Relationship between environmental heterogeneity and birds distribution patterns and richness in two landscapes units of the Paraná River Delta, Argentine

Different factors are involved in determining the diversity and abundance of bird communities. Habitat structure including both the vegetation physiognomy and its spatial variation has been recognized as a major factor in determining distribution and diversity of birds because it influences habitat...

Bird communities Environmental heterogeneity Landscape structure Paraná River Delta Wetlands Different factors are involved in determining the diversity and abundance of bird communities. Habitat structure including both the vegetation physiognomy and its spatial variation has been recognized as a major factor in determining distribution and diversity of birds because it influences habitat selection processes and the availability of critical resources. In this context, the objective of this study was to analyze how environmental heterogeneity influences bird diversity in two landscape units located in the Parana River Delta region. Bird censuses were conducted in order to estimate different community parameters. In addition, in the same census stations we estimated some variables of vegetation structure. Habitat heterogeneity variables were correlated with birds diversity. Differences in environmental variables between both studied landscapes were associated to different birds assemblages. The results show the importance of the spatial variation of the vegetation physiognomy in structuring bird communities in each of the studied areas. In each landscape unit, bird assemblages were differentiated with the considered environmental variables. © The Neotropical Ornithological Society.
