Dust contributes valuable nutrients to Sierra Nevada forest ecosystems

Collecting dust isn’t usually considered a good thing. But dust from as close as California’s Central Valley and as far away as Asia’s Gobi Desert provides nutrients, especially phosphorus, to vegetation in the Sierra Nevada Mountains, a team of scientists has found.

Forests fight global warming in ways more important than previously understood

Forests play a complex role in keeping the planet cool, one that goes far beyond the absorption of carbon dioxide, new research has found. Trees also impact climate by regulating the exchange of water and energy between the Earth’s surface and the atmosphere, an important influence th

Tackling resilience: Finding order in chaos to help buffer against climate change

“Resilience” is a buzzword often used in scientific literature to describe how animals, plants and landscapes can persist under climate change. It’s typically considered a good quality, suggesting that those with resilience can withstand or adapt as the climate continues t

Tiny bacterium provides window into whole ecosystems

William Blake may have seen a world in a grain of sand, but for scientists at MIT the smallest of all photosynthetic bacteria holds clues to the evolution of entire ecosystems, and perhaps even the whole biosphere. The key is a tiny bacterium called Prochlorococcus, which is the most

Corals Die as Global Warming Collides with Local Weather in the South China Sea

In the South China Sea, a 2°C rise in the sea surface temperature in June 2015 was amplified to produce a 6°C rise on Dongsha Atoll, a shallow coral reef ecosystem, killing approximately 40 percent of the resident coral community within weeks, according to a study published in Scienti

Climate Change and an "Overlooked" Nutrient: Silica

Among ecologists, carbon gets all the glory. Scientists examine its critical role in plant growth and decay, they chart its contributions to greenhouse gases, and they measure its sequestration in earth, sea, and sky. Often overlooked in all this research is the humble element silicon
