Resumen:
Aim Explaining why some invasions fail while others succeed is a prevailing
question in invasion biology. Different factors have been proposed to explain the
success or failure of exotics. Evidence suggests that climate similarities may be
crucial. We tested this using 12 species of the genus Pinus that have been widely
planted and shown to be highly invasive. Pinus is among the best-studied group of
exotic species and one that has been widely introduced world-wide, so we were
able to obtain data on invasive and non-invasive introductions (i.e. unsuccessful
invasions; areas where after many decades of self-sowing seeds there is no
invasion).
Location World-wide.
Methods We developed species distribution models for native ranges using a
maximum entropy algorithm and projected them across the globe. We tested
whether climate-based models were able to predict both invasive and non-invasive
introductions.
Results Appropriate climatic conditions seem to be required for these long-lived
species to invade because climates accurately predicted invasions. However,
climate matching is necessary, but not sufficient to predict the fate of an
introduction because most non-invasive introductions were predicted to have
triggered an invasion.
Main conclusions Other factors, possibly including biotic components, may be
the key to explaining why some introductions do not become invasions, because
many areas where Pinus is not invading were predicted to be suitable for invasion
based solely on climate.
