I’m delighted to announce that lab member Raphaël Royauté successfully defended his PhD yesterday…. and he did it with grace, maturity, and poise. The defence was fair, but tough, and Raphael was able to show his breadth and depth of expertise on the broad topic of behaviour in arthropods.
Raphaël’s thesis was titled “Factors influencing behavioural variation in apple orchard populations of the jumping spider Eris militaris (Araneae: Salticidae)” and the during the defence, he was asked (not by me, remarkably!) to offer a ‘tweet’ of the his thesis. Here it is, coming in at almost exactly 140 characters.
So, his research looked at behavioural syndromes in this remarkable jumping spider: Raphaël collected spiders in apple orchards, maintained them in a laboratory and ran them through a battery of behavioural test. He defined behaviours, looked at correlations among these behaviours (sometimes called ‘personality’), and how these traits varied during the development of individuals, consistency of these behaviours and whether behaviours differed depending on whether the spiders came from insecticide-free on insecticide-treated orchards. Raphaël also looked at the direct effect of sub-lethel effects of insecticides on behaviour and will soon be publishing the ways that insecticides mess up their personalities.
Raphaël has really done incredible work – but looking back, I should not be surprised. Soon after he arrived in the lab we worked together on a short project about the activity of spiders right after snowmelt, at at that point, I was impressed with his intellectual curiosity, drive and motivation, and overall approach to scientific research.
After that first project, Raphaël came back to McGill to work on a PhD with me and Dr. Charles Vincent as co-supervisors. And now, many years later, he is now successfully defended a PhD. What a marvellous journey, and I can honestly say that I’ve learned far more from Raphaël than he could have learned from me.
Good luck Raph! (And you’ll be missed in the lab)
