AbstractA phytolith record from Monte Oscuro, a crater lake located 10 m above sea level on the Pacific coastal plain of Panama, shows that during the Late Pleistocene the lake bed was dry and savanna-like vegetation expanded at the expense of tropical deciduous forest, the modern potential vegetation. A significant reduction of precipitation below current levels was almost certainly required to effect the changes observed. Core sediment characteristics indicate that permanent inundation of the Monte Oscuro basin with water occurred at about 10,500 14C yr B.P. Pollen and phytolith records show that deciduous tropical forest expanded into the lake’s watershed during the early Holocene. Significant burning of the vegetation and increases of weedy plants at ca. 7500 to 7000 14C yr B.P. indicate disturbance, which most likely resulted from early human occupation of the seasonal tropical forest near Monte Oscuro and the development of slash-and-burn methods of cultivation.

Dry Deciduous Forest

The specific gravity of 220 woody species, half of them from a tropical rainforest, half from a tropical deciduous forest was measured. The two groups were compared using a Student t-test. The results show highly significant differences in specific gravity between the species from the two areas: woods from the dry deciduous forest tend to be much heavier than those from the rainforest.

A total of 502 species that belong to 115 families and 301 genera were recorded for Mt. El Cebu and adjacent zones in Polygon V of the El Triunfo Biosphere Reserve. The most speciose families were Orchiclaceae, Fabaceae, Asteraceae, Bromeliaceae and polypodiaceae with 58, 29, 28, 17, and 17 species, respectively. Six plant communities were recognized in the area, among which the cloud forest was the most diverse with 234 species, followed by pine-oak fore st with 150 species, and the tropical rain forest with 127. The oak forest and the tropical deciduous forest were less diverse, with 71 and 39 species, respectively. Only 13 species are included in the Mexican red list of endangered taxa.

A hierarchy of phenological features defines the opportunities for breeding in a population of Cnidoscolus spinosus in a tropical deciduous forest in western Mexico. On any one tree, inflorescences develop in rough synchrony and all present flowers of both sexes. Only female flowers develop at the lowest ranks of ramification but only males develop later. Overlap of the mature period of flowers of both sexes is uncommon on one inflorescence of between inflorescences : individual trees are functionally female or male at any moment. lnter-tree synchrony may thus reduce successful breeding. Asynchrony is achieved in part by differences in the onset of flowering, but also by variance in the lenght of individual flowering cycles. The occurrence of two or three cycles per tree during one season for the population increases its breeding opportunities.

The objective of this study is to assess the biomass allocation pattern s and growth characteristics of three species of Caesalpinia (Leguminosae) from the highly diverse and seasonal Chamela tropical deciduous forest , where the plant growth period is restricted to the rainy season. The studied species, although they are phylogenetically related, presented different biomass al location patterns and RGR during growth, in order to carry out a differential exploitation of resources and to promote their coexistence. There were differences in relative growth rate (RGR), root to shoot ratio (R/ S), net assimilation rate (E), biomass allocation patterns and total biomass and leaf area attained among the studied species. Caesalpinia eriostachys and C. platyloba showed similar growth patterns between them but contrasting with those of C. sclerocarpa. This suggests a temporal uncuopling of their maximum resource demand. RGR was determined to a greater extent by parameters related with E than by parameters related with the specific leaf area (SLA).
