The propagation of a beneficial mutation in a spatially extended population is usually studied using the phenomenological stochastic Fisher-Kolmogorov-Petrovsky-Piscounov (SFKPP) equation. We derive here an individual-based, stochastic model founded on the spatial Moran process where fluctuations are treated exactly. The mean-field approximation of this model leads to an equation that is differ...

The Moran collection, which has been catalogued over the last two years, has presented the archivist with a number of interesting problems, besides those normally associated with a collection of personal papers. The extensive collection' had been used by Professor Lovell for his biography of Lord Moran while it was still at the family homes and it was following an approach by the archivist of t...

The quarrel between Andreas Libavius and Johannes Hartmann, the subject of a separate monograph by Moran, also assisted in the process. As Moritz's appointee to the first chair of Paracelsian chemistr...
