Role of detritus in a spatial food web model with diffusion
Andrzej Pękalski, Janusz Szwabiński
One of the central themes in modern ecology is the enduring debate on whether there is a relationship between the complexity of a biological community and its stability. In this pa…
How bad is to be slow-reacting ? On the effect of the delay in response to a changing environment on a population's survival
Ioana Bena, Michel Droz, Janusz Szwabinski +1
We consider a simple-model population, whose individuals react with a certain delay to temporal variations of their habitat. We investigate the impact of such a delayed-answer on t…
Extinction risk and structure of a food web model
A. Pȩkalski, J. Szwabiński, I. Bena +1
We investigate in detail the model of a trophic web proposed by Amaral and Meyer [Phys. Rev. Lett. 82, 652 (1999)]. We focused on small-size systems that are relevant for real biol…
Complex population dynamics as a competition between multiple time-scale phenomena
Ioana Bena, Michel Droz, Janusz Szwabinski +1
The role of the selection pressure and mutation amplitude on the behavior of a single-species population evolving on a two-dimensional lattice, in a periodically changing environme…
Monte Carlo simulations of the inside-intron recombination
Stanislaw Cebrat, Andrzej Pekalski, Fabian Scharf
Biological genomes are divided into coding and non-coding regions. Introns are non-coding parts within genes, while the remaining non-coding parts are intergenic sequences. To stud…
Species Numbers versus Area in Chowdhury Ecosystems
D. Stauffer, A. Pekalski
For a fixed number of food levels on a lattice, the Chowdhury model for ecosystem is simulated and found to give a number of different species which approaches exponentially a plat…
