与蚂蚁引入相关的生态影响受到了相当多的关注，但大多数报告这些影响的研究都比较了入侵地点和未入侵地点之间的物种组合。鉴于这种时空比较的推理能力较低，需要采用替代方法来评估蚂蚁入侵导致本地物种丧失的说法。在这里，我们使用来自加利福尼亚海峡群岛两个不同的阿根廷蚂蚁根除计划的长期数据集来研究本地蚂蚁群落的丰富度和组成在入侵前后（但在开始治疗之前）如何变化。在两个不同岛屿的四个不同地点，入侵前的本地蚂蚁群落在物种丰富度、物种组成和多种指示物种的存在方面与未入侵（对照）地点的蚂蚁群落非常相似。入侵者到来的同时，物种丰富度大幅（> 75％）快速下降（一年内），物种组成发生变化，以及指示物种消失。这些影响有望通过阿根廷蚂蚁治疗后本地蚂蚁物种在先前入侵的地区重新定居而得到扭转，并且正在对这些地点的本地蚂蚁恢复进行长期研究。然而，阿根廷蚂蚁在该群岛其他岛屿上不受控制的蔓延，对包括许多特有类群在内的本土蚂蚁构成了严重威胁。
Ecological impacts associated with ant introductions have received considerable attention, but most studies that report on these impacts contrast species assemblages between invaded and uninvaded sites. Given the low inferential power of this type of space-for-time comparison, alternative approaches are needed to evaluate claims that ant invasions drive native species loss. Here, we use long-term data sets from two different Argentine ant eradication programs on the California Channel Islands to examine how the richness and composition of native ant assemblages change before and after invasion (but prior to the initiation of treatments). At four different sites on two different islands, pre-invasion native ant assemblages closely resembled those at uninvaded (control) sites in terms of species richness, species composition, and the presence of multiple indicator species. Invader arrival coincided with large (> 75%) and rapid (within 1 year) declines in species richness, shifts in species composition, and the loss of indicator species. These impacts will hopefully be reversed by the recolonization of formerly invaded areas by native ant species following Argentine ant treatment, and long-term studies of native ant recovery at these sites are ongoing. Unchecked spread of the Argentine ant on other islands in this archipelago, however, poses a grave threat to native ants, which include a number of endemic taxa.
