Effects of selective logging on a bird community in the Brazilian Atlantic forest
(Cooper Ornithological SocLawrenceEUA, 1999)
Bird species of black water inundation forests in the Jau National Park (Amazonas state, Brazil): their contribution to regional species richness
(Kluwer Academic Publ, 2000-02-01)
We compared the relative contribution of blackwater inundation forest (igapo) and unflooded (terra firme) forest for regional bird species diversity in the lower Rio Negro region. For analyses of habitat preference we used ...

Diversity of understory birds in old stands of native and Eucalyptus plantations
(2015-01-01)
We compared the vegetation structure between old (>70 year) stands of planted diversified native forests and stands of Eucalyptus tereticornis embedded in a mosaic of Eucalyptus stands. We then tested for differences in ...
Bird-mediated selection on fruit display traits in Celtis ehrenbergiana (Cannabaceae)
(Evolutionary Ecology Ltd, 2014-08)
Background: In mutualistic interactions of fleshy-fruited plants and seed-dispersing birds, dispersers act as natural selection agents on fruit display traits. Bird-mediated phenotypic selection on maternal and seed level ...
Fruit selection by Andean forest birds: influence of fruit functional traits and their temporal variation
(Wiley Blackwell Publishing, Inc, 2016-09)
Fruit selection, i.e., the consumption of fruits disproportionately to their availability, results from the interaction between diet preferences and ecological factors that modify them. We assessed the importance of ...
Can achene selection in sunflower crop–wild hybrids by pre-dispersal seed predators hasten the return to phenotypically wild sunflowers?
(Springer, 2015-04-16)
Bird attack is a serious limitation to sunflower yield in several regions of the world, but it could also cause selection. The wild Helianthus annuus, naturalized in several regions of the world, hybridizes with the crop ...
Functional extinction of birds drives rapid evolutionary changes in seed size
(2013-05-31)
Local extinctions have cascading effects on ecosystem functions, yet little is known about the potential for the rapid evolutionary change of species in human-modified scenarios. We show that the functional extinction of ...
