The threat of climate change to freshwater pearl mussel populations

Article Abstract:

Direct and indirect effects of climate change are examined for Scotland's freshwater pearl mussels. Direct effects include temperature and precipitation levels; indirect effects include sea level, habitat availability, host fish stock declines, and human activity responses. The article concludes that conservation efforts are indicated.

Hypersaline cyanobacterial mats as indicators of elevated tropical hurricane activity and associated climate change

Article Abstract:

The article examines the effects of the 1999 hurricane season on salt lakes in the Bahamas. Hurricane activity reduces lake salinity via freshwater input; this periodic change in lake chemistry fosters development of cyanobacterial mats. Implications for climatic change research are discussed.
