Descripción
We studied seasonal patterns and the effect of non-native invasive vegetation on bird communities in woodland and adjacent herbaceous-shrub areas in north-east Buenos Aires province, Argentina. Diversity, species richness and density of bird species were higher in spring and summer than in fall and winter in both habitat types. We also found significant between-habitat differences in bird species composition in winter, spring and summer. Seasonal variations were mainly due to changes in the abundance of migrants, whereas bird species segregation to each habitat was mostly explained by non-native vegetation structure. Most species were associated with sites dominated by either Dipsacus fullonum or Gleditsia triacanthos, whereas only four species were associated with high Ligustrum lucidum densities. These results show that despite the dominance of non-native invasive plant species at our study site, vegetation structure is still the main factor structuring bird communities. In addition, some plant species, such as L. lucidum, seem to have a negative effect on bird communities by reducing their diversity, whereas others, such as D. fullonum and G. triacanthos, seem to have a positive effect compared to L. lucidum by providing not only food resources during a great part of the year but also nest sites.
Estudiamos los patrones estacionales y el efecto de vegetación exótica invasora en comunidades de aves de bosque y zonas herbá- ceo-arbustivas adyacentes en el noreste de la provincia de Buenos Aires, Argentina. Diversidad, riqueza y densidad de aves fueron mayores en primavera-verano que en otoño-invierno en ambos tipos de ambiente. Además, encontramos diferencias significativas entre hábitats en la composición de especies en invierno, primavera y verano. Las variaciones estacionales en los atributos comunitarios se debieron principalmente a cambios en la abundancia de aves migratorias, mientras que la segregación de especies en ambos ambientes estuvo explicada en gran parte por la estructura de la vegetación de especies exóticas invasoras. La gran mayoría de las especies de aves estuvieron asociadas a sitios dominados por Dipsacus fullonum ó Gleditsia triacanthos, mientras que sólo cuatro especies estuvieron asociadas a sitios con altas densidades de Ligustrum lucidum. Nuestros resultados muestran que a pesar de la dominancia de vegetación exótica invasora en nuestro sitio de estudio, la estructura de la vegetación es el principal factor que estructura las comunidades de aves. Asimismo, algunas especies exóticas, como L. lucidum, tendrían un efecto negativo sobre las comunidades de aves al disminuir su diversidad, mientras que otras, como D. fullonum y G. triacanthos, tendrían un efecto positivo en comparación con L. lucidum al proveer no solo alimento durante gran parte del año, sino también sitios de nidificación.
