Potentially toxic epiphytic dinoflagellate assemblages on macroalgae in the NW Mediterranean
The dinoflagellate assemblage follows a clear seasonal pattern, achieving maximum cell concentration during spring and summer without significant relative changes in the species composition.

A real-time PCR-based assay for rapid detection of all toxic species of the Alexandrium genus in both fixative-preserved environmental samples and cultures is developed, confirming that real- time PCR could be a valid, fast alternative procedure for the detection and quantification of target phytoplankton species during coastal water monitoring.
Overview of eutrophication indicators to assess environmental status within the European Marine Strategy Framework Directive
Harmful microalgae blooms (HAB); problematic and conditions that induce them.
High Resolution Spatio-temporal Detection of Potentially Harmful Dinoflagellates in Confined Waters of the NW Mediterranean
A systematic sampling programme was carried out in a large number of confined waters (principally harbours) along the Catalan coast (NW Mediterranean) in the context of a new Monitoring Programme to provide an early warning of potentially widespread HABs.
Drifting plastic debris as a potential vector for dispersing Harmful Algal Bloom (HAB) species
Macroscopic observations of floating plastic debris collected at several places along the Catalan coast showed conspicuous green-yellow patches adhered to them, which are suggested to be drifting plastic debris as a potential vector for microalgae dispersal.
Resting cysts of the toxigenic dinoflagellate genus Alexandrium in recent sediments from the Western Mediterranean coast, including the first description of cysts of A. kutnerae and A. peruvianum

The cyst concentration data revealed A. catenella and A. minutum to be the most abundant cysts in the region, and they were detected in semi-enclosed waters, such as harbours, highlighting the importance of water exchange in the accumulation of cyst beds of these species.
CHARACTERIZATION OF NW MEDITERRANEAN KARLODINIUM SPP. (DINOPHYCEAE) STRAINS USING MORPHOLOGICAL, MOLECULAR, CHEMICAL, AND PHYSIOLOGICAL METHODOLOGIES 1
Recurrent fish kills in the Spanish Alfacs Bay have been detected during winter seasons since 1994, and were attributed to an unarmored, ichthyotoxic, dinoflagellate, initially identified as Gyrodinium corsicum Paulmier, Berland, Billard, & Nezan, but they were separated into two genetically distinct groups.
Pseudo-nitzschia species on the Catalan coast: characterization and contribution to the current knowledge of the distribution of this genus in the Mediterranean Sea
Morphological studies coupled with molecular biological characterization, mating tests and biogeographic distribution analyses provide a critical theoretical basis for testing and/or implementing the current phylogenetic framework in the genus Pseudo-nitzschia.
Is the distribution of the toxic dinoflagellate Alexandrium catenella expanding along the NW Mediterranean coast
The toxic dinoflagellate Alexandrium catenella is usually known as a cold waters species; however, during the summer of 1996 a bloom was observed in the Barcelona harbour (water temperatures above…
