Wildlife corridors could offer new hope for orangutans

Researchers from Cardiff University, University of Adelaide, NGO HUTAN, and Sabah Wildlife Department have been looking at ways to improve wildlife corridors in Borneo as a new method of protecting the endangered orangutan.

According to the researchers, more than 80 per cent of the primate’s habitat has been destroyed in the past 20 years due to demand for agricultural land, leaving the remaining forest fragmented, isolating orangutans from one another and resulting in a major threat to their survival.

The study highlights that establishing wildlife corridors that connect fragmented protected areas will allow animals to move freely from one territory to another. This will be beneficial to gene diversity, as it will minimise the negative impact of inbreeding caused by animals being forced to live in small, isolated territories.

Dr Benoît Goossens from Cardiff University’s School of Biosciences stresses that the study should not be limited to orangutans, but can apply to other wildlife species affected by climate change and decreasing, fragmented territories. “In this study we used the orang-utan as a model, but the knowledge gleaned will be useful for other mammal species,” he explains. “The next phase of our research will focus on corridor establishment and enhancement by recovering riparian reserves from oil palm plantations, to inform land managers about best corridor scenarios.”

The research team included Dr Benoît Goossens from Cardiff University, Stephen Gregory, Damien Fordham and Barry Brook from Australia, and Marc Ancrenaz, Raymond Alfred, and Laurentius Ambu from Sabah Wildlife Department.

Borneo rainforests, destruction and conservation

As Borneo deforestation reaches critical level a new protection area is established

According to data published by the Indonesian Forestry Agency, the deforestation in Borneo that occurred between 2000 and 2005 topped 1.23 million hectares, reports ProFauna, the Indonesian organisation for the protection of wild animals and their habitats.

This means that every day around 673 hectares of forest disappeared during that period.

Land conversion into palm oil plantation, timber concessions, industrial plants and mining activities are among the major triggers of the loss.

Despite the threats, there are moves afoot to halt the decline in East Borneo, 450km away from the provincial capital of Samarinda.

The Wehea Protection Forest encompasses an area of 38.000 hectares, 250m above sea level on the eastern part and up to 1750m above sea level on the western part, which means the vegetation varies from lowland forest to montane forest and supports 19 mammals species, 114 birds species, 12 rodents species, 9 primates species, and 59 invaluable types of plants.

One of the most valuable aspects of this forest is its importance to the lives of Bornean orangutans. In 2012, the head of the local environment agency, Didi Suryadi, stated that there were approximately 750 individual orangutans whose lives depend on the sustainability of Wehea forest.

Wehea Protection Forest was established in 2005. The governing board consists of government agencies, indigenous people, educational institutions, and NGOs.

Local people have also formed a ranger team, the members of which are young men of the Dayah Wehea tribe who take turns every day to secure the forest.

Recently, a team from ProFauna visited the Wehea people to establish ties to help with the conservation work.

The secretary of the village, Siang Geah, said: “We are very glad to have ProFauna in Wehea and hope that we can establish a positive partnership in protecting our dwindling forests.”

New spider species discovery in Malaysian Borneo

However, there are also much smaller spiders in Malaysian Borneo.

Students on field course bag new spider species

As a spin-off (pun intended) of their Tropical Biodiversity course in Malaysian Borneo, a team of biology students discover a new spider species, build a makeshift taxonomy lab, write a joint publication and send it off to a major taxonomic journal.

Discovering a new spider species was not what she had anticipated when she signed up for her field course in Tropical Biodiversity, says Elisa Panjang, a Malaysian master’s student from Universiti Malaysia Sabah. She is one of twenty students following the course, organised by Naturalis Biodiversity Center in The Netherlands, and held in the Danau Girang Field Centre in Sabah, Malaysian Borneo. The aim of the one-month course, say organisers Vincent Merckx and Menno Schilthuizen, is to teach the students about how the rich tapestry of the tropical lowland rainforest’s ecosystem is woven.

Besides charismatic species, such as the orang-utans that the students encounter every day in the forest, the tropical ecosystem consists of scores of unseen organisms, and the course focus is on these “small things that run the world”—such as the tiny orb-weaving spiders of the tongue-twistingly named family Symphytognathidae. These one-millimetre-long spiders build tiny webs that they suspend between dead leaves on the forest floor. “When we started putting our noses to the ground we saw them everywhere,” says Danish student Jennie Burmester enthusiastically. What they weren’t prepared for was that the webs turned out to be the work of an unknown species, as spider specialist Jeremy Miller, an instructor on the course, quickly confirmed.

The students then decided to make the official naming and description of the species a course project. They rigged the field centre’s microscopes with smartphones to produce images of the tiny spider’s even tinier genitals (using cooking oil from the station’s kitchen to make them more translucent), dusted the spider’s webs with puffs of corn flour (also from the kitchen) to make them stand out and described the way they were built. They also put a spider in alcohol as “holotype”, the obligatory reference specimen for the naming of any new species—which is to be stored in the collection of Universiti Malaysia Sabah. Finally, a dinner-time discussion yielded a name for this latest addition to the tree of life: Crassignatha danaugirangensis, after the field centre’s idyllic setting at the Danau Girang oxbow lake.

All data and images were then compiled into a scientific paper, which, via the station’s satellite link, was submitted to the Biodiversity Data Journal, a leading online journal for quick dissemination of new biodiversity data, which is currently considering it for publication. Even though thousands of similarly-sized spider species still await discovery, Miller thinks the publication is an important one. “It means we provide a quick anchor point for further work on this species; the naming of a species is the only way to make sure we’re all singing from the same score,” he says.

Field station director Benoît Goossens adds: “This tiny new spider is a nice counterpoint to the large-mammal work we’re doing and having it named after the field centre is extremely cool”. The Danau Girang Field Centre is located in the Lower Kinabatangan Wildlife Sanctuary, a strip of rainforest along Sabah’s major river, squeezed in by vast oil palm plantations on either side. Despite intensive search, the students could not find the new spider in the plantations.

The notion of spiders using ants as bodyguards seems a bit contradictory, but that is exactly what occurs on the tropical forest floors of the Philippines. The jumping spider (Phintella piatensis) strategically nests within the vicinity of the aggressive Asian weaver ant (Ocecophylla smaragdina) as a defense tactic against its main predator, the spitting spider (Scytodes species): here.
