“…The bay is limited by rocky flanks and bordered by four beaches. The sediment composition ranges from dense silt to medium sand, and from very poorly to poorly sorted (Gubitoso et al, 2008). This configuration protects the area from the direct effects of hydrodynamic factors outside the São Sebastião Channel; the hydrodynamics are dominated by the tides, but also feature low-amplitude waves (Amaral et al, 2010).…”

A mangrove forest can harbour several macroalgal assemblages growing on pneumatophores, roots, stems and other hard substrates. These algae belong to various genera, most typically Bostrychia, and form a community called the Bostrychietum. This study describes the fauna associated with the Bostrychietum and the effect of emersion time on the community. Seasonal samples were collected from pneumatophores on an island in Araçá Bay in 2012, in two areas, one on the border of the island and one inland. Each pneumatophore was considered a sample. The border samples, with a shorter emersion time, contained a richer algal flora associated with pneumatophores, and fauna with species of varied dietary habits. The inland samples, with a longer emersion time, contained only two algal genera and fauna species comprised mostly of omnivorous amphipods and desiccation-resistant detritivorous species. Macrofauna diversity and richness varied over time and were lower in spring. Therefore, the emersion time of the Bostrychietum and the period of the year affect the community structure, for both the macroalgae and the associated fauna.

“…3. Two encircling gillnets were deployed; one (590 m long, 3 m high, and 30 mm stretched mesh) was used in the shallow sublittoral with two random and independent deployments; another encircling gillnet (220 m long, 2.6 m hight, and 32 mm stretched mesh) was used in the intertidal, with one deployment at Mãe Isabel creek ( Figure 1), and two deployments in the inner sublittoral, one near the rocky shore located south the islets to the bay's mouth is of 1.16 ± 0.53 m. The bay's configuration prevents it from being directly influenced by the relatively strong SSC hydrodynamics, thus, the main abiotic driver in the bay is the tide (Amaral et al 2010;Gubitoso et al 2008). For our purposes, we divided the bay into three sectors: intertidal, shallow sublittoral and outer sublittoral ( Figure 1).…”

This paper presents for the first time a checklist of the fish fauna of Araça Bay, São Sebastião Channel, northern coast of São Paulo state, Brazil. Fishes were sampled in five surveys from October 2012 to February 2014 using nine different types of sampling gear during high tide. Tide pool fishes were also sampled in four surveys from March to October 2014. Geographic distribution and conservation status of each species are reported. A total of 126 species was recorded in Araçá Bay, including two non-native species and new records in the São Sebastião region for 16 species. The fish species richness found in Araçá Bay was greater than the previously recorded for the São Sebastião Channel and other adjacent areas. Most of the Araçá fish species show a wide distribution along the western Atlantic Ocean (32%). Few species are included in the international (29%) and Brazilian (3.3%) official lists of threatened species.

“…It includes a cove bordered by rocky walls and an extensive coastal plain with soft sand, which impedes the direct effects of tide-based hydrodynamic factors (Amaral et al 2010, Alitto et al 2016). The region is exposed to different types of human activity, including illegal occupation (Zanardi et al 1999), domestic effluents (PLDS/Araçá 2016), underwater dredging (Gubitoso et al 2008, Teodoro et al 2011, PLDS/Araçá 2016, and activities in the nearby Port of São Sebastião (Amaral et al 2010, PLDS/Araçá 2016.…”

Density and diversity of filamentous fungi in the water and sediment of Araçá bay in São Sebastião, São Paulo, Brazil

et al. 2018

Araçá Bay, located in the city of São Sebastião, São Paulo, Brazil, is a protected area of substantial complexity. It represents the last remaining mangrove swamp preserve between the cities of Bertioga and Ubatuba on the northern coast of São Paulo State. This mangrove swamp has specific physical and chemical properties, and it shelters a wide variety of life, including fungi. These microorganisms are present in a variety of species with different morphophysiological features, and they have the ability to produce enzymes of biotechnological importance. The goal of this study was to quantify, isolate, and identify filamentous fungi in water and sediment samples from the Araçá Bay mangrove swamp in São Sebastião. Two samplings were performed in the summer and two were performed in the winter. The samples were collected from intertidal zones, and dissolved oxygen (DO), temperature, salinity, and pH were measured in situ. The spread plate technique was used to inoculate the samples collected on plates with a potato dextrose agar (PDA) medium. A total of 208 colonies (68 from water samples and 140 from sediment samples) were isolated, and they were identified based on their morphological characteristics. Filamentous fungus density was higher in the sediment than in the water, and the samplings performed in the winter revealed a higher density than those performed in the summer. Though some of the environmental parameters were not ideal for fungal development, a high quantity of growth was nevertheless observed. When the isolated colonies were analyzed, the greatest diversity and species richness were found in the summer samples. The genera identified in all of the samples were Aspergillus, Penicillium, Cladosporium, and Fusarium. The pathogenic species found from these genera were Aspergillus fumigatus, A. terreus, Penicillium citrinum, and P. chrysogenum. These species are also able to produce enzymes that offer a variety of applications. The fungal community described herein represents the diversity found in this mangrove swamp during the period studied. Many of the fungus species found are pathogenic and may be useful due to their ability to produce specific enzymes applicable in the biotechnological and pharmaceutical industries.
