Big-Leaf Mahogany is an important advertisement trees species of the tropics. present debate bearing on no matter if to guard it as an endangered species has been hampered by way of the shortcoming of entire, definitive medical documentation. This booklet experiences on important examine at the ecology of big-leaf mahogany, together with genetic adaptations, regeneration, usual distribution styles and the silvicutural and exchange implications for the tree.

Hamrick and Murawski (1990) used genetic paternity analysis to show that pollen of Platypodium elegans moved, on average, between 368 and 419 m during a 3-year study. Loveless et al. (1998) used a rare marker allele to show that 21% of the pollen received by a group of Tachigali versicolor trees came from at least 500 m away, and Chase et al. (1996) found average pollen movement distances of 142 m in Pithecellobium elegans by using microsatellite markers. Such regular pollen movement would clearly inhibit local population divergence.

Ed. 1988. Biodiversity. National Academy Press, Washington, DC. 3. S. Virgin Islands Sheila E. Ward and Ariel E. Lugo Abstract. The Neotropical mahoganies (Swietenia, family Meliaceace) show great ecological and geographic amplitude. A provenance study, begun by the USDA Forest Service in the 1960s, included 20 genetic sources of the three species of mahogany from México, Central America, and the Caribbean. S. Virgin Islands. We assessed relative amounts of environmental and genetic variation in growth and size traits, survival; insect susceptibility; the segregation of genetic variation among species and among and within populations; and how provenance and species characteristics changed across the different environments.

Canopy position (F. Wadsworth, International Institute of Tropical Forestry, personal communication), shoot borer attack, soil (Marrero 1950b; Medina and Cuevas, Chapter 7, this volume), planting 3. , Chapter 8, this volume; Wang and Scatena, Chapter 12, this volume), and overhead shade (Geary et al. 1973) are all believed to affect mahogany growth. On a local scale, a variety of environmental factors may affect mahogany growth, with complex interactions among them, and with different factors taking precedence on different sites (Geary et al.
