Escalas de variação de comunidades bentônicas de infralitoral em ilhas pertencentes a uma área de proteção ambiental no Sudeste do Brasil: reflexões sobre processos estruturadores e subsídios para monitoramento

“…Also, it was pointed out that, along rocky shores in the SE Brazil, the total number of species found in other studies, was between 32 and 70. Thus, those communities were characterized by few dominant species, which accounted for most of the cover alone (Ghilardi, 2007), as observed in the present work. Hereby, the highest number of dominant species was seven, in the shallower community, in the winter.…”

“…Although direct comparison of this group with documented species was not possible, it has already been observed by other studies in the region under the same classification (Széchy & Paula, 2000;Ghilardi, 2007).…”

“…The total number of biological units that could be discriminated in the photographs was 29, as expected, according to other descriptive studies. Ghilardi (2007), in the MPA of Anchieta Island, Ubatuba, found 29 dominant species on the subtidal benthic community. Also, it was pointed out that, along rocky shores in the SE Brazil, the total number of species found in other studies, was between 32 and 70.…”

“…Furthermore, many descriptive studies have been undertaken in SE Brazil, thereby providing clues about what kind of community could be expected. This region was found to have been structured by macroalgae, in particular Sargassum spp., as well as Articulated Calcareous Algae (Eston et al, 1986, Figueiredo et al, 1994, Széchy & Paula, 2000, Amado Filho et al, 2006, Ghilardi, 2007, so these were expected to be found in abundance.…”

“…In the Southeastern Brazil Ecoregion (Spalding et al, 2007) data regarding benthic communities of Insular Marine Protected Areas is very scarce (but see Amado Filho et al, 2006 andGhilardi, 2007). The most limiting factors responsible for the small number of sampled area seems to be the methodologies applied, the difficulties inherent to working in the marine environment, and the need for students, researchers and technicians, capacitated in the field, particularly in the subtidal zone, the least studied region (Berchez et al, 2005).…”
