Zonation of benthic macrofauna on Cassino Beach, southernmost Brazil

Human Impact on the Benthic Macrofauna of Two Beach Environments with Different Morphodynamic Characteristics in Southern Brazil

Pollution, exploitation of resources, erosion and recreational activities produce the most common impacts that somehow alter the natural balance of beach ecosystems. The aim of this study was to compare the richness and abundance of the benthic macrofauna of two sectors, one non-urbanized and the other urbanized, on each of two morphodynamically different beaches. Sectors of each beach were ana...

Wave Attenuation on Muddy Bottoms – A Multidisciplinary Field Study Offshore Cassino Beach, Southern Brazil

A field experiment was performed offshore Cassino Beach, Southern Brazil. In this area mud deposits were observed, mainly originated from the Patos Lagoon. Episodically, and associated with storm waves able to transport the mud from offshore to the beach, the usual sandy beach is covered by mud. This is a unique process along the Brazilian coastline, and the field experiment aimed to record the...

Global diversity patterns in sandy beach macrofauna: a biogeographic analysis

Unlike the advances generated on land, the knowledge of global diversity patterns in marine ecosystems is limited to a small number of studies. For sandy beaches, which dominate the world's ocean shores, previous meta-analyses highlighted the role of beach morphodynamics in explaining species richness patterns. Oceanographic variables and historical processes have not been considered, even thou...
