Bison, black flies and more!

From Team Knife:

Our crew managed to get all of our pan, pitfall and malaise traps set on Tuesday, so we’ve spent the past two days conducting aquatic sampling.

On our way our of town on Wednesday, we were treated to an eyeful of local megafauna:

This bison chewed away quite complacently at the side of the road, not bothered in the least by our vehicle parked close by or the “tourists” taking photographs.

Part of the aquatic sampling protocol includes searching the substrate of moving bodies of water for black fly larvae, one of our target taxa.  Yellowknife has proven to be extremely fruitful in this regard:

The waters seem to be generally very productive here; we’ve removed many specimens of caddisflies, stoneflies, mayflies, damselflies and dragonflies doidoing kick sampling and seaches of submerged rocks.

After a morning of sampling in several rivers, tributaries, and streams west of town this morning, our team spent the afternoon with local residents at the Yellowknife Heritage Museum…more on this fun event to follow in another blog post!
