Titre : Monographs on Invasive Plants in Europe n° 2 : Eichhornia crassipes (Mart.) Solms Type de document : texte imprimé Auteurs : Julie Coetzee, Auteur ; Martin P. Hill, Auteur ; Trinidad Ruiz Téllez, Auteur ; Uwe Starfinger, Auteur ; Sarah Brunel, Auteur Année de publication : 2017 Article en page(s) : pp. 303-326 Langues : Anglais (eng) Mots-clés : Jacinthe d'eau invasion gestion plante invasive législation 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 : Notes on the distribution, ecology and conservation status of two very rare sedges (Carex, Cyperaceae) rediscovered in Sicily (Italy) Type de document : texte imprimé Auteurs : Lorenzo Gianguzzi, Auteur ; Agostino D'Amico, Auteur ; Angelo Troia, Auteur Année de publication : 2017 Article en page(s) : pp. 339-349 Langues : Anglais (eng) Mots-clés : Carex × boenninghausiana Carex grioletii chorologie endangered species flora IUCN assessment taxonomie Résumé : "New data on the geographical distribution and ecology of two rare taxa of Carex collected in the area of the Nebrodi Mountains (Sicily) are provided; the Sicilian populations of both taxa are at the border of their respective ranges, and their regional distribution is still poorly known. The new population of Carex × boenninghausiana reported here confirms the presence of this hybrid in Sicily, but at the same time it represents the only known population currently occurring in Italy; in fact, the other – so far only – known Italian population is considered extinct. The second report concerns Carex grioletii, recently considered doubtful for the Sicilian flora, whose new population here reported is the only confirmed and currently present population in the island; the assessment of extinction risk and conservation status, carried out at regional (Sicilian) level according to the IUCN criteria for the latter taxon, showed that it is Critically Endangered (CR)."

Titre : Effects of local abundance on pollination and reproduction in Delphinium fissum subsp. sordidum (Ranunculaceae) Type de document : texte imprimé Auteurs : Rubén Ramírez-Rodríguez, Auteur ; Francisco Amich, Auteur Année de publication : 2017 Article en page(s) : pp. 371-383 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Ranunculaceae Mots-clés : Delphinieae graine pollinisation conservation Résumé : "Delphinium fissum subsp. sordidum (Ranunculaceae) is an endangered, xenogamous, self-compatible hemicryptophyte endemic of the central-western Iberian Peninsula, with a disjunct distribution in the Sierra Mágina (Spain: Jaén Province). We studied the effects of local abundance, in terms of plot size (number of individuals) and plot purity (relative abundance), assessing the activity of pollinators (frequency of visits and behaviour of visitors), quantity and quality of pollinator services and seed set in two populations. Flowers of D. fissum subsp. sordidum were visited by Hymenoptera (88.8%), Lepidoptera (10.3%) and Diptera (0.9%). The most frequent pollinator was Bombus terrestris (72.6% of total visits). Differences in relative frequency of visits to plants were observed between populations. Plots with high numbers of individuals attracted more pollinators. The same pattern was observed for stigmatic pollen loads and seed set; 99.46% of pollen grains deposited on the stigmas were conspecific, and the main competitor was Ferula communis. The effects of purity were assessed by comparing pure plots with a mixed plot that included plants that coincide with the flowering stage of D. fissum subsp. sordidum and exert an effect of interspecific competition. These results may be useful for developing conservation measures, especially in the small population of Aldeadávila."

Titre : Assessing the effects of mowing machinery on seed dispersal pattern: a test of two methods of seed tracking Type de document : texte imprimé Auteurs : Clémence Chaudron, Auteur ; Francis Isselin-Nondedeu, Auteur Année de publication : 2017 Article en page(s) : pp. 413-423 Langues : Anglais (eng) Mots-clés : dispersion des graines mower road verges field margins seed shadows seed traits Résumé : "Seed dispersal is a key process that humans can influence in various ways. However, this type of interaction is less studied than dispersal by other animals. In addition, tracking seeds to determine dispersal pattern is a complicated task. We explored the effects of mowing machinery on seed dispersal in roadsides by testing two methods, (i) by marking fruits and diaspore of plants within the standing vegetation (ii) by making fake plants containing estimated quantities of marked seeds. We measured the pattern of dispersal by considering each seed and the centre of seed shadows of each species calculated by two means (i.e. the centroids and the gravity centres). We estimated the distance of dispersal from roadsides, and the deviation angle from the direction of the mowing. We then analysed the variation in dispersal patterns among species, seed mass and width/length ratio by using correlation tests. Seeds coloured within the standing vegetation were detected from 0.5 to 15.51 metres away from roadsides, with deviation angles from the mowing machinery ranging from –153.43° to 161.57°. With the other method we found a mean distance of dispersal ranging from 0.5 to 13.01 metres and deviation angle from –168.69° to 180°. We did not find strong variation in dispersal patterns among species and seed traits, but we demonstrated however that mowing machinery influenced both dispersal distance and deviation angles."

[Thèmes] Plante indicatriceMots-clés : écologie phytosociologie Directive Habitats-Faune-Flore Résumé : "The importance of heathlands as habitats for plants and thus for nature conservation is recognized by European Directive 92/43 (Habitats Directive). However, heathlands are threatened by habitat loss and quality degradation due to several drivers. Temperate Calluna vulgaris communities in the Po basin and in the Southern Alps (NW Italy) are disjunct from the core distribution area in Western Europe and occur at their climatic limits. This study aimed to analyze floristic patterns of heather communities in NW Italy in order to provide detailed recommendations for local conservation needs. Data on plant species composition (phytosociological relevés) and abiotic (environmental and geographical) factors were jointly analyzed using multivariate statistical analyses, to provide a quantitative and statistical interpretation of variation among heathland communities. We show that diversity in species composition was associated with variation in abiotic factors, and we sorted an initial list of typical species of the heathers habitat among indicator species. Several subtypes of heathlands were also recognized and related to habitats élémentaires, which require specific conservation measures to preserve their floristic diversity. Finally, we proposed a revised syntaxonomy of heathlands for NW Italy."
