Do fish suffer from oxygen starvation?

Larger fish are more likely to experience oxygen deficiency in warming water than smaller species. The same applies to fish with large cells, note researchers at Radboud University in their latest study. In addition, marine ...

Ocean warming threatens richest marine biodiversity

An international team of scientists led by researchers from the University of Adelaide has revealed that rates of future warming threaten marine life in more than 70% of the most biodiverse-rich areas of Earth's oceans.

Monarch butterfly populations are thriving in North America

For years, scientists have warned that monarch butterflies are dying off in droves because of diminishing winter colonies. But new research from the University of Georgia shows that the summer population of monarchs has remained ...

Capturing carbon with crops, trees and bioenergy

An integrated approach to land management practices in the U.S. can reduce carbon dioxide in the atmosphere far more than earlier estimates based on separate approaches, Michigan State University researchers say. Their research ...

Drought impedes carbon sequestration by earthworms

Soil-borne organisms, especially earthworms, break down leaves and other dead material, releasing nutrients and making the soil fertile while sequestering carbon in the soil and thus helping counteract climate change. During ...

A vicious cycle of oxygen loss threatens water quality in lakes

Scientists have recently confirmed that the world's lakes are rapidly losing oxygen. With a seven-year, whole-ecosystem study, a team of freshwater scientists at Virginia Tech has been one of the first to take the next step ...
