Tool use has allowed humans to become one of the most successful species. However, tool-assisted foraging has also pushed many of our prey species to extinction or endangerment, a technology-driven process thought to be uniquely human. Here, we demonstrate that tool-assisted foraging on shellfish by long-tailed macaques (Macaca fascicularis) in Khao Sam Roi Yot National Park, Thailand, reduces prey size and prey abundance, with more pronounced effects where the macaque population size is larger.

Indio Maíz Biological Reserve, Nicaragua – The howl of a spider monkey that swayed from branch to branch alerted a group of green macaws to our presence and eventually took flight and disappeared i

More than 300 animal species face different degrees of threat in Bahia state.

Pipelines, roads, railways and transmission lines cause severe habitat fragmentation in the Amazon rainforest.

Pune: The Kyasanur Forest Disease (KFD) or monkey fever has spread to newer areas in the state.

Chefchaouen - "If nothing is done, this species will disappear within 10 years," warns a poster on Ahmed Harrad's ageing 4x4 showing Morocco's famed Barbary macaque monkey.

The social brain hypothesis posits that social complexity is the primary driver of primate cognitive complexity, and that social pressures ultimately led to the evolution of the large human brain. Although this idea has been supported by studies indicating positive relationships between relative brain and/or neocortex size and group size, reported effects of different social and mating systems are highly conflicting.

Researchers set up cameras on the ground, in the understory and even climbed very tall trees to attach cameras in the canopy.

Nonhuman primates, our closest biological relatives, play important roles in the livelihoods, cultures, and religions of many societies and offer unique insights into human evolution, biology, behavior, and the threat of emerging diseases. They are an essential component of tropical biodiversity, contributing to forest regeneration and ecosystem health. Current information shows the existence of 504 species in 79 genera distributed in the Neotropics, mainland Africa, Madagascar, and Asia.

Just like humans, monkeys in zoos are not eating enough fruits and vegetables. This may have led to them having "humanized" gut flora.
