| Resumo: | Marine Protected Areas (MPAs) are important mechanisms for reef conservation,
reducing local impacts such as pollution and overfishing, and helping corals to survive
global bleaching events. However, many of these areas do not account for climate change
in their planning, which may reduce the future protection of corals given that coral
distribution is likely to change due to ocean warming. We evaluated the
representativeness of zooxantelate shallow-water scleractinian corals and hydrocorals in
the current MPAs network in Brazil comparing it among categories (level of protection)
and jurisdictions (municipal, state or federal). We used gap analysis to investigate
changes in future MPA representativeness along the Brazilian province, under the most
extreme scenario predicted by the Intergovernmental Panel on Climate Change (IPCC,
RCP 8.5). We observed that 21 coral species are included in MPAs that allow sustainable
use and 19 in strict protection MPAs, and there are no predicted differences in coral
assemblage composition between categories or jurisdictions. MPAs coincide with the
areas of highest occurrence probability for corals in current and future projections, being
mostly represented by the sustainable use categories. As environmental conditions
change, subtropical regions will experience increases in coral occurrence probability and
may become key areas for coral conservation in the future. Therefore, adopting actions
which incorporate climate change in the planning of MPAs may contribute to the survival
of these organisms. |
