FREITAS, Leandro and BOLMGREN, Kjell. Synchrony is more than overlap: measuring phenological synchronization considering time length and intensity. Rev. bras. Bot. [online]. 2008, vol.31, n.4, pp. 721-724. ISSN 1806-9959. http://dx.doi.org/10.1590/S0100-84042008000400017.
The degree of flowering and fruiting synchronization is believed to have ecological and evolutionary relevance at several scales. Here we discuss some measures that have been used to estimate synchrony and propose an index that incorporates both the entire length of an individual phenophase and variation in the number of flowers or fruits over that time period. This new index describes more accurately the phenological synchrony among individuals and populations.
