Barcoding the Collembola of Churchill: a molecular taxonomic reassessment of species diversity in a sub‐ Arctic area
Abstract Although their functional importance in ecosystems is increasingly recognized, soil‐dwelling micro‐arthropods are usually poorly known in comparison with their above‐ground counterparts. Collembola constitute a significant and species‐rich component of the soil biodiversity, but it remains...

| Summary: | Abstract Although their functional importance in ecosystems is increasingly recognized, soil‐dwelling micro‐arthropods are usually poorly known in comparison with their above‐ground counterparts. Collembola constitute a significant and species‐rich component of the soil biodiversity, but it remains a woefully understudied group because of the taxonomic impediment. The ever‐increasing use of molecular taxonomic tools, such as DNA barcoding, provides a possible solution. Here, we test the use of this approach through a diversity survey of C ollembola from the vicinity of C hurchill, M anitoba, C anada, and compare the results with previous surveys in the same area and in other sub‐ A rctic regions. The systematic barcoding campaign at C hurchill revealed a diverse collembolan fauna consisting of 97 species‐level MOTU s in six types of habitats. If all these MOTU s are confirmed as species, this richness would be far higher than prior records for A rctic C anada and could lead to reconsider the actual diversity of the group in A rctic environments. |
