Small collections, great findings: three new species and two new state records for Asteraceae from Brazil

Nordic Journal of Botany, EarlyView.
The BHZB herbarium was founded in 1993 with about 16 787 registers – a number that has to be considered as small when compared to larger herbaria in Brazil. In the BHZB, 97.5% of the vouchers are from the Minas Gerais state (ca 16 372 specimens), with Asteraceae being the best represented family.

Quantifying the contribution of community trait mean and diversity to ecosystem functioning

Oikos, EarlyView.
Hundreds of experiments conducted over the last decades demonstrate a positive relationship between species diversity and ecosystem functions. Following good experimental practice, most of these studies have manipulated species richness artificially by assembling communities randomly. Yet, natural communities along ecological gradients often show niche‐
