| contents | A fragmented landscape reduces the impact of interspecies
connectivity, leading to higher diversity levels than otherwise
possible in a connected landscape. Reconnecting a previously
fragmented landscape initiates an extinction event, preferentially
weeding out more highly connected species. A sequence of
fragmentation-coalescence events will drive the ecosystem to higher
levels of diversity in a ratchet-like effect, than if the landscape
continuously remained connected. |
