  Tropical rainforests exhibit a rich repertoire of spatial patterns emerging
from the intricate relationship between the microscopic interaction between
species. In particular, the distribution of vegetation clusters can shed much
light on the underlying process regulating the ecosystem. Analyzing the
distribution of vegetation clusters at different resolution scales, we show the
first robust evidence of scale-invariant clusters of vegetation, suggesting the
coexistence of multiple intertwined scales in the collective dynamics of
tropical rainforests. We use field data and computational simulations to
confirm our hypothesis, proposing a predictor that could be particularly
interesting to monitor the ecological resilience of the world's 'green lungs'.
