Competition for Dispersal in Ant-Dispersed Plants
Science, 1981Two closely related and coexisting plants (Chenopodiaceae) of the Australian arid zone are adapted for seed dispersal by ants. These facultatively perennial shrubs persist in saltbush communities largely as a result of highly directional dispersal to ant mounds, where conditions are favorable for establishment and growth.

Good Dispersion, Bad Dispersion
Review of Economic StudiesAbstract We document that most dispersion in marginal revenue products of inputs occurs across plants within firms rather than between firms. This is commonly thought to reflect misallocation: dispersion is “bad”. However, we show that eliminating frictions hampering internal capital markets in a multi-plant firm model may in fact ...

Intercontinental Dispersal III
1952So monotonous is the behavior of plants in dispersal that its students can hardly avoid in the end a feeling of boredom. The same features constantly recur upon the map; the same tracks repeat themselves without end. Soon a point is reached, where the budding phytogeographer unconsciously begins to inquire, why there is seemingly no end to the same ...

Pollen and seed dispersal among dispersed plants
Biological Reviews, 2005ABSTRACTThe ecological significance of spacing among plants in contributing to the maintenance of species richness, particularly in tropical forests, has received considerable attention that has largely focussed on distance ‐ and density‐dependent seed and seedling mortality.

A general theory is developed for studying changes of a wave train governed by non-linear partial differential equations. The technique is to average over the local oscillations in the medium and so obtain differential equations for the variations in amplitude, wave number, etc.

Abstract The invasion process has been described as a series of stages (Carlton 1985, Williamson and Fitter 1996, Richardson et al. 2000a, Kolar and Lodge 2001). Some have characterized three stages: arrival, establishment, and spread (Williamson 1996, Freckleton et al.
