Description
1. Introduction The activities of modern human society have driven the most dramatic and unprecedented mass extinction event on earth, with the current rates of global species loss exceeding 1,000 times those observed from fossil records (Millennium Ecosystem Assessment, 2005). Among regions, the majority of extinctions are occurring in the tropics, the regions of the highest biodiversity. Among ecosystem types, inland aquatic systems are arguably the most impacted because human reliance on freshwater leads to a concentration of human activities on these systems (Ricciardi and Rasmussen, 1999; Sala et al., 2000). This scenario suggests that Neotropical coastal lagoons (hereafter called NCLs for brevity), whose continental coastline distributions coincide with densely-populated areas in the Neotropics, are probably among the most human-dominated and threatened ecosystems on earth (Berkes and Seixas, 2005). This fact, along with the concern that coastal lagoons are valuable and representative components ([approximately equal to] 12.2% South America coastline) of coastal areas in terms of both ecosystem and natural capital (Gonenc and Wolflin, 2004), indicates that NCLs should be a priority among the conservation planning of natural ecosystems in Neotropical countries (Esteves et al., 2002; Barbosa et al., 2004).
