Skyrocketing animal diversity a half-billion years ago was linked to spikes and dips in marine oxygen levels, according to a detailed geological study.
New work raises the estimated diversity of viruses in the seas more than twelvefold and lays the groundwork for a better understanding of their impact on global nutrient cycles.
In harsh ecosystems around the world, microbiologists are finding evidence that “microbial seed banks” protect biodiversity from changing conditions.
By reconstructing prehistoric food webs and analyzing the diverse interactions of humans with other species, the ecologist Jennifer Dunne is developing a new understanding of sustainability through network science.
For decades, researchers have commonly assumed that higher oxygen levels led to the sudden diversification of animal life 540 million years ago. But one iconoclast argues the opposite: that new animal behaviors raised oxygen levels and remade the environment.
Modelers find evidence that a combination of competition, predation and evolution will push ecosystems toward species diversity anywhere in the universe.
To assess the ocean’s health, ecology’s “rugged individualists” learned to get with the big data program.
