- 25 August 2013
The results demonstrate that phylogeny and function are sufficiently linked that this 'predictive metagenomic' approach should provide useful insights into the thousands of uncultivated microbial communities for which only marker gene surveys are currently available.
Herbivore vs. nutrient control of marine primary producers: context-dependent effects.
It is suggested that human alteration of food webs and nutrient availability have significant effects on primary producers but that the effects vary among latitudes and primary producers, and with the inherent productivity of ecosystems.
Response to Comment on "Opposing Effects of Native and Exotic Herbivores on Plant Invasions"
It is found that non-native plants were more susceptible to native generalist herbivores than were native plants, and this finding supports the hypothesis that evolutionary naïveté leaves plants at greater risk of attack by newly encountered generalist Herbivores.
Herbivore species richness and feeding complementarity affect community structure and function on a coral reef

It is shown that herbivore species richness can be critical for maintaining the structure and function of coral reefs, because complementary feeding by diverse herbivores produces positive, but indirect, effects on corals, the foundation species for the ecosystem.
Chronic nutrient enrichment increases prevalence and severity of coral disease and bleaching.

Experimental evidence that chronic nutrient exposure leads to increases in both disease prevalence and severity and coral bleaching in scleractinian corals, the major habitat-forming organisms in tropical reefs is presented and simple improvements to water quality may be an effective way to mitigate some coral disease epizootics and the corresponding loss of coral cover in the future.
Impact of Herbivore Identity on Algal Succession and Coral Growth on a Caribbean Reef
The species-specific effects of herbivorous fishes suggest that a species-rich herbivore fauna can be critical in providing the resilience that reefs need for recovery from common disturbances such as coral bleaching and storm damage.
Temperature-induced mismatches between consumption and metabolism reduce consumer fitness.
It is found that metabolism and consumption exhibit different scaling relationships with temperature and are mismatched at high temperatures, which led to a dramatic reduction in ingestion efficiency and potentially in consumer fitness.
Nutrient versus herbivore control of macroalgal community development and coral growth on a Caribbean reef
It is found that herbivores could suppress macrophyte accumulation at sites with increased nutrient availability, and that fishes may have fed more on nutrient-enriched corals than previously thought.
Opposing Effects of Native and Exotic Herbivores on Plant Invasions
Exotic species are widely assumed to thrive because they lack natural enemies in their new ranges. However, a meta-analysis of 63 manipulative field studies including more than 100 exotic plant…
Herbivory and the Resilience of Caribbean Coral Reefs: Knowledge Gaps and Implications for Management
Key contingencies that will modify the rela- tionships between herbivores, algae, and corals are discussed and critical knowledge gaps are identified that limit the ability to predict when and where Herbivores are most likely to facili tate coral persistence and recovery.
