Rocky coasts represent three quarters of all coastlines worldwide. These areas are part ecosystems great ecological value, but their steep configuration and elevation make field surveys difficult. This fact, together with lower variation rates, explains the numbers publications about cliffs rocky in general compared those beach-dune systems. The introduction UAVs research, has enormously expand...

Improving knowledge of the processes driving coastal flooding is a key issue in era climate change, especially for decision support public policies and operational forecasting. From regional to city scales, different interact, such as tide, storm surge, waves, wave setup, or infra-gravity further depend on area topography, bathymetry, sedimentology external forcings. While sandy beaches have be...

The ecological consequences of human-driven overexploitation and loss of keystone consumers are still unclear. In intertidal rocky shores over the world, the decrease of keystone macrograzers has resulted in an increase in the dominance of herbivores with smaller body (i.e., "mesograzers"), which could potentially alter community assembly and structure. Here, we experimentally tested whether me...
