This taxon has previously been confused with B. nutans var. nutans and has also been erroneously identified in the Mascarenes as B. minutum auct. non Thouars, the latter a Malagasy endemic. Bulbophyllum mascarenense is known from tropical humid native vegetation between 400 and 1200 m elevation, being abundant on the island of Réunion, but less so on Mauritius. Using the Red List Categories and Criteria of the International Union for Conservation of Nature, this new species should be considered as “Least Concern”."

Long-term declines of native trees in an oceanic island's tropical forests invaded by alien plants / Vincent Florens in Applied Vegetation Science, vol. 20, n°1 (Année 2017)

Public [article]  inApplied Vegetation Science > vol. 20, n°1 (Année 2017) . - pp. 94-105 Titre : Long-term declines of native trees in an oceanic island's tropical forests invaded by alien plants Type de document : texte imprimé Auteurs : Vincent Florens, Auteur ; Claudia Baider, Auteur ; Nooshruth Seegoolam, Auteur ; Zeyn Zmanay, Auteur ; Dominique Strasberg, Auteur Année de publication : 2017 Article en page(s) : pp. 94-105 Langues : Anglais (eng) Résumé : "An unabated replacement of native by alien trees over the longer term is occurring in protected areas of the lowland wet forests of the BRGNP and presumably in other similarly invaded areas. Our work stresses the importance of long‐term monitoring in elucidating impacts of invasive alien plants at the community level, particularly when dealing with slow‐growing and long‐lived species. Plausible mechanisms bringing about the observed changes and that have been found at the same or similar sites, include reduced regeneration, growth, production of flowers and fruits and increased mortality of native trees when these grow among invasive alien plants. The control of invasive alien plants, where they invade tropical forests, should be a central conservation objective even in better preserved and well protected areas."

A new record of Portulaca (Portulacaceae) to La Réunion Island, Portulaca. cf. pilosa L. : native or recently (re-)introduced? / Stéphane Augros in Botany letters, vol. 165, n°2 (Année 2018)

Type de document : texte imprimé Auteurs : Stéphane Augros, Auteur ; Dominique Hoareau, Auteur ; Claudia Baider, Auteur Année de publication : 2018 Article en page(s) : pp. 193-199 Langues : Anglais (eng) Mots-clés : Portulacaceae   Portulaca pilosa complex   Mascarene islands   species origin  La Réunion Island Résumé : "Two species of Portulaca were currently reported from La Réunion Island, the native P. oleracea and the introduced P. quadrifida. A third species was presumed but never confirmed, P. pilosa. We recently found a population of P. cf. pilosa in a restricted area in the southwestern part of La Réunion, exclusively growing on tiles of tuff, a very singular and restricted habitat that also shelters some native and rare species, but is largely surrounded by alien vegetation. Given the cosmopolitan distribution of P. pilosa in warm regions, we suggest that the species could be alien. However, based on the wide infrageneric taxonomic resolution problems of Portulaca, coupled with the species’ alleged past records for the Mascarene and its presumed rarity, we call for more in-depth studies to assess the true origin and ecological significance of the species."
