Latest research shows the females of some mammal species will have many mates to ensure unclear paternity, so that males can’t resort to killing their rival’s offspring for fear of killing their own. This forces males to evolve to compete through sperm quantity, leading to ever-larger testicles. Scientists find that as testis size increases, infanticide disappears.

New research shows multiple invasive species with the same origin facilitate each other’s ability to colonise ecosystems. By studying how these species interact as well as current population locations, researchers believe that Britain is heading for an ‘invasion meltdown’ of freshwater species from south east Europe.

Scientists have discovered that, when upright, stick insects don’t stick. Instead, they deploy special hairy pads designed to create huge amounts of friction from the tiniest of pressure increases - ensuring that the insects grip but don’t stick.

Previously believed to be only man-made, a natural example of a functioning gear mechanism has been discovered in a common insect - showing that evolution developed interlocking cogs long before we did.

The University Museum of Zoology, Cambridge will be closed to the public from June 2nd 2013. Subject to planning permission, the museum will be undergoing a major redevelopment.

A notebook recording the fauna of Cambridgeshire observed and collected by the Reverend Leonard Jenyns between 1820 and 1849 has been published in full for the first time. A significant naturalist in his own right, Jenyns turned down the offer of a place on HMS Beagle, recommending instead a younger colleague, Charles Darwin.

The traditional belief that fish have short memory spans may not be as true as we thought. Gates scholar Alex Vail is carrying out research that reveals how fish remember other sea creatures and even people.

Set to the stunning backdrop of Cambridge University’s Botanic Garden, the Zoology Department is once again going on a BioBlitz.
