Soil-dwelling microbes are indispensable for life in the mountain forest, but the variety and number of microbes in the mountain rainforest soil drops with increasing altitude.
The beauty and diversity of the flora in the mountain rainforest is primarily maintained by bats, birds and insects, making them perfect subjects for the researchers to study....

Waterproofs are essential here: The Cerro del Consuelo, at an altitude of 3,200 metres above seal level, is home to the highest weather radar installation in the world.
A spade, rubber boots and provisions: Two teams of researchers set off to perform a concurrent ecological survey of the pasture cleared by slash-and-burn and of pristine mountain rainforest.
The road to the Estación Científica San Francisco is long and steep. The bus has to cross the El Tiro pass, climbing to an altitude of 2,800 metres, before descending 1,000 metres into the valley as it winds its way into the Amazon.
