   Notes: x is the vector of seed dispersal distances, p refers to shape parameters, s refers to scale parameters, τ is the location parameter of the Cauchy distribution, λ is the rate parameter of the exponential distribution, and μ and σ refer to the mean and standard deviation (of the logarithm, in the case of the lognormal distribution).
