Última Diel density variation of amphipods associated with Sargassum beds from two shores of Ubatuba, Southeastern, Brazil Iheringia, Sér. Zool. Leite,Fosca P. P.; Tanaka,Marcel O.; Sudatti,Daniela B.; Gebara,Raquel S.. Densities of mobile epifaunal assemblages associated with macrophytes are very variable during the day and the activity of visually-oriented predators is thought to have an important influence on this pattern. Here we compared densities of amphipods associated with a common brown alga, Sargassum stenophyllum (Phaeophyceae), at sites contrasting in water turbidity. We expected that diel variation of amphipods would occur in a shore with clear waters (Perequê), whereas no variation was expected in a shore with turbid waters (Lamberto). Amphipod density varied during the day at both shores, with no indication of a larger variation at Perequê. Most species showed two density peaks, one at night and the other in the afternoon. These peaks occurred close the... Tipo: Info:eu-repo/semantics/article Palavras-chave: Diel variation; Amphipods; Sargassum.
