First-time observations of courtship behavior the endangered Sicklefin Devil Ray (Mobula tarapacana) are described in a Marine Protected Area - MPA (ESEC Tamoios / ICMBio) and Exclusion Zone Oil Terminal (TEBIG Petrobras Transporte S.A. TRANSPETRO) Southwestern Atlantic, both from Ilha Grande Bay. M. tarapacana was recorded at two different times (2 couples 1 male female) October November 2024 used professional camera unmanned aerial vehicles (UAV; drone) , which this study highlights...

The Brazilian coast, especially Rio de Janeiro, is vital as a migratory corridor, nursery, and refuge for 113 elasmobranch species, including 68 sharks. Advances in conservation technologies, such satellite-linked transmitters with Unmanned Aerial Vehicles (UAVs) approach, are crucial monitoring species remote, hard-to-reach habitats. This study aimed to provide preliminary insights into the movement patterns of multiple shark using satellite telemetry UAV-assisted monitoring, well document...

Samples were collected from 10 stations distributed through three sectors in Guanabara Bay during two consecutive years, order to determine factors that influence the spatial pattern of molluscs and describe structure composition this community a eutrophic estuarine system on Brazilian coast. Although only one species, gastropod Heleobia australis , comprised 77% mollusc abundance, 59 species identified bay. In addition H. other dominant: Anachis isabellei bivalves Americuna besnardi Ervilia...

Hydrobiidae is one of the most diverse taxa among limnic and estuarine mollusks. Patterns spatial seasonal distribution Heleobia australis were studied in ten stations over two years, urban eutrophic bay Guanabara, Rio de Janeiro, Brazil. Spatial dispersal strategies adults this species, analyzed laboratory, revealed three patterns: 1) mobility on soft sediments; 2) hard substrata; 3) ability to lift from bottom surface, again sink down. This facilitate species movement location another by...

Spatial and temporal distribution of two species adult´s ostracods (Cyprideis sp. Cyprideis salebrosa) were studied as a function the rainfall patterns in Guanabara Bay, Rio de Janeiro, Brazil. Samples taken ten stations, along six surveys representing three periods (Dry, Early Late Rainy) for years. Stations nested four areas (Outer, Central, EPA Guapimirim Impacted). The bottom water (temperature, salinity, dissolved oxygen saturation) measured each area to characterize influence seasonal...

ABSTRACT Isotopic analysis of Micropogonias furnieri otoliths were used to get insight into palaeoceanographic conditions in the Guanabara Bay and Saquarema Lagoon, Rio de Janeiro state (RJ), located on southeastern coast Brazil, under upwelling influence Cabo Frio system. Archaeological come from two Holocene shellmounds (or sambaquis ): Galeão Beirada. For first time, radiocarbon using high accuracy techniques performed at Galeão. Age range was determined be between 5820 4980 cal BP, which...

Soft-bottom macrobenthic invertebrates are sensitive to natural or anthropogenic changes in aquatic ecosystems. The distribution patterns of sublittoral species Guanabara Bay were studied from 2005 2007. Samples collected at ten stations during six surveys throughout the rainfall regime (dry, early and late rainy). Ten replicates each station by Gravity corer skin diving. Van Dorn bottles (bottom water) Ekman sediment sampler (granulometry) provided material for abiotic data. Stations...
