- Abstract: 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 : We combined observations of seed removal by ants with a characterization of the above‐ and below ground ant communities at five sites on Barro Colorado Island, Panama, to determine if seed removal patterns were associated with local ant community structure. 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. Resumen: Muchas plantas dependen de animales para la dispersión de semillas, y las hormigas regularmente cumplen con este papel. Se examinó si la heterogeneidad en la composición de hormigas entre sitios, entre los gremios que forrajean en el suelo o subterráneamente, o entre estaciones son predictores de la variación observada en las tasas de dispersión de semillas para 12 especies de árboles neotrópicales en la isla de Barro Colorado, Panamá. Además, se investigó si las hormigas que remueven semillas difieren morfológicamente del total de especies en la comunidad. Usando depósitos de semillas con las 12 especies pioneras, se observó la interacción hormiga‐semilla para identificar las hormigas involucradas en dispersión. En los cinco sitios donde la remoción de semillas fue cuantificada, la mirmecofauna fue muestreada usando 315 trampas de caída y 160 trampas subterráneas. La comunidad de hormigas que forrajea en el suelo varió por sitio más no por estación. Sin embargo, esta variación en la composición entre sitios no predice adecuadamente los patrones de remoción de semillas. La comunidad de hormigas subterránea fue distinta de la que forrajea en el suelo, pero estas diferencias desaparecen cuando los sitios son evaluados individualmente. Finalmente, las hormigas que removieron semillas no difieren morfológicamente del total de especies encontradas en la comunidad. En conjunto, nuestros resultados sugieren que las comunidades de hormigas varían en escalas espaciales relativamente reducidas, pero presentan redundancia funcional en términos de los servicios proporcionados en cuando a remoción de semillas para las especies de árboles pioneros neotrópicales. … (more)
