生境破碎化通过生境丧失、连通性降低和边缘效应影响全球生态系统。然而,这些景观因素往往是混淆,留下了很多关于它们的相对影响,特别是物种相互作用的调查。在一个景观实验中,我们研究了蚂蚁种子传播的连接性和边缘效应的后果。我们发现,蚂蚁传播种子更远的栖息地斑块连接的走廊,但只有在补丁中心。我们没有看到对移动的种子总数或蚂蚁检测种子的速度的影响。此外,我们没有看到任何差异,蚂蚁群落组成的补丁类型,这表明蚂蚁行为或其他因素的变化增加了蚂蚁种子传播的补丁连接的走廊。蚂蚁的长距离种子传播需要几代人短距离传播事件的积累,这可能是一种未被充分认识的机制,通过这种机制,走廊增加了植物多样性。
Habitat fragmentation impacts ecosystems worldwide through habitat loss, reduced connectivity, and edge effects. Yet, these landscape factors are often confounded, leaving much to be investigated about their relative effects, especially on species interactions. In a landscape experiment, we investigated the consequences of connectivity and edge effects for seed dispersal by ants. We found that ants dispersed seeds farther in habitat patches connected by corridors, but only in patch centers. We did not see an effect on the total number of seeds moved or the rate ants detected seeds. Furthermore, we did not see any differences in ant community composition across patch types, suggesting that shifts in ant behavior or other factors increased ant seed dispersal in patches connected by corridors. Long‐distance seed dispersal by ants that requires an accumulation of short‐distance dispersal events over generations may be an underappreciated mechanism through which corridors increase plant diversity.
