Ecological consequences of major hydrodynamic disturbances on coral reefs

Article Abstract:

The effects of hydrodynamic disturbances on coral reef communities are examined using oceanographic models. These disturbances have a major role in determining species zonation and coexistence on coral reefs and are also the critical determinants of how coral assemblages will respond to changes in the frequency and intensity of tropical storms associated with a changing climate.

Predicted recurrences of mass coral mortality in the Indian Ocean

Article Abstract:

Research predicts geographical patterns in the timing of mass coral mortality. Data indicate that coral reefs located 10-15 degrees south of Indian Ocean will be affected every 5 years and the warmest sites are perhaps affected last. Furthermore, lethal temperatures affecting corals vary by 6 C but at 2 C they acclimatize and prolong their survival up to about 100 years.

Microfluidic sorting in an optical lattice

Article Abstract:

Research describes the interaction of an optical microscopic particle sorter with a three-dimensional optical lattice. Results indicate that the strength of the interaction depends on the particle optical polarizability and sorted by size and refractive index. Data show that the sorting efficiency is close to 100%, with values of 96% or higher for concentrated solutions.
