“…They are estuarine-dependent species and live in sandy or muddy bottom. Both are carnivorous with preference for benthic organisms, feeding on crustaceans, bivalve siphons, and polychaetes (Pattillo et al 1997; Denadai et al 2015).…”

Archaeological Earthen Mound Complex in Patos Lagoon, Southern Brazil: Chronological Model and Freshwater Influence

et al. 2017

In the present work, we assess the chronology of archaeological sites known as earthen mounds, commonly found at the Pampas biome, among the lowlands of Brazil, Uruguay, and Argentina. We focused on the Pontal da Barra settlement, which is a testimony of the long-term occupation of indigenous groups in the swamp and wet environment of Patos Lagoon, southern Brazil. A Bayesian chronological model based on the radiocarbon (14C) dating of 17 samples of fish otolith, 5 charcoal fragments, and 2 bones (human and dog) allowed determination of the beginning of the occupation as well as the occupational synchronism of the different mounds. The nature of the samples allows us to study the local 14C reservoir effect through the comparison between the group of marine and terrestrial samples, deriving a reservoir offset value of 63±53 14C yr for this particular area, indicating a strong freshwater influence in the lagoon system. We estimate the start of human intervention in the landscapes of southern Patos Lagoon to be around 2200 cal BP, with the most intense activity between 1800 and 1200 cal BP.

Trophic ecology of two syntopic sciaenid species (Micropogonias furnieri (Desmarest, 1823) and Ctenosciaena gracilicirrhus ) (Metzelaar, 1919) in a tropical bay in south-eastern Brazil

Summary Analyzed were the diets of two closely related species of Sciaenidae (Micropogonias furnieri and Ctenosciena gracilicirrhus) coexisting in high abundance in the outer zone of Sepetiba Bay. Their sizes and seasonal niche dimensions were also analysed. The tested hypothesis was that these two abundant species do not overlap in the trophic niche despite occurring in the same area and having similar sizes and body shapes and where an intraspecific overlap is likely to occur. The stomach contents of 198 M. furnieri specimens (85–280 mm total length) and 198 C. gracilicirrhus (49–131 mm total length) were examined. Quarterly diurnal fish samplings were performed using bottom trawls between winter 2012 and autumn 2013. In each season, three replicate tows were taken against the current during 20 min at the bottom with a towing speed of circa 4.5 km/hr, covering a distance of approximately 1,500 m. The trawl had an 8 m headline, 11 m ground rope, 25 mm stretched mesh and 12 mm mesh cod‐end liner. Significant differences were detected in the diet between the two species (Pseudo‐F = 5.16; p = .001) and among size classes (Pseudo‐F = 2.23; p = .001), but not among seasons (Pseudo‐F = 0.36; p = .920), according to PERMANOVA. Micropogonias furnieri fed mainly on Polychaeta and Caprella, whereas C. gracilicirrhus fed preferably on Caprella. Both species tended to specialize as they grew in size, with M. furnieri preferring Polychaeta, and C. gracilicirrhus specializing in Caprella. As expected, a high intraspecific niche overlap was observed among the size classes within each species, but not at an interspecific level and with the two syntopic species using different feeding resources.

“…This seasonal fish spawns mainly at the bottom salinity front of the estuary, in the inner region, and is commonly found in the summer when it migrates for breeding (Militelli et al 2013). It is carnivorous, with preference for benthic organisms, feeding on crustaceans, mollusks, and polychaetes (Patillo et al 1997; Denadai et al 2015).…”

The Marine Reservoir Effect on the Coast of Rio de Janeiro: Deriving ∆R Values from Fish Otoliths and Mollusk Shells

et al. 2018

Considering the impact of coastal dynamics on the radiocarbon (14C) marine reservoir effect (MRE), upwelling has the potential of enhancing marine influence, usually14C depleted. Freshwater input can contribute either to increased reservoir offsets, when dead carbon from rock weathering is available, but also towards an atmospheric14C signal, when the presence of terrestrial organic matter from catchment prevails. An overview of the MRE studies based on shellmounds on the coast of Rio de Janeiro reveals a pattern of negative local corrections for Saquarema and Rio das Ostras but positive values for Cabo Frio island, suggesting the presence of cold upwelling waters in Cabo Frio at 1.6–1.2 cal kBP. New results for a shellmound on the Ilha Grande island, in the western portion of the Rio de Janeiro coast, revealed a negative value at about 3 ka. We discuss distribution of MRE values and temporal variability in the region and their relation to ocean dynamics, continental input and the choice of marine organisms used for ∆R determination. A comparison of local reservoir offsets for the Saquarema region obtained from fish otolith and mollusk shells revealed similar ΔR distributions, showing that both materials can be equally used.
