A New Perspective on the Temperature Inside Tropical Forests

Tropical forests host up to half of the planet’s biodiversity but up to now, ecological studies over tropical forests often relied on large scale datasets depicting open-air temperatures – that is, the temperature outside the forests, which can be several degrees different from the temperatures inside the forest.

Tropical forests host up to half of the planet’s biodiversity but up to now, ecological studies over tropical forests often relied on large scale datasets depicting open-air temperatures – that is, the temperature outside the forests, which can be several degrees different from the temperatures inside the forest. This limitation imposed a large barrier in our understanding on how species will respond to climate change.

The research coordinated at the University of Helsinki and the Finnish Meteorological Institute and led by associate professor Eduardo Maeda from the University of Helsinki, has now achieved a major step to overcome this limitation. The results have been published in the scientific journal Nature communication.

Hotspots of microclimate refugia

Temperature is a fundamental factor defining the survival, growth, and reproduction rate of species living inside tropical forests.
