Whistles of Atlantic spotted dolphin from a coastal area in the southwestern Atlantic Ocean [PDF]
The Journal of the Acoustical Society of America, 2020 Atlantic spotted dolphins were recorded on the coastal area of Rio de Janeiro with equipment of 192 kHz sampling rate. The animals produced an average of 33 whistles/min. The repertoire was balanced among four contour categories, with the occurrence of a stereotyped whistle. Frequency parameters were measured between 1.3 and 29 kHz, which represents an

Biogeographic and species richness patterns of Gastropoda on the southwestern Atlantic [PDF]
Revista Brasileira de Biologia, 1999 Patterns of richness and biogeography of Gastropoda molluscs were determined based on lists of species from five sites along the southwestern Atlantic. The analysis of the distribution patterns of these sites confirmed the existence of a broader transition zone between southern Espírito Santo State (21°S) and Rio Grande do Sul State (32°S).
