http://aims.fao.org/aos/agrovoc/c_3062e to the spread of the urban, agricultural and livestockfrontier, affecting the availability of shelters and resources for the breeding ofbirds.Despite our knowledge of the influence of anthropic interventions on biodiversity, investigations that show the anthropic effect on natural history of birds, included the breeding phase, are limited. To describethe anthropic effect on nest predation, 108 artificial nests were established in an anthropic intervention gradient in the jurisdiction of Leticia, Amazonas, Colombia.The 38 nests that were predated, sixwerein the site with the least anthropic intervention, 15 in the intermediate intervention site and 17 in the site with the highest intervention.In particular, the effect of changes in the vegetation cover mediated by anthropic disturbance on bird nests is assessed, expecting that denservegetation coveraround the nestwill positively affect the nest success. Variables associated with the structure of the vegetation near the nests (e.g., Coverage around the nest, low vegetation cover, canopy opening), showeda significant positive relationship with the destination of the nest. This research suggests that the ongoing urbanization process (e.g., house construction and roads) in the Amazon region influences loss of artificial nests, and that changes in the structure of the vegetation mediated by the degradation of natural covers could play a fundamental role in the predation of nests.Keywords:Forest, Experiments, Urbanization.

RESUMEN: Las coberturas de los bosques naturales están cambiando por el avance de la frontera urbana, agrícola y ganadera, afectando la disponibilidad de refugios y recursos para la reproducción de algunas aves. A pesar del avance en el conocimiento del efecto de las intervenciones antrópicas sobre la biodiversidad, son limitadas las investigaciones que evidencien el efecto antrópico sobre la historia de vida de las aves, incluida la reproducción. Para describir el efecto antrópico sobre la depredación de nidos, se establecieron 108 nidos artificiales en un gradiente de intervención antrópica en la jurisdicción de Leticia, Amazonas, Colombia. De los 38 nidos que fueron depredados, 6 fueron en el sitio con menos intervención antrópica, 15 en el sitio de intervención intermedia y 17 en el sitio con mayor intervención. En particular, se evalúa cómo los cambios en la cobertura vegetal mediadas por las intervenciones antrópicas afectan la incubación de las aves, esperando que una mayor cobertura vegetal alrededor del nido, aumentara su probabilidad de éxito. Se encontró que las variables asociadas a la estructura de la vegetación cercana a los nidos (e.g. Cobertura a un metro alrededor del nido, Cobertura vegetal baja, Abertura de dosel), mostraron una relación significativa y positiva con el destino del nido. Esta investigación sugiere que procesos de urbanización (p. ej. Construcción de casas y carreteras) presentes en el contexto de la región amazónica, influyen en la pérdida de nidos artificiales de aves, y que cambios en la estructura de la vegetación mediados por la degradación de las coberturas naturales podrían jugar un papel fundamental en la depredación de nidos. |
