Study Resolves Controversy Over Nitrogen's Ocean 'Exit Strategies'
New findings may settle a decades-long debate over how nitrogen is removed from the ocean. Understanding nitrogen cycling is crucial to understanding the productivity of the oceans as well as the global climate.
Climate Change Drove Evolution of Ice Age Predators
New scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today.
Microbes and Mass Extinction
A new study shows how microbes may be guilty of causing the largest known mass extinction in Earth's history.
Counting Calories in the Fossil Record
Why did the ancestors of clams and oysters flourish after one of the worst mass extinctions in Earth’s history while another class of shelled creatures, the brachiopods, sharply decline? By using fossils to calculate the food intake of both groups, scientists are one step closer to solving one of paleontology’s great mysteries.
Large Predators Roamed Oceans Soon after Permian Extinction
A new study shows that large predators roamed the oceans soon after the End-Permian extinction--suggesting that ecosystems recovered more rapidly than previously thought.
Ancient Food Webs Show Modern Structure after Mass Extinction
A new study reveals that an ancient food web was organized much like modern food webs--despite the 48 million years of evolution that separate them.
A Scientist Proposes New Naming System for All Life on Earth
A Virginia Tech researcher has developed a new way to classify and name organisms based on their genome sequence.
A Serious Threat for Arctic Biodiversity
A new study outlines how irreplaceable wildlife and habitats in the Arctic are under threat from climate change. The report includes work from 253 scientists from 15 different countries.
New Maps Reveal Locations of Species at Risk as Climate Changes
An international team of scientists has produced global maps showing how fast and in which direction local climates have shifted.
Mass Extinction May Not Cause All Organisms to 'Shrink'
A new study suggests that the sizes of organisms following mass extinction events may vary more than previously thought.
