Welcome to the METABARPARK Project website. The project aims to apply the new high throughput sequencing technologies to characterize benthic communities in the Spanish Marine National Parks using environmental DNA (metabarcoding). Our main objective is to characterize the hidden biodiversity which is usually overlooked by traditional methods. We will also try to assess the community impacts of invasive seaweeds.

Second collecting trip in Cabrera done!

In October, 2 to 8, we made the second sampling foreseen in the workplan in the Cabrera Archipelago National Park. As in the previous year, we organized a joint trip with members of the CORCLIM project. In this way we optimized costs and logistics, and of course it was an excellent opportunity for interaction and exchange of experiences.

In this trip we worked again in the Imperial Islet, where we sampled the same communities as in the previous year. In addition, we got samples from a community dominated by the invasive seaweed Caulerpa cylindracea at 30 m depth. Weather was far from perfect, and we had to cope with some unexpected problems such as the breakdown of the compressor, but we finally managed to get back with all samples foreseen.

By now, all samples collected in Islas Cíes in May and in Cabrera in October have been processed, sieved into size classes, their DNA extracted, and we are working in the amplification of the two genes chosen, 18S and COI. In one-two weeks we expect to send the samples to Fasteris (Switzerland) for parallel sequencing.
