Arctic arthropod assemblages in habitats of differing shrub dominance
Recent climate warming in the Arctic has caused advancement in the timing of snowmelt and expansion of shrubs into open tundra. Such an altered climate may directly and indirectly (via effects on vegetation) affect arctic arthropod abundance, diversity and assemblage taxonomic composition. To allow...

Recent climate warming in the Arctic has caused advancement in the timing of snowmelt and expansion of shrubs into open tundra.

Over ten weeks of sampling in 2011, pitfall traps captured significantly more arthropods in shrub plots than open tundra plots at two of the three sites.
