A considerably extended two-dimensional version of the famous Lovelock–Watson model for geosphere–biosphere interactions (“Daisyworld”) is employed to investigate the impact of habitat fragmentation. The latter is dynamically modelled through the standard percolation process first...

Aggregation by particle-cluster interaction of type r−α leads to tenuous growth products with continuously tunable fractal dimension. By using α = 2.7, aggregation clusters are generated with scaling behavior (mass scaling, capacity dimension and fjord structure) similar to the one observed...
