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.

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

Prepared by 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.

Which results of the standard test for community weighted mean approach are too optimistic?

Prepared by David Zelený

The relationship between the average height of understory herbs (CWM of species height) and the amount of light passing through the forest canopy (quantified by visually estimated cover of trees and shrubs at each site). If the analysis based on CWM approach was done by a standard parametric test, the result is highly significant (P<0.001). However, the result of the standard test is overly optimistic; the max test, which is the correct test for this analysis, returns considerably less exciting P-value (P=0.052).

Imagine a forest, with trees forming a canopy and herbs growing in the understory.…
