Good mimics have the costumes and the acting skills

There are lots of ways to fool an observer, and I mentioned quite a few in my post on the Cafe Scientifique talk that I gave in September. However, one aspect that I didn’t mention there was “behavioural mimicry” – where an animal acts like another animal in order to fool a potential predator or prey.  This sort of behaviour has been reported plenty of times in the field, but has never been studied in a systematic way. My collaborators over at Carleton (led by Tom Sherratt and Heather Penney, who collected the data as part of her MSc thesis work) and I have just published a paper (press release here) which provides just such an overview, and tests a few key evolutionary hypotheses along the way.Read More »

Why are there imperfect mimics?

A few colleagues and I recently had a paper published in Nature on “A comparative analysis of the evolutionary of imperfect mimicry”. Those of you fortunate to have a Nature subscription can read the paper here.  Alternatively, you can email me and I’ll send you a copy.  Unfortunately, I can’t make the paper available due to issues with copyright from Nature (see elsewhere for details of scientists’ love-hate relationship with publishers…) but I can summarise the paper here.
