abstract = "1. Niche conservatism, i.e. the retention of a species'
fundamental niche through evolutionary time, is cornerstone for
biological invasion assessments. The fact that species tend to
maintain their original climate niche allows predictive maps of
invasion risk to anticipate potential invadable areas. Unravelling
the mechanisms driving niche shifts can shed light on the
management of invasive species. 2. Here, we assessed niche shifts
in one of the world's worst invasive species: the wild boar Sus
scrofa. We also predicted potential invadable areas based on an
ensemble of three ecological niche modelling methods, and
evaluated the performance of models calibrated with native vs.
pooled (native plus invaded) species records. By disentangling the
drivers of change on the exotic wild boar population's niches, we
found strong evidence for niche conservatism during biological
invasion. 3. Ecological niche models calibrated with both native
and pooled range records predicted convergent areas. Also,
observed niche shifts are mostly explained by niche unfilling,
i.e. there are unoccupied areas in the exotic range where climate
is analogous to the native range. 4. Niche unfilling is expected
as result of recent colonization and ongoing dispersal, and was
potentially stronger for the Neotropics, where a recent wave of
introductions for pig-farming and game-hunting has led to high
wild boar population growth rates. The invasive potential of wild
boar in the Neotropics is probably higher than in other regions,
which has profound management implications if we are to prevent
their invasion into species-rich areas, such as Amazonia, coupled
with expansion of African swine fever and possibly great economic
losses. 5. Although the originally Eurasian-wide distribution
suggests a pre-adaptation to a wide array of climates, the wild
boar world-wide invasion does not exhibit evidence of niche
evolution. The invasive potential of the wild boar therefore
probably lies on the reproductive, dietary and morphological
characteristics of this species, coupled with behavioural
thermoregulation.",
