世界自然保护联盟的红色名录是对物种受威胁状况进行分类的最著名的系统，但目前缺乏对遗传多样性的明确考虑，因此可能无法说明物种对未来环境变化的潜在适应。为了弥补这一差距，我们将全范围的遗传分析与IUCN红色名录评估相结合，计算了模拟范围损失下凤凰木属物种遗传多样性的损失。模拟范围损失涉及随机损失的人口，旨在模拟正在进行的栖息地破坏。我们发现遗传多样性的丧失和范围之间有很强的关系。此外，我们发现之间的对应关系的遗传多样性和阈值的“非威胁”与“受威胁”的IUCN红色名录categories.Our结果支持的观点，即目前的威胁阈值的IUCN红色名录标准反映了遗传多样性，因此进化潜力，虽然受威胁的类别之间的遗传多样性的区别是不太明显。因此，通过用遗传数据补充传统的保护评估，可以对自然保护联盟红色名录评估的生物稳健性有新的认识。
The best known system for classifying threat status of species, the IUCN Red List, currently lacks explicit considerations of genetic diversity, and consequently may not account for potential adaptation of species to future environmental change. To address this gap, we integrate range-wide genetic analysis with IUCN Red List assessments.We calculated the loss of genetic diversity under simulated range loss for species ofDelonix(Leguminosae). Simulated range loss involved random loss of populations and was intended to model ongoing habitat destruction. We found a strong relationship between loss of genetic diversity and range. Moreover, we found correspondence between levels of genetic diversity and thresholds for ‘non-threatened’ versus ‘threatened’ IUCN Red List categories.Our results support the view that current threat thresholds of the IUCN Red List criteria reflect genetic diversity, and hence evolutionary potential; although the genetic diversity distinction between threatened categories was less evident. Thus, by supplementing conventional conservation assessments with genetic data, new insights into the biological robustness of IUCN Red List assessments for targeted conservation initiatives can be achieved.
