Genetic Variation in Natural Mahogany Populations in Bolivia from Bolivia. We sampled seeds from individual maternal trees in four mahogany populations separated by as much as 100km. Data were analyzed based on estimated maternal genotypes and on randomly drawn progeny arrays from known mothers. The analysis indicated that mahogany in this part of its range

Hurricane Damage to Mahogany Crowns Associated with Seed Sourceibbean. In 1989, when the trees were 26 years old, Hurricane Hugo damaged three of the stands in Puerto Rico and St. Croix, U.S. Virgin Islands. Four months after the storm, tree diameters were measured, and the percentage of the crowns of trees removed by the storm was estimated. Nearly 4 years lat

Photosynthetic Response of Hybrid Mahogany Grown Under Contrasting Light Regimesonments with low (6% of full sun), medium (33% of full sun), and high (80% of full sun) light. The saplings showed wide variation in height growth in all environments. We measured photosynthetic response to light and CO. as well as chlorophyll fluorescence characteristics to determine if physiologic

Comparative Analysis of the Nutritional Status of Mahogany Plantations in Puerto Rico soils under different climates in Puerto Rico. Species performance differed markedly according to water availability. Big-leaf mahogany and the hybrid survived and grew at higher rates in the wetter northeastern sites, and small-leaf mahogany was more successful in the drier southwestern sites. We

Growth-, Water-, and Nutrient-Related Plasticity in Hybrid Mahogany Leaf Development Under Contrastiere measured over 417 days. The seedlings showed strong reductions in relative growth rates under low light, but maintained a positive carbon gain, indicated by continuous biomass accumulation under these conditions. Light intensity seemed to affect more markedly the growth of individuals with the l

Regeneration, Growth, and Sustainability of Mahogany in México’s Yucatán Forestss (hurricane blowdown, fire, or bulldozer clearing). More than 50% of adult big-leaf mahogany trees had survived a severe hurricane, leaving 2.8 seed trees ha.. After fire, 29% to 100% of adult mahogany trees survived, leaving an average of 1.4 seed trees ha.. Thirty or more years later, postdisturb
