Promoting action on broad ocean challenges by delving into the past, present and future of European syngnathids

海龙科（海马，海龙，海龙和海龙）是硬骨鱼科的一部分，很容易通过其独特的繁殖模式，雄性怀孕来识别。在欧洲沃茨内，大约有18种海龙，55%被列为数据不足，83%目前的种群状况未知。这些数字完美地显示了我们对沿海生态系统健康的知识差距，这严重限制了我们发现、扭转或避免假设扰动的能力。在EUROSYNG，我们将协助欧洲国家遵循世界自然保护联盟决议WCC-2020-Res-095的要求，通过提供以下信息，我们将在编辑一张清晰的欧洲海龙种群状况的图片时，详细描述欧洲海龙种群状况。要做到这一点，我们将提供一个按时间顺序的观点，海龙分布（跨越过去，现在和未来），衡量目前的人口健康和连接，使用传统的（例如，博物馆数据、人口普查）和现有技术的方法（例如，基因组学）。人口基因组学依赖于基因组重新测序的约5000人，映射到现有的和新生成的高质量的染色体水平的基因组，将提供重要的见解健康状况，连接和迁移潜力的欧洲海龙种群。这些数据将有助于对现有海洋保护区进行批判性研究，同时有助于建立新的保护区，以帮助减轻气候变化的影响。使用海龙作为旗舰物种，我们将从公众与这些标志性生物的情感联系中获益，以提高对当地和全球保护问题的认识，即气候变化的可预见影响，并提高海洋素养和对公民科学的兴趣。此外，我们将开发新的工具来支持蓝色经济，包括自然旅游，并帮助调解海龙，自然爱好者和渔民之间不可避免的互动。我们的数据将有助于透明的决策过程，从而制定考虑到人类和海龙种群利益的渐进立法。EUROSYNG汇集了来自7个欧洲国家（将对10个国家进行抽样调查）的具有互补专业知识的海龙科专家，以及大量的合作伙伴利益相关者。本建议旨在提供不仅对被调查国家有用的工具（例如，国家红名单），也为世界自然保护联盟（全球红名单）和欧盟，因为我们将产生第一个详细的图像海龙种群的健康。结合过去、现在和未来的分布数据，我们将帮助欧盟更好地确定其30 × 30目标，展示在当前气候变化情景下应该保护的地区，同时测试新的保护工具。

Syngnathids (seahorses, pipefish, pipehorses and seadragons) are part of a diverse family of teleost fish, easily recognizable by their unique mode of reproduction, male pregnancy. Within European waters, there are approximately 18 syngnathid species, 55 % listed as Data Deficient and 83 % with unknown current population status. These numbers perfectly showcase the knowledge gap on the health of our coastal ecosystems which severely restricts our ability to detect, reverse or avoid hypothetical perturbations. In EUROSYNG, we will assist European states in following the requirements of the IUCN resolution WCC-2020-Res-095 by provipäischen Staaten dabei unterstützen, die Anforderungen der IUCN-Resolution WCC-2020-Res-095 zu erfüllen, indem wir ein klares Bild des Status der Syngnathidenpopulationen in Eding a clear portrait of syngnathid population status within Europe. To do so, we will offer a chronological view of syngnathid distribution (spanning the past, present and future), measure present day population health and connectivity, using both traditional (e.g., museum data, population censuses) and state of the art methodologies (e.g., genomics). Population genomics relying on genome re-sequencing of approximately 5000 individuals, mapped on existing and newly generated high-quality chromosome level genomes, will provide crucial insights into the health status, connectivity and migration potential of European syngnathid populations. These data will allow for a critical look into existing MPAs while assisting in the creation of new protected areas that can help mitigate the effects of climate change. Using syngnathids as flagship species, we will profit from the public’s emotional connection to these iconic creatures to raise awareness to local and global conservation issues, namely the foreseeable impacts of climate change, and boost both ocean literacy and interest in consequential citizen science. Furthermore, we will develop new tools to support blue economy, including nature tourism, and help mediate the inescapable interactions between syngnathids, nature enthusiasts and fishermen. Our data will assist in transparent decision-making processes leading to the creation of progressive legislation that takes the interest of human and syngnathid populations into consideration. EUROSYNG gathers syngnathid specialists, with complementary expertise, from 7 European countries (that will sample 10 countries), together with a vast array of partner stakeholders. This proposal aims at providing tools that will be useful not only for the surveyed countries (e.g., national red listing), but also for IUCN (global red listing) and the EU as we will produce the first detailed image of syngnathid populations health. Combining distribution data from the past, present and future, we will assist the EU in better targeting its 30 by 30 goals, showcasing areas that should be protected given the current climate change scenarios, while testing new conservation tools.
