Contribution of dispersal syndromes to beta diversity
The sign (positive or negative effect) of the contribution of dispersal
syndromes to turnover was consistent for most scales, but its value
changed depending on the scale (fig. 4). None of the habitats studied
showed a consistent pattern regarding the effect of dispersal syndromes.
In most cases, the effect of dispersal syndromes on turnover was not
significant, and its absolute contribution ranged between 0.1 to 0.3.
Endozoochorous species consistently decreased turnover at the three
scales analyzed except in Terceira island, where they increased it. On
the other hand, epizoochorous species increased turnover at all scales,
with significant values of multisite βSIM being found
for the intermediate and small scales. Anemochorous and hydrochorous had
no significant contribution to turnover at any scale.
