Ecologia Poblacional Y Reproductiva De Cordia Bellonis Urb. (boraginaceae), Una Especie En Peligro

Resumen del Libro

Cordia bellonis Urb. is a rare and endemic shrub located in the Maricao and Rio Abajo Commonwealth Forests. No individuals were registered in the Susua forest. The species grows on serpentine and limestone soils, at edges of roads and highways, with good light exposure, on shallow and humid soils, on relatively inclined slopes and in areas of moderately acid to neutral pH levels. Sexes are spatially segregated but the population is symmetrical. The proportion of sexes was not significantly different from 1:1. The flowering and fructification are synchronous and seasonal events. The flowering period occurs in the rainy season whereas the fructification begins at the end of the rainy season and continues until the dry season. The species is visited mainly by generalist insects like moths (Noctuidae), flower flies (Syrphidae) and Apis mellifera L. Most seedlings were found under the canopy of the females and their recruitment occurs in the dry season. (Abstract shortened by UMI.)
