Titre : Distribution, morphology and habitats of Elatine triandra (Elatinaceae) in Europe, with particular reference to the central part of the continent Type de document : texte imprimé Auteurs : Agnieska Popiela, Auteur ; Andrzej Lysko, Auteur ; Attila Molnar, Auteur ; Zygmunt Kacki, Auteur ; Balázs Andras Lukacs, Auteur Année de publication : 2015 Article en page(s) : pp. 324-337 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Elatine triandra
[Thèmes] PhytogéographieMots-clés : chorologie végétation morphologie cartographie phénologie Résumé : "Elatine triandra Schkuhr is the most variable and widespread species within the genus Elatine L.; it has been recorded in all continents, except Antarctica, but it is mainly located in Europe. The study is based on an extensive data set of European literature, herbaria and web data that covers the period 1828–2012. The range of the species in Europe is disjunctive, covering the southern and western parts of the Central European Plain and the southern part of the Fennoscandian Shield. At a smaller scale, the species can also be found along some river valleys. In Central Europe many localities, particularly isolated ones in the northern part of the range, are now only historical. From the data set we determined that E. triandra may be best observed between May and October. We found that species records show a near-significant shift since 1828. Depending on the environmental conditions, individuals of the taxon develop as one of two morphs: terrestrial or aquatic. The aquatic morph is characterized by stems, internodes, lamina and petiole that are twice as long as those of the terrestrial form. Elatine triandra seeds show consistent characteristics, both in terms of morphs and populations. Our studies show that the best diagnostic features, in addition to the construction of flowers, are the size, shape and surface structure of seeds. In Central Europe, E. triandra occurs exclusively in communities classified as Isoëto-Nano-Juncetea."

[Thèmes] LichensRésumé : "Very little is known of the earlier lichen flora of the Padanian Plain, the most heavily anthropized and industrialized part of Italy, which is currently extremely poor. Terricolous lichens in particular are the most sensitive to threats, and have almost totally disappeared from the western Padanian Plain. This paper reports new findings of 20 terricolous lichen species, several of which are rare or poorly known in Italy or are of some phytogeographical interest because they are found at lower altitudes than their usual distribution (i.e. Cladonia coccifera, Cladonia uncialis). In addition, Cladonia humilis is new for Lombardy and two other species, Cladonia portentosa and Stereocaulon condensatum, are reported for the second time in the same region. The significance of these species is discussed with regard to their historical records from the same area and their current altitudinal distribution; they were probably much more widespread in the past, but the decline and disappearance of their habitats in lowland areas have been followed by their own disappearance in many localities. A modification of the rarity status of some of these species in the considered phytoclimatic belts, based on the new records, is proposed."

Titre : Germination requirements of nine European Aegilops species in relation to constant and alternating temperatures Type de document : texte imprimé Auteurs : Filippo Guzzon, Auteur ; Jonas V. Müller, Auteur ; Thomas Abeli, Auteur ; Paolo Cauzzi, Auteur ; Nicola M. G. Ardenghi, Auteur ; Alma Balestrazzi, Auteur ; Graziano Rossi, Auteur ; Simone Orsenigo, Auteur Année de publication : 2015 Article en page(s) : pp. 349-354 Langues : Anglais (eng) Catégories : [Espèces (in biblio)] Aegilops Mots-clés : plante sauvage écologie germination reproduction graine culture Résumé : "The genus Aegilops represents the secondary gene pool of wheat. A better understanding of the germination behaviour of Aegilops species is important to improve their use in breeding programmes and strengthen their in situ/ex situ conservation. In this study, we investigated the germination behaviour of nine Aegilops species, five of them not yet investigated, under two alternating and two constant temperatures. Seed germination was higher than 60% in all temperature treatments and species. Alternating temperatures promoted higher germination rates in all the species and significantly enhanced seed germination in three species (Aegilops biuncialis, Aegilops geniculata and Aegilops neglecta), in comparison with constant temperatures. One of the rarest and least productive species in the genus (Aegilops uniaristata) displayed the highest germination. This study suggests that different (seed) regeneration strategies/niches occur across Aegilops species."

This has caused the degradation, or even loss, of several habitats, especially wetlands, which frequently preserve rare biodiversity, even though they are subjected to intense human presence. Human activities can be of value, but can also cause problems in species preservation. The protected area “Ansa e Valli del Mincio” (northern Italy) is an outstanding case study in this respect: it is located in a densely urbanized context, but has great value from a conservation standpoint. This paper presents the results of 10 years of monitoring (2003–2012) of the spatial distribution of two native species (and Nymphaea alba) and the invasive Nelumbo nucifera. Data collected by volunteers from the protected area were processed in GIS and analysed using a number of configurational landscape metrics. Nymphaea alba and N. nucifera became more widespread; T. natans underwent a serious decline, mostly due to the interference of N. nucifera. An oscillating trend of this species is visible until 2008, followed by substantial stability. Furthermore, the potential area of each species was calculated. On the whole, citizen science is a valuable tool to enhance biodiversity knowledge and safeguarding, especially in wetlands that are used for tourism and surrounded by residential areas. As in other contexts, the volunteer contribution was particularly helpful in data collection on a local scale, over a considerable time span."
