?Not even pioneering assisted-reproduction techniques can bolster the odds of successful reproduction in bleached coral reefs, according to a new study from the Smithsonian Conservation Biology Institute and the University of Hawaii. The findings indicate that Smithsonian scientists and partners collecting and freezing coral cells will be much more limited in where they collect samples as bleaching events become more frequent worldwide. #ScienceSavesSeas #WeSaveSpecies #instascience
The next step for researchers is to identify places around the world where they can preserve coral that are rare, have important genes, are robust, or have significant abilities to adapt. Our researchers will also next try to replicate this detailed reproductive assessment with coral in the genus Acropora to see if the results are similar. This group is the world’s reef-building coral, the most sensitive to many stressors and thus the most frequently studied.
Globally, greenhouse gasses from burning fossil fuels are warming the oceans, making them more acidic and causing corals to stress and bleach. As a result, the corals are more susceptible to emergent diseases. Locally, there are numerous causes of bleaching: pollution and sedimentation from poor land-use practices, nutrient run-off from farms and waste-treatment plants, and destructive practices such as dynamite fishing and trawls. Without action, coral reefs and many of the animals that depend on them may cease to exist within the next 40 years.
