Flora and vegetation of Lejía lagoon, a desert ecosystem of the high Puna in northern Chile
ABSTRACT The puna is an ecosystem located in the desert plateau above 3500 m elevation in the Andes Range that covers parts of north- eastern Chile, north-western Argentina, south-eastern Peru and mid-western Bolivia between 15° and 28° S latitude. Laguna Lejía is a shallow lake set in an endorheic...
