Scientists Say They Have Bred Corals to Better Resist Warm Oceans
The study said their selective breeding methods resulted in improved heat tolerance of adult corals, even within a single generation.

Scientists Say They Have Bred Corals to Better Resist Warm Oceans
Scientists have for years been observing corals that show more heat-resistant qualities. These corals are used as the parents for new corals.

The researchers said their experiments showed that breeding heat-tolerant characteristics into different corals could be a useful tool “to improve population

resilience However, the team noted the method would likely not be enough by itself to effectively protect corals.

This is because increasingly intense ocean warming is expected to continue if additional steps are not taken to reduce the worldwide effects of climate

change. The scientists noted, therefore, that methods to reproduce heat-resistant corals must be a part of overall efforts that require “urgent climate action.”

The research team’s experiments were carried out during a five-year project launched by Newcastle’s James Guest.

The effort received financial support from the European Research Council. The team said it carried out selective breeding tests involving two different characteristics.

The first sought to improve the tolerance to the release of a short, intense heat event over 10 days with a temperature rise of 3.5 degrees Celsius.

The second tested results for a less intense, but long-term temperature rise of 2.5 degrees Celsius over one month.

The study found that “selecting parent colonies for high rather than low heat tolerance increased the tolerance of adult offspring."
- Public domaingeneral-american

The result was observed for corals experiencing either a short, intense heat event or a long-term temperature rise.

The team estimated that about 25 percent of the increased heat tolerance was linked to genes passed down from parents of the corals.

These genes can also be influenced by other selective breeding methods to produce heat-tolerance characteristics, the researchers said.

Newcastle researcher Liam Lachs helped lead the study.

He said in a statement the research clearly demonstrated that selective breeding can be a valuable tool in improving the health of corals influenced by warming oceans.

However, he noted the tested methods are not a complete solution and that “more research is needed to maximize breeding results.
- Public domaingeneral-american

The researchers said they plan next to lead efforts to carry out large experiments on corals in the wild to confirm the study results.

These efforts would involve seeding selectively bred corals directly on ocean reefs or deploying corals raised in a laboratory. I’m Bryan Lynn.
