Rapid range expansion and community reorganization in response to warming
Abstract Species ranges are expected to expand along their cooler boundaries in response to rising temperatures associated with current global climate change. However, this ‘fingerprint’ of climate change is yet to be assessed for an entire flora. Here, we examine patterns of altitudinal range chang...
