A new Coryphoid palm genus from Madagascar
TLDR
Tahina is included within tribe Chuniophoeniceae of subfamily Coryphoideae, based on the strictly tubular imbricate rachilla bracts, the flowers grouped in cincinni with tubular bracteoles, and the stalk-like base to the corolla. Expand
Palaeo-precipitation is a major determinant of palm species richness patterns across Madagascar: a tropical biodiversity hotspot
TLDR
It is found that palaeoclimate exerted a strong influence on palm species richness patterns, with richness peaking in areas with higher LGM precipitation relative to present-day even after controlling for modern environment. Expand
Can we bring Madagascar's critically endangered palms back from the brink? Genetics, ecology and conservation of the critically endangered palm Beccariophoenix madagascariensis
TLDR
It was found that despite critically small population sizes there was considerable genetic diversity within populations, and that ecologically and or geographically distinct populations were genetically distinct. Expand
Contrasting patterns of genetic diversity between two endangered palms with overlapping distributions, Voanioala gerardii (Arecoideae) and Lemurophoenix halleuxii (Arecoideae), from North-east
TLDR
It is found that Voanioala gerardii populations are critically small but contain unexpectedly high levels of genetic diversity, which may indicate as yet undiscovered populations remaining. Expand
New species of Dypsis and Ravenea (Arecaceae) from Madagascar
TLDR
Fourteen new species of palms (Arecaceae) from Madagascar are described and named, based on material collected over the last 15 years, seven are Critically Endangered and seven are Vulnerable. Expand
Comprehensive Red List Assessment Reveals Exceptionally High Extinction Risk to Madagascar Palms
TLDR
It is indicated that 83% of the 192 endemic species are threatened, nearly four times the proportion estimated for plants globally and exceeding estimates for all other comprehensively evaluated plant groups in Madagascar. Expand
The Demographic History of Micro-endemics: Have Rare Species Always Been Rare?
TLDR
A population genetic approach is used to reveal historical demographic decline in the rare endemic flora of Madagascar and shows that it is possible to predict extinction risk from demographic patterns inferred from genetic data and that destructive human influence is likely to have resulted in the very high frequency of narrow endemics present on the island. Expand
Analalava - a palm conservation hotspot in eastern Madagascar.
of Madagascar is well known. Approximately 90% of the 188 indigenous palms species on the island occur in rainforest (Dransfield & Beentje 1995; Rakotoarinivo & Dransfield, submitted), the primaryExpand
Population modelling and genetics of a critically endangered Madagascan palm Tahina spectabilis
TLDR
The models suggest that if the habitat where the species resides continues to be protected the species is unlikely to go extinct due to inherent population decline and that it will likely experience significant population growth after approximately 80 years due to the reproductive and life cycle attributes of the species.
