New research has defined a series of thresholds that can be used to reliably predict the impact of water quality levels on coral health.
Further research into dredging pressures on coral has revealed that even a very fine layer of sediment can prevent coral larvae from settling on a surface and building on the coral community.
Sponges can alleviate pressure from sediments in the short-term, but researchers have found that longer-term exposure may still compromise fitness.
More than 90 images, giving a glimpse into the rare soft coral gardens of Australia’s remote northwest, have been compiled in a photographic field guide.
An investigation into the ability of bleached corals to cope with dredging related stressors has found that several species of thermally bleached corals cannot clear sediment that has smothered them.
Scientists have developed new framework for assessing likely impacts of dredging on coral populations, and for evaluating the timeframes and likelihood of population recovery from impacts.
Scientists have tested a breakthrough in sensing sediment risks to reefs that uses bundles of fibre optic sensors and hundreds of countersunk holes to mimic coral.
An examination of whether dredging operations suspended during generic windows of environmental sensitivity could reduce the impacts on marine life has found the marine invertebrates, seagrasses and macroalgae too diverse to be covered by a one-size-fits-all approach.
Early stages of fish life, such as eggs and larvae, are most likely to suffer lethal impacts from dredging-related stress according to new research.
