Titre : Pilularia minuta Durieu (Marsileaceae) discovered in south-eastern-Sicily: new insights on its ecology, distribution and conservation status Type de document : texte imprimé Auteurs : Pietro Minissale, Auteur ; José Antonio Molina, Auteur ; Saverio Sciandrello, Auteur Année de publication : 2017 Article en page(s) : pp. 197-208 Langues : Anglais (eng) Mots-clés : Semi-natural grassland Résumé : "Pilularia minuta Durieu (Marsileaceae) is a rare and endangered Mediterranean species of temporary ponds. It occurs in different countries all around the Mediterranean Basin with a scattered distribution. In Italy; this species is known for Sardinia; Apulia and recently for western Sicily. During a field investigation; the species was found in the Hyblaean Plateau (south-eastern Sicily). The aim of this work is to analyze the ecological features and conservation status of P. minuta populations occurring in Sicily. The floristic composition of Pilularia minuta plant communities were determined using the standard relevé method. Three spatially differentiated belts with specific floristic compositions emerged from the numerical analysis (UPGMA method; Euclidean distance coefficient) and from canonical correspondence analysis (CCA); mainly correlated to the water level. Our results showed that temporary ponds mainly host amphibian vegetation belonging to the phytosociological class Isoëto-Nanojuncetea; which includes pioneering annual plant communities growing on periodically flooded soils. Most species belong to the Mediterranean element; with therophytes as the dominant life form. The floristic richness and diversity index of these plant communities increased from the inner belt towards the upper belt. Finally; a synthesis of all known localities of Pilularia minuta from the Mediterranean area is given; together with a new assessment of the risk status for Sicily and Italy."

Titre : Morpho-environmental characterization of the genus Dianthus L. in the Iberian Peninsula: environmental trends for D. pungens group under climate change scenarios Type de document : texte imprimé Auteurs : João Rocha, Auteur ; Paulo Almeida, Auteur ; Isabel Garcia-Cabral, Auteur ; Maxim Jaffe, Auteur ; Rubén Ramïrez-Rodrïguez, Auteur ; Francisco Amich, Auteur ; Antonio L. Crespí, Auteur Année de publication : 2017 Article en page(s) : pp. 209-227 Langues : Anglais (eng) Mots-clés : biogéographie holo-pleistocene climate change modelling resilience Dianthus Spain Portugal Résumé : "Potential habitat characterizations for past (Late Glacial Maximum), present and future scenarios were calculated for Iberian species of D. pungens gr. (D. pungens subsp. pungens, D. pungens subsp. langeanus, D. pungens subsp. gredensis, D. pungens subsp. brachyanthus and D. pungens subsp. hispanicus). Results were discussed according to Allison’s interpretation of insurance theory, where diversity is contrasted with resilient behaviours. Resilience is here defined as the diversification of responses to assure that functionality. The discussion of results was also compared with the morphological characterization. Environmental results confirmed the morphological similarity between these taxa. An apparent geographic divergence was observed: D. pungens subsp. hispanicus and D. pungens subsp. pungens supported an eastern response, while D. pungens subsp. langeanus and D. pungens subsp. gredensis supported a western response. The intermediate response for those extremes was supported by D. pungens subsp. brachyanthus. Based on these results, resilience in this genetic pool is concentrated on D. pungens subsp. gredensis and D. pungens subsp. hispanicus, while D. pungens subsp. langeanus, D. pungens subsp. brachyanthus and D. pungens subsp. pungens showed their resilience strategies to guarantee responses along the eastern, northern and western mountain systems for current environmental conditions only."
