Une nouvelle localité, la plus haute en Alsace, d’une mousse "thermophile"1: Rhynchostegium rotundifolium

Rhynchostegium rotundifolium (Scop. ex Brid.) Schimp. a été récolté (herbier AU N° 8878) le 21/5/2011 à La Rolle, Forêt Domaniale de Guebwiller, parcelle 64, Lautenbachzell, Haut-Rhin, à une altitude de 825 m (Coord. Lambert 2 étendu : x = 954 632; y = 2 335 811). Le petit tapis formé par cette pleurocarpe à ramifications entrelacées s’étendait sur 30 cm² sur un bloc de grauwacke affleurant le sol à l’ombre d’une mégaphorbiée nitratophile (Chenopodium bonus-henricus L., Rumex obtusifolius L., Urtica dioica L. etc.)

<I>Dicranum viride</I> (Sull. <I>et</I> Lesq.) Lindb. en el Pirineo español. Hábitat, población y estado de conservación

Dicranum viride (Sull. et Lesq.) Lindb. has been found on the southern versant of the Pyrenees (Irati Forest, Navarra). This is the only Iberian locality of this threatened species. In this area the species was only known from Pyrénées-Atlantiques and Haute-Garonne in the French versant. Its habitat on the new locality has been studied, comparing to other places in France and Germany where the species is known to occur. In Irati, D. viride prefers the north-facing upper base - lower trunk parts of beech trees, median to large in diameter, and it is usually accompanied by Pterigynandrum filiforme and Hypnum cupressiforme var. cupressiforme. The species is proposed to be included in the Red List of Iberian Bryophytes as "Vulnerable" (VU).Dicranum viride (Sull. et Lesq.) Lindb. a été trouvé sur le versant méridional des Pyrénées (forêt d\u27Irati, Navarre). Il s\u27agit de l\u27unique localité ibérique pour cette espèce menacée. Dans le versant français, l\u27espèce était connue des Pyrénées-Atlantiques et de la Haute-Garonne. Une étude de l\u27habitat de l\u27espèce a été réalisée dans la nouvelle localité, la comparant avec celle d\u27autres stations en France et en Allemagne. A Irati, D. viride préfère les parties supérieures des bases - inférieures des troncs de hêtre de diamètre moyen et grand, orientées au Nord. Les mousses Pterigynandrum filiforme et Hypnum cupressiforme var. cupressiforme en sont les plus fidèles compagnes. On propose d\u27inclure l\u27espèce dans la Liste Rouge des Bryophytes Ibériques dans la catégorie de « Vulnérable » (VU).</p

Bruchia vogesiaca SCHWÄGR. en France - Répartition, écologie et conservation d’une espèce anthropophile

Bruchia vogesiaca Schwägr. est une mousse présente dans 12 départements en France bien que non revue récemment dans 4 d'entre eux. Une douzaine de nouvelles localités du Massif central et des Vosges sont présentées dans la présente contribution. L'écologie de l'espèce est examinée sous l'angle des biotopes d'accueil. La stratégie du cortège d'espèces liées à Bruchia vogesiaca permet de mieux cerner la dynamique de l'espèce. Des préconisations de mesures de gestion sont énoncées sur ces nouvelles bases.Bruchia vogesiaca Schwägr. is a moss recorded in 12 departments in France from which 4 have not been confirmed recently. A dozen of new localities in Massif central and Vosges are provided in the present account. Habitats of Bruchia vogesiaca are reviewed. Analysing the strategy of Bruchia vogesiaca and the associated species allows a better understanding of the dynamics. Conservation strategies are provided on this revisited basis

A miniature world in decline: European Red List of Mosses, Liverworts and Hornworts

This publication has been prepared by IUCN (International Union for Conservation of Nature) as a deliverable of the LIFE European Red Lists project (LIFE14 PRE BE 001). A miniature world in decline: The European Red List of Mosses, Liverworts and Hornworts is, therefore, a part of a series of publications released since 2015, when the project began, that also include: • European Red List of Lycopods and Ferns, 2017 • European Red List of Saproxylic Beetles, 2018 • European Red list of Terrestrial Molluscs: slugs, snails, and semi-slugs, 2019 • European Red list of Trees, 2019 • European Red list of Selected Endemic Shrubs, 2019 Based on other European Red List assessments, 59% of freshwater molluscs, 40% of freshwater fishes, 28% of grasshoppers, crickets and bush-crickets, 23% of amphibians, 20% of reptiles, 20% of ferns and lycopods, 17% of mammals, 16% of dragonflies, 13% of birds, 9% of butterflies and bees, 8% of aquatic plants and 2% of medicinal plants are threatened at the European level (Allen et al., 2014; IUCN, 2015; Hochkirch et al., 2016; García Criado et al., 2017). Additional European Red Lists assessing a selection of species showed that 22% of terrestrial molluscs, 16% of crop wild relatives and 18% of saproxylic beetles are also threatened (Cuttelod et al., 2011; Bilz et al., 2011; Cálix et al., 2018). The findings of this work suggest that 23% of bryophytes are threatened species in Europe, representing the fifth most threatened group of plants assessed so far
