Continued Adaptation of C4 Photosynthesis After an Initial Burst of Changes in the Andropogoneae Grasses
Abstract C4 photosynthesis is a complex trait that sustains fast growth and high productivity in tropical and subtropical conditions and evolved repeatedly in flowering plants. One of the major C4 lineages is Andropogoneae, a group of ∼ 1,200 grass species that includes some of the world's most important crops and...Bianconi, Matheus E ; Hackel, Jan ; Vorontsova, Maria S. ; Alberti, Adriana ; Arthan, Watchara …

The endemic ‘sugar canes’ of Madagascar (Poaceae, Saccharinae: Lasiorhachis) are close relatives of sorghum
Crop wild relatives are important but often poorly known. This is the case for subtribe Saccharinae (Poaceae: Andropogoneae), which includes sugarcane (Saccharum) and sorghum (Sorghum). We present a phylogenetic and taxonomic account of the Malagasy endemic genus Lasiorhachis, previously included in Saccharum. New plastome and nuclear sequences were assembled from...Vorontsova, Maria S. ; Besnard, Guillaume ; Razanatsoa, Jacqueline ; Hackel, Jan

Fire and grazing determined grasslands of central Madagascar represent ancient assemblages.
The ecology of Madagascar's grasslands is under-investigated and the dearth of ecological understanding of how disturbance by fire and grazing shapes these grasslands stems from a perception that disturbance shaped Malagasy grasslands only after human arrival. However, worldwide, fire and grazing shape tropical grasslands over ecological and evolutionary timescales, and... -

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... -
