Citizensare therefore increasingly involved in monitoring programs, appointed as citizen scientists withpotential to delivering key data at near to no cost to address environmental challenges, thereinfostering scientific knowledge and advising policy- and decision-makers. One of the first andmost successful examples of marine citizen science in the Mediterranean is represented by theintegrative and collaborative implementation of several jellyfish-spotting campaigns in Italy, Spain,Malta, and Tunisia starting in 2009. Altogether, in terms of time coverage, geographic extent, andnumber of citizen records, these represent the most effective marine citizen science campaigns thus farimplemented in the Mediterranean Sea. Here, we analyzed a collective database merging records overthe above four countries, featuring more than 100,000 records containing almost 25,000 observationsof jellyfish specimens collected over a period of 3 to 7 years (from 2009 to 2015) by citizen scientistsparticipating in any of the national citizen science programs included in this analysis. Such a widecitizen science exercise demonstrates a valuable and cost-effective tool to understanding ecologicaldrivers of jellyfish proliferation over the Western and Central Mediterranean basins, as well as apowerful contribution to developing tailored adaptation and management strategies; mitigatingjellyfish impacts on human activities in coastal zones; and supporting implementation of marinespatial planning, Blue Growth, and conservation strategies.
