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... -

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

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 …
