Plastic pollution has become a global environmental crisis, with an estimated 11 million tons of plastic entering the oceans each year. As larger plastic debris breaks down into microplastics, these tiny particles are transported throughout marine ecosystems by ocean currents, th

Hydrothermal vents on the ocean floor host a broad range of rare and unusual ecosystems. They can be spread far apart, yet there is often overlap among the creatures that inhabit them. Researchers, including those from the University of Tokyo, are answering a long-standing questi

On a summer afternoon in the Sierra Nevada, a mountain pond can look calm and still, reflecting granite peaks and alpine sky. But beneath the surface, these small, shallow waters are anything but stable. In fact, they are among the most thermally variable aquatic ecosystems on Ea

Researchers combined satellite data and visitor surveys at dark-sky parks to quantify the economic value of dark skies amid rising light pollution.

Researchers have identified "DNA switches" that become active as honeybee larvae grow into worker bees, offering new insight into the development of these important pollinators and the ecosystems they support.

Nitrogen is essential for all living organisms, but in many ecosystems it is in short supply. Plants and soil microbes both rely on nitrogen to grow, leading to intense competition below ground. Researchers at The University of Manchester have uncovered how plants and soil microb

A global analysis of fish biodiversity using environmental DNA (eDNA) reveals how human activity and climate influence biodiversity patterns in river ecosystems. An international research team led by the University of Zurich, Eawag and Yunnan University has found that in warmer c

Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly influence the spread of this environmental toxi

Freshwater ecosystems worldwide have been suffering from declining oxygen levels—a trend known as deoxygenation—that threatens biodiversity, fisheries and ecosystem stability. However, a new study published in Nature Geoscience offers hope: targeted nutrient management via wastew

Long-term conservation policies may help restore freshwater ecosystems and prevent extreme species loss, new research suggests.

Over recent decades, harmful algal blooms have become increasingly common. These blooms often consist of bacteria called "cyanobacteria" in freshwater ecosystems. They can produce debilitating toxins, suffocate marine life by depleting oxygen in the water, and make water unsafe f

Researchers at King Abdullah University of Science and Technology (KAUST) led one of the first global assessments of how marine ecosystems responded during the first year when global temperatures temporarily exceeded 1.5°C above pre-industrial levels.
