How, in the animal world, a daughter avoids mating with her father: Paternal 'voice' recognition

"The study, led by Sharon E Kessler, finds that the grey mouse lemur (Microcebus murinus) – a small-brained, solitary foraging mammal endemic to Madagascar – is able to recognize paternal relatives via vocalizations, thus providing evidence that this is not dependent upon having a large brain and a high social complexity, as previously suggested.

Because grey mouse lemurs are nocturnal solitary-foragers living in dense forests, vocal communication is important for regulating social interactions across distances where visibility is poor and communication via smell is limited. Though the mouse lemur shares sleeping sites with other mouse lemurs, it forages alone for fruit and insects. It is a particularly interesting species with which to study vocal paternal recognition because, in the wild, females remain in the same area of birth and cooperatively raise young with other female kin. Males do not co-nest with their mates or young and provide no paternal care, which limits opportunities for familiarity-based social interactions. Thus, vocalizations are likely to be important – particularly for avoiding inbreeding.” (keep reading)

10 Stunning Lemurs You've Never Heard Of

"If you conjure up a mental image of a lemur, what does it look like?

The chances are good that your mental picture has a grey body, a white face with black eye-fur, and a long, black-and-white banded tail: a ring-tailed lemur, or Lemur catta. These lemurs are the most well-known species of lemur, and are featured in everything from movies and television to children’s toys and cereal boxes.

Ring-tailed lemurs are appealing and interesting, of course: they love to sunbathe, and males daub their tails with scent to participate in so-called “stink fights.”

However, many lesser-known lemur species are just as fascinating as the ring-tailed lemur (and, sadly, often much more endangered). Read on to learn more about some of Madagascar’s magnificent lemur species.

Fuck Yeah Lemurs readers have probably heard of most of these species, but you may still find it interesting!

Female Lemurs Benefit From Multiple Mates, Study Suggests
by Jennifer Welsh

While it may not be as socially acceptable among humans, a female choosing to take multiple mates is a common phenomenon in the animal kingdom. But why the practice of polyandry (a female having more than one male mate at a time) is so prominent is still a mystery in most species.
Most theories predict that taking multiple mates would be risky for a female without adding benefits. However, new research finds that in gray mouse lemurs, a type of small primate from Madagascar, healthy females seek out multiple mates in the few hours of one night they are receptive to mating every year. These multiple mates must confer some kind of benefit to the females, though exactly how they benefit is unknown.
“Males get benefits from mating with multiple females, because they can impregnate multiple partners,” study researcher Elise Huchard, of the German Primate Center in Göttingen, told LiveScience. “In most species, females only have a few oocytes [eggs], so mating with multiple males will not increase the number of offspring they will have.”…

Who Says Animals Don’t Enjoy Themselves? - NYTimes.com

"Two ring-tailed lemurs, perhaps a pair, perhaps just two guys out to catch a few rays, sit side by side tilted back as if in beach chairs, their white bellies exposed, knees apart, feet splayed to catch every last drop of the Madagascar sun. All they need are cigars to complete the picture.

There’s a perfectly good evolutionary explanation for this posture. Scientists use the term “behavioral thermoregulation” to describe how an animal maintains a core body temperature. But as the animal behaviorist Jonathan Balcombe points out in his exuberant look at animal pleasure, “The Exultant Ark,” they are also clearly enjoying themselves. A scientist through and through, Dr. Balcombe can’t help giving the study of animal pleasure a properly scientific name: hedonic ethology.” (continued)

Smells like a lemur | Duke Lemur Center

"Eau d’ Lemur is a perfume so unique that the only way to appreciate it is to come for a visit and experience it yourself. As I spent countless hours leading tours, cleaning enclosures, and collecting lemur behavioral data, I wondered why lemurs are so particularly odoriferous. What was the function behind all the fragrance?" (more)

Richard Branson Plans to Introduce Lemurs Into His Caribbean Islands

Sir Richard Branson is looking to relocate lemurs from zoos to Moskito Island (one of his private islands in the BVI of the Caribbean). But how will this affect the native flora and fauna?

""Maybe [Sir Richard] has got some people to say it is alright - but what else lives on the island, and how might they be affected?" asked Simon Stuart, chair of the International Union for the Conservation of Nature’s Species Survival Commission (IUCN SSC). "It’s pretty weird - I would be alarmed about it and would want some reassurances."

Dr Stuart suggested the project could contravene the IUCN’s code for translocations - designed to prevent the repetition of disastrous events such as the introduction of rabbits and cane toads to Australia. Among other things, it says that translocations should never happen into natural ecosystems.”

"The island’s geographic isolation created a wonderland of biological richness. Now population pressures and political turmoil speed the plunder of its rosewood, minerals, and gems." An informative, if wholly depressing, article about Madagascar’s current ecological issues.
