Similar social behaviour, Similar Genes?

By , July 10, 2018

Happy to report the publication of a new paper from the lab, in collaboration with Drs. Amy Toth (Iowa State) and Laura Beani (Università di Firenze). The paper was led by PhD Candidate Katie Dogantzis, and involved generating new population genomics data for paper wasps and comparing the data to honey bees and bumblebees.  We found that paper wasps and bumblebees have more in common, relative to paper wasps than honeybees, when it comes to adaptive changes in protein coding genes.

Congrats Katie!

New paper out with…. MayB!!!!!

By , June 7, 2018

It always feels good when I get to work with some of my text book heros – the accomplished scientists that you read and idolize at different stages of your academic career.  So, when Dr. May Berenbaum [National Academy Member/Department Heat of Illinois’ Entomology/National Medal of Science winner… i like to say that former President Obama got his photo taken with May] emailed me a year ago to collaborate, i said ‘yes’ immediately! (i also went around telling everyone within a 30 m radius that we were going to be working with MayB!)

The resulting analysis was just published in Insectes Sociaux. Its a fun little paper about how social bees, who have an extreme pollen- and nectar-rich diet have evolved to cope with some of the nasty chemicals that plants use against herbivorous insects

New paper on pesticides and honey bees

By , July 4, 2017

Greetings all,
Our paper on honey bee health near corn crops was published last week in the journal Science. The study was funded by the Government of Ontario. The research team included collaborators from Laval led by Dr. Valérie Fournier, and several zayedlab undergrads that worked with Nadia on this large project.

While normally i would write a little summary, a lot of our findings have been summarized in the news, so you can read about the study at Nature News, Forbes, NPR, AAAS, Metro,LA Times, The Scientist, New Scientist, Washington Post, Radio Canada International, BBC News, The Guardian, The Star, Vice, Scientific American. Also check out the Editor’s Summary, and  Dr. Jeremy Kerr (U. Ottawa)’s Op Ed Story.

New paper – African bee genomes and SNPs

By , December 7, 2016

Happy to report on a recent paper from the lab; Visiting PhD student Samir Kadri and YorkU PhD student Brock Harpur worked together to sequence and discover mutations in Brazilian Africanized honey bee genomes. The work was recently published as an open access article in Scientific Data. Also check out this y-file story on the research. Congrats Samir and Brock!

A new test for ‘killer bees’

By , May 20, 2015

Happy to report that we played an important role in an international effort to develop a new diagnostic test for africanized ‘killer’ bees. Africanized bees invaded the southern US where Canadian beekeepers like to import queen bees. Older tests for telling if a bee is africanized or not are not reliable. We worked closely with Nadine Chapman and Ben Oldroyd from the University of Sydney’s famed social insect lab to develop a very accurate genetic  test. PhD candidate Brock Harpur used our database of over 12 million mutations in the honey bee  to pick diagnostic mutations that differ between African and European bees.

The study was recently published online in Molecular Ecology Resources. Also see the York U and UoSydney press releases too!

New edited book on Sociogenomics!

By , April 8, 2015

Happy to report the publication of a new volume of Advances in Insect Physiology that i co-edited with Dr. Clement Kent, titled Genomics, Physiology and Behaviour of Social Insects. The book launched last week, and contains ten fantastic (in my slightly humble and obviously very biased opinion!) chapters on genomics-empowered research on the biology of social insects.  Clement and I strived for diversity and so we got honey bees, bumble bees, wasps, ants (ok… partial coverage on the ants) termites, and aphids… oh my! Check out the nice cover and table of contents here and below.AIP 48 front and back

It was a lot of work, but we had a group of fabulous and dedicated authors that really helped with meeting the very tight deadlines… Many of us worked over the December break and new years ; I remember doing some last min. editing on Christmas day, before the turkey!  Clement and I are very proud of the result, and we hope you enjoy it too!

New paper on the immune system of honey bees

By , August 29, 2014

Happy to announce a new publication from the lab on the immune system of honey bees in PLoS ONE. The study explored the genetic relationship between the honey bee’s innate and social immune system. The study was authored by PhD candidate Brock Harpur, with strong contributions from Anna Chernyshova and Arash Soltani – two honours thesis students in my lab (2012). MSc Candidate Nadia Tsvetkov and NSERC USRA students Mohammad and Jack (Zhixing) were instrumental in completing the field-work .

A general summary of the research will follow in a few days…
