Patterns, Causes, and Consequences of Anthropocene Defaunation
(2016-11-01)
Anthropocene defaunation, the global extinction of faunal species and populations and the decline in abundance of individuals within populations, has been predominantly documented in terrestrial ecosystems, but indicators ...
Defaunation leads to microevolutionary changes in a tropical palm
(Nature Publishing Group, 2016-08-18)
Many large species have declined worldwide due to habitat fragmentation and poaching. The defaunation of large frugivores and the consequent reductions of seed dispersal services may have immediate effects on plant demography. ...
Defaunation of large mammals leads to an increase in seed predation in the Atlantic forests
(2015-05-04)
Defaunation can trigger cascading events in natural communities and may have strong consequences for plant recruitment in tropical forests. Several species of large seed predators, such as deer and peccaries, are facing ...
Defaunation in the Anthropocene
(Amer Assoc Advancement Science, 2014-07-25)
We live amid a global wave of anthropogenically driven biodiversity loss: species and population extirpations and, critically, declines in local species abundance. Particularly, human impacts on animal biodiversity are an ...
Rewilding defaunated Atlantic Forests with tortoises to restore lost seed dispersal functions
(2017-10-01)
The extinction of frugivores has been considered one of the main drivers of the disruption of important ecological processes, such as seed dispersal. Many defaunated forests are too small to restore function by reintroducing ...
Defaunation affect population and diet of rodents in Neotropical rainforests
(2015-10-01)
Most tropical rainforests have been defaunated of large-bodied mammals and the cascading effects of such extirpations have been poorly studied, particularly on other animals. We used a natural experiment in the Brazilian ...
Seed Predation by Rodents and Implications for Plant Recruitment in Defaunated Atlantic Forests
(2015-09-01)
Rodents are known to perform post-dispersal seed predation in tropical rain forest, but there is little information on the identity of these seed predators and how they select their seeds. Using cafeteria experiments, we ...
No changes in seedling recruitment when terrestrial mammals are excluded in a partially defaunated Atlantic rainforest
(2013-07-01)
One of the most intriguing questions in ecology is how to identify which and how many species will be able to inhabit human-modified landscapes. Large-bodied mammals structure plant communities by trampling, herbivory, ...
Ecological and evolutionary consequences of living in a defaunated world
(2013-07-01)
Defaunation, the loss or population decline of medium and large native vertebrates represents a significant threat to the biodiversity of tropical ecosystems. Here we review the anthropogenic drivers of defaunation, provide ...
