Taxonomy, phylogeny and conservation of tribe Dalbergieae

The Dalbergioid clade in the subfamily Papilionoideae comprises three subclades: the Dalbergia, Pterocarpus and Adesmia clades. Together they comprise 42 genera and 1,200-1,300 species of trees, shrubs, and herbs inhabiting a wide range of both humid and dry environments. While the clade is pantropical in distribution, about 70% of the species diversity is restricted to Central and South America. The clade is commercially important in that it includes some of the world`s most valuable timber trees, e.g. the rosewoods (Dalbergia, Pterocarpus and Machaerium species). Other taxa provide human and animal food (e.g. species of Arachis, Zornia, Stylosanthes, and Aeschynomene), soil improvement through the fixing of atmospheric nitrogen, medicine (e.g. species of Pterocarpus and Machaerium), and are grown as garden, park and street ornamentals (e.g. Tipuana tipu, Amicia zygomeris and A. glandulosa). Previous studies have largely resolved genus circumscription within the clade but reliable species delimitations are still lacking in some of the most speciose genera, including Dalbergia, Machaerium, and Aeschynomene. Given the ecological and economical importance of the clade, efforts to define “good species” and species extinction risks assessments are urgently needed so that conservation strategies can be put in place to mitigate against habitat loss due to mining, logging, agriculture and urban expansion. The symposium will: 1) share recent advances in taxonomic and systematic efforts to better understand the diversity of the Dalbergieae, 2) share knowledge about the current state of conservation of species belonging to the Dalbergiod clade, and 3) aim to establish an international working group of systematists specialising in the Dalbergieae for future collaborations.
