Reality check in Borneo - The decline of Borneo's orang utan
population is not just due to recent deforestation but had begun
to occur over 2,000 years. A scientific paper study published in
Plus One journal by a team experts found that the Borneo orang
utans begun experiencing a major demographic decline from about
2,000 years ago based on samples collected in six different
study sites in Sabah and Kalimantan. Researchers from Europe,
South America, and in Borneo have discussed the endangered orang
utan habitat. "The recent loss of habitat and its dramatic
fragmentation has affected the patterns of genetic variability
and differentiation among the remaining populations of orang
utans and increased the extinction risk of the most isolated
ones," Dr Reeta Sharma from Instituto Gulbenkian de Cincia (IGC,
Portugal). "We used orang utans samples collected in six
different study sites in Sabah (Kinabatangan and Danum Valley)
and Kalimantan and genetic markers to identify signals of
population decline," added Sharm
