Resumen
Reefs are sensitive ecosystems that have undergone accelerated changes, caused both
by global changes and local impacts. Understanding the onset, location and magnitude of these
changes is key to future mitigation, conservation and restoration efforts. Although this implies
a great research effort, it can be facilitated if we add different sources of information, such as
the knowledge retained by different reef users. We assessed changes in the landscape of South
Atlantic reefs in their two main regions (tropical and subtropical, all located in Brazil) by
interviewing different key stakeholders: fishers, divers, and researchers. For 57% of the
stakeholders, the health of South Atlantic reef environments has been declining since the 1970s,
evidenced by the decline of herbivorous parrotfishes (Labridae: Scarinae) and reef builders
(massive corals). These same stakeholders also noticed an increase in algae and small
damselfishes (Pomacentridae) and indicated the recovery of sea turtle populations. Accessing
the memory of reef users allows one to date the beginning of change processes, identify
regionalities and specificities in them, in addition to identifying groups of organisms most
vulnerable to changes. This information is important to better target protection and conservation
efforts, especially in developing countries, where marine research is relatively new, insufficient,
or little applied to conservation.
