Sumatran Orangutans Differ in Their Cultural Knowledge but Not in Their Cognitive Abilities
Animal cultures are controversial because the method used to isolate culture in animals aims at excluding genetic and environmental influences rather than demonstrating social learning. Here, we analyzed these factors in parallel in captivity to determine their influences on tool use. We exposed Sumatran orangutan (Pongo abelii) orphans from tool-using and non-tool-using regions (western swamps...
متن کاملVariasi Genetik Orangutan Kalimantan Timur Berdasarkan DNA Mitokhondria Genetic variations of East Kalimantan Orangutan based on D-Loop mitochondria DNA
Analysis of the variation of D-Loop mtDNA of East Kalimantan orangutan was done to provided the genetic information data from endangerd species in order to support their population conservation efforts. The reason using mtDNA in this research is caused by higher level of mutation ( 5 – 10 trimes) when compared with nuclear DNA and it enable to transmited via maternal transmission without experi...
متن کاملThe Risk of Disease to Great Apes: Simulating Disease Spread in Orang-Utan (Pongo pygmaeus wurmbii) and Chimpanzee (Pan troglodytes schweinfurthii) Association Networks
All great ape species are endangered, and infectious diseases are thought to pose a particular threat to their survival. As great ape species vary substantially in social organisation and gregariousness, there are likely to be differences in susceptibility to disease types and spread. Understanding the relation between social variables and disease is therefore crucial for implementing effective...
متن کاملOrangutan cultures and the evolution of material culture.
Geographic variation in some aspects of chimpanzee behavior has been interpreted as evidence for culture. Here we document similar geographic variation in orangutan behaviors. Moreover, as expected under a cultural interpretation, we find a correlation between geographic distance and cultural difference, a correlation between the abundance of opportunities for social learning and the size of th...
متن کاملNutritional Differences between Two Orangutan Habitats: Implications for Population Density
Bottom-up regulatory factors have been proposed to exert a strong influence on mammalian population density. Studies relating habitat quality to population density have typically made comparisons among distant species or communities without considering variation in food quality among localities. We compared dietary nutritional quality of two Bornean orangutan populations with differing populati...
