Scientists have thought that salps […]

Oxygen levels in the world’s temperate freshwater lakes are declining rapidly — faster than in the oceans — a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality. Research published on June 2, 2021, in Nature found that oxygen levels in surveyed lakes across the temperate zone […]

University of Pennsylvania biologist Katie Barott and colleagues found that corals maintain their ability to resist bleaching even when transplanted to a new reef. Credit: S. Matsuda Corals that withstood a severe bleaching event and were transplanted to a different reef maintained their resilient qualities, according to a new study […]

Sampling with the ROV in the home of the investigated microbes, the Guaymas-Beckens.

Deep down in the seafloor anaerobic microbes consume large amounts of methane, a potent greenhouse gas when it enters […]

But scientists say there is a high risk that these relocations are accidentally spreading diseases and parasites. The new report published […]

Stylophora pistillata, a common stony coral in the Indo-Pacific. Credit: Kevin Wyman/Rutgers University Scientists’ findings suggest corals will withstand climate change. Charles Darwin, the British naturalist who championed the theory of evolution, noted that corals form far-reaching structures, largely made of limestone, that surround tropical islands. He didn’t know how […]

In recent years, advancements in DNA sequencing have exposed a large amount of hidden diversity in reef-building […]

Credit: Katharine Clayton, University of Plymouth A tiny flatworm found commonly on the coasts of western Europe and North America is living proof that species may be able to evolve and adapt to rapid climate change. Research by the University of […]

Floating solar farms could help to protect lakes and reservoirs from some of the harms of climate change, a new study suggests. However, given the complex nature of water bodies and differing designs of solar technologies, there could also be detrimental ecosystem impacts of deploying floating solar arrays. Credit: Giles […]
