Bangka Slow Loris Nycticebus bancanus

This species was last reported from the wild in 1937. If the Bangka Slow Loris is still alive then the burning of their habitat and conversion to agriculture (especially to palm oil plantations) is their greatest threat. Bangka slow lorises are also threatened by exploitation and the illegal wildlife trade. However, this risk will be less since Bangka is relatively isolated from other Indonesian islands.

Buffy-tufted-ear Marmoset Callithrix aurita

These enchanting and charismatic tiny monkeys have a distinct “gothic” appearance. They live deep in the forests of a tiny area of Brazil. Buffy-tufted-ear Marmosets are also known as buffy tufted-ear mamosets or the white-eared marmosets. They are New World monkeys living in a geographically isolated region in the Atlantic coast that has been decimated for palm oil, soy and cattle ranching agriculture and mining.

Kaapori Capuchin Cebus kaapori

The Kaapori capuchin is on a knife-edge of survival – they are critically endangered. In 2017 their population had been decimated by 80% due to deforestation for agriculture including soy, cattle grazing and palm oil. Part of the gracile genus of capuchin monkeys, Kaapori (also known as ka’apor) capuchins have longer limbs in comparison to their body size. They weigh around 2-3 kilos. Compared to other capuchin species, they have rounder skulls and musculature supporting their teeth and jaws means that they can’t open hard nuts. To get at insects living inside of trees they break branches with their teeth and hands in order to reach the ants inside. They also smash snails against trees in order to crack their shells open.

Chimpanzees once helped African rainforests recover from a major collapse

Most people probably think that the rainforest of central and west Africa, the second largest in the world, has been around for millions of years. However recent research suggests that it is mostly just 2,000 or so years old. The forest reached roughly its modern state following five centuries of regeneration after it was massivelyContinue reading “Chimpanzees once helped African rainforests recover from a major collapse”

Primates are facing an impending extinction crisis – but we know very little about what will actually protect them

From lemurs to orangutans, tarsiers to gorillas, primates are captivating and sometimes unnervingly similar to us. So it’s not surprising that this group of more than 500 species receives a great deal of research and conservation attention. But despite this effort, more than 60% of primate species are threatened with extinction mainly due to humanContinue reading “Primates are facing an impending extinction crisis – but we know very little about what will actually protect them”

Bonobos can inspire us to make our democracies more peaceful

Bonobos, sometimes called the “forgotten ape” due to their recent discovery and small numbers, titillate the democrat’s imagination. Before the 1970s, certain primatologists thought bonobos were strange chimpanzees because females govern in this primate society. Frans de Waal, the primatologist and popular writer, has done much to explain the fascinating lives of these “peace-loving apes”Continue reading “Bonobos can inspire us to make our democracies more peaceful”

Research: Small room for compromise between oil palm cultivation and primate conservation in Africa

Research by the Joint Research Centre of the European Commission found that although oil palm cultivation represents an important source of income for many tropical countries, its future expansion is a primary threat to tropical forests and biodiversity. In this context, and especially in regions where industrial palm oil production is still emerging, identifying “areasContinue reading “Research: Small room for compromise between oil palm cultivation and primate conservation in Africa”

Contagious yawns show social ties in humans and bonobos

Penny Orbell, The Conversation Most of us have experienced the overwhelming urge to yawn in response to another person yawning – but we’re not the only species to do this. Research published in PeerJ today shows bonobos – our closest evolutionary cousins – also experience “yawn contagion”, and, as in humans, the effect is influencedContinue reading “Contagious yawns show social ties in humans and bonobos”

IUCN redContinue reading “Santa Marta White-fronted Capuchin Cebus malitiosus”

For primates, having a mother helps them learn social skills

Carla Litchfield, University of South Australia Wild bonobos, like all Great Apes, spend long childhoods with their mothers, learning the skills they need to function as socially and emotionally stable members of their community. But orphaned bonobos at sanctuaries don’t have that kind of upbringing. Can they still learn the skills they need to getContinue reading “For primates, having a mother helps them learn social skills”
