Sentences with phrase «coral skeletal growth»

We examined changes in coral skeletal growth rates and partial mortality scars [11] to investigate the impact of the bleaching event in 2004 [16] on corals from different temperature variability regimes.

This provides the strongest evidence yet in favor of a biologically - controlled coral skeletal growth, the team reports today in Science.

Not exact matches

Now, scientists have suggested that corals have some active control over their skeletal growth — and that it may protect them from the worst ravages of ocean acidification.

To date, studies of aragonitic, scleractinian CWC responses to ocean acidification have frequently examined short - term acclimation, with effects on coral bio-mineralization, growth, and skeletal strength only becoming evident in experiments run for periods of a year or more (e.g., Tittensor et al., 2010).

Strontium staining was used as a proxy for coral growth rates, and skeletal samples were taken for boron isotope analysis.

However, apparently only the more severe bleaching events cause a reduction in skeletal growth rates; for instance, one study found growth anomalies in 95 % of corals from the Mesoamerican Reef related to severe bleaching in 1998, though only a single core (of 92 collected) showed an anomaly due to a less severe event in 1995 [11].

The spatial pattern in skeletal growth rates and partial mortality scars found in massive Porites sp. across the central and northern islands suggests that corals subject to larger year - to - year fluctuations in maximum ocean temperature were more resistant to a 2004 warm - water event.
