Percentage cover of coral reef associated algae increased significantly from 2003 to 2007 at two shelf edge sites in southwest Puerto Rico (42.8 % to 75.3% at Weinberg Reef and 67.4% to 81.8% at El Hoyo). While the increase ...

Baseline information on the water quality status of coral reefs and associated habitats of La Parguera, southwestern PR, is presented. Measurements of temperature, salinity, chlorophyll a , turbidity, fluorescence of ...

Juvenile coral survivorship (the proportion of juvenile colonies surviving from t 1 to t 2 ) was assessed by counting, photographing and mapping all juveniles found in 2003 within random permanent 0.25m 2 quadrats at four ...

Massive upstream migrations of neritid snails (Neritidae: Gastropoda) occur in tropical and subtropical streams worldwide, but their seasonality and proximate causes are unknown. We monitored massive upstream migrations ...
