“…Marked seasonal changes in fish assembalge structures have also been detected in previous studies from mangrove ecosystems (Hindell and Jenkin, 2004;Lin and Shao, 1999;Newman et al, 2007;Tommaso and Krumme, 2009). The species richness and total abundance increased from spring, and reached peak in summer and in fall (Table 4), which might be productive traits of fish caused.…”

The composition and temporal variation of fish assemblages were investigated in the mangrove of Qinzhou Harbor, Guangxi Province, China from October 2011 to September 2012. A total of 67 fish species belonging to 57 genera, 32 families and 12 orders were collected. The Gobiidae (23.9%) were the most species-rich families, and the dominant species were Acentrogobius viridipunctatus and Bostrychus sinensis. Species richness, total abundance, total biomass and individual species abundance or biomass for the numerically abundant fish species were significantly different seasonally, such as abundance and biomass for A. viridipunctatus, B. sinensis, Glossogobius giuris, Acanthogobius hasta, Gerres limbatus, Sillago sihama, Lateolabrax japonicas, Moolgarda cunnesius and Leiognathus brevirostris. The Non-metricMultidimensional Scalings (NMDS) ordination showed a clear separation of fish samples with an anticlockwise direction for different sampling months, which indicated a gradual change in fish assemblages over the months. Results of two-way ANOVA showed fish species richness, total abundance and total biomass were significantly affected by tidal type in the mangrove of Qinzhou Harbor. However, NMDS ordination showed an unclear separation of fish samples between spring tide and neap tide. One-way ANOSIM further revealed no significant effects of tidal type.

“…Fish were assigned to 3 size classes: TL < 12 cm (small), 12 ≤ TL <18 cm (medium), TL ≥ 18 cm (large). Recruitment of C. psittacus occurs continuously (Giarrizzo & Krumme 2009) so that the gonads are small and difficult to identify (T. Giarrizzo pers. obs.…”

Tidal migrations of fishes are influenced by several coincident factors (abiotic and biotic). The interactive effect of these multiple factors has never been analyzed statistically in a model approach. We used proportional hazards analysis to analyze the interactive effect of space (4 creeks) and time (diurnal neap tide cycles in 2 seasons) on patterns in the intertidal migration of 3 size classes of the banded puffer fish Colomesus psittacus (Tetraodontidae) from mangrove creeks and link this to ontogenetic and temporal changes in feeding. The intertidal migration strategy and patterns of vertical resource exploitation changed ontogenetically, thereby reducing intraspecific competition. Juvenile fish entered creeks earlier and left later, which resulted in longer feeding times and fuller intestines than adults. Juveniles fed mainly on barnacles and fiddler crabs from the mid-intertidal, while adults were specialized predators of the mangrove crab Ucides cordatus from the high intertidal. The shape of the migration curves (the proportions of fish leaving a creek at a given ebb tide water level) indicated that the tidal migration took place in close response to creek-specific drainage characteristics and suggests that the fish interact successfully with variable and dynamic creek features in a macrotidal mangrove environment. When ebb tide cycles were completed during daylight hours, the tidal migration was well-structured. When ebb tide overlapped with sunset, juveniles left earlier, and the tidal migration was compressed. We provide a time budget scenario of habitat use by diurnal C. psittacus during a 15 d spring-neap tide cycle according to the changes in interactions of flood and ebb tide with sunset and sunrise.

Differences in intertidal appearance of species or size classes may be linked to differences in the distance between the lowwater (LW) resting site and the high-water (HW) feeding sites (Kneib 1995, Kneib & Wagner 1994. A study in a natural US salt marsh creek revealed that tidal migrations of fishes are structured both inter-and intraspecifically (Bretsch & Allen 2006a). Experiments conducted in a constructed pumped seawater system which was used to mimic a section of intertidal salt marsh creek showed that the non-random tidal migration pattern in prey species is influenced by the presence of their predators (Bretsch & Allen 2006b).Several factors, both abiotic and biotic, can influence the tidal migrations of fishes. A factor can ac...

“…Mangroves of Maranhão, for example, might disappear altogether if the flow of freshwater dominates the tidal prism, causing the replacement of mangrove species by macrophytes (Lacerda et al, 2002). Many fish use the mangroves directly for at least some period of their life cycle, or might indirectly rely on resources derived from it (Giarrizzo and Krumme, 2009). The replacement of brackish water by freshwater in these environments will cause the elimination of a very important habitat for many species of fish, crustaceans and molluscs, and the probable loss of mangrove species (Mumby et al, 2004).…”

Wetlands cover approximately 6% of the Earth´s surface. They are frequently found at the interface between terrestrial and aquatic ecosystems and are strongly dependent on the water cycle. For this reason, wetlands are extremely vulnerable to the effects of climate change. Mangroves and floodplain ecosystems are some of the most important environments for the Amazonian population, as a source of proteins and income, and are thus the types of wetlands chosen for this review. Some of the main consequences that can be predicted from climate change for wetlands are modifications in hydrological regimes, which can cause intense droughts or inundations. A possible reduction in rainfall can cause a decrease of the areas of mangroves and floodplains, with a consequent decline in their species numbers. Conversely, an increase in rainfall would probably cause the substitution of plant species, which would not be able to survive under new conditions for a long period. An elevation in water temperature on the floodplains would cause an increase in frequency and duration of hypoxic or anoxic episodes, which might further lead to a reduction in growth rates or the reproductive success of many species. In mangroves, an increase in water temperature would influence the sea level, causing losses of these environments through coastal erosion processes. Therefore, climate change will likely cause the loss of, or reduction in, Amazonian wetlands and will challenge the adaptability of species, composition and distribution, which will probably have consequences for the human population that depend on them.Keywords: global warming, wetlands, mangrove, floodplains, Amazonia. Possíveis impactos das mudanças climáticas em áreas úmidase sua biota na Amazônia brasileira ResumoAs áreas úmidas cobrem aproximadamente 6% da superfície da terra e são frequentemente encontradas na interface entre ecossistemas terrestres e aquáticos e fortemente dependentes do ciclo da água. Por esta razão são extremamente vulneráveis aos efeitos das alterações do clima. Os ecossistemas de manguezais e várzeas são muito importantes para os seres humanos da Amazônia, porque são de onde eles extraem algumas das principais fontes de proteínas e renda, e, por isso, foram os dois tipos de áreas úmidas escolhidos para esse estudo. Entre as principais consequências das mudanças climáticas previstas para esses ambientes estão as alterações nos regimes hidrológicos, que podem causar grandes secas ou inundações. A possível redução das chuvas pode causar a diminuição das áreas de mangue e várzea, provocando um rápido declínio de suas espécies. Por outro lado, o aumento das chuvas teria como provável consequência a substituição de espécies de plantas, que não seriam capazes de sobreviver sob as novas condições por um longo período de tempo. As principais consequências do aumento da temperatura da água entre as áreas úmidas seria que nas várzeas este parâmetro aumentaria a frequência ou duração dos episódios hipóxicos e/ou anóxicos, podendo causar a redução da taxa de...
