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 کاملObject-Based Classification of UltraCamD Imagery for Identification of Tree Species in the Mixed Planted Forest
This study is a contribution to assess the high resolution digital aerial imagery for semi-automatic analysis of tree species identification. To maximize the benefit of such data, the object-based classification was conducted in a mixed forest plantation. Two subsets of an UltraCam D image were geometrically corrected using aero-triangulation method. Some appropriate transformations were perfor...
متن کاملAchievements in forest tree improvement in Australia and New Zealand 9. Genetic improvement of Eucalyptus nitens in Australia
Eucalyptus nitens is the second most widely planted eucalypt species in Australia. The species is principally grown for the production of pulpwood but substantial areas are also managed for solid-wood production. The first large-scale E. nitens progeny trials were established in the 1970s and up to two cycles of breeding have since been completed. Estimates of genetic gains achieved through bre...
متن کاملMultiple evolutionary processes drive the patterns of genetic differentiation in a forest tree species complex
Forest trees frequently form species complexes, complicating taxonomic classification and gene pool management. This is certainly the case in Eucalyptus, and well exemplified by the Eucalyptus globulus complex. This ecologically and economically significant complex comprises four taxa (sspp. bicostata, globulus, maidenii, pseudoglobulus) that are geographically and morphologically distinct, but...
