许多植物依靠动物传播种子，蚂蚁通常扮演这个角色。我们研究了蚂蚁群落组成的异质性之间的网站，地上和地下觅食公会，或季节之间的预测观察到的种子去除率的变化为12 nonmyrmecochorous新热带先锋树种的巴罗科罗拉多岛，巴拿马。我们还调查了是否蚂蚁与去除种子不同的具体形态特征从较大的蚂蚁社区。我们观察蚂蚁种子的相互作用在缓存，以确定蚂蚁删除12个树种的种子。我们还抽样蚂蚁群落组成放置315陷阱陷阱和160个地下陷阱在5个网站的种子去除率进行了量化。地面蚂蚁群落组成因地点而异，但不随季节变化。蚂蚁组成的网站之间的变化并没有预测在这些相同的网站的种子去除模式。地下蚂蚁社区不同于地上蚂蚁社区，但没有结构的网站或种子缓存类型。最后，移走种子的蚂蚁在形态上与更广泛的蚂蚁群落没有区别。总的来说，我们的研究结果表明蚂蚁群落在相对较小的空间尺度上变化，但表现出高度的功能冗余，为新热带先锋树种提供种子清除服务。
Many plants depend on animals for seed dispersal, and ants commonly fill this role. We examined whether heterogeneity in ant community composition among sites, between above‐ and belowground foraging guilds, or between seasons predicts observed variation in seed removal rates for 12 nonmyrmecochorous Neotropical pioneer tree species on Barro Colorado Island, Panama. We also investigated whether ants associated with removing seeds differed in specific morphological characters from the larger ant community. We observed ant–seed interactions at caches to determine which ants removed seeds of 12 tree species. We also sampled ant community composition by placing 315 pitfall traps and 160 subterranean traps across the five sites where seed removal rates were quantified. Aboveground ant community composition varied by site but not season. Among‐site variation in ant composition did not predict seed removal patterns at these same sites. Belowground ant communities differed from aboveground ant communities but were not structured by either site or seed cache type. Finally, ants that removed seeds did not differ morphologically from the broader ant community. Overall, our results suggest ant communities vary over relatively small spatial scales but exhibit a high degree of functional redundancy in terms of seed removal services provided for Neotropical pioneer tree species.Abstract in Spanish is available with online material.
