Comparison of wood properties of planted big-leaf mahogany (Swietenia macrophylla) in martinique island with naturally grown mahogany from brazil, mexiCo and peru
langbour p, gérard J, roda Jm, ahmad fauzi p & guibal d. 2011. Comparison of wood properties of planted big-leaf mahogany (Swietenia macrophylla) in martinique island with naturally grown mahogany from brazil, mexico and peru. Big-leaf mahogany (Swietenia macrophylla) has been harvested and traded since the 16th century. It is highly valued and is used to craft luxury furniture and items. Its n...
متن کاملGenetic structure of Mesoamerican populations of Big-leaf mahogany (Swietenia macrophylla) inferred from microsatellite analysis.
While microsatellites have been used to examine genetic structure in local populations of Neotropical trees, genetic studies based on such high-resolution markers have not been carried out for Mesoamerica as a whole. Here we assess the genetic structure of the Mesoamerican mahogany Swietenia macrophylla King (big-leaf mahogany), a Neotropical tree species recently listed as endangered in CITES ...
متن کاملManagement implications of long-term tree growth and mortality rates: A modeling study of big-leaf mahogany (Swietenia macrophylla) in the Brazilian Amazon
Knowledge of tree age-size relationships is essential towards evaluating the sustainability of harvest regulations that include minimum diameter cutting limits and fixed-length cutting cycles. Although many tropical trees form annual growth rings and can be aged from discs or cores, destructive sampling is not always an option for valuable or threatened species. We used an individual-based popu...
متن کاملThe Importance of Tree Size and Fecundity for Wind Dispersal of Big-Leaf Mahogany
Seed dispersal by wind is a critical yet poorly understood process in tropical forest trees. How tree size and fecundity affect this process at the population level remains largely unknown because of insufficient replication across adults. We measured seed dispersal by the endangered neotropical timber species big-leaf mahogany (Swietenia macrophylla King, Meliaceae) in the Brazilian Amazon at ...
متن کاملIsland Invasion by a Threatened Tree Species: Evidence for Natural Enemy Release of Mahogany (Swietenia macrophylla) on Dominica, Lesser Antilles
Despite its appeal to explain plant invasions, the enemy release hypothesis (ERH) remains largely unexplored for tropical forest trees. Even scarcer are ERH studies conducted on the same host species at both the community and biogeographical scale, irrespective of the system or plant life form. In Cabrits National Park, Dominica, we observed patterns consistent with enemy release of two introdu...
