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.

In order to analyze the time-space variation of the fish fauna in the surf zone fish communities at Ilha do Cardoso State Park, São Paulo, Brazil, four consecutive hauls were done over a year on three beaches with different degrees of exposure, at low and high tide. To evaluate the influence of each abiotic variable over the fish community, a Canonical Correspondence Analysis was conducted. We identified 7,286 individuals belonging to 20 families and 47 species, most specimens collected were juveniles. At low tide, the highest diversity and richness values were calculated while the highest dominance was obtained at high tide. As for the number of species collected at the three beaches, stood out for the lower values the cooler months, between June and September. Abiotic variables explained 41.3% of the variability of biological data, where 11.4% corresponds to the spatial variation. Meanwhile the temporal variables accounted for 31.9% of the variation in abundance, where 26.3% of the variance explained nycthemeral variation. Additionally two groups were clearly observed between months with low and high temperature. However in this variable, the tidal variation, excluding the seasonal effect, explained 6.2%, while seasonality, excluding tide effect, explained 26.3%. Although the main measurable seasonal changes were related to temperature, water temperature showed a low percentage of explanation in the fish fauna variability (2.7%). Finally, it is emphasized that the seasonal changes in surf zone fish community primarily reflect patterns of recruitment determined by the reproductive activity and coastal circulation.

Studies accounting the ichthyofauna composition of the Santos-São Vincente estuary-bay and Bertioga channel complex (SSEBBC) are scarce, even with its high ecological and economical importance. In this sense, the present study performed a checklist of the ichthyofauna from the SSEBBC aiming to report the distribution, diet, habitat, economic importance, and conservation status of the collected fish species. Twenty-four (24) monthly collecting campaigns were conducted between March 2013 and February 2015. In each survey, four locations around Bagres Island were sampled with the aid of gill nets with standardized effort. Dead fish specimens were also collected during the accidental fire that occurs on the Terminal Químico de Aratú S.A. (TEQUIMAR) between April 2nd and 10th of 2015. A total of 172 fish specimens were collected, where 50.6% were carnivorous; 35.5% were marine-estuarine; 44.2% with high occidental Atlantic Ocean distribution; 44.8% were a high important food resource. Regarding the conservation status, these fish species were classified as “low-worries” in 76.2% for the global evaluation; 95.3% in national evaluation; and 55.2% in São Paulo State evaluation. Moreover, 53 new fish species were catalogued for the Santos-São Vincente estuary-bay, where 12 were collected during the field monitoring and 41 during the fire monitoring. Fifty-eight (58) fish species collected during the field campaigns were categorized like “insufficient data”; 3 as alien species (Oreochromis niloticus, Opsanus beta e Butis koilomatodon); and there was a rare record of Megalops atlanticus in São Paulo State. Besides of the high anthropization, the studied area presented high fish species richness and should be monitored to ensure the fish species conservation status.

ABSTRACT The marine crab Xanthodius parvulus (Fabricius, 1793) is naturally distributed in the Western Atlantic, being commonly found in the northeastern Brazilian coast. However, this species has been also recorded in the southeastern coast, especially in São Paulo State, on islands located close to harbors, which are becoming a place of occurrence for exotic species. This study aimed to estimate the morphological sexual maturity (relative growth) of X. parvulus the functional biological patterns of the species in a No-take marine reserve. The crabs were sampled at the Marine State Park of Laje de Santos, an important protected area from São Paulo that is located close to the largest Brazilian harbor, Santos, using an artificial substrate and active search methods (scuba diving). The morphological sexual maturity of females was estimated in 7.28 mm, according to the Abdomen Width vs. Carapace Width relationship, while for males this value was 8.83 mm based on the Gonopod Length vs. Carapace Width relationship, the females presented an increase in abdominal growth, even during the mature stage in order to achieve higher reproductive success, since the abdominal structure is used to protect the embryos. The Gonopod Length vs. Carapace Width relationship showed that males copulate with different sized females, since a non-exaggerated growth of the gonopods keeps them adequate to the size of the female genital pore, i.e., juveniles exhibited negative allometry and adults presented isometry. Thus, estimating the size of the sexual maturity of a species requires the development of a model to acknowledge its biological and reproductive pattern, being an important tool to increase the knowledge about the behavior of this species and one of the parameters to evaluate its conservation status.

AbstractThe knowledge of biotic and abiotic drivers that put non-native invasive fishes at a disadvantage to native ones is necessary for suppressing invasions, but the knowledge is scarce, particularly when abiotic changes are fast. In this study, we increased this knowledge by an analysis of the biomass of most harmful Prussian carp Carassius gibelio in a river reviving from biological degradation. The species' invasion followed by the invasion's reversal occurred over only two decades and were documented by frequent monitoring of fish biomass and water quality. An initial moderate improvement in water quality was an environmental filter that enabled Prussian carp’s invasion but prevented the expansion of other species. A later substantial improvement stimulated native species’ colonization of the river, and made one rheophil, ide Leuciscus idus, a significant Prussian carp’s replacer. The redundancy analysis (RDA) of the dependence of changes in the biomass of fish species on water quality factors indicated that Prussian carp and ide responded in a significantly opposite way to changes in water quality in the river over the study period. However, the dependence of Prussian carp biomass on ide biomass, as indicated by regression analysis and analysis of species traits, suggests that the ecomorphological similarity of both species might have produced interference competition that contributed to Prussian carp’s decline.

Abstract 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.

Bird Richness

Bird species richness is an important measure for monitoring biodiversity changes. We analysed avifauna richness and composition in a 472 ha protected cerrado fragment and surroundings at Fazenda Canchim (RL-CPPSE), São Carlos, in the State of São Paulo (SP). We carried out 95.1 hours of observation (22 visits) at irregular intervals from May 2004 to December 2006. Qualitative surveys were done walking through tracks inside the fragment and on the roads at its edge. We recorded 160 species, six of which were endemic to Cerrado domain, 22 migratory, seven threatened within the State of São Paulo, and two globally threatened. We found 28 species in the cerradão, 110 in the cerrado sensu stricto, 13 in the gallery forest, 26 in the reservoir border, 26 in pasturelands and sugar cane monoculture and 55 in an anthropic area. Most of the species had low frequency of occurrence in all vegetation forms. Insectivores were the major trophic category (46.9%), which is typical in tropical regions, and it is also related to resource availability. Omnivores followed with 19.4%, granivores with 8.8% and frugivores with 7.5%. We conclude that, despite its size and conservation status, our study area has a remarkable bird community and must be considered as a priority conservation area to preserve bird species in Sao Paulo State.
