Qual'è il ruolo delle attività umane sulla proliferazione dell'alga Ostreopsis.
venerdì 3 giugno 2016

La Signora Daniela CATANIA, dottorante al laboratorio ECOMERS de l'Università Nice Sophia Antipolis, fà un punto della situazione sullo stato dei suoi lavori relativi agli impatti umani sulle vegetazioni costiere e la facilitazione dei fenomeni emergenti. (proliferazione dell'alga Ostreopsis)

Human impacts on coastal marine vegetation and the facilitation of Ostreopsis blooms in the NW Mediterranean Sea


The aim of the PhD project is to study the ecology of a toxic marine microalgae, Ostreopsis cf. ovata, causing blooms during the summer months which are an emerging phenomenon in shallow rocky coasts in temperate regions. Specifically, we approached the possible interactions between Ostreopsis blooms and the macroalgal assemblages along the marine coastline that may be strongly modified due to varying degrees of human impacts. We hopothesize that human impacts can indirectly facilitate Ostreopsis blooms by altering macroalgal assemblages composition and structure (i.e. complexity).  A literature review was compiled, in order to collect all the existing information of the preferential substrates, benthic communities and ecosystems where Ostreopsis blooms are commonly studied.

This PhD is funded by the PACA region, in partnership with the Accord RAMOGE, and has been partly performed in the framework of the European Project M3-HABs (Monitoring, Modelling and Mitigating Harmful Algal Blooms).

This poster was presented at the Conférence Nationale du “GDR Phycotox sur les microalgues toxiques” which took place in Villefranche-sur-mer on the 15th and 16th of March 2016.
