Can we trust? Yes, we can trust estimates of species turnover, but estimates of changes in species richness are less reliable. Our new article in the Journal of Ecology: doi.org/10.1111/1365... @journalofecology.bsky.social @iavs5.bsky.social

Estimating belowground decomposability is still a challenge due to methodolgical barriers. Thus, we investigated the effect of experimental (i.e. drought-induced) and natural senescence and associated traits on the decomposability of roots and rhizomes of four Carex species.

Group of "trait ecologists" published a large paper on the state of the art of the discipline in Ecological Monographs. doi.org/10.1002/ecm.... - There are four authors in the team from our group, including the leading author, Francesco de Bello.
Scheme representing and connecting the eight SFs (shortfalls) considered in this review. See also Table 1. We distinguishtraits sensu stricto from specific response functions (SRFs) and specific effect functions (SEFs) as, respectively, the potential responsiveness ofspecies to given environmental conditions and the potential effect on given ecosystem functions. For graphical purposes, we representdifferent species (from 1 to n) belonging to different branches of a (unresolved) phylogenetic tree. We represent trait variability acrossindividuals within a species as black circles with varying sizes depending on their values. A similar approach is used to represent SRF,fitness, and SEF values (respectively gray circles, gray squares, and white circles). Abiotic and biotic filtering is represented as a dotted lineby which certain organisms either become part of, or not, of a local community, based on their trait values. The overlap between trait andSEF values (represented by the mathematical overlap symbol) controls community effects on ecosystems and other trophic levels. The studyof these connections across multiple regions (represented as overlapping images of the scheme for “Region” 1 to n) is the basis of the globalscaling related to SF 8. The drawing of the world was taken from Freepik.com.
