Anchialine caves are characterized by high levels of endemism and extreme conditions. However, few ecological studies have been conducted in these ecosystems. This study integrates biotic and abiotic parameters of two sets of cave systems with contrasting high and low species richness. Seven ecological patterns are used to explain the expected species richness and density in an anchialine cave. In addition, the population size for conspicuous macrofauna was estimated. The high impact that single-events have on anchialine fauna are also reported. These findings reinforce the conclusions of previous studies of the high extinction risk of anchialine cave fauna, and substantiate the necessity of ad hoc conservation strategies for anchialine caves.
地下河洞穴的特点是特有种丰富度高和极端环境。然而，对这些生态系统的生态研究很少。本研究整合了两套具有高和低物种丰富度对比的洞穴系统的生物和非生物参数。使用七个生态模式来解释在地下河洞穴中预期的物种丰富度和密度。此外，还估算了明显的大型动物的种群规模。还报告了单一事件对地下河动物群的巨大影响。这些发现加强了先前对地下河洞穴动物群灭绝风险高的研究结论，并证实了为地下河洞穴制定专门保护策略的必要性。
