Blue carbon stock heterogeneity in Brazilian mangrove forests: A systematic review.

This is the first systematic review and meta-analysis of blue carbon stocks in Brazilian mangroves. We evaluated the effect of characteristics and site status (impacted versus non-impacted) on carbon stocks found in the various compartments on total ecosystem carbon stock (TECS). TECS followed an inverse trend with the latitudinal position: the highest values were found on the North coast (mean 511 Mg C ha), followed by the Northeast and Southeast.

Historical land use changes lead to massive loss of soil carbon stocks in a recovering, semiarid mangrove.

Land use changes lead to substantial releases of carbon from the soil into the atmosphere. In carbon-rich ecosystems, like mangrove forests, this carbon loss may be more intense. This study evaluated soil carbon stocks in a mangrove area historically impacted by salt farming, which is under ecosystem recovery, in the semiarid coast of Northeastern Brazil.

Lessons from the invasion front: Integration of research and management of the lionfish invasion in Brazil.

After successful invasions in the Caribbean and Mediterranean, lionfish (Pterois spp.) have recently invaded another important biogeographical region -the Brazilian Province. In this article, we discuss this new invasion, focusing on a roadmap for urgent mitigation of the problem, as well as focused research and management strategies.

The most extensive oil spill registered in tropical oceans (Brazil): the balance sheet of a disaster.

This article presents a synthesis of information about the massive oil spill in Brazil (2019/2020). The event affected 11 states; however, the majority of the oil residue was collected (~ 5380 tons) near nine states (99.8%) in northeastern Brazil.

Alien hotspot: Benthic marine species introduced in the Brazilian semiarid coast.

In this study, we provide a baseline assessment of introduced marine species along the extensive (~600 km) Brazilian semiarid coast. We reported 27 introduced and 26 cryptogenic species. Moreover, the main vectors of introduction were ballast water, shipping lines, oil and gas activities, biofouling, and rafting on plastic debris.

Marine debris from the past - Contamination of the Brazilian shore by a WWII wreck.

In 2018, unidentified packages appeared along approximately 1600 Km of the Brazilian coastline causing widespread pollution to beaches and danger to society. The packages were found to be bales of raw rubber ranging in size from 0.06 m³ to 3.

Molecular evidences confirm the taxonomic separation of two sympatric congeneric species (Mollusca, Gastropoda, Neritidae, ).

A reliable taxonomy, together with more accurate knowledge of the geographical distribution of species, is a fundamental element for the study of biodiversity. Multiple studies on the gastropod family Neritidae record three species of the genus in the Brazilian Province: (Bruguière, 1792), (Linnaeus, 1758), and Lamarck, 1822. While has a well-established taxonomic status and geographical distribution, the same cannot be said regarding its congeners.

Marine benthic communities affected by the Doce River (southwestern Atlantic): Baseline before a mining disaster.

Prior to Brazil's worst environmental disaster, caused by a mining dam collapse, we had carried out a study of the marine benthic macrofauna (11-51 m depth) under the influence of the Doce River. Our results showed significant diversity, in which mollusks, polychaetes, and crustaceans had the highest frequency, density, and abundance, represented by 162 families in summer and 173 in winter. Our results suggested that richness, abundance, and diversity increase with distance from the coast.
