corals

Corals create tiny vortices to absorb oxygen for survival, but this mechanism fails under high temperatures. The survival process involves an invisible, previously unknown dance of activity across their living surfaces.

Norfolk Island’s unique corals face a triple threat from disease, El Niño, and government-approved dredging. Scientists warn that sediment and pollution from cattle farming, cleared land, and wastewater contribute to coral disease and algae outbreaks.

Researchers found that the remains of foundation species like oysters, corals, and trees can significantly influence ecosystems long after their death, either supporting or hindering future generations. The study, published in Science Advances, analyzed 10 ecosystems and revealed that dead species often modify physical structures or resource availability, challenging previous assumptions about their ecological roles.
