125,000 Gorillas Find Haven in Mud Swamp But Still Face Extinction

Conservationists were thrilled last month that thousands of African Western Lowland gorillas - 125,000 by head count estimates - may have found a safe haven in a mud swamp and probably escaped predators.

This could have doubled the number of the endangered primates thought to survive worldwide.

But it never dimmed the fact that the great apes are still heading toward extinction if the activities of mad rebel groups operating with abandon in the forests and mountainous regions of Africa continue unchecked.

Mountain gorillas (Gorilla gorilla beringei) are the worst hit among the three subspecies according to their habitant in different parts of Africa. Others are the Western Lowland Gorilla (Gorilla gorilla gorilla) and the Eastern Lowland Gorilla (Gorilla gorilla grauere).

Man Suffers from 1,415 Diseases; Blames His Gorilla Meat Diet

The average man living in forest-prone areas and who depends on meat from endangered apes and other wildlife for his proteins plays the role of a carrying agent for the hundreds of infectious diseases that humanity is suffering from.

Now experts are warning of the danger to humanity this lifestyle may be posing. Most of these diseases, identified in medical terms as zoonotic because of their ability to jump from animal to man, have been labeled as “emerging infectious diseases” or EIDs.

Over 60 percent of the 1,415 infectious diseases currently known to modern medicine are capable of infecting both humans and animals. Most of these diseases originated in animals and now infect people and include viruses, bacteria, fungi, protozoa and helminths, with 175 pathogenic species associated with diseases considered to be ‘emerging’.

The Nature Conservancy: Scientists Find Monkeys Who Know How to Fish

Long-tailed macaques eat mostly fruit — but when resources are scarce, they’ve been known to get creative with their cuisine. When living near humans, they raid gardens and learn to beg for food. Sometimes they even steal food from inside houses.

Now, for the first time, scientists have observed long-tailed macaques fishing with their bare hands.

Nature Conservancy scientist Erik Meijaard and other researchers are the first to scientifically document this rare conduct. In a recent article published in the International Journal of Primatology, Meijaard and his coauthors say that, while conducting field studies in Indonesia, they have repeatedly observed long-tailed macaques catching fish from fast-flowing rivers.

“This is interesting behavior and some of the first observations of primates catching fish,” says Meijaard, the Conservancy’s senior ecologist in Indonesia.

A Very Hungry Monkey?

In the first sighting back in 1998, researchers describe seeing five female macaques sitting alongside the Ketambe River in the Indonesian province of North Sumatra.

The macaques’ eyes scanned the water. After about three minutes, one of the macaques reached into the river. With her bare hands, she pulled out a fish and quickly ate it. Other macaques watched her — and one even tried unsuccessfully to catch a fish herself.

“Clearly it may raise the question of whether there is some sort of learning going on,” says Meijaard. “If perhaps a couple of generations back, one primate caught a fish and it was subsequently copied.”

Researchers documented a similar sighting in 2006 in a separate macaque population in the Lesan Conservation Area, a Nature Conservancy program site in East Kalimantan, Indonesia. There, on two separate occasions, a macaque was observed swiftly grasping a fish out of the shallows before retreating into the forest with the fish still in its mouth.

While the fishing macaque sighting in Lesan coincided with a time of low fruit availability, Meijaard is hesitant to blame the fishing behavior on resource scarcity or draw conclusions about its meaning.

“It might be nothing more than a hungry monkey who is smart enough to extract nutrients from its environment,” he says.

Protecting Indonesia’s Forests

Meijaard is also the Kalimantan coordinator for the USAID-funded Orangutan Conservation Services Program.

But he says that forests — not macaques or orangutans — are the Conservancy’s real focus.

The Conservancy is fighting an ongoing battle to protect the forests around the Lesan Conservation Area. These forests, which harbor a substantial orangutan population, are slated to be destroyed for agriculture and plantations.

The Conservancy is working around the clock to convince local communities and governments to instead consider their long-term economic needs and put the forests into permanent, sustainable management.

“Macaques and orangutans are neat symbols, but they’re not going to convince people here,” Meijaard says. “What we need is data that shows the microeconomic implications of forest conversion.”

“Depending on the decisions made now, the forest could be around forever, or it could be gone forever by next year.”
