Abstract The trace metal geochemistry of atmospheric dust and terrestrial surface particles were studied on the Qatar Peninsula from February 2014 to November 2015. We included samples of the mega dust-storm event on 01–02 ...
Artisanal fishing of spiny lobsters with gillnets — A significant anthropic impact on tropical reef ecosystem
(2015 , Article)
Abstract Artisanal fishing activity with gillnets to capture the spiny lobster is a common practice along the coastal reefs of Brazil. This research aims to understand the impact that this artisanal fishing practice is ...
Extending the southern range of four shrimps (Crustacea: Decapoda: Stenopodidae, Hippolytidae and Alpheidae) in southwestern Atlantic (27oS) and confirming the presence of Mediterranean Stenopus spinosus Risso, 1827 in Brazil
