Summer abundance and activity monitoring of arthropods at Alert, Nunavut

Modified Malaise traps are used to capture surface active and low-flying arthropods. Two 5-trap transects are established in two dominant shorebird foraging habitats that are used during the brood rearing period, i.e. marsh and dry tundra (2 transect/habitat), and run continuously from late June to early August. Traps are emptied every 48 hrs. Arthropods collected are classified to their particular order. Some orders, such as Diptera and Collembola, are further classified to family and separated into size classes.
