Comparative study of the estimated sample size for benthic intertidal species and communities
The objective of this study was to determine the minimum sample size for studies of community structure and/or dominant species at different heights of a rocky intertidal zone at Rio de Janeiro. Community structure indicators suggested a variation in the minimum surface of 100 to 800 cm , with a min...

The objective of this study was to determine the minimum sample size for studies of community structure and/or dominant species at different heights of a rocky intertidal zone at Rio de Janeiro.

Indicators of species abundance suggest 100 cm for Hypnea musciformis and 400 cm for Ulva fasciata, Phragmatopoma lapidosa Kinberg, (1867) and Gymnogongrus griffthsiae at lower heights; 200 cm² for Chthamalus spp. at intermedíate heights; and 800 cm for Littorina ziczac at the greatest height.
