Climate change may push canopy-dwelling plants and animals out of the tree-tops due to rising temperatures and drier conditions, argues a new study published in Proceedings of the Royal Society B. The development may be akin to “flattening” the tiered vegetation structure that characterizes the rainforest ecosystem. The conclusion is based on surveys of frogs and other canopy-dwelling animals in Singapore and the mountains of the Philippines. Brett Scheffers of James Cook University and colleagues found that the “rainforest’s vertical strata provide climatic gradients much steeper than those offered by elevation and latitude, and biodiversity of arboreal species is organized along this gradient.”
