Resumo
Increasingly biodiversity has lost diversity around the globe because of the way
the human population have used natural resources. To reduce the impacts
caused by human activity, conservation units (CU) have been created to ensure
the maintenance of biodiversity. However, many conservation units were not
established following scientific criteria and its efficiency can therefore be
questioned. In this study we tried to evaluate the efficiency of conservation of
the Cerrado based on species richness and beta diversity of mammals currently
and in accord to climate change expected for 2080. We show through gap
analyzes that species are represented in the current system both in the current
climate and in the future. However, they have become rarer within CUs with
climate change. We show that CUs do not capture a greater diversity than
expected by chance. It is expected a larger number of species within the CUs in
2080, however, the number of species outside them will also be greater. As for
beta diversity, there will be a reduction of the index in 2080 and both outside
and within the UCs expected on average the same value. Climate change
became UC’s Cerrado more inefficient, there will be an increase in the number
of threatened species because of climate change interfering in the spatial
arrangement of species on the Cerrado. This draws attention to the evaluation
of systems of protected areas consider the spatial-temporal dynamics of the
species.
