Summary of distribution fitting to the tail of the empirical distribution of move lengths of male gametes (pooled across presence of female gamete treatments).

Distributions (and estimated parameters) listed in decreasing likelihood of best fit. AIC = Akaike Information Criterion.µ = estimated exponent of power law distributions with probability density function given by f(x) = Cx−µ, for xmax>x>xmin for truncated power law and ∞>x>xmin for power law distribution.λ = parameter for exponential distribution with probability density function given by f(x) = Ae- λx for xmax>x>xmin for truncated exponential and f(x) = λe− λ(x-xmin) for ∞>x>xmin for exponential distribution.
