Press Release: Mysterious black leopards finally reveal their spots

Leopards, found from the frozen forests of Russia to the scorching sands of the Kalahari Desert, are the most widely distributed large cat on earth. Their iconic spotted coat has been admired and coveted by humans for millennia. However, in just one region in their vast range, mysteriously the leopards are almost all entirely “black” or melanistic – the Malay Peninsula. This dark colouration sometimes hides the spotted pattern which all leopards have; the spots just don’t stand out clearly in melanistic individuals.

Spotted!

“This is a completely unique phenomenon for leopards, and represents perhaps the only known example of a mammal with almost an entire population completely composed of the melanistic form of the species” says Laurie Hedges, lead author of a study who just published a population density estimate on these animals in the Journal of Wildlife Management.

Melanism is a trait which can be found across many mammal species, and especially in big felids. Though theories, ranging from the explosion of Mount Toba in Sumatra to competition with tigers, have been put forward to explain how this unique melanistic population has come about, scientists are still puzzled…

Publication update 7: What is wilderness?

Ever wondered what people mean when they use the word ‘wilderness’?

To most people, the concept of wilderness generally means pristine, untouched nature, free from the destructive taint of humankind. Would you agree? Many early conservationists subscribed to this idea of wild areas that had been spared the human touch, and therefore their efforts were largely aimed at restoring nature to this perceived original state of being untainted and unchanged (e.g. see Sheil and Meijaard, 2010).

However, the truth is, over the many thousands of years that humans have occupied this planet, there are very few habitats that have not actually been influenced by us in some way or another. Continue reading

Publication update 6: New species await in that jungle yonder

The next time you find yourself near a vast forest far from human settlements with minimal infrastructure in Malaysia, get your camping gear out and spend a few nights in the forests with a group of nature lovers. If you’re lucky, have sharp eyes and walk far enough, you may just find an amphibian or mammal species yet to be discovered by scientists. And if you are really dying to name more new amphibian or mammal species after that special someone, head into the Amazon or Central Africa to improve your chances!

A new study by Giam, one of Rimba’s researchers, found that tropical moist forests of the Neotropics, Afrotropics, and Indomalaya (this includes Malaysia!) are likely harbour the greatest numbers of undescribed species. This paper was recently published in the prestigious international journal, Proceedings of the Royal Society B.

Giam and his colleagues devised a mathematical model of Continue reading
