The species-area relationship and evolution | Daniel Lawson

; | Date: |
13 Dec 2004 | Subject: | Populations and Evolution | q-bio.PE | Abstract: | Models relating to the Species-Area curve are usually defined at the species level, and concerned only with ecological timescales. We examine an individual-based model of co-evolution on a spatial lattice based on the Tangled Nature model, and show that reproduction, mutation and dispersion by diffusion in an interacting system produces power-law Species-Area Relations as observed in ecological measurements at medium scales. We find that co-evolutionary habitats form, allowing high diversity levels in a spatially homogenous system, and these are maintained for exponentially increasing time when increasing system size. | Source: | arXiv, q-bio.PE/0412024 | Services: | Forum | Review | PDF | Favorites |
