Enrichment Increases Carbon Sequestration of Air-Exposed Intertidal Communities of a Coastal Lagoon

In situ production responses of air-exposed intertidal communities under CO2 enrichment are reported here for the first time. We assessed the short-term effects of CO2 on the light responses of the net community production (NCP) and community respiration (CR) of intertidal Z. noltei and unvegetated sediment communities of Ria Formosa lagoon, when exposed to air. NCP and CR were measured in situ...
