Quantifying hunting-induced defaunation As the human population grows and increasingly encroaches on remaining wildlife habitat, hunting threatens many species. Benítez-López et al. conducted a large-scale meta-analysis of hunting trends and impacts across the tropics (see the Perspective by Brashares and Gaynor). Bird and mammal populations were considerably lower in areas where hunting occurred. Although commercial hunting and proximity to roads and urban centers were the most damaging… Expand
Hunting and Forest Modification Have Distinct Defaunation Impacts on Tropical Mammals and Birds
TLDR
Assessment of the effects of three major regional-scale drivers of tropical defaunation, namely hunting, forest degradation and forest conversion, on measures of abundance for tropical mammal and bird species belonging to different dietary guilds and IUCN conservation status groups shows hunting has the most consistent negative impacts on abundances of carnivores, frugivores/granivores, large-bodied species, and species of high conservation importance. Expand
Combined effects of land use and hunting on distributions of tropical mammals
TLDR
These spatially detailed and species‐specific results may support future national and global conservation agendas, including the design of post‐2020 protected area targets and strategies. Expand
Intact but empty forests? Patterns of hunting-induced mammal defaunation in the tropics
TLDR
The pervasive effects of overhunting on tropical mammal populations may have profound ramifications for ecosystem functioning and the livelihoods of wild-meat-dependent communities, and underscore that forest coverage alone is not necessarily indicative of ecosystem intactness. Expand
Quantifying the scale and socioeconomic drivers of bird hunting in Central African forest communities
Abstract Global biodiversity is threatened by unsustainable exploitation for subsistence and commerce, and tropical forests are facing a hunting crisis. In Central African forests, hunting pressureExpand
Habitat degradation and indiscriminate hunting differentially impact faunal communities in the Southeast Asian tropical biodiversity hotspot
TLDR
It is found that functional extinction rates were higher in hunted compared to degraded sites, and that conservation stakeholders should focus as much on overhunting as on habitat conservation to address the defaunation crisis. Expand
Managing subsistence hunting in the changing landscape of Neotropical rain forests
Subsistence hunting has been a vital activity for local people across Neotropical rain forests (NRF). While providing a reliable source of protein, subsistence hunting also reflected the strongExpand
The social determinants and ecological consequences of indiscriminate hunting in tropical Asia
Overexploitation is one of the most prominent threats facing IUCN Red-Listed mammals and birds, particularly in the tropics. Classical bioeconomic models focused on single species have proposedExpand
Combined impacts of deforestation and wildlife trade on tropical biodiversity are severely underestimated
TLDR
The authors parse the relative contributions of deforestation and trapping to declines of native birds in Southeast Asia, finding that the extinction risk of trapped species may be underestimated. Expand
Global extent and drivers of mammal population declines in protected areas under illegal hunting pressure
TLDR
Examination of global research over 40 years provides evidence that illegal hunting is most likely to cause declines of large-bodied species in protected areas of resource-poor countries regardless of protected area conservation status. Expand
A Cross-Site Analysis of Neotropical Bird Hunting Profiles
Subsistence hunting of neotropical birds is common and widespread in the tropical forests of Latin America. Although its sustainability under different scenarios is subject to debate, hunting hasExpand

Effects of Hunting and Fragmentation on Terrestrial Mammals in the Chiquitano Forests of Bolivia
TLDR
It is found that the addition of fragmentation in hunted landscapes negatively affected only two species and positively affected three smaller species, indicating that a failure to explicitly incorporate the effects of hunting into the design of fragmentation experiments can lead to widely different conclusions. Expand
Decoupling the effects of logging and hunting on an afrotropical animal community.
TLDR
Together, logging and hunting shifted the relative abundance of the animal community away from large mammals toward squirrels and birds, and exacerbated decreases in populations of some guilds, but counteracted one another for others. Expand
Extent and ecological consequences of hunting in Central African rainforests in the twenty-first century
TLDR
It is hypothesize that, in the near future, the trophic changes brought about by hunting will have a larger and more rapid impact on Central African rainforest structure and function than the direct impacts of climate change on the vegetation. Expand
Differential impact of bushmeat hunting on monkey species and implications for primate conservation in Korup National Park, Cameroon
Bushmeat hunting is one of the primary threats to many large-bodied vertebrate species in African forests. However, species vary in their degree of vulnerability to hunting. We investigated theExpand
Impacts of roads and hunting on central African rainforest mammals.
TLDR
It is suggested that even moderate hunting pressure can markedly alter the structure of mammal communities in central Africa, with the magnitude of road avoidance increasing with local hunting pressure. Expand

Bushmeat hunting is threatening wildlife populations across west-central Africa, and now poses a greater threat to primates than habitat loss or degradation does in some areas. However, species varyExpand

Bushmeat hunting and extinction risk to the world's mammals
TLDR
An analysis showing that bushmeat hunting for mostly food and medicinal products is driving a global crisis whereby 301 terrestrial mammal species are threatened with extinction, and proposes a multi-pronged conservation strategy to help save threatened mammals from immediate extinction and avoid a collapse of food security for hundreds of millions of people.
