Ecuador’s Yasunı́ Man and the Biosphere Reserve—located at the intersection of the Amazon, the Andes mountains, and the equator—is home to extraordinary biodiversity and a recently contacted Amazonian indigenous group known as the Waorani (or Huaorani). Relatives of the Waorani, the Tagaeri and Taromenane, still live in voluntary isolation deep in the reserve, with no peaceful contact with the o...

Biosphere Reserves aim at being role models for biodiversity conservation. This study focuses on the unsuccessful conservation of waders (Charadrii) on wet grasslands in the Kristianstad Vattenrike Biosphere Reserve (KVBR) in southern Sweden. Predation on nests and young has been proposed as one reason contributing to the decline of waders. We explored this hypothesis by comparing two landscape...

In just the last few hundred years, humans extracted exploitable energy from these living and fossilized biomass fuels to build the modern industrial-technologica...
