Habitat fragmentation effect on the characteristics of orangutan nest tree selection

One of the steps to prevent orangutan extinction is by increasing habitat connectivity through corridors and reducing fragmentation of landscapes as well as stopping habitat lost.

The Challenges of Conserving Biodiversity: A Spotlight on Southeast Asia

Biodiversity is being lost at a rapid pace, mainly due to anthropogenic pressures from a growing human population. Southeast Asia is a biodiversity hotspot with high species endemism; however, it is

How widespread was the Tapanuli orangutan and what led to its decline

The Tapanuli orangutan ( Pongo tapanuliensis ) is the most threatened great ape species in the world. It is restricted to an area of about 1,000 km 2 of mostly hill forest where fewer than 800

The historic range and drivers of decline of the Tapanuli orangutan

It is demonstrated that historically Pongo tapanuliensis inhabited a much larger area, and across a much wider range of habitat types than now, and how sensitive this species is to the combined effects of habitat fragmentation and unsustainable take-off rates is indicated.

Grouping behavior of Sumatran orangutans (Pongo abelii) and Tapanuli orangutans (Pongo tapanuliensis) living in forest with low fruit abundance

Orangutans in Sikundur were more likely to form parties when fruit availability was higher, but the size of daily parties was not significantly affected by fruit availability, and between‐site differences in sociality seem to reflect differences in average fruit availability.

The distribution and density of Tapanuli orangutans (Pongo tapanuliensis) at potential corridor locations between forest fragments in Batang Toru, North Sumatra, Indonesia

Abstract. Nasution A, Perwitasari-Farajallah D, Utami-Atmoko SS. 2020. The distribution and density of Tapanuli orangutans (Pongo tapanuliensis) at potential corridor locations between forest

It is recommended that government and conservation bodies recognise T&S corridors as a serious and mounting threat to primates and that further research in this area is encouraged.

Tapanuli orangutan endangered by Sumatran hydropower scheme

To the Editor — The Tapanuli orangutan survives today in less than 1,200 km2 of rainforest in northern Sumatra, Indonesia, in an area known as Batang Toru, where it was scientifically discovered1 in

Phylogeny and phylogeography of chelonians from sub-Saharan Africa—A review of current knowledge in tribute to Margaretha D. Hofmeyr

It is shown that phylogeographic and phylogenetic investigations have led to unexpected findings for Pelomedusa, a putatively wide-ranging monotypic terrapin genus, cryptic diversity was revealed, with more than ten species being uncovered.



Newly discovered orangutan species requires urgent habitat protection

Orangutan population biology, life history, and conservation: Perspectives from population viability analysis models

This chapter uses Population Viability Analysis (PVA) to consider the conservation implications of orangutan life history and population biology, and a baseline model that incorporates the best available orangutans life-history data is presented.

Morphometric, Behavioral, and Genomic Evidence for a New Orangutan Species

The status of the Sumatran orang-utan Pongo abelii: an update

The Sumatran orang-utan Pongo abelii is categorized as Critically Endangered on the 2002 IUCN Red List. Although several reports have suggested that the species occurs in the region to the south of

Why do orangutans leave the trees? Terrestrial behavior among wild Bornean orangutans (Pongo pygmaeus wurmbii) at Tuanan, Central Kalimantan

It is concluded that ground use is a natural part of the Bornean orangutan behavioral repertoire, however it remains unclear to what extent food scarcity and canopy structure explain population differences in ground use.

Land-cover changes predict steep declines for the Sumatran orangutan (Pongo abelii)

The results indicate that future deforestation will continue to be the cause of rapid declines in orangutan numbers and it is urged that all developmental planning involving forest loss be accompanied by appropriate environmental impact assessments conforming with the current national and provincial legislations.

Among Orangutans: Red Apes and the Rise of Human Culture

In a richly illustrated narrative, a distinguished biological anthropologist introduces the colorful characters and complex lives of the orangutans who inhabit the rapidly vanishing forests of

Roads to riches or ruin?

A better understanding of the impacts of roads and other infrastructure on the authors' planet, societies, and economies, and more effective planning to ensure that the benefits of infrastructure outstrip its costs is needed.

The Ecological Effects of Linear Infrastructure and Traffic

Roads, railways and utility easements are integral components of human society, allowing for the safe and efficient transport of people and goods. There are few places on earth that are not currently

Bad roads, good roads

Roads greatly influence the footprint of human activity, but they are often constructed with little consideration of their environmental impacts, especially in developing nations. Here, differences
