Soares, Marcelo Oliveira; Teixeira, Carlos Eduardo Peres; Bezerra, Luis Ernesto Arruda; Rabelo, Emanuelle Fontenele; Castro, Italo Braga

This article presents a synthesis of information about the massive oil spill in Brazil (2019/2020). The event afected 11 states; however, the majority of the oil residue was collected (~ 5380 tons) near nine states (99.8%) in northeastern Brazil. This spill was not the largest in volume (between 5000 m3 and 12,000 m3 ) recorded in tropical oceans, but it was the most extensive (2890 km). This spill develops an ...

Blue Carbon Ecosystems in Brazil: overview and an urgent call for conservation ...

Soares, Marcelo O.; Bezerra, Luis Ernesto Arruda; Copertino, Margareth; Lopes, Beatriz Diniz; Barros, Kcrishna Vilanova de Souza

In this article, we discuss knowledge and gaps regarding blue carbon ecosystems (BCEs) in Brazil, considering the urgency to apply protection actions and policies to safeguard their biodiversity and associated ecosystem services. We also indicate areas of further research to improve carbon stocks and sequestration rate estimates. We call attention to the shortage of studies on Brazilian BCEs relative to the gro...

Molecular evidences confirm the taxonomic separation of two sympatric congeneri...

Barroso, Cristiane Xerez; Freitas, João Eduardo Pereira de; Cascon, Helena Matthews; Bezerra, Luis Ernesto Arruda; Lotufo, Tito Monteiro da Cruz

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 Neritina in the Brazilian Province: Neritina zebra (Bruguière, 1792), Neritina virginea (Linnaeus, 1758), and Neritina meleagris Lamarck, 1822. While N. zebra has a well...

Aboveground carbon stock in a restored neotropical mangrove: influence of manag...

Ferreira, Alexander C.; Bezerra, Luis Ernesto Arruda; Cascon, Helena Matthews

Mangrove forests are important sinks of atmospheric carbon, and the internal deposits and fluxes of organic matter can reflect how these ecosystems respond to disturbances and environmental changes. Data on carbon content of mangrove forests vary geographically due to differences in abiotic (climate, geomorphic settings, tides) and biotic (diversity, herbivory, bioturbation) conditions. Mangroves have been degr...

Population and reproductive biology of the fiddler crab Uca thayeri Rathbun, 19...

Bezerra, Luis Ernesto Arruda; Cascon, Helena Matthews

Population and reproductive biology of Uca thayeri Rathbun, 1900 were studied for the first time in a tropical mangrove. Absolute density, sex ratio, population structure, handedness, breeding season and fecundity were investigated. Seven transects were delimited in a mangrove area of the Pacoti River, Northeast of Brazil (3 430 0200 S/38 320 3500 W). On each transect, ten 0.25 m2 squares were sampled on a mont...

Bezerra, Luis Ernesto Arruda; Matthews-Cascon, Helena

The population structure of the fiddler crab U. leptodactyla Rathbun, 1898 was investigated during a one-year period in a tropical mangrove forest in Northeast Brazil (3o 43'S, 38o 32'W). The study specifically addressed factors such as absolute density, sex ratio, population structure and handedness. Eight transects were delimited in a mangrove area of Pacoti River. Monthly, two transects were randomly selecte...

Bezerra, Luis Ernesto Arruda; Dias, Carolina Braga; Santana, Givanildo Ximenes; Matthews-Cascon, Helena

The influence of abiotic factors on the spatial distribution of the fiddler crabs Uca leptodactyla, U. maracoani,U. rapax and U. thayeri was studied in a tropical mangrove of northeast Brazil. Eight transects were delimited in a mangrovearea of the Pacoti River. On each transect, three 0.25 m2squares were sampled during spring low tide periods from September2003 to August 2004. The sediment of the squares at ea...

Ribeiro, Felipe Bezerra; Matthews-Cascon, Helena; Bezerra, Luis Ernesto Arruda

The size at sexual maturity and the allometric growth of the semi-terrestrial crab Sesarma rectum were studied in an impacted tropical mangrove in northeast Brazil. Crabs were monthly collected during spring low-tide periods, from October 2009 through September 2010. A catch-per-unit-effort (CPUE) technique was used to sample the crab population, with two-hour sampling periods, by two people. A total of 492 cra...

Albuquerque, Débora Lucatelli; Ahyong, Shane T.; Bezerra, Luis Ernesto Arruda; Santos, Paulo Jorge Parreira dos

A new species of eurysquilloid stomatopod, Eurysquilla petronioi sp. nov., is described from the tropical western Atlantic. Eurysquilla petronioi sp. nov. is the fourteenth species of the genus to be recognized worldwide, the fifth species from the western Atlantic and the second from Brazilian waters. It is most closely related to E. maiaguesensis from Puerto Rico, but differs chiefly in having an unarmed vers...
