Tipping Année de publication : 2016 Article en page(s) : 299-305 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Azolla Résumé : Biological control of Azolla filiculoides in South Africa with the Azolla specialist Stenopelmus rufinasus has been highly successful. However, field surveys showed that the agent utilized another Azolla species, thought to be the native Azolla pinnata subsp. africana, which contradicted host specificity trials. It is notoriously difficult to determine Azolla species based on morphology so genetic analyses were required to confirm the identity of the Azolla used by the agent. Extensive sampling was conducted and samples were sequenced at the trnL-trnF and trnG-trnR chloroplastic regions and the nuclear ITS1 region. Current literature reported A. filiculoides as the only Section Azolla species in southern Africa but 24 samples were identified as Azolla cristata, an introduced species within Section Azolla thatwas not used during host specificity trials. A. pinnata subsp. africanawas only located at one site in southern Africa, while the alien A. pinnata subsp. asiatica was located at three.Whatwas thought to be A. pinnata subsp. africana was in fact A. cristata, a closer relative of A. filiculoides and a suitable host according to specificity trials. This study confirms that S. rufinasus is a proficient Azolla taxonomist but also supports the use of molecular techniques for resolving taxonomic conundrums.

Titre : Monographs on invasive plants in Europe N° 2 : Eichhornia crassipes (Mart.) Solms Type de document : Imprimé Auteurs : Julie A Coetzee ; Martin P. Hill ; Trinidad Ruiz Téllez ; Uwe Starfinger ; Sarah Brunel Année de publication : 2017 Article en page(s) : 303-326 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Eichhornia crassipes (Mart.) Solms Résumé : Eichhornia crassipes is notorious as the world’s worst aquatic weed, and here we present all aspects of its biology, ecology and invasion behaviour within the framework of the new series of Botany Letters on Monographs on invasive plants in Europe. Native to the Amazon in South America, the plant has been spread around the world since the late 1800s through the ornamental plant trade due to its attractive lilac flowers, and is established on every continent except Antarctica. Its distribution is limited in Europe to the warmer southern regions by cold winter temperatures, but it has extensive ecological and socio-economic impacts where it invades. Its reproductive behaviour, characterised by rapid vegetative spread and high seed production, as well as its wide physiological tolerance, allows it to proliferate rapidly and persist in a wide range of environments. It has recently been regulated by the EU, under Regulation No. 1143/2014, which states that E. crassipes shall not be brought into the territory of the Union, kept, bred or transported to, from or within the Union. However, in the absence of effective control measures, such as herbicidal and biological control, it will continue to be a significant threat to European waterways, particularly in eutrophic waters, and under future climate change scenarios.

Titre : Naturalised Hakea. What species are we actually talking about in Europe? Type de document : Imprimé Auteurs : Johannes Leonardus Cornelis Hendrikus van Valkenburg (1964) ; Jesse Beyer ; Philippe Champion ; Julie A Coetzee ; Katia Diadema (1980-) ; Suzaan Kritzinger-Klopper ; Elizabete Marchante ; Laurens F. Piet ; David Mark Richardson (1958-) ; Ines Schönberger Année de publication : 2024 Langues : Anglais (eng) Catégories : [CBNPMP-Thématique] Plantes subspontanées, naturalisées, envahissantes Mots-clés : Hakea sericea Schrad. & J.C.Wendl Hakea Résumé : Hakea sericea Schrad. & J.C.Wendl. (Proteaceae) is a shrub or small tree native to south-eastern Australia. The species has been introduced to other countries; it has naturalised and become invasive in France, New Zealand, Portugal, and South Africa. During the review process of the Pest Risk Analysis for the European and Mediterranean Plant Protection Organization (EPPO) on Hakea sericea in 2017, the actual identity of the plant causing major negative biodiversity impact in Portugal was questioned. Flowering material from Portugal and additional collec-tions from South Africa and New Zealand were collected in order to clarify the taxonomical status. To make the survey on the proper identity of the Hakea plants invasive in Portugal more concise, all Hakea species encountered in Portugal, France, South Africa and New Zealand were included. For morphological distinction of the species the length of the pistil and fruit characters were used. For molecular analysis Illumina sequencing in combination with de novo assembly and extraction of loci was used. Results show that invasive populations of Hakea in Portugal belong to H. decurrens R.Br a species that, although very similar and some-times considered synonymous with H. sericea, can be distinguished both morphologically and on the basis of cpDNA. Both species occur in France and in New Zealand, while only H. sericea occurs in South Africa. Both species are invasive and seem to have similar impacts on biodiversity in invaded ranges. The morphologically similar species H. gibbosa (J.White) Cav. occurs in both New Zealand and South Africa. By adopting the H. sericea sensu lato concept for inclusion of the species on the List of Union Concern pursuant of Regulation (EU) No 1143/ 2014, a potential legislative controversy can be prevented.
