%0 Journal Article %T Simulation of geographical trends in Chowdhury ecosystem model %A Klaus Rohde %A Dietrich Stauffer %J Quantitative Biology %D 2005 %I arXiv %X A computer simulation based on individual births and deaths gives a biodiversity increasing from cold to warm climates, in agreement with reality. Complexity of foodwebs increases with time and at a higher rate at low latitudes, and there is a higher rate of species creation at low latitudes. Keeping many niches empty makes the results correspond more closely to natural gradients. %U http://arxiv.org/abs/q-bio/0505016v1
