Coral reefs are one of the most diverse ecosystems on the planet. What are the abiotic and biotic interactions that structure this diverse ecosystem? Corals are members of the phylum Cnidaria, a ...

Coral reefs, the "rainforests of the sea," provide habitats for 25% of all marine life. Critical to global biodiversity, they ...

" These incredible structures are built by tiny animals called polyps that secrete calcium carbonate to form their hard skeletons. They occur in more than 100 countries and territories, and whilst ...

Coral reefs, often called the rainforests of the sea, are among the most biologically diverse and ecologically important ecosystems on Earth. Despite covering less than 1% of the ocean floor, they ...

For more than a quarter billion years, coral reefs did far more than brighten shallow seas. Long before humans appeared, ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

The ring-shaped coral islands known as atolls, like this one in the Maldives Islands in the Indian Ocean, may trace their formation to sea levels repeatedly rising and falling over hundreds of ...
