We studied the effect of hurricanes on sub-tropical urban forests in San Juan, Puerto Rico. We found that the storms caused structural damage throughout the forest, but that landform position was important for understanding how the tree community changed as a result of hurricane disturbance.

Some cyanobacteria manage their buoyancy to achieve a vertical position in the water column that balances access to nutrients (at depth) with access to light (near the surface). We provide evidence that interflows during flooding events can destabilize the stratification regime and displace metalimentic cyanobacteria to the surface, giving the appearance of a cHAB.
