Resumo: | Seed dispersal is one of the principal ecological processes that determine the richness and distribution of plants in tropical forests. Birds play an important role in the zoochoric dispersal of seeds in these forests. The present study investigated the bird-plant interactions involving the ingestion and dispersal of seeds by the birds found in the edge habitat of an isolated forest fragment on the Catuaba Experimental Farm in eastern Acre, in southwestern Brazilian Amazonia. The birds were captured using mist nets, and the seeds were collected from fecal samples obtained during the handling of the animals. These seeds were sorted and identified. The bird and the plant species identified during the study were used to calculate the connectivity and nestedness of the bird-plant interactions. We captured 82 species of birds, with a total sampling effort of 203,180 h.m². Fecal samples obtained from 19 of the bird species contained a total of 2,086 seeds, representing 23 plant species. The interaction network had an intermediate connectance, and significant nestedness. Ramphocelus carbo had the highest importance index and was the bird with the largest number of plant interactions, while Cecropia latiloba was the plant with the highest importance index, followed by Schefflera morototoni. Most of the seed-dispersing birds identified in the present study are generalists found in both the forest core and its edge. The results of the study indicated that the community of generalist-frugivore birds interacts extensively with the plant community of the fragment, providing seed dispersal services that include the deforested areas adjacent to the fragment. |

Las aves juegan un papel importante en la dispersión zoocorica de semillas. El presente estudio investigó las interacciones pájaro-planta relacionadas con la ingestión y dispersión de semillas por las aves encontradas en el hábitat del borde de un fragmento de bosque aislado en la Granja Experimental Catuaba en el este de Acre, en el suroeste de la Amazonía brasileña. Las aves fueron capturadas usando redes de niebla, y las semillas fueron recolectadas de muestras fecales obtenidas durante el manejo de los animales capturados. Las semillas fueron clasificadas e identificadas. Las especies de aves y las especies de plantas se utilizaron para calcular la conectividad y la anidación de las interacciones pájaro-planta. Capturamos 82 especies, con un esfuerzo de muestreo neto total de neblina de 203,180 h.m². Las muestras fecales de 19 de las especies de aves contenían semillas, y recolectamos 2,086 semillas, que representan 23 especies de plantas. La red de interacción tenía una conexión intermedia y anidamiento significativo. El Ramphocelus carbo tuvo el índice de mayor importancia y fue el ave con el mayor número de interacciones de plantas, mientras que Cecropia latiloba fue la planta con el mayor índice de importancia seguido de Schefflera morototoni. La mayoría de las aves dispersoras de semillas identificadas en el presente estudio son generalistas que se encuentran en el núcleo y el borde del bosque. Los resultados indicaron que la comunidad de aves generalistas-frugívoras interactúa ampliamente con la comunidad de plantas del fragmento, proporcionando servicios de dispersión de semillas que incluyen las áreas deforestadas adyacentes al fragmento.Seed dispersal is one of the principal ecological processes that determine the richness and distribution of plants in tropical forests.

The bird and the plant species identified during the study were used to calculate the connectivity and nestedness of the bird-plant interactions. We captured 82 species of birds, with a total sampling effort of 203,180 h.m². Fecal samples obtained from 19 of the bird species contained a total of 2,086 seeds, representing 23 plant species. The interaction network had an intermediate connectance, and significant nestedness. Ramphocelus carbo had the highest importance index and was the bird with the largest number of plant interactions, while Cecropia latiloba was the plant with the highest importance index, followed by Schefflera morototoni. Most of the seed-dispersing birds identified in the present study are generalists found in both the forest core and its edge.
