Colonization of Brazil by the cattle egret


Recommended Posts

In recent years the cattle egret (Bubulcus ibis) has colonized American continent. Invasive species are a worldwide problem and studies are devoted to assess the damage they cause to local species populations. Thus, the process of colonization of a new territory that has continental dimensions such as Brazil offers an excellent opportunity to examine how non-native species disperse, adapt and survive. A new study of the colonization patterns of the cattle egret in Brazil, published in the open access journal NeoBiota, offers a new take on the study of alien species.

A new study of the colonization patterns of the cattle egret in Brazil offers a new take on the study of alien species. It aims to present how the invasive species colonized this great new area, to compare the Brazilian population genetic composition to the native species in Africa and to detect genetic signs of demographic expansion in these two areas.13u2iWgNWDI
