Metagenomic analysis of sediments under seaports influence in the Equatorial At...
Tavares, Tallita Cruz Lopes; Normando, Leonardo Ribeiro Oliveira; Vasconcelos, Ana Tereza Ribeiro de; Gerber, Alexandra LehmkuhlMaritime ports are anthropogenic interventions capable of causing serious alterations in coastal ecosystems. In this study, we examined the benthic microbial diversity and community structure under the influence of two maritime ports, Mucuripe (MUC) and Pecém (PEC), at Equatorial Atlantic Ocean in Northeast Brazil. Those seaports differ in architecture, time of functioning, cargo handling and contamination. The...
Thermal stress and tropical reefs: mass coral bleaching in a stable temperature...
Soares, Marcelo de Oliveira; Teixeira, Carlos Eduardo Peres; Ferreira, Sarah Maria Cavalcante; Gurgel, Anne Larisse Alves RebouçasThis study reports on the deepest records (~ 24 m depth) of coral bleaching in a naturally temperature-stable environment (> 26 °C with an intra-annual variability of ~ 2 °C), which was recorded during a mass bleaching event in the locally dominant, massive scleractinian coral Siderastrea stellata in equatorial waters of Brazil (SW Atlantic). An inter-annual analysis (2002– 2017) indicated that this bleaching e...
A homage to the past aiming at the future
Rossi, Sergio; Cotovitz Junior, Luiz Carlos; Sousa, Paulo Henrique Gomes de Oliveira; Tavares, Tallita Cruz Lopes; Teixeira, Carlos Eduardo PeresAre the oceans dying? This is a question that many people are asking themselves more and more insistently. The answer is that in no case are they dying – but they are being transformed. Deeply. Unfortunately, this transformation has changed the ocean for a worst stage in terms of overall quality. Human-induced changes across the globe affect marine more than terrestrial ecosystems. And, at sea, there is a probl...
Bacteriome associated with Rhizophora mangle sediments within brazil semi-arid ...
Bezerra, Walderly Melgaço; Tavares, Tallita Cruz Lopes; Nogueira, Vanessa Lúcia Rodrigues; Normando, Leonardo Ribeiro Oliveira; Bomfim, Tatiana A.Microorganisms play important roles in nutrient cycling in mangrove ecosystems and knowledge on the plant/microorganism association is essential to better understand the functioning of this environment. Rhizophora mangle is the dominant tree species within Brazilian mangroves and little information is available on the microbiota associated with this plant species. In this context, the aim of this study was to s...
Getting by anthropocene with a little help from microbes
Tavares, Tallita Cruz LopesWhen modern man evolved in Africa 250,000 years ago by hunting and gathering, would he dream of megalopolis and flying machines? Would he ever understand how we managed to create and expand so much that this could cause our very decline like an Icarus that reached for the sun while the wax on his wings melts? Nowadays, as we find more and more evidence of the negative impacts we have caused to the biosphere, we...
Oil spill in South Atlantic (Brazil): Environmental and governmental disaster
Soares, Marcelo de Oliveira; Teixeira, Carlos Eduardo Peres; Bezerra, Luís Ernesto Arruda; Paiva, Sandra Vieira; Tavares, Tallita Cruz LopesIn early September 2019, dense crude oil began to wash the beaches of Brazil's tropical coast. Four months after the first report, the oil has already been found along >3000 km of the Brazilian coastline on >980 beaches and was recently observed along the Amazon coast, making this oil spill the most extensive and severe environmental disaster ever recorded in Brazilian history, in the South Atlantic basin, and ...
Sustainable development goals against COVID-19: the performance of brazilian ci...
Viana, Michael Barbosa; Matos, Fábio de Oliveira Tallita Cruz Lopes Tavares; Tavares, Tallita Cruz LopesSeveral researchers have detected the viral genome of SARS‐CoV‐2 in the stools of people (symptomatic or not) diagnosed with coronavirus disease‐2019 (COVID‐19). In domestic wastewater, this concentration can be between 19 and 5.5 x 106 viral genomes per liter of wastewater. Wastewater‐based epidemiology (WBE) starts from the premise that it is possible to estimate the number of people infected by the new coron...
Mesophotic ecosystems: distribution, impacts and conservation in the South Atla...
Soares, Marcelo de Oliveira; Tavares, Tallita Cruz Lopes; Carneiro, Pedro Bastos de MacêdoThis study reviews recent research on the South Atlantic Mesophotic ecosystems (MEs) and the pressures threatening them, and offers suggestions for their management and conservation.
