| The Canary and Cape-Verde archipelagos are two groups of volcanic islands often cited as case examples of the surface expression of two distinct hot-spot plumes. However, several considerations that we enumerate suggest a link between the two archipelagos. Using seismic profiles we describe a continuous morphological basement ridge that exists between the two archipelagos. We then examine the stratigraphic record available from field data on Fuerteventura Island (Canary) and Maio Island (Cape-Verde) and from a few Deep Sea Drilling Project (DSDP) holes. The geological history of these volcanic islands is very similar since the formation of their oceanic basement during the Late Jurassic. They share the same and synchronious sedimentary evolution... |

| ABSTRACT Wildland fires can be responsible for negative impacts on the environment, causing damage to the fauna and flora and increasing the release of greenhouse gases. In the state of Amazonas, wildland fires represent a risk for biodiversity conservation, since more than 95% of the state is covered by Amazon rainforest, one of the largest and most biodiverse tropical forests of the world. This study aimed to analyze the spatiotemporal variation of fire occurrence from 2003 to 2016 in the state of Amazonas, based on data from the AQUA satellite processed by the Brazilian National Institute for Space Research, using the “Collection 5” detection algorithm. The correlation between fire incidence versus anthropogenic and climatic variables was also tested. A... |
