Litter Mixture Interactions at the Level of Plant Functional Types are Additive

  title={Litter Mixture Interactions at the Level of Plant Functional Types are Additive},
  author={Bart Hoorens and Martin Stroetenga and Rien Aerts},
It is very difficult to estimate litter decomposition rates in natural ecosystems because litters of many species are mixed and idiosyncratic interactions occur among those litters. A way to tackle this problem is to investigate litter mixing effects not at the species level but at the level of Plant Functional Types (PFTs). We tested the hypothesis that at the PFT level positive and negative interactions balance each other, causing an overall additive effect (no significant interactions among… CONTINUE READING
