Museum collections indicate bird defaunation in a biodiversity hotspot
(Revista Biota Neotropica, 2017-01-01)
Ipanema National Forest, southeastern Brazil, once contained 340 bird species. Forest cover suffered for centuries from log exploitation and, as a result, most of the remaining forests are now an impoverished subset of the ...
Spatial pattern of Pindó Palm (Syagrus romanzoffiana) recruitment in Argentinian atlantic forest: the importance of tapir and effects of defaunation
(Wiley; Association of Tropical Biology and Conservation, 2014-11)
Hunting pressure, fragmentation and deforestation have caused global declines in animal abundance, and the consequences for plant communities are poorly understood. Many large‐seeded plants, for instance, depend on large ...
Small vertebrates are key elements in the frugivory networks of a hyperdiverse tropical forest
(2020-12-01)
The local, global or functional extinction of species or populations of animals, known as defaunation, can erode important ecological services in tropical forests. Many mutualistic interactions, such as seed dispersal of ...
Variable impact of late-Quaternary megafaunal extinction in causing ecological state shifts in North and South America
(National Academic Sciences, 2016)
Loss of megafauna, an aspect of defaunation, can precipitate many ecological changes over short time scales. We examine whether megafauna loss can also explain features of lasting ecological state shifts that occurred as ...
Valuing the economic impacts of seed dispersal loss on voluntary carbon markets
(2021-12-01)
Seed dispersal is an ecosystem service strongly affected by the loss of mutualist dispersers, with economic consequences in terms of carbon sequestration and climate change mitigation policies. Especially, large frugivores ...

(Wiley, 2014-10)

Increasing synergistic effects of habitat destruction and hunting on mammals over three decades in the Gran Chaco
(Wiley Blackwell Publishing, Inc, 2020-07)
Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of ...
Mammal defaunation as surrogate of trophic cascades in a biodiversity hotspot
(2013-07-01)
Preserving large tracts of natural habitats is essential to maintain biodiversity. Nevertheless, even large areas may still suffer from less visible impacts such as loss of ecological processes. Because mapping ecological ...
