Zooplankton feeding by corals underestimated
Research by marine biologists from Wageningen University has shown that feeding on zooplankton by scleractinian corals has been greatly underestimated.

Scientists from Taiwan and Israel have found that octocorals are important reef builders. This exciting discovery makes us rethink the very nature of coral reefs.
Epizoic coral flatworms have been found to compete with their coral host for zooplankton. This finding is in agreement with the theory that symbiotic coral flatworms are parasitic.
Small polyped stony corals are often believed to simply rely on strong lighting and dissolved nutrients. But even these corals capture significant amounts of plankton.

This year is the International Year of the Reef; IYOR 2008. For this reason, the ARC Centre of Excellence for Coral Reef studies has published a series of lectures from the world’s leading coral scientists! Take a look at their website, where people such as Professor Ove Hoegh-Guldberg talk about climate change and coral reefs. The message is clear; the tides have to be turned when it comes to burning of fossil fuels! We NEED the coral reefs; Ecology: - coral reefs provide a habitat for a staggering amount of fish and invertebrate species Society and economy: - many people are dependent on the coral reefs worldwide (fishing, ecotourism and ornamental trade) - the Great Barrier Reef alone yielded an estimated gross of 10 billion USD in 2004, mainly from ecotourism Geology: - Coral reefs worldwide protect the coastline of 109 countries (think of the 2004 tsunami!) Have a look at the Centre of Excellence for Coral Reef studies website, and watch a video now, or have a look at a list of many presentations. |
