The genetic diversity of forest tree species in French Guiana
The reproductive phenology of six tree species, Dicorynia guianensis , Vouacapoua americana , Eperua grandiflora , Carapa procera, Virola michelii and Chrysophyllum sanguinolentum, has been monitored in the Paracou stands over several years. A large variation of flowering rates exists among the species and from year to year. The tallest trees bloom and fruit more frequently than the smallest. T...
متن کاملSpecies Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)
Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...
متن کاملStrong density- and diversity-related effects help to maintain tree species diversity in a neotropical forest.
Intraspecific density-dependent effects in the Barro Colorado Island (Panama) study area are far stronger, and involve far more species, than previously had been suspected. Significant effects on recruitment, many extremely strong, are seen for 67 out of the 84 most common species in the plot, including the 10 most common. Significant effects on the intrinsic rate of increase are seen in 54 of ...
