非洲窄域和广域蜻蜓和豆娘成分变化的驱动因素

我们的目的是通过区分窄范围物种和广布物种组成更替背后的环境和地理驱动因素，探索是什么过程主导了蜻蜓（蜻蜓目：鞘翅目）和豆娘（蜻蜓目：颧翅目）的群落组合。我们分别探讨了蜻蜓和豆娘的物种更替，使用zeta多样性来测量多个集合体之间的成分更替。具体来说，蜻蜓和广布蜻蜓在年平均气温、气温季节性和年降水量发生微小变化时都表现出快速的更替，而豆娘的主要更替驱动因素是地点之间的距离，其次是气候变量。因此，我们的研究结果表明，虽然豆娘的有限扩散能力也会影响群落的组合，但鸟类的更替主要是由气候驱动的。气候变化可能会导致鸟类的组成发生重大变化，这给非洲的保护规划带来了挑战，因为如果它们的活动范围转移到保护区之外，以前受到保护的物种组合可能不再受到保护。对于豆娘来说，适应是一个主要问题，由于其扩散能力有限且对气候敏感，它们可能无法有效迁徙以应对不断变化的气候条件。在每个亚目中，分布范围较窄的物种和分布广泛的物种的基本集结过程并无显著差异，这表明在非洲，针对每个亚目的保护规划可能就足够了。
