Se cree que la abundancia de las aves frugívoras en diferentes parches de un paisaje está relacionada con la riqueza del recurso fruto. Aunque existe evidencia a nivel de comunidad, esta relación pocas veces ha sido probada cuantitativamente a nivel de especie para aves frugívoras que habitan diferentes tipos de vegetación o etapas sucesionales en un paisaje. Eneste trabajo evalué, en un paisaje neotropical, la relación mensual entre abundancia de especies de aves frugívoras y riqueza del recurso fruto en diferentes tipos de vegetación contiguos. La abundancia mensual de cada especie de ave frugívora no se puede explicar en función de la riqueza de las especies de plantas ornitócoras en fruto por tipo de vegetación. Sólo encontré dos correlaciones positivas de las 42 realizadas (catorce especies de aves por tres tipos de vegetación), lo cual bien podría ser resultado del azar. En estudios de este tipo es posible que se obtenga otro resultado al considerar variables como la abundancia absoluta del recurso fruto (v. gr., número de frutos maduros disponibles en un área) o la riqueza o abundancia de las especies específicas de las que se alimenta cada especie de ave, en vez de la riqueza del recurso por de tipo de vegetación.
It is believed that the abundance of frugivorous birds in a landscape is related to the fruit supply in each vegetation type. Although some evidence for this relationship exists at the bird community level, it has seldom been demonstrated in frugivorous bird species that inhabit different vegetation types or succesional gradients in a landscape. In this study, I assessed the temporal relationships between the abundance of individual frugivorous bird species and the richness of fruiting ornithochorous plant species in different, contiguous vegetation types in a neotropical landscape. Monthly variation in abundance of each frugivorous bird species cannot be explained by the richness of fruiting ornithochorous plant species in each vegetation type. I found only two positive correlations out of a possible 42 (fourteen bird species in three vegetation tvpes), which could easily be due to chanceo In studies of this type, it is possible to obtain different results if the variables are absolute abundance of fruit (e.g., number of ripe fruits in an area) or richness or abundance of specific plant species eaten by each bird species assessed, instead of richness of fruiting ornithochorous plant species by vegetation type.
