Coral Reefs Under Rapid Climate Change and Ocean Acidification
As the International Year of the Reef 2008 begins, scaled-up management intervention and decisive action on global emissions are required if the loss of coral-dominated ecosystems is to be avoided. Expand
New dates and new rates for divergence across the Isthmus of Panama
Patterns of divergence exhibited by allozymes and the mitochondrial COI gene are highly concordant for 15 pairs of snapping shrimp in the genus Alpheus, indicating that they provide a reasonable basis for estimating time since cessation of gene flow. Expand
Diversity and distribution of coral-associated bacteria
Analysis of the branching coral Porites furcata showed that bacterial ribotypes can also be structured spatially within colonies, and corals and reefs represent landscapes of diverse, ecologically structured prokaryotic communities. Expand
Divergence in proteins, mitochondrial DNA, and reproductive compatibility across the isthmus of Panama.
Measurements of biochemical and reproductive divergence for seven closely related, transisthmian pairs of snapping shrimps indicate, however, that isolation was staggered rather than simultaneous, and the four least divergent pairs provide the best estimate for rates of molecular divergence and speciation.

Sibling species in the sea
A large number of abundant, well-studied, or economically important taxa have recently been shown to be complexes of sibling species, and the broad habitat and geographic distributions characteristic of many marine species require reevaluation. Expand
Landscape ecology of algal symbionts creates variation in episodes of coral bleaching
It is found that the ecologically dominant Caribbean corals Montastraea annularis and M. faveolata can act as hosts to dynamic, multi-species communities of Symbiodinium, implying that physiological acclimatization is not the only mechanism by which corals cope with environmental heterogeneity. Expand
Climate change impacts on marine ecosystems.
In marine ecosystems, rising atmospheric CO2 and climate change are associated with concurrent shifts in temperature, circulation, stratification, nutrient input, oxygen content, and oceanExpand
Evolution and the latitudinal diversity gradient: speciation, extinction and biogeography.
Two major hypotheses for the origin of the latitudinal diversity gradient are reviewed, including the time and area hypothesis and the diversification rate hypothesis, which hold that tropical regions diversify faster due to higher rates of speciation, or due to lower extinction rates. Expand
Baselines and Degradation of Coral Reefs in the Northern Line Islands
Protection from overfishing and pollution appears to increase the resilience of reef ecosystems to the effects of global warming, and reefs without people exhibited less coral disease and greater coral recruitment relative to more inhabited reefs. Expand
Mitochondrial and Nuclear Genes Suggest that Stony Corals Are Monophyletic but Most Families of Stony Corals Are Not (Order Scleractinia, Class Anthozoa, Phylum Cnidaria)
A more comprehensive analysis of Scleractinia and various outgroups, based on two mitochondrial genes and analyses of nuclear genes of a subset of taxa to test unexpected relationships, suggests a future of greater taxonomic stability. Expand
