Guess who comes for dinner: other vertebrates in harpy eagle nests
Camera traps recorded several arboreal vertebrate species in or near harpy eagle (Harpia harpyja) nests in commensalistic and even aggressive interactions. The findings are part of the doctoral thesis in Ecology of Helena Aguiar-Silva on resource use by harpy eagles, and have recently been published in the Journal of Raptor Research.

Insularization effects on bird acoustic signals
For his master's project in Ecology, Thiago Bicudo analyzed the effect of lanscape changes on the scructural and temporal parameters of the vocalization of two suboscine birds that are common in primary forests, Lipaugus vociferans and Tyranneutes virescens. The former species is one of the trademark voices in Amazonian rainforests. The study has been recently published in Behavioral Ecology.
