“…They considered organic matter, however, as amorphous material, non-differentiated or non-quantifiable, composed of macroalgae, microalgae, sessile organisms and detritus, and once again, the real proportion of each of those categories was not measured. In contrast with these studies that classified S. cristata as a herbivorous blenny, Tararam & Wakabara (1982) identified a large amount of invertebrates in the gut content of S. cristata from tidepools along the coast of São Paulo (the south-eastern Brazilian coast). A number of observations of S. cristata have been made from fish corpses in tide pools and in the subtidal environment of Arraial do Cabo rocky shores (T. C. Mendes & C. E. L. Ferreira, pers.…”

“…Scartella cristata is a conspicuous inhabitant of shallow rocky systems and tide pools, and is considered to feed mostly on EAM (Randall, 1967). Although some studies have tried to characterise its diet (Randall, 1967; Tararam & Wakabara, 1982; Nieder, 1997; Mobley & Fleeger, 1999), none has previously dealt successfully with spatial or temporal variations or even described its feeding rate pattern. The goals of the present study were two‐fold: (1) to investigate the seasonal variation of feeding rates of S. cristata and (2) to analyse spatial and seasonal variations in its diet.…”

The goals of the present study were to investigate the feeding rates of Scartella cristata, accounting for different water temperature regimes, and to analyse spatial and seasonal variations in its diet. The feeding rate of S. cristata was higher in warmer waters and was not correlated with season. A typical herbivorous diel feeding pattern was observed, with a steady increase in bite rate throughout the morning until a plateau in the early afternoon, followed by an abrupt decrease until the end of the daylight period. The gut contents of S. cristata included at least 41 different items. Detritus and algae (mainly filamentous) comprised most of the bulk of S. cristata's diet. Scartella cristata also exhibited significant seasonal and spatial variability in its diet. This study highlights the importance of detritus within the epilithic algal matrix in the diet of S. cristata and pinpoints that, as in coral reefs, the detrital pathway exerts an important role in the trophodynamics of subtropical rocky shores where these fish are abundant.

“…Biology and autoecology of Gammaridea also started at this time (Leite, 1976;Tararam, 1980). In the last decade, 1981-1989, important papers were published on Gammaridean taxonomy (Valerio-Berardo, 1986; J. L. Barnard & Thomas, 1988a, b;Wakabara et al, 1988), biology of Gammaridea (Leite & Wakabara, 1989), Amphipoda as fish prey (Wakabara etal., 1982;Tararam & Wakabara, 1982;Ribeiro, 1982), biology of Caprellidea (Takeda, 1981;Masunari & Dubiaski-Silva, 1988) and ecology of Gammaridea (Tararam & Wakabara, 1981;Tararam etal., 1986;Jacobi, 1987) Presently, we are examining only the data of amphipod specimens that we have already identified, and so far we can verify this amphipod fauna comprises 83 species belonging to 59 genera.…”
