Using benthic foraminifera, we evaluate the ecological quality status (EcoQS) of transitional
waters of the Guanabara Bay (SE Brazil) by applying the diversity-based index exp (H′ bc) …

The important role mangrove forests play in sequestering organic carbon is well known, yet
rates of organic carbon accumulation in macro‐tidal mangrove ecosystems are poorly …

Coastal eutrophication and urban flooding are increasingly important components of global
change. Although increased seawater renewal by barrier openings and channelizing are …

Reductions of zooplankton biomasses and grazing pressures were observed during
overfishing-induced trophic cascades and concurrent oil spills at global scales. Recent …

Mangrove environments are important for maintaining biodiversity and carbon cycling.
However, these systems are being degraded at alarming rates around the world, particularly …

Four streams in the city of São Gonçalo, were sampled to evaluate their potential as sources
of nutrients to Guanabara Bay aiming to contribute with the government program to …

Mangrove ecosystems are dynamic and biodiverse environments with the capacity to
sequester more organic carbon per unit area, per time, than terrestrial forests, yet are among …

Agriculture activities in coastal catchments often contribute pollutant runoff such as nitrogen
