ZARATE CUEVAS, Lizbeth et al. Reproductive phenology of trees in a mountainous area of western Mexico. Rev. mex. de cienc. forestales [online]. 2022, vol.13, n.69, pp.155-176.  Epub 09-Mayo-2022. ISSN 2007-1132.  https://doi.org/10.29298/rmcf.v13i69.1176.

Knowledge of the flowering and fruiting patterns of tree species is important, given their relationship with pollinators and dispersers and because they are indicative of the best dates for collecting flowers and fruits for taxonomic and reproductive purposes. Therefore, the flowering and fruiting patterns of the tree species of the Las Joyas Scientific Station and adjacent areas in the Sierra of Manantlán in the state of Jalisco were analyzed, and their correlation with precipitation, temperature, insolation, relative humidity and evaporation was researched. Herbarium specimens with flowers and fruits collected from 1985 and deposited in the ZEA Herbarium of the University of Guadalajara were reviewed. The descriptive statistics of the data were performed using histograms. One way variance analysis was performed in search of differences between flowering and fruiting periods and Pearson's correlations in order to determine the relationships between flowering and fruiting and environmental variables. The highest richness of flowering and fruiting species was found to occur during the dry season of the year. The type of vegetation that registered the most species was the cloud forest, a plant community whose flowering and fruiting pattern conforms to the general pattern of all taxa. The richness of flowering and fruiting tree species exhibited a negative and significant correlation with relative humidity and precipitation, the most important environmental variables.
