THE PANDA REVEALED

For many people, the giant panda, Ailuropoda melanoleura, is synonymous with conservation. This gentle, bamboo-munching animal is down to around 2,500 individuals, and a combination of small population size and man-made environmental change, means that it is probably doomed to extinction in the wild. All is not gloom, however: the latest issue of Nature [subscription [...]

HOW THE CAT GOT ITS COAT

Mammalian coat colour remains a mystery. Although we know a lot about the patterns involved, and can guess about some of their adaptive advantages, their genetic bases are largely unknown. Using a mixture of classic pedigree studies and molecular genetics, a new paper in Genetics (abstract only unless you have a subscription) has examined the [...]

THE LEOPARD AND THE MOUSE

These photos were taken early in summer 2009 by photography student Casey Gutteridge at the Santago Rare Leopard Project in Hertfordshire, England. The leopard – a female called Sheena – discovered a visitor in her enclosure:

Intrigued by the mouse, the cat sniffed the visitor:

The mouse didn’t seem too concerned and carried on eating:

Although we generally think of [...]

A PREDICTION ABOUT THE PINE MARTEN GENOME

The European pine marten (Martes martes) is a mustelid – part of the weasel family. There is also a North American relative (Martes americana). They mainly nocturnal and pretty hard to spot. Here’s a rather nice picture of a pine marten, from DJS photography (note its right ear, presumably nibbled in a fight):

On the last [...]

BATS DO BETTER UNDER BRIDGES

In many parts of the world, urban development is providing new roosting sites for bats. Concrete road bridges seem to be a favourite place that bats congregate and rear their young. You might expect that what with toxic fumes, heavy-metal run-off and noise pollution, bats living in these sites would do less well than their [...]

WHY MOLECULAR GENETICS IS IMPORTANT

November 2007
Article from earlier in the year using mtDNA to track the number of whales being sold in markets in Korea They discovered that the number actually being consumed was far greater than the number that was officially reported. Uni/Athens needed to see full article.

COUNTING TIGERS

November 2007
How do you count tigers? This BBC online article suggests the hard way. What about estimating population size through population genetics? Different level of accuracy, I suppose.
Nature magazine article about attempts to preserve the Siberian tiger (Uni/Athens needed to get past abstract).

ALL THAT FROM A TOOTH

November 2007
A tooth found in India suggests that ungulates – hoofed mammals – existed in India before the end of the Cretaceous (ie before the end of the dinosaurs), while the sub-continent was charging across the Indian Ocean towards its current destination. They may even have originated in India. This tooth was found in the lava of the Deccan [...]

FAINTING GOATS

November 2007
This video from Natalie Beresford (First Year). This is actually quite a serious question – these goats have a mutation in a muscle protein that makes them fall down. What human diseases might be related to this? What natural behaviours in other animals look like this?
