Arnaud Badiane and Javier Abalos have been awarded a travel grant to attend the ASAB Easter Conference 2016 at Aberystwyth University, where they will present talks on the evolution and function of colour signals in lacertids. Both Arnaud and Javi are on the first year of their PhD, congratulations!
We just published a short correspondence in Nature about the scientific consequences of academic language ruling in Spain.
Chris Watson (PhD candidate), Zahida Sultanova (PhD candidate), and Ana Hidalgo (lab manager/technician) join our lab, welcome!
Is the inevitable really inevitable? Why are we doomed to age and die of old (if you’re lucky enough to survive everyday hazards, that is)? Check out my last divulgation piece on Mètode popular science magazine about why we age, featuring an ageless clam and a minute 8-legged super organism, could it be more enticing?
Our new PNAS paper is out! In it, we describe a case of Dr. Jekyll & Mr. Hyde in ants and aphids.
As it turns out, aphids of the species Paracletus cimiciformis come in asexually reproducing twin clonal forms during their radiculous (i.e. root-dwelling) phase. Aphids in general, and this species in particular, have highly complex life cycles (read Ed Young’s hilarious piece in National Geographic about this), and it is in this particular phase when aphids interact with their tending ant, Tetramorium semilaeve. The first of this twin morphs (a greenish morph) chimes well with ants, with whom they trade honeydew for their protection and cleaning services. The second twin morph, though, is as whitish as is devilish. Instead of engaging in this archetypical ant-aphid mutualistic relationship, it mimics ant larvas’ scent to deceive ants into carrying back into their nest, as if they were a stranded larvae. There, they will find refuge from the harshness of winter and feast on ant larva with their stylet, much like a vampire in disguise! This is not only the first known case of aggressive mimicry in aphids, but a fascinating example of plastic aggressive mimicry in that the white and green morphs are clonal copies, and are able to give rise to each other via parthenogenesis; a true case of Dr. Jekyll and Mr. Hyde indeed! Adrian Salazar, the leading author of this paper, has spent almost three years of his PhD studying the relationship between these aphids and their ant hosts in detail, and all that hard work is finally beginning to pay off! Well done Adrian! Stay tuned for the next chapters of this amazing story. In the meanwhile, you can also read about it in New Scientist.
Good news! Arnaud Badiane has been awarded a iMQRES Macquarie Studenship to conduct his PhD co-supervised by Martin Whiting and Pau Carazo.
Our Proc B paper on sex, learning and personality traits in lizards has been picked up by Spiegel!
A new divulgation short article about the evolutionary battle of the sexes has just been published in Mètode.
In collaboration with Ester Desfilis, I have recently quick started ‘Mind your Nature’, a new popular science section in Mètode, an award-winning Spanish Divulgation Magazine. The section will delve into the wonders of Animal Behaviour and explore how its study can help us understand human nature. In our first article, we present the section and outline its aims.
