Marine forests, typically dominated by kelps of the orders Laminariales and Fucales, represent important blue-green infrastructures. They form one of the most productive and diverse ecosystem along rocky coasts worldwide and provide important ecosystem functions and -services (e.g. food, chemical substances, climate regulation, maintenance, tourism, science and education) underpinning economic activities along European coasts. Influenced by global change currently there is a shift in distribution of algal forests, possibly leading to a loss of unique genetic resources. Biogeographic boundaries in the NE Atlantic along with a low distribution potential of kelps probably limit connectivity and thereby reduce long-term fitness of these ecosystems. Project MARFOR aims to explain the future condition of marine forests by understanding the functional and genomic diversity and the resulting actual and possible future fitness of this key ecosystem. Major goals include: 1. Understand critical traits (adaptation, ecophysiology, genetic biodiversity and connectivity) of key species that facilitate function of algal forests along European coasts. 2. Model and predict consequences of global change through application of knowledge on genomic biodiversity, dynamics, and critical traits of these marine communities. This shall help to ensure long-term sustainability of ecosystem function and ecosystem services of marine forests. Collaborating project teams have outstanding complementary expertise and geographically reside along relevant coastal areas. This leads to a qualified partnership and an added value to best study ecological, eco-physiological and genomic differences of species and populations along European coasts. To achieve this we will replicate interdisciplinary comparisons at different sites. This will be supported by a large citizen science initiative allowing communication with and participation of the public and local stakeholders. Results on distribution, ecophysiology and species-specific temperature traits will allow predictions for current and future climate scenarios. Based on sampling along European coasts we will estimate genetic connectivity and functional genetic diversity of key species and meta-populations which will be interpreted in the context of distribution models. This shall help to implement conservation practices, evaluate survival capacity of populations, lay the foundation to manage nature conservancy areas and support the blue economy sector. White papers will assist stakeholders in the implementation of sound climate policies and strategies based on a cost-benefit analysis for sustainable development.

海洋森林是重要的蓝绿色基础设施，主要以海带目和褐藻目为主。它们形成了世界上沿岩石海岸最具生产力和多样性的生态系统之一，并提供重要的生态系统功能和服务（如食品、化学物质、气候调节、维护、旅游、科学和教育），支撑着欧洲沿海地区的经济活动。受全球变化的影响，目前藻林的分布发生了变化，可能导致独特遗传资源的丧失。东北大西洋的生物地理边界以及海带的低分布潜力可能限制了这些生态系统的连通性，从而降低了这些生态系统的长期适应性。MARFOR项目旨在通过了解这一关键生态系统的功能和基因组多样性以及由此产生的实际和可能的未来适应度来解释海洋森林的未来状况。主要目标包括：了解促进欧洲海岸藻类森林功能的关键物种的关键特征（适应性、生态生理学、遗传生物多样性和连通性）。2. 通过应用基因组生物多样性、动态和这些海洋群落的关键特征方面的知识，建立模型并预测全球变化的后果。这将有助于确保海洋森林的生态系统功能和生态系统服务的长期可持续性。合作项目团队具有出色的互补专业知识，并且在地理上居住在相关的沿海地区。这导致了一种合格的伙伴关系，并为最好地研究欧洲沿岸物种和种群的生态、生态生理和基因组差异提供了附加价值。为了达到这个目的，我们将在不同的地点重复跨学科的比较。这将得到一个大型公民科学计划的支持，该计划允许与公众和地方利益相关者进行沟通和参与。分布、生态生理和物种特有温度特征的结果将有助于预测当前和未来的气候情景。在欧洲沿海取样的基础上，我们将估计关键物种和元种群的遗传连通性和功能遗传多样性，这将在分布模型的背景下进行解释。这将有助于实施保护措施，评估人口的生存能力，为自然保护区的管理奠定基础，并支持蓝色经济部门。白皮书将根据可持续发展的成本效益分析，帮助利益攸关方实施合理的气候政策和战略。
