Your cells' power plants were once free-living bacteriaSymbiosis is not just clownfish and anemones. Biologists think it built the complex cell itself, when ancient bacteria were absorbed and became mitochondria and chloroplasts. Part…
More than 80 percent of the world's species live in forestsForests shelter the great majority of known species, so clearing them wipes out homes on a vast scale while also feeding climate change. Deforestation is only one of many pressure…
The word 'ecosystem' was coined on request, for a mentor, in 1935Ecosystem feels like an ancient idea, but the word first appeared in print in 1935. The British ecologist Arthur Tansley wanted a term for the traffic of materials between living …
What exactly makes a species 'endangered'? The IUCN has hard numbersEndangered is not a vague alarm word. The IUCN Red List applies specific thresholds: a population down 20 percent in five years with fewer than 2,500 breeding adults qualifies, an…
