Genetic variation within and among 11 natural populations of Pterocarpus macrocarpus Kurz. from different forest habitats in Thailand was examined by starch gel electrophoresis of 18 loci coding for 11 enzymes. The species possesses a high level of isozyme variation. The percentage of polymorphic...

Discusses methods for measuring and monitoring different components of biodiversity in tropical forests. Considers the conservation of biodiversity in tropical forests including the use of criteria and indicators, the zonation concept of management, the use of buffer zones, and extractive...
The reproductive output of Shorea siamensis, a widespread dipterocarp tree, was assessed in relation to disturbance and tree density at three sites in western Thailand during the 1996 and 1997 flowering seasons. The locations were similar except in disturbance history, which was reflected in decr...

The mating system in 11 natural populations of Pterocarpus macrocarpus Kurz in Thailand was investigated based on the mixed mating model using 16 isozyme markers. Single-locus outcrossing rates (tm) ranged from 0.719 to 0.959. Both ts and tm revealed a geographic pattern with western populations ...

A framework for a priori estimation of the expected sampling variances of the Shannon-Weaver and the Simpson indices of species diversity is developed by the introduction of the most probable relative species abundance distribution (MOPSAD). MOPSAD gives the prior probability of a species' relati...

Habitat fragmentation reduces the size and increases the spatial isolation of plant populations. Initial predictions have been that such changes will be accompanied by an erosion of genetic variation and increased interpopulation genetic divergence due to increased random genetic drift, elevated ...
