Observaciones fenol©đgicas en el bosque h©ðmedo de premontano de San Pedro de Montes de Oca, Costa Rica
This paper reports 18 months of phenological observations in the forest remnants of San Pedro de Montes de Oca, Costa Rica. This place is located in an area of rich volcanic soils at 1200 m above sea level, with a mean annual rainfall of 2000 mm and a temperature of 20.5ðC. The four phenological characteristics studied (flowering, fruiting, leaf flushing and leaf fall) show a marked periodicity during the year. Flowering and fruiting tend to behave very similar with two peaks during the dry season and beginning of the wel season (January to May) and another in September - October, just after the "veranillos" (July - August, a period of less rainfall). Leaf fall exhibits also a high peak in the dry season, but it diminishes markedly when the wet season begins. Another noticeable period of leaf fall is observed during the period of "veranillos". On the othe band, leaf flushing shows its most active period during the wet season (May to November). The available information permits to get some insights of how tropical forest behave phenologically, but more research is needed, specially on experimental phenology, before a better understanding of the factors and processes involved in the problem can be gained. It is also ponted out in this paper, the necessity of relating the information on phenology to that on reproductive biology in order to get an overall picture of the dynamics of tropical forest ecosystems
