The particular geographical position of Chile, characterized by its long latitudinal extension, has drawn attention to a number of naturalists and scientists. The natural condition of “mainland island” with extremely arid conditions on the north and the prolonged presence of the Andes, define a unique endemic biota on the planet. In addition, Chile presents high vegetation diversity, product of environmental heterogeneity, related to a very active biogeographic history. Native Tree species reflect this particular biota, with almost 50% of endemism and a total richness of 98 species in continental Chile. This richness is distributed through 35 families and 59 genera, tree species distributions are concentrated in a narrow latitudinal band between 37-38°S degrees, main hypothesis of these patterns are found in the distribution of  ice fields during the  last glacial maximum (LGM), result in the retreatment of flora in “refugia” due to ice progress. These refugia have been supported from paleodata evidences for different taxa. Using recently developed historical, current and future climate surfaces under a species distribution modelling approach we analyze the identification and spatial characterization of refugia in the central-south area of Chile. The distribution of these refugia is evaluated under recent and future climate-change signal in order to propose new conservation areas to complement and prepare the current network of protected areas for climate-change impacts.

Species on the Move

An International Conference Series

The conference brings together scientists and natural resource managers working in the disciplines of global change, biogeography and evolution, and relevant in contexts of natural resource management, biodiversity management and conservation, and theoretical ecology.


Species responses to climate change is a rapidly evolving research field, however, much of our progress is being made in independent research areas: e.g. understanding the process vs responding to the implications, terrestrial vs marine ecosystems, global meta-analyses vs in depth species-specific approaches. This interdisciplinary conference develops connections between these parallel streams, and across temporal and spatial scales.
