Local perceptions of the benefits versus negative impacts of weedy grasses in central Madagascar, with a focus on the genus Digitaria.
Les plantes et les pratiques agricoles sont essentielles aux systèmes alimentaires et au bien‐être humain. Une approche de recherche ethnobotanique a été présentée pour mieux comprendre la relation entre les plantes et les activités humaines à Madagascar, où l'agriculture constitue la base de l'économie locale. Cette recherche examine les... -

Four new deciduous species of Hyperacanthus (Rubiaceae: Gardenieae) from western Madagascar: the sofikomba alliance.
The genus comprises 11 species, nine in Madagascar and two in Africa, although many Madagascan species remain undescribed. All Madagascan species of are evergreen trees occurring in humid and semi-humid forest. Four deciduous species occur in the dry forests of northern, western, and southern Madagascar but are unknown to science.... -

Diversity partitioning and community structure of epiphytic bryophytes along an elevational gradient in the north-eastern Madagascar.
Understanding spatial variation in species composition of different communities is key to understanding the processes that generate and maintain biodiversity. The partitioning of diversity into hierarchical scale-related components is an interesting approach to quantitatively defining the overall net biodiversity from hierarchically scaled studies and is a useful method in studies...Marline, Lovanomenjanahary ; Hedderson, Terry A.

Adaptations and evolution of a heritable leaf nodule symbiosis between Dioscorea sansibarensis and Orrella dioscoreae.
Various plant species establish intimate symbioses with bacteria within their aerial organs. The bacteria are contained within nodules or glands often present in distinctive patterns on the leaves in what is commonly referred to as leaf nodule symbiosis. We describe here a highly specific symbiosis between a wild yam species... -

Four new endemic genera of Rubiaceae (Pavetteae) from Madagascar represent multiple radiations into drylands.
The taxonomic positions and phylogenetic relationships of six Pavetteae species endemic to Madagascar were tested with a phylogenetic study of the Afro-Madagascan representatives of the tribe Pavetteae based on sequence data from six markers , , , - , and ITS. The six species were resolved into four well-supported and... -
