In the context of globalization, research on invasive species has become increasingly important due to the growing number of species being relocated through human activities\u2014such as transport, trade, and others. Invasive species often cause significant problems as they compete with local flora and fauna, frequently disrupting the abundance and quality of native species. This results in a loss of biodiversity which, in the long term, can lead to substantial reductions in ecosystem services, such as lower fishery yields. Since the opening of the Suez Canal in 1869, the Eastern Mediterranean has undergone an unprecedented transformation in species composition, with the massive arrival of non-native species\u2014known as\u00a0Lessepsian migrants\u2014from the Red Sea. These species already account for more than a quarter of total catches in the Eastern Mediterranean, and sometimes even more. Some of them are now spreading as far as the Western Mediterranean.<\/p>\n<p>The\u00a0<a href=\"https:\/\/www.fondationbiodiversite.fr\/en\/the-frb-in-action\/programs-and-projects\/le-cesab\/gaspar\/\"><strong>FRB\u2013Cesab Gaspar<\/strong> <\/a>project\u00a0specifically investigated the mechanisms that enable a species to adapt to a new environment, in the context of\u00a0biological invasions\u00a0and\u00a0species adaptation to climate and global change. For the first time, the Gaspar project conducted a comprehensive study of all species inhabiting adjacent systems, in order to identify the processes that determine which ones become invasive. Such information is rarely available, and this approach had never been applied before.<\/p>\n<p>\u00a0<br \/>\nThis document summarizes, in just a few pages, the project\u2019s context and objectives, the methods and approaches used, the main findings, and the impacts on science, society, and both public and private decision-making.<\/p>\n","protected":false},"featured_media":0,"template":"","categories":[],"sujet_publi":[75,114,232],"angle":[],"type_ressource":[189],"class_list":["post-32740","ressource","type-ressource","status-publish","hentry","sujet_publi-biodiversite-et-climat-en","sujet_publi-biodiversite-et-oceans-en","sujet_publi-especes-exotiques-envahissantes-en","type_ressource-resultats-de-projet"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>GASPAR | A general approach to Species-Abundance relationships in a context of global change, reef fish species as a model - Fondation pour la recherche sur la biodiversit\u00e9<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.fondationbiodiversite.fr\/en\/ressource\/gaspar-adaptation-des-especes-de-poissons-envahissantes-dans-un-contexte-de-changement-global\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"GASPAR | A general approach to Species-Abundance relationships in a context of global change, reef fish species as a model - Fondation pour la recherche sur la biodiversit\u00e9\" \/>\n<meta property=\"og:description\" content=\"The invasion of non-native species is considered one of the main threats to biodiversity, leading to major changes in the structure and functioning of ecosystems.
