Insects play a central role in the functioning of terrestrial and freshwater ecosystems and contribute to a multitude of ecosystem services in managed and unmanaged systems Even local declines of insect abundance and richness can have enormous ecological and economic consequences. Evidence-informed conservation actions are essential to prevent potential cascading consequences of insect declines, and to help declining populations recover. Policy-makers rely on syntheses of primary research, such as reviews and meta-analyses, when making decisions about which conservation actions to implement. These evidence reviews vary in their quality, and do not necessarily synthesise the full range of scientific evidence found in the primary literature, which hampers decision-making. This evidence review map will identify, catalogue, and describe evidence reviews that investigate actions and policies to conserve insect biodiversity. This will help policy makers identify relevant reviews and researchers to identify synthesis gaps. It will also generate a list of conservation actions which can feed into future synthesis projects. We will produce an interactive database of evidence reviews, acting as a bibliography for policy-makers, curate a list of insect conservation actions that have been reviewed, and identify synthesis gaps for conservation actions that have not been reviewed. We will search for evidence reviews across seven large, generic bibliographic databases, a database of environmental reviews, and five grey literature resources using a search string consisting of an insect substring, a biodiversity or population response substring, an evidence synthesis substring, and a conservation substring. The results will be deduplicated and then screened at title and abstract (concurrently) and full text levels against predefined inclusion criteria. We will initially perform consistency checking on a subset of records at each level to ensure the inclusion criteria are sufficiently clear and understood by multiple reviewers. We will extract a suite of descriptive meta-data from relevant reviews, including a description of the action and information on each review’s focal taxa, biomes, and locations. If resources allow, we will apply the CEESAT critical appraisal tool for evidence reviews to assess validity of individual records and the evidence base as a whole. We will summarise our findings in an interactive database of reviews and other visualisations, including evidence atlases and heat maps (cross tabulations of the volume of evidence across two categorical variables). The findings of the evidence review map will support the identification of synthesis gaps and clusters that may warrant further attention through secondary research.

关于保护昆虫的保护行动，有哪些证据？系统的文献综述图的方案

昆虫在陆地和淡水生态系统的功能中发挥着核心作用，并在有管理和无管理的系统中为多种生态系统服务做出了贡献。即使本地昆虫数量和丰富度的下降也会带来巨大的生态和经济后果。采取有据可依的保护行动对于防止昆虫数量下降的潜在级联后果并帮助数量下降的种群恢复至关重要。政策制定者在决定实施哪些保护措施时，依赖于基础研究的综合，例如评论和荟萃分析。这些证据综述的质量各不相同，并不一定综合了主要文献中发现的所有科学证据，从而妨碍了决策。该证据审查图将识别，分类，并描述证据审查，以调查保护昆虫生物多样性的行动和政策。这将有助于政策制定者确定相关评论，并帮助研究人员确定综合差距。它还将生成一份保护措施清单，这些清单可用于未来的综合项目。我们将建立一个交互式的证据审查数据库，作为决策者的参考书目，整理一份已审查过的昆虫保护行动清单，并找出未审查过的保护行动的综合差距。我们将使用由昆虫子字符串，生物多样性或种群响应子字符串，证据综合子字符串，搜索子字符串组成的搜索字符串，在7个大型通用书目数据库，环境评论数据库和5种灰色文献资源中搜索证据评论，和一个保护子串。将对结果进行重复数据删除，然后根据预定义的包含标准在标题和摘要（同时）以及全文级别进行筛选。我们将首先在每个级别上对记录的子集执行一致性检查，以确保包含标准足够清晰并被多个审阅者理解。我们将从相关评论中提取一套描述性元数据，包括对操作的描述以及有关每个评论的重点类群，生物群系和位置的信息。如果资源允许，我们将使用CEESAT关键评估工具进行证据审查，以评估单个记录和整个证据基础的有效性。我们将在评论和其他可视化的交互式数据库中总结我们的发现，包括证据地图集和热图（跨两个分类变量的证据量交叉表）。证据综述图的发现将支持鉴定合成缺口和聚类，这可能需要通过二次研究进一步关注。
