• 1. Like many sea‐duck populations, the British breeding population of common scoters Melanitta nigra has declined markedly. In 2009, a study was established to measure factors affecting lake use by breeding scoters, to inform conservation measures. That study, published in Aquatic Conservation: Marine and Freshwater Ecosystems (AQC) in 2016, showed that lakes used by scoters had relatively more shallow water and large invertebrates. Furthermore, lakes with abundant large invertebrates had relatively few brown trout Salmo trutta. These results probably reflect the importance of foraging habitat (shallow water), prey abundance (large invertebrates), and competition for prey (trout abundance) in influencing scoter lake use.
• 2. To develop this study, additional research, and scoter conservation measures, we formed a long‐term partnership, comprising nature conservation non‐governmental organizations, statutory agencies, fisheries managers and the regional hydropower company. The partnership meets regularly to coordinate and review research and develop conservation measures, building on the earlier lake‐use study.
• 3. At key scoter lakes managed for hydropower, the partnership negotiated a revised water level management regime, favouring shallow water availability in the breeding season. This regime was informed by additional research, showing the value of certain islands for nesting scoters, and water level requirements to maintain these as islands.
• 4. In a different key scoter area — an extensive near‐natural peatland where recreational angling takes place — the partnership established a trial of increased brown trout angling, with increased fish removal, to determine whether this would increase invertebrate prey abundance and benefit breeding scoters. Both conservation interventions are currently being evaluated by detailed monitoring.
• 5. Overall, the earlier study published in AQC, was important in strengthening and informing our researcher–practitioner partnership, as we collaborated within an adaptive management framework to reverse scoter declines. Long‐term interdisciplinary partnerships are likely to have an important role to play in general, for the successful conservation of aquatic biodiversity.

从研究到保护伙伴关系：开发方法来恢复常见的种群

• 1.与许多海鸭种群一样，英国普通苏格兰黑背黑背猴的繁殖种群明显减少。2009年，建立了一项研究，以通过繁殖苏格兰人来衡量影响湖泊使用的因素，以提供保护措施。该研究于2016年发表在《水生保护：海洋和淡水生态系统》（AQC）上，该研究表明，苏格兰人使用的湖泊具有相对较浅的水域和较大的无脊椎动物。此外，具有丰富的大型无脊椎动物的湖泊有相对较少的褐鳟褐鳟。这些结果可能反映了觅食生境（浅水），猎物丰富度（大型无脊椎动物）以及竞争猎物（鳟鱼丰富度）在影响滑行湖使用中的重要性。
• 2.为了开展这项研究，开展其他研究并采取节约措施，我们建立了长期合作伙伴关系，由自然保护非政府组织，法定机构，渔业经理和区域水电公司组成。该伙伴关系定期开会，以在较早的湖泊使用研究的基础上协调和审查研究并制定保护措施。
• 3.在管理水力发电的主要死湖上，伙伴关系商定了修订后的水位管理制度，以利于繁殖季节的浅水供应。该制度是通过其他研究获得信息的，该研究显示了某些岛屿对嵌套苏格兰人的价值，以及维持这些岛屿为岛屿所需要的水位。
• 4.在另一个关键的得分区-发生娱乐垂钓的广阔的近自然泥炭地-伙伴关系建立了增加鳟鱼垂钓和去除鱼的试验，以确定这是否会增加无脊椎动物猎物的数量并有利于繁殖。 。目前正在通过详细监测评估这两种保护措施。
• 5.总体而言，在AQC上发表的较早研究对于加强和告知我们的研究者与从业者伙伴关系非常重要，因为我们在适应性管理框架内进行了合作以逆转得分下降的趋势。长期的跨学科伙伴关系可能对成功保护水生生物多样性总体上起重要作用。
