Threatened status of neglected and underutilised Jatropha (Euphorbiaceae) species endemic to Mexico
Jatropha curcas is the best known species from the genus, an oilseed crop used for biodiesel production. It deserves attention as more species show similar oil content, phytochemical properties, or as a genetic resource in J. curcas breeding programs. The closest species to J. curcas show restricted distributions and are...Christensen, Cecilie ; Seal, Charlotte ; Rico-Arce, María de Lourdes

Progress, challenges and opportunities for Red Listing
Despite its recognition as an important global resource for conservation, the International Union for Conservation of Nature's (IUCN) Red List of Threatened Species only provides assessments of extinction risk for a small and biased subset of known biodiversity. A more complete Red List can better support species-level conservation by indicating...Bachman, Steven ; Field, Richard ; Reader, Tom ; Raimondo, Domitilla ; Donaldson, John …

The climatic challenge: Which plants will people use in the next century?
More than 31,000 useful plant species have been documented to fulfil needs and services for humans or the animals and environment we depend on. Despite this diversity, humans currently satisfy most requirements with surprisingly few plant species; for example, just three crops – rice, wheat and maize – comprise more... -

Biogeography, phylogenetic relationships and morphological analyses of the South American genus Mutisia L.f. (Asteraceae) shows early connections of two disjunct biodiversity hotspots
The Andes is recognized as one of the most biodiverse places on Earth, promoting in its uplift process a series of recent rapid diversification events in different biotic groups like birds, mammals, insects and vascular plants. The uplift of the Andes during the Cenozoic acted as a barrier for many...
