Steudel Résumé : Cryptic invasions are a largely unrecognized type of biological invasion that lead to underestimation of the total numbers and impacts of invaders because of the difficulty in detecting them. The distribution and abundance of Phragmites australis in North America has increased dramatically over the past 150 years. This research tests the hypothesis that a non-native strain of Phragmites is responsible for the observed spread. Two noncoding chloroplast DNA regions were sequenced for samples collected worldwide, throughout the range of Phragmites. Modern North American populations were compared with historical ones from herbarium collections. Results indicate that an introduction has occurred, and the introduced type has displaced native types as well as expanded to regions previously not known to have Phragmites. Native types apparently have disappeared from New England and, while still present, may be threatened in other parts of North America.

Origin of the invasive Arundo donax (Poaceae) : a trans-Asian expedition in herbaria / Laurent Hardion in Annals of Botany, 114 (2014) 

Public Citation [article]  inAnnals of Botany > 114 (2014) . - 1-8 Titre : Origin of the invasive Arundo donax (Poaceae) : a trans-Asian expedition in herbaria Type de document : Électronique Auteurs : Laurent Hardion ; Régine Verlaque ; Kristin Saltonstall ; Agathe Leriche ; Bruno Vila Année de publication : 2014 Article en page(s) : 1-8 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Domestication des plantes [CBNPMP-Thématique] Phylogénie (liens existant entre espèces apparentées) [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Arundo donax L., 1753 Résumé : Background and Aims : The hypothesis of an ancient introduction, i.e. archaeophyte origin, is one of the most challenging questions in phylogeography. Arundo donax (Poaceae) is currently considered to be one of the worst invasive species globally, but it has also been widely utilzed by man across Eurasia for millennia. Despite a lack of phylogenetic data, recent literature has often speculated on its introduction to the Mediterranean region. Methods : This study tests the hypothesis of its ancient introduction from Asia to the Mediterranean by using plastid DNA sequencing and morphometric analysis on 127 herbarium specimens collected across sub-tropical Eurasia. In addition, a bioclimatic species distribution model calibrated on 1221 Mediterranean localities was used to identify similar ecological niches in Asia. Key Results : Despite analysis of several plastid DNA hypervariable sites and the identification of 13 haplotypes, A. donax was represented by a single haplotype from the Mediterranean to the Middle East. This haplotype is shared with invasive samples worldwide, and its nearest phylogenetic relatives are located in the Middle East. Morphometric data characterized this invasive clone by a robust morphotype distinguishable from all other Asian samples. The ecological niche modelling designated the southern Caspian Sea, southern Iran and the Indus Valley as the most suitable regions of origin in Asia for the invasive clone of A. donax. Conclusions : Using an integrative approach, an ancient dispersion of this robust, polyploid and non-fruiting clone is hypothesized from the Middle East to the west, leading to its invasion throughout the Mediterranean Basin.
