Cryptic species diversity in a widespread neotropical tree genus: The case of Cedrela odorata. [PDF]
Abstract Premise Reconciling the use of taxonomy to partition morphological variation and describe genetic divergence within and among closely related species is a persistent challenge in phylogenetics. We reconstructed phylogenetic relationships among Cedrela odorata (Meliaceae) and five closely allied species to test the genetic basis for the current

Identification of Four Wood Species by an Electronic Nose and by LIBS
This paper presents two complementary methods capable of identifying four wood species (Cedrela fissilis, Ocotea porosa, Hymenolobium petraeum, and Aspidosperma subincanum) both by their volatile organic compounds and by the presence of 10 chemical ...

Light availability changes both trait–trait and trait–growth relations.Crown traits have a stronger effect on growth rates in understory.Physiological traits have a stronger effect on growth rates in gap. Abstract Functional traits have been examined to explain the growth rates of forest communities in different sites.

Forest products are the most used inedible renewable resource, but supplies are finite. It is difficult to know which tree species are in wood products or where they come from. Scientific evidence is needed to support or refute origin and species claims in traded products. We describe the building of a geo‐referenced wood reference collection (xylarium)
