thermal environments, but the majority of work has focused
on distinctions in mean tempe...
Coral Bleaching Independent of Photosynthetic Activity
Photosynthetic Activity Coral Bleaching
2015/12/11
The global decline of reef-building corals is due in part to
the loss of algal symbionts, or ‘‘bleaching,’’ during the
increasingly frequent periods of high seawater temperatures
[1, 2]. During ble...
