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.
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.
The first animal genus defined purely by genetic characters represents a new era for the sorting and naming of animals.
Gene-sequence data is changing the way that botanists think about their classification schemes. A recent name-change for a common houseplant resulted from the discovery that it belonged in an overlooked genus.
Modelers find evidence that a combination of competition, predation and evolution will push ecosystems toward species diversity anywhere in the universe.
The rapid, unorthodox emergence of a new finch in the Galápagos hints that speciation isn’t rare. New hybrid species may quietly appear and disappear without anyone noticing.
Mitonuclear conflict — a struggle between the genes in a cell’s nucleus and its mitochondria — might sometimes split species in two.
Despite swapping DNA through interbreeding, butterflies and other animals can maintain distinct species.
A large new study of ovenbird lineages questions the extent to which competing species push each other to evolve.
