Summary graph of the variables analyzed for the connectivity representation of Haemulon flavolineatum migratory potential in the Bahía Portete-Kaurrele MPA. The sum of the arrows indicates whether the variables are beneficial (up arrows) or detrimental (down arrows) to the species. Part A summarizes and compares the structural and functional connectivity indices for each ecosystem. This could be interpreted as the quality of the habitat where the juvenile lives (according to the measured indices), as well as the habitat conditions that the juveniles will experience when migrating. The species use all three ecosystems as observed in the field; therefore, in theory, they could fulfill life stages four and five. However, the indices suggested that the reef is a relatively better habitat for the species in the MPA. Part B summarizes and compares the structural and functional connectivity indices of seagrass and mangroves between the bay areas. Note that mangroves are better in the northern zone and worse in the central zone, while seagrasses are better in the south and worse in the north. The migration of H. flavolineatum juveniles is favored mainly in the south. In the scheme, representativeness refers to the coverage (ha) of each ecosystem in each zone of the bay, and fragmentation is the relation between coverage and the number of patches. Asterisks refer to significant differences
