Puerto de la Cruz, Tenerife, Spain (1954 -). Doctor in Biological Sciences from the University of La Laguna (1982) and Assistant Professor (1982-1984), University Holder (1984-2009) and University Professor (2009-2017), currently retired. Professor of Marine Botany and other related subjects. Scientific activity developed since 1979 researching the plant biodiversity of the marine benthos. Working on about 20 research projects, resulting in about 60 scientific papers presented at conferences, and more than 170 publications, of which 20 are books, 11 book chapters and the rest are articles (60 indexed in JCR). His research supports a solid current knowledge on the biodiversity of the Canarian phytobenthos, and his scientific achievements include the discovery and description of 12 new species of macroalgae, and his contributions on the vegetative and reproductive morphology of the coralline algae, seasonal ephemeral gelatinous red algae of unstable substrates and Mediterranean and Macaronesian Botryocladia species. His most recent research combines morphological, phenological and molecular evidence in the study of cryptic species, the analysis of isolated habitats (shallow sciaphilic environments) and the analysis of recent changes in Canarian phytobenthos due to the introduction of species (invasive species) and regression of engineering communities linked to environmental changes (global warming).
