Madagascar’s extraordinary biodiversity: Threats and opportunities.
Madagascar’s unique biota is heavily affected by human activity and is under intense threat. Here, we review the current state of knowledge on the conservation status of Madagascar’s terrestrial and freshwater biodiversity by presenting data and analyses on documented and predicted species-level conservation statuses, the most prevalent and relevant threats,... -

Madagascar’s extraordinary biodiversity: Evolution, distribution, and use.
Madagascar’s biota is hyperdiverse and includes exceptional levels of endemicity. We review the current state of knowledge on Madagascar’s past and current terrestrial and freshwater biodiversity by compiling and presenting comprehensive data on species diversity, endemism, and rates of species description and human uses, in addition to presenting an updated... -

Tribe Shoreae (Dipterocarpaceae subfamily Dipterocarpoideae) Finally Dissected.
The dipterocarp tribe Shoreae, perhaps more than any other members of this elegant family of often giant emergent trees, is familiar to all who visit the once ubiquitous lowland forests of tropical Asia. Timbers of the genus comprised the bulk of hardwood traded on international markets for thirty years, since...Ashton, P. S. ; Heckenhauer, J.

Diversity and Taxonomy of Cyperus (Cyperaceae) in the Central-West Region of Brazil.
A taxonomic study of Cyperus L. (Cyperaceae) in the Central-West region of Brazil is presented. We examined more than 1300 herbarium specimens. Many of the species were also studied in the field. Our results recognize 59 species of Cyperus in the Central-West of Brazil, including three species endemic to the... -

Trade in Zambian Edible Orchids—DNA Barcoding Reveals the Use of Unexpected Orchid Taxa for Chikanda.
In Zambia, wild edible terrestrial orchids are used to produce a local delicacy called chikanda, which has become increasingly popular throughout the country. Commercialization puts orchid populations in Zambia and neighbouring countries at risk of overharvesting. Hitherto, no study has documented which orchid species are traded on local markets, as... -

Using an Asteraceae checklist to understand collection history, species density and conservation implications: a case study in the state of Alagoas, Northeastern Brazil.
Alagoas is a Brazilian state contained in the area of two large and important phytogeographic domains: Atlantic Forest and Caatinga. Although the presence of these domains possibly indicates a considerable biodiversity, floristic studies in the state are still scarce, especially for the family Asteraceae. In this sense, we developed a...
