Country-specific correlations across Europe between modelled atmospheric cadmium and lead deposition and concentrations in mosses
2012
Previous analyses at the European scale have shown that cadmium and lead concentrations in mosses are primarily determined by the total deposition of these metals. Further analyses in the current study show that Spearman rank correlations between the concentration in mosses and the deposition modelled by the European Monitoring and Evaluation Programme (EMEP) are country and metal-specific. Significant positive correlations were found for about two thirds or more of the participating countries in 1990, 1995, 2000 and 2005 (except for Cd in 1990). Correlations were often not significant and sometimes negative in countries where mosses were only sampled in a relatively small number of EMEP gr…
Life forms, life strategies and ecological indices of bryophytes for bioindication in wood areas: a case of study in the "Bosco della Ficuzza, Rocca …
2015
Life forms, life strategies and ecological indices of bryophytes which live in evergreen and deciduous Quercus woods as well as in a Pinus halepensis artificial system within the "Bosco della Ficuzza, Rocca Busambra, Bosco del Cappelliere e Gorgo del Drago" Oriented Nature Reserve are analysed and compared. The study highlights that in the same local climatic conditions the Quercus and Pinus trees select different bio-ecological types in the bryophyte communities. They appear to be especially useful to detect physionomic-structural differences in the woods, integrating the information provided by the ecological indices
Water Extract of Cryphaea heteromalla (Hedw.) D. Mohr Bryophyte as a Natural Powerful Source of Biologically Active Compounds
2019
Bryophytes comprise of the mosses, liverworts, and hornworts. Cryphaea heteromalla, (Hedw.) D. Mohr, is a non-vascular lower plant belonging to mosses group. To the date, the most chemically characterized species belong to the liverworts, while only 3.2% and 8.8% of the species belonging to the mosses and hornworts, respectively, have been investigated. In this work, we present Folin–Ciocalteu and oxygen radical absorbance capacity (ORAC) data related to crude extracts of C. heteromalla obtained by three di erent extraction solvents: pure water (WT), methanol:water (80:20 v/v) (MET), and ethanol:water (80:20 v/v) (ETH). The water extract proved to be the best solvent showing the highest con…

Pseudoamblystegium subtile (Hedw.) Vanderp. & Hedenäs. CONTRIBUTORS: R. Gabriel, M. Kubová, C. Sérgio and I. Soares Albergaria. PORTUGAL, AZORES: Terceira Island, Angra do Heroísmo, municipal garden ‘Jardim Duque da Terceira’, 38° 39′ 24.0′′N, 27°13′ 05.99′′W, 31 m a.s.l, on the base of a shrub, in acidic conditions, 7 April 2017, leg. Michaela Kubová s.n. (AZU). A new understanding of the pleurocarpous moss species Pseudoamblystegium subtile was proposed by Vanderpoorten and Hedenäs (2009). The new genus is separated from the other Amblystegiaceae primarily due to its phylogenetic consistency and is characterised by the possession of leaves with a very short nerve, and erect capsules (Vand…

Les mousses des champs : quels effets sur les cultures ?
2021
Le développement de bryophytes dans les systèmes cultivés,notamment ceux limitant très fortement le travail du sol, pose la question de leur impact sur les cultures et la écessité ou non de les contrôler.CONTEXTE - Les bryophytes sont largement présentes dans les milieux occupés parl’homme. Comme pour beaucoup de communautés se développant dans de tels environnements (espèces adventices, insectes, etc.),leur présence peut être perçue positivementou négativement en fonction de la gêne, fondéeou infondée, qu’elle provoque.ÉTUDE - Cet article a pour objectif de mieuxconnaître cette composante de l’agroécosystème et de comprendre comment elle fonctionne et quelles sont ses interactions potentie…
Bryophyte diversity in the gypsum outcrops of Sicily (Italy)
2020
Abstract: A study on the bryophyte diversity of 12 Sicilian gypsum outcrops, falling in 4 Nature Reserves and 5 Special Areas of Conservation (SAC), is presented in order to increase knowledge about this peculiar flora for which conservation efforts need to be addressed. The bryoflora consists of a total of 85 taxa, 8 liverworts and 77 mosses, most of them belonging to the Pottiaceae family and characterized by xero-morphological adaptations. The bio-ecological analysis has emphasized the prevalence of xerophytic and basiphytic species with life form turf and life strategy colonist. Regarding the gypsicolous character, only one species, Tortula revolvens, behaves as a strict gypso- phyte, a…
