EEB Seminar: November 14th 2013

The different morphologies of queen and worker ants are the result of environmentally induced differences in gene expression during their development.

Ehab Abouheif will talk on

What have Evo Devo and supersoldier ants taught us about how evolution works?

at 12:30 in Medical School Atrium room 132  [note venue as we needed space for the BIOL-440 class as well]

Abouheif is Associate Professor and Canada Research Chair in Evolutionary Developmental Biology at McGill where he studies the eco-evo-devo biology of ants.

Ehab’s research mission has been to understand how genes and environment  interact to guide development, and in turn how these interactions have evolved to generate diversity both between and within species. Polyphenism – the capacity of the same genotype to generate discrete phenotypes – in the ants is especially dramatic, with comprehensive differences in behaviour, life history and morphology between castes. The Abouheif lab has not only been at the fore in mapping out the gene networks associated with development and caste-differentiation in ants, but does incredibly cool manipulative experiments with environmental induction. In the first of two lectures this week (Thursday’s EEB and Friday’s Departmental), Ehab will explain how his lab has developmentally resurrected super soldiers in species that normally don’t have these sumo-sized fighting machines for colony defence, among other things.

Ehab’s second talk “The Evo Devo of Conflict and Cooperation in Ant Societies” will be on Friday at 10:30AM in BioSci 3110. He would also love to tell anyone interested about his ventures into understanding the Evo Devo of sexual conflict in water striders.

EEB Seminar: November 7th 2013

King of Holland Bird of Paradise, first described in 1875 and painted here by John Gould in the late 1800. This ‘species’ is a hybrid between the Magnificent Bird of Paradise and the King Bird of Paradise.

Paul Martin will talk on

The Paradox of the Birds-of-Paradise: persistent hybridization as a signature of historical reinforcement

12:30 in the EEB Lounge

Paul is an Associate Professor in the Dept of Biology at Queen’s.

Birds of Paradise are way cool. And Paul’s going to tell us why. These birds are native to Australia and New Guinea. There are about 40 species in the family and they are among the most colourful and ornamented birds on the planet. Bright colours and bizarre plumage are often thought to be the signatures of speciation that help to keep closely related species from hybridising but the Birds of Paradise appear to hybridise much more than most birds.

Paul’s lab website is here and some of his recent papers are:
