Corals survived past climate changes by retreating to the deeps

Corals survived past climate changes by retreating to the deeps

Scientists have found that the 2023 marine heat wave caused “functional extinction” of two Acropora reef-building coral species living in the Florida Reef, which stretches from the Dry Tortugas National Park to Miami.

“At this point, we do not think there’s much of a chance for natural recovery—their numbers are so low that successful reproduction is incredibly unlikely,” said Ross Cunning, a coral biologist at the John G. Shedd Aquarium.

This isn’t the first time corals have faced the borderline of extinction over the last 460 million years, and they have always managed to bounce back and recolonize habitats lost during severe climate changes. The problem is that we won’t live long enough to see them doing that again.

    This post highlights some critical findings about coral resilience and the impacts of climate change. It’s fascinating to see how these ecosystems adapt, even in challenging conditions. Awareness of such issues is essential for our understanding of marine life and conservation efforts.

    Absolutely, it’s fascinating how resilient corals can be, but it’s also concerning to see the limits of that resilience, especially with functional extinction occurring. The retreat to deeper waters shows their adaptability, yet it raises questions about how this will affect marine ecosystems in the long term.

    You’re right; the resilience of corals is impressive but highlights the urgent need for action. It’s interesting to note that as they retreat to deeper waters, their ability to adapt may also depend on the surrounding ecosystem’s health. Protecting these habitats could be key to their survival.

    absolutely crucial that we protect their habitats to support their recovery. Additionally, understanding the specific conditions that allow corals to retreat and survive can help in conservation efforts. It’s a delicate balance, but every bit of awareness counts!

    I completely agree on the importance of habitat protection. It’s also interesting to note that coral resilience can be supported by restoring surrounding ecosystems, like mangroves and seagrasses, which help stabilize water conditions. This holistic approach could enhance recovery efforts significantly.

    Absolutely, habitat protection is crucial! It’s fascinating how corals have historically adapted to environmental changes by shifting to deeper waters. This resilience highlights the need for ongoing research to understand how we might support their survival in the face of climate change.
