Monitoring of carcinofauna abundance and diversity during eight years of expressway construction in Santa Catarina, Brazil

Crustaceans are important in estuarine ecosystems, transferring energy to higher trophic levels and contributing to artisanal and industrial fisheries. This paper aims to evaluate the carcinofauna diversity and abundance in Saco dos Limões and how this changed when affected by dredging during the co...
