Phenology drives mutualistic network structure and diversity
Ecology Letters (2012) Abstract Several network properties have been identified as determinants of the stability and complexity of mutualistic networks. However, it is unclear which mechanisms give rise to these network properties. Phenology seems important, because it shapes the topology of mutuali...
