Ten bryophyte communities were sampled for species biomass composition, and for comparison ten higher-plant communities that were similar in physiognomy and in total community biomass. The rather insecure theory in the bryophyte literature was distilled into eight quantifiable predictions, which were tested. For seven, there was no sign of the predicted differences: ie no ...

Four main theories exist. The Stochastic theory sees species assembly as being random. The Humpty Dumpty/Alternative Stable States (ASS) theory suggests that a community may be unable to reassemble itself from its constituent species. The Deterministic theory suggests there will be convergence to one stable state. The Pre-adaptation theory is similar to the Deterministic theory but emphasizes that many species fit the stable state because of characters ...
