A study was published several days ago in the journal Proceedings of the Royal Society B examining the social relationships among 13 mountain gorilla groups in Rwadna over 12 years. Typically, mountain gorillas have social groups of 12 to 20 individuals. A group of this size often yields the most diversity in relationships. Mountain gorillas... Continue Reading →
Positive news on the conservation front, where the number of mountain gorillas is over a 1,000 individuals. The survey found the Virunga population has risen to 604 among in 41 social groups... Compared to the 480 individuals counted in the last survey in 2010. The only other place mountain gorillas survive is in Uganda’s Bwindi... Continue Reading →
The Fongoli savanna in southeast Senegal offers a unique ecosystem. Temperatures can rise above 110 degrees Fahrenheit with brush fires sweeping across. The chimpanzees who live on these savannas weren't well understood. Erin Wessling at the Max Planck Institute for Evolutionary Anthropology studied these chimpanzees. She compared these chimps to forest chimpanzees. The Fongoli savanna... Continue Reading →
Behavioral ecologist Helen Morrogh-Bernard of the Borneo Nature Foundation spent 20,000 hours studying 10 Orangutans of in the Sabangau Peat Swamp Forest in Central Kalimantan, Indonesia. Her results are published here. She first observed a female orangutan in 2005 chew a particular plant that isn't part of their diet. That individual and others chew the... Continue Reading →
Up to today, there were two known Orangutan species, both critically endangered. There are about 4,000 more Sumatran orangutans (Pongo abelii) than Bornean orangutans (Pongo pygmaeus) currently living in the Indonesian rainforest. A new orangutan family member, the Tapanuli orangutans (Pongo tapanuliensis), was described in a paper published Thursday in Current Biology. And with less than 800 individuals, that makes...

Researchers from Oxford University, working in Brazil, found new archaeological evidence suggests that Brazilian capuchins have been using stone tools to crack open cashew nuts for at least 700 years. Researchers say, to date, they have found the earliest archaeological examples of monkey tool use outside of Africa. In their paper, published in Current Biology,... Continue Reading →
Footage filmed for a new BBC series 'Gorilla Family & Me' reveals what goes on after dark. A family of endangered gorillas are led into the trees by a silverback known as Chimanuka. The clips capture them making and settling in their nests in and around a tree, the first ever film of this behavior... And at... Continue Reading →
A newborn baby Western lowland gorilla naps in the arms of Frala, its mother at Sydney’s Taronga Zoo. It is about a week old and we don't know if the new addition is male or female.
A New York judge has granted two research chimps the writ of habeas corpus — a move that allows them to challenge their detention. The decision, says Science magazine, effectively recognizes chimps as legal persons, marking the first time in U.S. history that an animal has been given that right.
The first complete genetic map of the mountain gorilla was published several days ago. It is the most extensive genetic analysis of mountain gorillas ever conducted. The importance of it cannot be stressed due to the fact that mountain gorillas are critically endangered. With such small numbers, and the risk of extinction, they are burdened... Continue Reading →
