1.遗传多样性对物种的持续存在很重要，已对林木实施了基因保护单位，以保护遗传多样性和原地进化过程。《生物多样性公约》将保护遗传多样性规定为爱知目标，因此，我们探讨了更广泛地实施GCU的可能性。我们的全球系统评价表明，GCU目前主要用于具有经济重要性的植物物种（研究的158种植物中有109种），但向土地管理者和自然保护主义者发送的问卷调查（60英国）参与者）表示强烈支持将遗传信息充分纳入保护管理（90%同意），并为其他植物和动物类群创建GCU。通过对英国的四个案例研究，对于在遗传威胁和种群动态方面各不相同的重要保护物种（两种昆虫物种、一种真菌和一种植物），我们强调GCU实施标准需要灵活，以考虑目标物种有效繁殖种群规模和地理范围的变化。更广泛地采用全球协调单位将确保受威胁的遗传多样性得到保护，并支持有助于适应不断变化的环境的进化进程。
1. Genetic diversity is important for species persistence and Gene Conservation Units (GCUs) have been implemented for forest trees to protect genetic diversity and evolutionary processes in situ. The Convention on Biological Diversity stipulates the protection of genetic diversity as an Aichi target, and so we explore the potential for GCUs to be implemented more widely.2. Our global systematic review showed that GCUs are currently implemented primarily for plant species of economic importance (109/158 species studied), but a questionnaire sent to land managers and conservationists (60 U.K. participants) revealed strong support for fully integrating genetic information into conservation management (90% agree), and for creating GCUs for other plant and animal taxa.3. Using four case studies of U.K. species of conservation importance which vary in genetic threat and population dynamics (two insect species, a fungus and a plant), we highlight that GCU implementation criteria need to be flexible to account for variation in effective breeding population size and geographic extent of target species. The wider uptake of GCUs would ensure that threatened genetic diversity is protected and support evolutionary processes that aid adaptation to changing environments.
