Effects of flow and temperature on growth and photophysiology of scleractinian corals in Moorea, French Polynesia.

To test for threshold effects in the response of coral physiology to increasing seawater flow, field and laboratory experiments were conducted in Moorea. First, the growth of juvenile massive Porites spp. and branching P.

Switching from negative to positive density-dependence among populations of a cobble beach plant.

Interactions among species occur across a continuum from negative to positive and can have a critical role in shaping population and community dynamics. Growing evidence suggests that inter- and intra-specific interactions can vary in strength or even switch direction (i.e.
