When Two Silvery Gibbons Meet, It’s Love at First Touch | Conservation International (CI)

13 February 2015

Since gibbons can only survive in the wild as bonded pairs, rehabilitation efforts at the Java Gibbon Center depend on successful matchmaking. Supported by Conservation International and located on the edge of Indonesia’s Gunung Gede Pangrango National Park, the center brought together two rescued gibbons, Jowo (male) and Bombom (female) — creating one of nature’s cutest love stories.

A Novel Reproductive Mode in Frogs: A New Species of Fanged Frog with Internal Fertilization and Birth of Tadpoles

December 31, 2014

Abstract

We describe a new species of fanged frog (Limnonectes larvaepartus) that is unique among anurans in having both internal fertilization and birth of tadpoles. The new species is endemic to Sulawesi Island, Indonesia. This is the fourth valid species of Limnonectes described from Sulawesi despite that the radiation includes at least 15 species and possibly many more. Fewer than a dozen of the 6455 species of frogs in the world are known to have internal fertilization, and of these, all but the new species either deposit fertilized eggs or give birth to froglets.

Indonesian monkeys and trees, new study

Monkey sleep, monkey do: how primates choose their trees

December 31, 2014

Primates don’t monkey around when deciding where to spend the night, but primatologists have had a poor grasp on what drives certain monkeys toward specific trees. Now, two extensive studies of Indonesian primates suggest that factors in selecting trees each evening are site-specific and different for each species—and that some overnight spots result in conflicts between monkeys and humans.

“We have to understand what monkeys need [in order] to sleep to know what we have to protect,” said primate scientist Fany Brotcorne of the University of Liège in Belgium, leader of one of the research teams, in an interview with mongabay.com.

When monkeys choose their evening perch, they weigh more than just comfort. The main factors scientists suspect are safety from predators, distance to feeding grounds, human interactions, insect avoidance, and competition with other primates.

“Primates may be spending up to 12 hours at their sleeping sites, and yet we really don’t know much about them,” said Adrian Barnett of the University of Roehampton, in London, U.K., a primatologist not involved in the new work, in an email to mongabay.com.

The two unaffiliated studies occurred on neighboring Indonesian islands. Brotcorne’s team spent 56 nights in the Bali Barat National Park in Bali studying long-tailed macaques (Macaca fascicularis), a thriving primate species. In West Kalimantan on the island of Borneo, primatologist Katie Feilen of the University of California at Davis followed the sleeping behaviors of endangered proboscis monkeys (Nasalis larvatus) for 132 nights.

Both groups noted the sizes and shapes of trees favored by the monkeys. Brotcorne’s group also measured the distance between sleeping sites and human outposts such as temples, tourist areas, or roads.

The proboscis monkeys returned each night to tall, isolated trees near rivers. The monkeys gather in trees that jut above the canopy to avoid predators and insects, believes Feilen. Predators can’t crawl from tree to tree toward the monkeys if the trees’ branches don’t touch. At the same time, the monkeys’ lofty—and windy—perches help them avoid malaria-ridden mosquitoes that tend to remain within the canopy.

“I think insect and disease ecology plays a bigger role in all these questions of primatology than we are all thinking,” said Feilen.

The long-tailed macaques snoozed away in trees near human-modified areas. Brotcorne suspects food availability was the main factor driving the macaques’ bunk choice. The monkeys scooted closer to a Hindu temple and tourist area where fruit, rice, and crackers abounded during the peak tourist season. The timing of their move also coincided with the start of the dry season and a decline in natural fruit production. The two teams reported their findings side-by-side this month in the American Journal of Primatology.

There is not just one evolutionary force influencing sleeping tree preference for primates, pointed out both lead authors.

“Both papers are significant in that they are showing the importance of sleeping sites in primate ecology,” said Barnett. “What is needed is a collation of data that is sufficiently broad to allow general theories to be put up [about sleeping tree selection].”

The distinct sleeping site chosen by the two species also influences the primates’ interactions with humans. Loggers preferentially remove the tall riverside trees favored by the endangered proboscis monkeys, threatening the species’ habitat, said Feilen. The proboscis monkeys she studied had to contend with deforestation by mining and palm oil companies. Also, local hunters knew where to find the predictable primates.

On the other hand, macaques and humans have competed for space and food in human-modified areas for centuries. But their close contact worries Brotcorne because diseases can cross from monkeys to humans and vice versa. Human food is not the healthiest diet for monkeys, she added.

“If you go to the tourist monkey forests, you will see obese monkeys,” said Brotcorne.

Dutch colonial military torture of Indonesians

Translated from NOS TV in the Netherlands:

Attorney: government liable for torture of Indonesian

Today, 01:48

According to lawyer Liesbeth Zegveld, the [Dutch] government is responsible for the treatment of an Indonesian prisoner by Dutch soldiers during the so-called police actions of the late nineteen forties. According to Zegveld there was “systematic torture”.

She relies on the testimony of the former prisoner, other sources and on the Note on Excesses from 1969, the report of a government investigation into the actions of the Dutch army in the former colony.

The now 86-year-old Mr. Yaseman was captured in 1947 in East Java by soldiers of the KNIL, the Royal Dutch East Indies Army. He was suspected of supporting the movement which sought independence for Indonesia. To get a confession, Yaseman is said to have got electric shocks. Also, he would be forced to drink lots of water, and then interrogators would stand on his belly, the so-called water ordeal.

Five days

According to Zegveld Yaseman suffered serious psychological and physical harm on account of the torture. She is seeking damages. The level of this amount is not clear. Because of the age of her client she wants a response within five days from the Dutch State, reports the Committee Dutch Debts of Honour.

Zegveld has been working longer for victims of the police actions. Like, she advised the widows of men who at that time were executed by Dutch troops. In 2013, they got an apology and compensation.

New bird species discovery in Indonesia


This video from Indonesia is about the newly discovered species Muscicapa sodhii.

From the Birds Alive newsletter:

Sulawesi Streaked Flycatcher (Muscicapa sodhii)

A new species of Muscicapa flycatcher, which has been observed on several occasions since 1997 in Sulawesi, is described. The authors collected two specimens in central Sulawesi in 2012, and based on a combination of morphological, vocal and genetic characters they describe it, named as Muscicapa sodhii, more than 15 years after the first observations. The new species is superficially similar to the highly migratory, boreal-breeding Grey-streaked Flycatcher Muscicapa griseisticta, which winters in Sulawesi.
