dc.description.abstractLa manera en que las especies cercanamente relacionadas segregan su hábitat y los mecanismos que permiten su coexistencia es un problema clave en la ecología de comunidades. Cuando el rango de varias especies se solapa, aquellas que ocupen la misma fracción de un recurso dado deberían diferir en otras dimensiones debido a la complementariedad de nicho o la partición de recursos. En las comunidades de aves, esto ocurre principalmente a través de diferencias en su uso del hábitat. En este trabajo evalué los patrones de segregación de nicho de seis especies de parúlidos Neotropicales (i.e. Cardellina canadensis, Leiothlypis peregrina, Setophaga castanea, S. cerulea, S. fusca y S. pitiayumi) en sistemas agroforestales al norte de la cordillera occidental de Los Andes en el departamento de Antioquia, Colombia. Encontré evidencias de segregación espacial (distribución altitudinal) y alimentaria (distribución vertical, altura y sustrato de alimentación) entre las especies estudiadas que, en conjunto, sugieren patrones de segregación ecológica. El alto grado de solapamiento de nicho en estas mismas variables indica que las interacciones interespecíficas (e.g. competencia) son determinantes para estructurar esta comunidad de parúlidos que coocurren. El gradiente altitudinal (localidad) fue la única de las categorías evaluadas que no presentó solapamiento entre las especies sugiriendo que, de las variables consideradas, esta dimensión espacial puede ser importante para reducir la competencia entre las especies a pesar de sus similitudes ecológicas.

dc.description.abstractThe way in which closely related species segregate by habitat, and the mechanisms that allow their coexistence, is a central question in community ecology. When the ranges of several species overlap (i.e., they are sympatric), those that use the same food resources should differ in other niche dimensions due to niche complementarity or resource partitioning. In bird communities, this primarily occurs through differences in foraging behavior, diet specialization or composition, and habitat use. In this paper, we evaluated how six species of parulid New World warblers (Cardellina canadensis, Leiothlypis peregrina, Setophaga castanea, Setophaga cerulea, Setophaga fusca, and Setophaga pitiayumi) segregate their ecological niches across an elevational gradient of agroforestry systems in the Western Andes of Colombia. We found evidence of elevational and microhabitat segregation for the six warbler species, suggesting patterns of ecological niche partitioning. High levels of niche overlap among these variables indicated that interspecific interactions (e.g., competition) are key for structuring this co-occurring parulid community. In particular, the warblers exhibited a clear distributional pattern across the elevational gradient. This indicates that elevational segregation might be an important dimension in which these species reduce interspecific competition despite their ecological similarity. Our analysis of multiple niche dimensions (i.e., elevational and microhabitat parameters) revealed differential patterns of habitat use that can suggest niche partitioning in ecologically similar species.eng
