    I think I misspoke during the talk. Crow asked if heterogeneity could ever give a platykurtic dispersal kernel. I said yes. However, in the simple case of heterogeneity in diffusivity, this is incorrect. Since the kurtosis of the heterogeneous dispersal kernel is given by

    \text{Kurt}(x)=3\left(\frac{\text{Var}(D)}{\bar{D}^2}+1\right)

    And we can never have a negative variance, then heterogeneity can never give a platykurtic kernel. \text{Kurt}(x) will always be at least 3 (that of a Gaussian).
