What is the mean α richness for these samples? What is the γ richness of these four samples? What is the β richness among these samples?
1. Schmitz (1998) found that trait-mediated indirect interactions (TMII) were stronger than density-mediated indirect interactions (DMII) in a spider-grasshopper-grass system. Rinehart et al. (2017) ran a similar experiment with ladybeetles (predator) – scale insects – cordgrass . The plot shows the density of the prey over time. Does it show evidence for a trait-mediated effect […]
