Breve currículo investigador:
My research experience spans a broad range of marine ecological and biological investigations with a strong focus on in situ sub-tidal surveys and experimental work which has spanned > 1200 research dives over the past 15 years. Much of my work has focused on investigating the effects of human impacts on marine ecosystems such as overfishing and ocean acidification. Yet, these impacts occurred in a multidimensional environment and are linked to other stressors. Hence, I am also interested in climate change, UV increase, pollution, eutrophication-hypoxia, habitat loss and spread of invasive species, and their web of interactions and feedbacks. The one thing in common of all my work is that it is supported by basic observations from nature combined with experimental manipulations. In my opinion, global change research should be based on a strong knowledge of the local natural history and the biology of the species in concert. In this sense, I focus on combining long data sets of the environment and biota to figure out the underlying ecological story.

Central to my interests is the biology and population dynamic of sea urchins, especially, key habitat modifying species that generate widespread collapse from macroalgae beds to undesired sea urchin-dominated barren grounds. On biological aspects of these invertebrates, I have explored a variety of topics across their life cycle, such as larvae development, settlement, reproduction, growth and mortality. At the community level, I have investigated the establishment and stability of alternative ecosystem states and the positive feedback mechanisms that provide resilience for each state. In this sense, I have an especial interest on study human-derived stressors that can act to erode resilience of desirable macroalgal beds while strengthening resilience of urchin barrens, thus exacerbating the risk, spatial extent and irreversibility of an unwanted regime shift for marine ecosystems. For this research topic, I have work at different Marine Protected Areas, as large-scale human exclusion ecosystem experiments, to test communities’ responses to human activities (mainly harvesting).

From larvae to marine ecosystems research, my ultimate goal is to promote high quality scientific knowledge to identify management actions promoting sustainability of important ecosystem services: fish resources, habitat regeneration, oxygen production, CO2 absorption, etc. Throughout my research and teaching I seek to growth a sustainable humanity conscience to reduce human impacts on the oceans and prolong our lives on Earth, because our future as species is the ocean.
