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… (More)
Mahogany (Swietenia macrophylla, Meliaceae) is the most valuable and intensively exploited Neotropical tree. No information is available regarding the genetic structure of mahogany in South America,… (More)
Fine-scale spatial genetic structure (SGS) in natural tree populations is largely a result of restricted pollen and seed dispersal. Understanding the link between limitations to dispersal in gene… (More)
Many tropical tree species occupy continental expanses of rainforest and flank dispersal barriers such as oceans and mountains. The role of long-distance dispersal in establishing the range of such… (More)
Since no universal codominant markers are currently available, dominant genetic markers, such as amplified fragment length polymorphism (AFLP), are valuable tools for assessing genetic diversity in… (More)
Mahogany (Swietenia macrophylla King [Meliaceae]) is the most valuable hardwood species in the neotropics. Its conservation status has been the subject of increasing concern due to overexploitation… (More)
Illegal logging is one of the main causes of ongoing worldwide deforestation and needs to be eradicated. The trade in illegal timber and wood products creates market disadvantages for products from… (More)
In theory, conservation genetics predicts that forest fragmentation will reduce gene dispersal, but in practice, genetic and ecological processes are also dependent on other population… (More)
Twelve polymorphic microsatellite markers were developed for the Brazil nut (Bertholletia excelsa), one of the most valuable non-timber forest products from the Amazon, based on enrichment protocol.… (More)
The Bactec MB9000 (MB) continuous monitoring system was compared to the Septic-Chek AFB (SC) for the detection of Mycobacterium species from all patient sources. A total of 1485 specimens were… (More)
