We recently submitted two preprints to BioRxiv — there is of course a lot of debate (see here and here) around posting your papers to preprint servers such as this, prior to peer review.  It will be interesting to go through the full process firsthand, then decide if we’ll ever do it again…

A few research programs I’m involved in are featured in an At Guelph article — find it here.  The School Malaise Trap Project it discusses, which begins classroom visits Feb 26, has a newly minted website.

My name was dropped, as were the details of a couple of projects (here and here) I worked on with Leland Humble, in Friday Feb 24th’s edition of the National Post.  You can find the article here.

My poster for the upcoming Barcode of Life conference in Adelaide can be downloaded here.  It’s co-authored by Leland Humble at the PFC in Victoria, Canada.  The abstract is the following:

BARCODE-FACILITATED INVENTORIES ELUCIDATE THE INFLUENCE OF A NATIVE PEST OUTBREAK ON THE MOTH DIVERSITY OF A PONDEROSA PINE FOREST SYSTEM

The recent outbreak of mountain pine beetle and related bark beetles (Dendroctonus spp.) in Western Canada is the most extensive and severe epidemic on record. The consequences of the death of most mature overstory pine trees have been well-studied for birds and other vertebrates intricately tied to the resource pulse, but very little has been done to determine what effect the severe change in habitat is having on comparatively neutral residents.  To this end, we investigated the ecological consequences of the outbreak on resident biotic communities by measuring its effect on a species-rich component, the macro-moths (Lepidoptera). We employed DNA barcoding for rough sorting and species identification of nearly eleven thousand specimens to inventory eight ponderosa pine stands in British Columbia that differed widely in attack by Dendroctonus bark beetles. We determined that rarified species richness for the heavily impacted sites was significantly lower than that of the less impacted sites. Moreover, the linear regression analysis of site attributes and diversity estimates revealed that approximately 85% of the variance in species diversity is explained by ponderosa pine mortality.  Macro-moths have a proven record as indicators of habitat integrity and their perceived depression in species richness may therefore be representative of the larger biotic system.  The ecological consequences of increased pest outbreaks cannot be ignored when other natural and human-induced agents of disturbance are likewise increasing.

I was recently notified of this: our article ‘DNA barcodes for 1/1000 of the Animal Kingdom‘ is one of the top ten most cited Biology Letters articles for 2010.  Here’s one good paper that cited it, a recent PLoS ONE paper by Axel Hausmann and colleagues.

One more PLoS ONE paper online

Another chapter from my thesis came out in PLoS ONE recently.  It’s a brief study that compiles and assesses a nearly complete barcode library for the geometrids of BC (for a great overview of this family in BC, see p75 of Scudder and Cannings 2007).  If you’re curious, the only species on our checklist that we didn’t successfully barcode was Hydrelia brunneifasciata (Packard)).  Grab the open-access article here or from my ‘publications’ page, and the reference is as follows:

deWaard, J.R., Hebert, P.D.N., and Humble, L.M.  (2011).  A comprehensive DNA barcode library for the looper moths (Lepidoptera: Geometridae) of British Columbia, Canada.  PLoS ONE 6: e18290.

I successfully defended my dissertation on Dec 16, 2010 and have since submitted the revised thesis.  Check out my exam presentation, programme, or the final thesis, should you be inclined.  An even bigger milestone was reached more recently — Stephanie and I got married on Dec 29 in Oshawa!  You can check out some pictures here.
