“…The soft-sediment communities of Manukau Harbour have been previously described (Powell, 1937;Grange, 1977Grange, , 1979Henriques, 1980;Grange, 1982;Roper et al, 1988). Time-series data demonstrate that macrofaunal communities have been remarkably persistent over recent years (Turner et al, 1995).…”

“…The loss of these intertidal areas, due to the constant demands of human activities in coastal areas, is a globalscale problem (ROPER et al, 1988;BOER;PRINS, 2002;MARTINHO et al, 2007;TSE et al, 2008;FRANÇA et al, 2012). On tidal mudflats, fish find refuge near the coast; thus, these habitats are considered to be additional recruitment areas that are essential for the life cycle of these fish species.…”

Trophic relationships among fish assemblages on a mudflat within a Brazilian Marine protected areaThe present study deals with the temporal variations in diet and the trophic guilds of dominant fish species on a tidal mudflat during the dry and rainy seasons. We sought to classify the diet composition of 17 species in the Mamanguape river estuary, northeastern Brazil, identifying the dominant food components and evaluating the effects of seasonality on the guild organization. Diets varied little between species and seasons, though they seemed to be more heterogeneous during the rainy season. Five primary feeding guilds were identified, in accordance with the importance of prey in the diets: (1) Detritivore, (2) Zooplanktivore, (3) Zoobenthivore-epifaune, (4) Zoobenthivore-infaune, and (5) Piscivore. Most fishes fed on a diverse range of food items but relied heavily on zooplankton prey. Several fish species showed a tendency to a specialised diet, with almost all species showing some degree of opportunistic feeding. A high degree of diet overlap was found among some species; however, the presence of exploitative competition could not be determined. AbstrActZooplanctívora, (3) Zoobentívora-epifauna, (4) Zoobentívora-infauna, e (5) Piscivora. A maioria dos peixes predou uma variada gama de itens alimentares, mas fortemente baseados em presas do zooplâncton. Alguns peixes apresentaram tendência para uma dieta especializada, com quase todas as espécies mostrando algum grau de alimentação oportunista. Um alto grau de sobreposição de dieta foi encontrado entre as espécies; no entanto, a ocorrência de competição por exploração não foi observada. resumoDescritores: Dieta, Ecologia alimentar, Comunidades de peixes, Sobreposição alimentar, Estuário.

“…The main agents for bioturbation are the crabs Helice crassa and Macrophthalmus hirtipes which are widespread throughout the inlet (Roper et al 1988). Because of the strong bioturbation, the cores had a marked 3-dimensional redox structure, as described elsewhere (Williamson et al 1994).…”

Diagenesis and its effects on the partitioning of trace metals was examined in intertidal muddy sediments in polluted Mangere Inlet, Manukau Harbour, New Zealand. Two cores were sectioned down to 26 cm, and analysed for compounds of Fe, Mn, S, and organic matter. Trace metals were analysed by sequential extraction (nonresidual metals), 0.5M HCl, and XRF (total metals). The sediments were bioturbated, with strong mottling of sediment colour in both cores and intact macropores in one core. Bioturbation appeared to affect sediment chemistry and to cause differences between the cores. There were changes in trace metal partitioning in the non-residual phases with depth, but the changes were relatively small, in line with the changes in major sediment phases. None of the trace metals showed an increase in the lithogenic fraction with depth and we concluded that immobilisation of trace metals by incorporation into residual phases is not an important mechanism in the surface sediments.
