Resumo
Climate variables are commonly used to predict
suitability for species occurrence, but local processes,
such as landscape changes, may affect habitat
suitability. We identified levels of exposure to
deforestation of suitable climatic areas for eight bat
species in the Brazilian Cerrado and explored how
sensitivity to land-use changes could reduce their
persistence. We created scenarios of sensitivity to
land-use changes using theoretical species persistence
thresholds to natural vegetation loss in landscapes
(70%, 50% and 30% of loss). We also assessed sensitivity
to land-use changes using empirical data. Species are
under higher exposure to land-use changes in the
southern Cerrado, a region more affected by humans
due to its proximity to major urban areas. Changes in
land use in the Cerrado mostly affect Myotis nigricans,
Artibeus cinereus and Platyrrhinus lineatus. Empirically
derived scenarios encountered significant thresholds
at 50% of natural vegetation loss in landscapes for
Artibeus lituratus and P. lineatus. Deforestation has
already affected a half of the Cerrado area, but in
terms of possibly vulnerable suitable areas, a larger
proportion has been lost, amounting to up to 80% of the
suitable area. We propose that information on species specific sensitivity thresholds to habitat loss and on the
exposure of suitable landscapes to land-use changes
can be useful to assessing species vulnerability.
