International Legal Approaches to Waste Water Discharges. Opening speech
2002
En este discurso inaugural, realizo una introducción a la frustrante situación jurídica en la que se encuentran las descargas de aguas residuales a nivel internacional. Las descargas de aguas residuales son la mayor fuente de contaminación marina y, en consecuencia, ellas representan el mayor riesgo actual para la protección del medio ambiente marino. In this opening speech, I make an introduction to the disappointing legal situation of waste water discharges at international level. Waste water discharges is the main source of marine pollution and, therefore, they represent the major current risk to the protection of the marine environment.

The early plastisphere of biodegradable and non-biodegradable plastic films in marine environment
2019
Introduction Plastic items are the most common form of marine debris and plastic accumulation in marine ecosystems is a serious environmental issue. One possible solution to reduce the amount of synthetic polymers released in the environment is to substitute them with bio-based polymers. When released in marine environments, plastics are readily colonized by biofilm-forming microorganisms, the so called “plastisphere community”, which may include pathogenic, invasive and plastic-degrading species; the composition and influence of the plastisphere on the fate of plastic is largely unknown. The aim of this study is to investigate the early biofilm formation and the structure and diversity of …
PICOPHYTOPLANKTON DYNAMICS IN NOISY MARINE ENVIRONMENT
2012
We present a stochastic reaction-diffusion-taxis model to describe the picophytoplankton dynamics along a water column. The model, which is valid for poorly mixed waters, typical of the Mediterranean Sea, considers intraspecific competition of picophytoplankton for light and nutrients. Random fluctuations of environmental variables are taken into account by adding a source of multiplicative noise to the diffusion equation for the picophytoplankton biomass concentration, whose distribution along the water column shows a maximum at a certain depth. After converting our results into chlorophyll a concentrations, we compare theoretical distributions, obtained for different noise intensities, wi…
