Where is all the Brevetoxin in Florida Dolphins?

After over 500 bottlenose dolphins washed ashore during a decade of Florida red tides, puzzled scientists measured little to no brevetoxin in them. An unusual mortality event occurred in 2004 ...

Macrobenthos and megabenthos responses to long-term, large-scale hypoxia on the Louisiana continental shelf

The macrobenthos and megabenthos responses to long-term, recurring hypoxia on the Louisiana continental shelf were compared at four locations with different historical (2000–2010) episodes of annual exposure to bottom-water hypoxia. Measurements of abundance, biomass, species diversity, and community composition of ...
