尽管走廊经常被认为是减轻栖息地碎片化的负面影响的一种方式，但人们仍然担心走廊可能会促进入侵物种的传播，从而损害当地物种。入侵火蚁，邀请火蚁，有两种社会形式。相对于一夫多妻型，一夫多妻型的扩散能力有限。我们之前在大型廊道实验中的工作表明，在以多角形为主的景观中，由廊道连接的生境斑块的火蚁密度高于未连通斑块的火蚁密度，而本地蚂蚁物种丰富度低于未连通斑块。我们预计这些观察到的廊道效应是暂时的，即随着火蚁最终在斑块内完全建立，连通斑块与未连通斑块之间的火蚁密度和本地蚂蚁物种丰富度差异将随着时间的推移而减小。在最初研究的6到11 年后，我们通过重新采样以一夫多妻火蚁为主的三个景观来检验这一预测。在这些景观中，连通和不连通的生境斑块之间的火蚁密度差异正如预期的那样减小。本地蚂蚁物种丰富度的差异是可变的，但在最后2 年采样的差异最小。这些发现支持我们对这种入侵蚂蚁的瞬时走廊效应的预测，并强调了时间动态在评估栖息地连通性对种群和群落影响的重要性。
Although corridors are frequently regarded as a way to mitigate the negative effects of habitat fragmentation, concerns persist that corridors may facilitate the spread of invasive species to the detriment of native species.The invasive fire ant,Solenopsis invicta,has two social forms. The polygyne form has limited dispersal abilities relative to the monogyne form. Our previous work in a large‐scale corridor experiment showed that in landscapes dominated by the polygyne form, fire ant density was higher and native ant species richness was lower in habitat patches connected by corridors than in unconnected patches.We expected that these observed corridor effects would be transient, that is, that fire ant density and native ant species richness differences between connected and unconnected patches would diminish over time as fire ants eventually fully established within patches. We tested this prediction by resampling the three landscapes dominated by polygyne fire ants 6 to 11 years after our original study.Differences in fire ant density between connected and unconnected habitat patches in these landscapes decreased, as expected. Differences in native ant species richness were variable but lowest in the last 2 years of sampling.These findings support our prediction of transient corridor effects on this invasive ant and stress the importance of temporal dynamics in assessing population and community impacts of habitat connectivity.
