Cushion and shrub ecosystem engineers contribute differently to diversity and functions in alpine ecosystems

Prepared by Jian-Guo Chen, Xiao-Fang He, Song-Wei Wang, Yang Yang & Hang Sun

Cushion engineers in the alpine ecosystem in south-western China. The two cushion species shown here (Arenaria polytrichoides and Potentilla articulata) can modify the microenvironment and facilitate the colonization and survival of other species.

Detectability of species of Carex varies with abundance, morphology, and site complexity

Prepared by Jacqueline M. Dennett and Scott E. Nielsen

Carex gynocrates (bog sedge) is a short species with few, thin leaves and a small inflorescence. Sedges with this appearance were the most poorly detected group in our study, whereas tall sedges with wide leaves and a large inflorescence were almost never overlooked.
