A new study is providing an unprecedented examination of oxygen loss on coral reefs around the globe under ocean warming. The study captures the current state of hypoxia -- or low oxygen levels -- at 32 different sites, and reveals that hypoxia is already pervasive on many reefs.

Intense fishing and over-exploitation have led to evolutionary changes in fish stocks like cod, reducing both their productivity and value on the market. These changes can be reversed by more sustainable and far-sighted fisheries management. A new study shows that reversal of evolutionary change would only slightly reduce the profit of fishing, but would help regain and conserve natural genetic diversity.

New research shows how human-modified landscapes affect the diets of these marsupial scavengers.

A pioneering global study has found deforestation and forests lost or damaged due to human and environmental change, such as fire and logging, are fast outstripping current rates of forest regrowth.

Thanks to technological advances in microbial DNA analysis, researchers have discovered that mountaineers' boots aren't the only things leaving footprints on the world's tallest mountain. When someone sneezes on Everest, their germs can last for centuries.

A new study found that plants and small organisms in Arctic rivers could be responsible for more than half the particulate organic matter flowing to the Arctic Ocean. That's a significantly greater proportion than previously estimated, and it has implications for how much carbon gets sequestered in the ocean and how much moves into the atmosphere.

Dramatic differences between shallow and mesophotic reefs stress the importance of studying--and conserving--these vital ecosystems along their entire depth gradient.

A new study of Antarctic minke whales reveals a minimum size limit for whales employing the highly efficient 'lunge-feeding' strategy that enabled the blue whale to become the largest animal on Earth.

Decades of poor environmental and water management turned the Nile River Delta from a unique ecological habitat in the Sahara to one of the largest polluted areas on the planet, with tens of millions of people and migrating birds at risk of exposure to water-borne contaminants.

An international team of experts convened remotely as part of the Deep Ocean Stewardship Initiative's Climate Working Group to consider the deep-sea impacts of ocean-based climate intervention (OBCI). A research team has analyzed the proposed approaches to assess their potential impacts on deep-sea ecosystems and biodiversity. Their findings raise substantial concern on the potential impacts of these technologies on deep-sea ecosystems and call for the need for an integrated research effort to carefully assess the cost and benefits of each intervention.

A team of international researchers have found that the rivers in Arctic Canada and Alaska are not behaving as expected in response to the warming climate. The study focused on large rivers in the region and their movement through permafrost terrain. Their findings highlight the impact of atmospheric warming on these vital waterways.

Disconnected from the energy of the sun, the permanently ice-covered Arctic deep sea receives miniscule amounts of organic matter that sustains life. Bacteria which can harvest the energy released from submarine hydrothermal sources could thus have an advantage. Scientists found bacteria uniquely adapted to this geo-energy floating in deep-sea waters. They describe the role of these bacteria for biogeochemical cycling in the ocean.

Tibet is known as the 'Water Tower of Asia,' providing water to about 2 billion people and supporting critical ecosystems in High Mountain Asia and the Tibetan Plateau, where many of the largest Asian river systems originate. This region is also one of the areas most vulnerable to the compounding effects of climate change and human activities. Researchers are identifying policy changes that need to happen now to prepare for the future impacts projected by climate models.

Innovative battery researchers have cracked the code to creating real-time 3D images of the promising but temperamental lithium metal battery as it cycles. A team has succeeded in observing how the lithium metal in the cell behaves as it charges and discharges. The new method may contribute to batteries with higher capacity and increased safety in our future cars and devices.

Research into the ability of a wildfire to improve the health of a forest uncovered a Goldilocks effect -- unless a blaze falls in a narrow severity range, neither too hot nor too cold, it isn't very good at helping forest landscapes return to their historical, more fire-tolerant conditions.

A research team has shed new light on the importance of plant roots for below-ground life, particularly in the tropics. Millions of small creatures toiling in a single hectare of soil including earthworms, springtails, mites, insects, and other arthropods are crucial for decomposition and soil health. For a long time, it was believed that leaf litter is the primary resource for these animals. However, this recent study is the first to provide proof that resources derived from plant roots drive soil animal communities in the tropics.
