Allopatric speciation biodiversity center of origin
2015/12/17
The Indonesian-Australian Archipelago is the center of the world's marine biodiversity. Although many
biogeographers have suggested that this region is a "center of origin," criticism of this theory...
Extensive sympatry, cryptic diversity and introgression throughout the geographic distribution of two coral species complexes
Acropora, ryptic species hybridization
2015/12/11
The identification of species is one of the most basic, and yet critically important, issues
in biology with far-reaching potential implications for fields such as biodiversity
conservation, populat...
Do fluctuating temperature environments elevate coral thermal tolerance?
Coral ! Climate change Acropora
2015/12/11
In reef corals, much research has focused on the
capacity of corals to acclimatize and/or adapt to different
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...
