Introduction
I am a research scientist specialized in marine natural resources and biological oceanography, focusing my attention in the health indicators of coastal benthic suspension feeder populations, flows of matter and energy in the benthic-pelagic coupling, the animal forests as carbon sinks, and the management and conservation of benthic marine wildlife. I have been working in the animal forests of warm temperate, polar, tropical and cold temperate seas.

Direct human pressure on Marine Protected Areas (MPAs) adds to climate change impacts on marine habitats, especially in coastal biodiversity hot spots. Understanding MPA user perception towards the Coastal marine Habitats (CMHs) could improve awareness of the challenges that such areas have to face, eventually providing insights for the design of c...
Article
The ocean transformation due to the direct or indirect human influence is a fact. One of the most affected ecosystems are the benthic ones, where bottom trawling, urban/ agricultural development and climate change (among other things) deeply transform the bottom communities. Among these threatened communities, the marine forest is the most complex....
