New carpenter bee paper from Brock Bee Lab

IMG_1458 Our paper on social organisation and reproductive queues in eastern carpenter bees, is now “pre-published” in manuscript form.  The paper analyses the foraging schedules of  individually marked bees like the one on the photo (which was taken by Jess Vickruck), and is based on data from Chris Course’s MSc thesis.  We will also post the reviews and data sets later in the summer – stay tuned!

Ergonomic skew and reproductive queuing based on social and seasonal variation in foraging activity of eastern carpenter bees. Canadian Journal of Zoology, in press, DOI: 10.1139/cjz-2014-0330.

Jess gets noticed at CSEE2015!


Jess’s talk on the phylogeography of Eastern Carpenter Bees was quite a hit!  It garnered an honorable mention in the student talk competition.

Sweat bee workers that could start their own nests – but don’t

Originally posted on insectessociaux:

Miriam Richards, Associate Editor, Insectes Sociaux

In a recent issue of Insectes Sociaux, we described a rather surprising example of behavioural flexibility in an obligately eusocial sweat bee, Halictus ligatus (Rehan et al. 2013). This is a particularly well studied species that has been the subject of hundreds and hundreds of hours of behavioural observations. As in many eusocial sweat bees, there is considerable evidence in H. ligatus for queen-worker conflict over oviposition rights in Brood 2, a conflict that often results in queen domination, if not monopolization, of Brood 2 egg-laying. Many H. ligatus queens appear to be multiply mated, so relatedness of workers to queen-produced brood is low enough to suggest that workers might often achieve higher fitness through personal reproduction rather than by raising siblings (Richards et al. 1995). Why don’t workers that are bullied by queens and which can’t lay eggs in the natal nest simply…

Extreme Bees in Extreme Environments: A visit with Laurence Packer, bee biologist extraordinaire

1-Laurence IMG_20150320_135945

Before the seminar – some last minute adjustments and email

Last week, Laurence Packer visited our department to deliver a seminar about close encounters with extreme bees.  These bees live in extreme environments, like the Atacama Desert in Chile, usually the driest place on earth.  Many of the bees Laurence has collected, described, and studied in Chile are only a few mm long – if you stood them on their hind ends, they could keep their heads above water even if the average yearly rainfall happened all at once.  It’s amazing that flowers bloom or bees survive in such places.

During the seminar – some interesting flower bits

Laurence was my PhD supervisor at York, long enough ago that we can now count the time in decades.  It’s a delight to still be able to learn from him.  And also a delight to have persuaded him and spouse Gail Fraser to stick around for a day, talking about birds, bees, university politics, and lots of other interesting topics, not to mention a careful evaluation of several Niagara wineries!

More good lab news – NSERC grad fellowship for PhD student, David Awde

IMG_0717 cropped

Everyone in the lab was delighted this week that Dave was awarded an NSERC Post-Graduate Scholarship, which will support him for the next three years.  Dave switched to the PhD programme in September 2015, and this funding is perfectly timed to (eventually) get him to the finish line.  Currently, Dave is working on the first of several planned thesis chapters, comparing the nesting biology of Lasioglossum (Dialictus) laevissimum here at Brock, to populations in other places, as well as to other species of eusocial sweat bees nesting at Brock.
