          Abstract

          En muchos agroecosistemas de América Latina las cercas vivas representan un hábitat importante para muchas especies de aves; sin embargo, aún no se conocen cuáles son las características de las cercas vivas y del paisaje circundante que influyen sobre la depredación de nidos en estas estructuras. Utilizando nidos artificiales, se estudió la depredación en 20 cercas vivas de un sistema agro-urbano del centro de México. Los datos de depredación de nidos se relacionaron con variables del hábitat a dos escalas espaciales, local y del paisaje. De los 200 nidos colocados 80 fueron depredados, y no se encontró ninguna relación significativa entre la depredación total y las variables a escala local. A escala del paisaje se observó que la depredación total aumentó en cercas vivas localizadas cerca de áreas cubiertas con vegetación nativa. Se encontró también que los principales depredadores fueron aves, seguidas de carnívoros y roedores.

          In many agro-ecosystems of Latin America, hedgerows are an important habitat for numerous bird species. However, the hedgerow characteristics and those of the surrounding landscape affecting nest predation in these structures are not known. Using artificial nests, predation was studied in 20 hedgerows located in an agro-urban system in central Mexico. Predation data was related with habitat variables at two spatial scales, local and landscape. Out of a total of 200 artificial nests put in place, 80 nests were predated and no significant relationship was found between total predation and local scale variables. At the landscape scale, total predation increased in hedgerows located near remnants of native vegetation. It was also found that birds were the main predators in this landscape, followed by carnivores and rodents.
