We developed the equation of $\alpha_{c,f} = \alpha_{0,f,intra} \, CON + \alpha_{0,f,inter} \ (1-CON) - \alpha_t \, t_f + \alpha_e \, t_c + \alpha_d \,\vert t_c-t_f \vert$ along with the basal area of each competing species in the competition index to show the parameters are directly related to community weighted means of the different trait variables as:
and $N_i$ is the number of species in the local neighbourhood of the tree $i$. Note that the indices $p$ and $s$ respectively for plot and data set are not shown here for sake of simplicity.
## Derivation of $\rho$ for a Lotka-Volterra model based on Godoy \& Levine[@Godoy-2014]
Chesson[@Chesson-2012] proposed to estimate the stabilising niche difference based on the per capita growth rate of a rare invader into a population of a resident species. Godoy \& Levine[@Godoy-2014] used this method on an annual plant population model. This approach can be explained using the Lotka-Volterra model:
The criterion for invasion of species $i$ into a resident community of species $j$ (at equilibrium population $\overline{N_j} = \frac{1}{\alpha'_{jj}}$) is:
\begin{equation}
(1 - \frac{\alpha_{ij}}{\alpha'_{jj}})
\end{equation}
Thus if $\frac{\alpha_{ij}}{\alpha'_{jj}} <1$ invasion of $i$ into $j$ is possible (and similar approach for $j$ into $i$).
Stable coexistence between species $i$ and species $j$ thus requires
$\frac{\alpha'_{ij}}{\alpha'_{jj}}$ and $\frac{\alpha'_{ji}}{\alpha'_{ii}}$ to be smaller than 1. Chesson[@Chesson-2012] then defined the average
