We investigate a mutualistic metacommunity where the strength of the mutualistic interaction between species is measured by the extent to which the presence of one species on a patch either reduces the extinction rate of the others present on the sam

We model a metapopulation of predator–prey patches using both spatially implicit or mean-field (MF) and spatially explicit (SE) approaches. We show that in the MF model there are parameter regimes for which prey cannot persist in the absence of pre

The steady states and dynamics of the two Schlogl models on one- and two-dimensional lattices are studied using master equation techniques in tandem with simulations. It is found that the classic bistable behavior of model II is modified to monostabl

Sedimentary rocks have complicated permeability patterns arising from the geological processes that formed them. We concentrate on pattern formation in one particular geological process, avalanches (grain flow) in wind-blown or fluvial sands. We pres

We study, using master equation techniques, the time evolution of the average concentration and fluctuations in the two-speciesn-molecule reactionA+(n-1)X⇌nX in one dimension described by a Glauber-type dynamical lattice model for the specific case

We describe one-dimensional discrete difFusive motion that is driven by a purely deterministic system, the logistic map. We find normal diffusive motion above a critical value k, of the chaotic parameter. At A, i, the diftusion constant D plays the r

What is the difference between randomness and chaos ? Although one can define randomness and one can define chaos, one cannot easily assess the difference in a practical situation. Here we compare the results of these two antipodal approaches on a sp

We calculate the effects of thermal fluctuations, dilution, and a uniform external field on the continuously degenerate ground state of dipolar magnets on the square and honeycomb lattices. In all cases, these perturbations make terms in the free ene
