School Malaise Trap Program Data Published in Open Access Journal, PLOS ONE

Hello #bioSMTP participants (past and present)!

Today, the School Malaise Trap Program Team has exciting news to share with you about your contributions to biodiversity research and the international scientific community.  Quite recently, a research article titled “Exploring Genetic Divergence in a Species-Rich Insect Genus Using 2790 DNA Barcodes” was published in PLOS ONE. The researchers utilized DNA barcode data collected by several School Malaise Trap Program participants to support their research. The Director of Education and Outreach at the Biodiversity Institute of Ontario, Dr. Dirk Steinke, explains the significance of your contributions in a recent blog post entry on his site ( and has allowed us to re-post it below for your convenience:

School DNA Barcodes Published
Participants of the School Malaise Trap program told us repeatedly that perhaps the most important aspect of the project, the one that students regard as particularly exciting, is the fact that they take part in the creation of a valuable public and scientific resource. They know their work will have a lasting impact. In case there are people that had any doubts that school data would actually be used in science let me point you to a new paper published just yesterday. Research colleagues in Norway analysed data of the chironomid genus Tanytarsus:
We explore the quality of DNA barcodes to delimit species in the diverse chironomid genus Tanytarsus (Diptera: Chironomidae) by using different analytical tools. The genus Tanytarsus is the most species-rich taxon of tribe Tanytarsini (Diptera: Chironomidae) with more than 400 species worldwide, some of which can be notoriously difficult to identify to species-level using morphology. Our dataset, based on sequences generated from own material and publicly available data in BOLD, consist of 2790 DNA barcodes with a fragment length of at least 500 base pairs. A neighbor joining tree of this dataset comprises 131 well separated clusters representing 121 morphological species of Tanytarsus: 77 named, 16 unnamed and 28 unidentified theoretical species. 


Chironomids are notoriously common in Malaise trap collections. It comes to no surprise that a global search for data records will reveal some school samples. However, to my knowledge this is the first time such a result makes it into a research paper. In total the study includes 47 samples from Canadian schools. And here we go – congratulations to the following schools. Your data have just made it into PLoS ONE.
