Around the world, ecologists are surveying plants in fixed area plots and estimating the cover and abundance of plant species. Photo credit: Fenner School of Environment and Society, The Australian National University.

Our analyses of cover-abundance data are a timely contribution to support the ever-growing volume of plot data that are being compiled into databases.…

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

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

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.

Effects of initial functional-group composition on assembly trajectory in savanna restoration

André G. Coutinho, Monique Alves, Alexandre B. Sampaio, Isabel B. Schmidt & Daniel L. M. Vieira

Results of active restoration in Chapada dos Veadeiros National Park, Goiás, Brazil (14°7’2.54″ S 47°38’30.36″ W). The area on the left side (A) was restored by direct seeding, leading to a vegetation structure more similar to a native Cerrado.
