“…; Sales et al., ). The importance of the sediment structure and habitat complexity of vegetated areas for zoobenthic feeders was also noted by Vaslet, Phillips, France, Feller, and Baldwin (), thus is support to a high abundance of E. argenteus and S. greeleyi in this area. Queiroz and Dias () reported that micromollusks were dominant in the algal beds located in the middle area of the Tubarão estuary.…”

“…Others have also noted that fish diversity is higher in the vegetated areas of estuaries (Nanjo, Kohno, Nakamura, Horinouchi, & Sano, 2014;Pereira et al, 2010), which has often been attributed to the importance of these areas as nurseries for reef fishes (Ventura et al 2016;Sales et al, 2016). The importance of the sediment structure and habitat complexity of vegetated areas for zoobenthic feeders was also noted by Vaslet, Phillips, France, Feller, and Baldwin (2012), thus is support to a high abundance of E. argenteus and S. greeleyi in this area.

Do the shallow‐water habitats of a hypersaline tropical estuary act as nursery grounds for fishes?

Fish assemblages were studied in a hypersaline tropical estuary in Northeastern Brazil. A total of 104 species were collected by beach seine during the dry and rainy seasons of 2012. Two families, Atherinopsidae and Gerreidae, were numerically dominant in all zones of the estuary; juveniles of Atherinella brasiliensis, Eucinostomus argenteus, Lile piquitinga, Ulaema lefroyi, Lutjanus analis and Sphoeroides greeleyi contributed 77% of the total catch. The factors that best explained the fish abundance pattern were salinity and depth, which were related to spatial segregation. Species richness was lowest in the upper zone, an area with high salinity and shallow depth. The distinct roles of structurally different habitats (submerged macrophyte beds and mangrove prop‐roots) and the influence of physicochemical conditions in the middle zone of the estuary may influence taxonomic diversity. The middle zone of the estuary is the one most attractive to juveniles of reef species (Lutjanidae and Serranidae). The fish assemblages are clearly dominated by marine estuarine dependent species, highlighting the importance of the ecosystem as a nursery ground for marine species of the Brazilian coast.

“…Thus, mangroves act more as shelters than feeding grounds. These findings coincide with those of Thimdee et al (2004), Lugendo et al (2007) and Vaslet et al (2012), who showed that mangrove fishes can adopt different feeding behaviors related to mangrove settings (i.e., shoreline mangrove, enclosed mangrove lagoons, and ponds) and prey availability. As mangroves and seagrass beds constitute important ecological fish habitats by acting as either shelters, nurseries or feeding areas, it is of primary importance to preserve these interlinked ecosystems to sustain coastal fisheries.…”

ABSTRACT. Mangroves and seagrass beds represent suitable fish habitats as nurseries or feeding areas. This study was conducted in a Caribbean lagoon to assess the foraging habits of juvenile transient reef fishes in these two habitats. Twelve fish species were sampled in coastal mangroves, an offshore mangrove islet, and a seagrass bed site, and stable isotope analyses were performed on fishes and their prey items. The SIAR mixing model indicated that transient fishes from both mangroves and seagrass beds derived most of their food from seagrass beds and their associated epiphytic community. Only a few species including planktivores (Harengula clupeola, Anchoa lyolepis) and carnivores (Centropomus undecimalis and small specimens of Ocyurus chrysurus) presented depleted carbon values, showing reliance on mangrove prey in their diets. Mangrove-derived organic matter contributed marginally to the diet of transient fishes, which relied more on seagrass food sources. Thus, mangroves seem to function more as refuge than feeding habitats for juvenile transient fishes.Keys words: mangrove, seagrass, fish, stable isotopes, SIAR. RESUMEN.Los manglares y las praderas de pastos marinos son hábitats adecuados para la reproducción y alimentación de peces. En este estudio se evaluaron los hábitos alimentarios de peces arrecifales juveniles que transitan por estos dos tipos de hábitat en una laguna del Caribe. Se recolectaron 12 especies de peces en los manglares costeros, un islote de manglares y un sitio de praderas de pastos marinos, y se realizaron análisis de isótopos estables en los peces y sus presas. El modelo SIAR indicó que los peces transeúntes se alimentaron principalmente de los pastos marinos y su comunidad epifita asociada. Sólo unas cuantas especies incluyendo peces planctívoros (Harengula clupeola, Anchoa lyolepis) y carnívoros (Centropomus undecimalis y pequeños ejemplares de Ocyurus chrysurus) presentaron valores de carbono empobrecidos, lo que indica una dependencia de las presas de manglares para sus dietas. La materia orgánica producida en el manglar contribuyó poco a la dieta de los peces transeúntes, los cuales dependieron más de fuentes provenientes de los pastos marinos. Por lo tanto, los peces juveniles transeúntes usan los manglares más como refugio que como hábitat de alimentación.

“…Soil salinity ranged from 30.0-50.8 ppt. MINWR is separated from the mainland by the Indian River Lagoon (IRL), a 260 km long estuary of depths ranging from 0.5 to 3.0 m over muddy and sandy substrates (Vaslet et al 2012). The tides within the IRL are microtidal, which vary between 0.1 m and 0.7 m (Smith 1987).…”

The climate change-induced expansion of mangroves into salt marshes could significantly alter the carbon (C) storage capacity of coastal wetlands, which have the highest average C storage per land area among unmanaged terrestrial ecosystems. Mangrove range expansion is occurring globally, but little is known about how these rapid climate-driven shifts may alter ecosystem C storage. Here, we quantify current C stocks in ecotonal wetlands across gradients of marsh-to mangrove-dominance, and use unique chronological maps of vegetation cover to estimate C stock changes from 2003 to 2010 in a 567-km 2 wildlife refuge in the mangrove-salt marsh ecotone. We report that over the 7-yr. period, total wetland C stocks increased 22 % due to mangrove encroachment into salt marshes. Newly established mangrove stands stored twice as much C on a per area basis as salt marsh primarily due to differences in aboveground biomass, and mangrove cover increased by 69 % during this short time interval. Wetland C storage within the wildlife refuge increased at a rate of 2.7 Mg C ha −1 yr. −1 , more than doubling the naturally high coastal wetland C sequestration rates. Mangrove expansion could account for a globally significant increase of terrestrial C storage, which may exert a considerable negative feedback on warming.
