Invertebrates (spiders, insects and slugs) were collected weekly using pitfall traps at four sites near the Arctic LTER at Toolik Field Station, Alaska. Traps were placed along transects in shrub (shrub-dominant) and open (tussock-dominant) tundra sites. Pitfall traps were placed for 48-hour intervals once per week from early June until mid-July 2010. Collected invertebrates were counted and identified to class (all invertebrates), order or family (for some of the most common families collected).

Arthropods (spiders and insects) were collected three times during the 2013 summer using pitfall traps and vacuum sampling in plots fertilized with Nitrogen and Phosphorus for 24 years, and in control plots, in an experiment established near Toolik Field Station, Alaska. Pitfall traps were placed for 48-hour intervals; vacuum samples were taken in a 1m2 area. Collected invertebrates were counted and identified to order or family.
