Limit theorems for the population size of a birth and death process allowing catastrophes
The linear birth and death process with catastrophes is formulated as a right continuous random walk on the non-negative integers which evolves in continuous time with an instantaneous jump rate proportional t...

The supercritical birth, death and catastrophe process: Limit theorems on the set of non-extinction
The skip-free property of the super-critical linear birth and death process with a linear catastrophe component is exploited to obtain an almost sure convergence theorem for the population size without any ext...

Legumes at Loggerheads: Modelling Competition Between Two Strains of Sub-Clover
In essence this paper is a précis of a substantial investigation of deterministic modelling of two strains of sub-clover which interact competitively at the time they set their seed.
