Abstract

Many studies reporting the frequency of extra-pair paternity (EPP) have been published. Several hypotheses have been proposed to predict the frequency of EPP, but only a few discuss how habitats could influence the EPP. Although the main hypotheses proposed to explain the variation in the proportion of EPP consider characteristics that can be directly linked to habitat type. Thus, there are signs that there should be a relationship between the frequency of EPP and habitat type. This study aims to survey upon the literature, and based on it, check if there are habitats more prone to the occurrence of EPP. If this relationship is observed, we will bring up and discuss hypotheses that could explain it. The results that will be generated can orient future works in the area of reproductive biology of birds which seek to estimate the frequency of EPP in poorly studied habitats, such as neotropical environments.
