Two new liverworts for Europe in Macaronesia : Odontoschisma prostratum (Sw.) Trevis. on the Azores and Jungermannia callithrix Lindenb. & Gottsche on the Azores and Madeira

Odontoschisma prostratum (Sw.) Trevis. and Jungermannia callithrix Lindenb. et Gottsche, two liverworts mainly distributed in the Neotropics, are reported at hand of many collections from Macaronesia. O. prostratum occurs on 8 of the 9 Azorean islands, growing on all type of substrates, even epiphyllous, but rarely in bogs. J. callithrix is known from 8 Azorean islands and from Madeira, growing epigeic. The phytogeographical interest of the occurrence on the Azores of some 39 liverworts (among 147) belonging to the neotropical and/or paleotropical elements is discussed. Most of the neotropical species may have been easily transported to the Azores by the frequent depressions (or occasionally storms) moving rapidly at relatively low altitude (3,000 m) from the North or Central American eastern coasts or from the Caribbean islands and Bermuda to Western Europe in a few days. Only a few of these species could have been be introduced by human activities, mainly along the coast

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
