Xiaobin Pan has published his last research titled “Relating functional traits within and across species to the stabilization of grassland productivity” at Journal of Ecology. This study explores how the characteristics of plants influence the stability of ecosystems over time. It shows that fast-growing species tend to be less stable, while the way species differ from each other matters more as communities become more diverse. In simple communities, very different species behave more independently, but in more diverse systems, interactions between species play a bigger role. Overall, the work highlights that understanding ecosystem stability requires looking not only at plant traits, but also at how many species coexist and how they interact.
Figure legend: Relationships between functional trait dissimilarity and temporal correlation among species pairs across species richness levels, using (a) specific leaf area (SLA) and (b) leaf dry matter content (LDMC). Colours represent different levels of species richness. Solid and dashed lines indicate significant (p < 0.05) and non-significant (p > 0.05) relationships, respectively.
