‘Species Repulsion’ Enables High Biodiversity in Tropical Trees
Because tree seedlings don’t grow as well when close to their parents, more tree species can be packed into tropical forests.
The Key to Species Diversity May Be in Their Similarities
New modeling work suggests why nature is more diverse than niche-based ecological theory predicts.
How Pools of Genetic Diversity Affect a Species’ Fate
A new, deeper understanding of how the breeding structure of species affects their genetic diversity is giving conservationists better tools for saving animals.
She Tracks the DNA of Elusive Species That Hide in Harsh Places
On Mount Everest and in the Peruvian Andes, Tracie Seimon uses DNA to study how species and ecosystems respond to climate change, pathogens and other influences.
Why ‘De-Extinction’ Is Impossible (But Could Work Anyway)
Several projects are aiming to bring back mammoths and other species that have vanished from the planet. Whether that’s technically possible is beside the point.
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.
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.
