Reshuffled Rivers Bolster the Amazon’s Hyper-Biodiversity
The lush biodiversity of the Amazon may be due in part to the dynamics of branching rivers, which serve as invisible fences that continuously barricade and merge bird populations.
Wildfires of Varying Intensity Can Be Good for Biodiversity
The spate of furious wildfires around the world during the past decade has revealed to ecologists how much biodiversity and “pyrodiversity” go hand in hand.
The Year in Biology
While the study of the SARS-CoV-2 virus was the most urgent priority, biologists also learned more about how brains process information, how to define individuality and why sleep deprivation kills.
How Neutral Theory Altered Ideas About Biodiversity
The simple insight that most changes are random had a profound effect on genetics, evolution and ecology.
New Fish Data Reveal How Evolutionary Bursts Create Species
In three bursts of adaptive change, one species of cichlid fish in Lake Tanganyika gave rise to hundreds.
A Physicist’s Approach to Biology Brings Ecological Insights
The physicist Jeff Gore tests theories about microbe communities experimentally and finds new rules governing ecological stability.
Out-of-Sync ‘Loners’ May Secretly Protect Orderly Swarms
Studies of collective behavior usually focus on how crowds of organisms coordinate their actions. But what if the individuals that don’t participate have just as much to tell us?
Some Animals Have No Microbiome. Here’s What That Tells Us.
To stay healthy, humans and some other animals rely on a complex community of bacteria in their guts. But research is starting to show that those partnerships might be more the exception than the rule.
Nature Versus Nurture? Add ‘Noise’ to the Debate.
We give our genes and our environment all the credit for making us who we are. But random noise during development might be just as important.
