Keys for the Determination of Families of Pleurocarpous Mosses of Africa
Keys for the determination of families of pleurocarpous mosses of Africa E. Petit Extracted from: Cléfs pour la determination des familles et des genres des mousses pleurocarpes (Musci) d'AfriqueBull. Jard. Bot. Nat. Belg. 48: 135-181 (1978) Translated by M.J.Wigginton, 36 Big Green, Warmington, Peterborough, PE and C.R. Stevenson, 111 Wootton Road, King's Lynn, Norfolk, PE The identification of tropical African mosses is fraught with difficulty, not least because of the sparseness of recent taxonomic literature. Even the determination of specimens to family or genus can be problematical. The paper by Petit (1978) is a valiant attempt to provide workable keys (and short descriptions) to all the families and genera of African pleurocarpous mosses, and remains the only such comprehensive treatment. Whilst the shortcomings of any such keys apply, the keys have nonetheless proved to be of assistance in placing specimens in taxonomic groups. However, for the non-French reader, the use of the keys can be a tedious business, necessitating frequent recourse to dictionaries and grammars. Members of the BBS have made collections in a number of tropical African countries in recent years, including on the BBS expedition to Malawi and privately to Madagascar, Tanzania and Zaire. This provided the impetus for making a translation of Petit's keys. Neither of us is an expert linguist, and doubtless in places, some of the subtleties of the language have escaped us. A rather free translation has sometimes proved necessary in order to give the sense of the text. Magill's Glossarium Polyglottum Bryologicae has been valuable in assisting with technical terms. -

About the Book the Format Acknowledgments
About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization. -
Desiccation Tolerance in the Antarctic Moss Sanionia Uncinata Marisol Pizarro, Rodrigo A
Pizarro et al. Biol Res (2019) 52:46 https://doi.org/10.1186/s40659-019-0251-6 Biological Research RESEARCH ARTICLE Open Access Desiccation tolerance in the Antarctic moss Sanionia uncinata Marisol Pizarro, Rodrigo A. Contreras, Hans Köhler and Gustavo E. Zúñiga* Abstract Background: One of the most extreme environments on our planet is the Maritime Antarctic territory, due to its low- water availability, which restricts the development of plants. Sanionia uncinata Hedw. (Amblystegiaceae), the main colonizer of the Maritime Antarctic, has efective mechanisms to tolerate this environment. It has been described that the tolerance to desiccation is mediated by the hormone abscisic acid (ABA), antioxidants systems, accumulation of compatible solutes and proteins of the late embryogenesis abundant (LEA). However, to date, these mechanisms have not been described in S. uncinata. Therefore, in this work, we postulate that the tolerance to desiccation in the Antarctic moss S. uncinata is mediated by the accumulation of ABA, the osmolytes proline and glycine betaine, and dehydrins (an LEA class 11 proteins). To demonstrate our hypothesis, S. uncinata was subjected to desiccation for 24 h (loss in 95% of water content), and the efects on its physiological, photosynthetic, antioxidant and biochemical parameters were determined. Results: Our results showed an accumulation of ABA in response to water loss, and the activation of protective responses that involves an increment in levels of proline and glycine betaine, an increment in the activity of antioxi- dant enzymes such as SOD, CAT, APX and POD, and the accumulation of dehydrins proteins. Conclusion: The results showed, suggest that S. uncinata is a desiccation-tolerant moss, property mediated by high cellular plasticity regulated by ABA. -

A Molecular Phylogeny of Hypnales (Bryophyta) Inferred from ITS2 Sequence-Structure Data Benjamin Merget, Matthias Wolf*
Merget and Wolf BMC Research Notes 2010, 3:320 http://www.biomedcentral.com/1756-0500/3/320 SHORT REPORT Open Access A molecular phylogeny of Hypnales (Bryophyta) inferred from ITS2 sequence-structure data Benjamin Merget, Matthias Wolf* Abstract Background: Hypnales comprise over 50% of all pleurocarpous mosses. They provide a young radiation complicating phylogenetic analyses. To resolve the hypnalean phylogeny, it is necessary to use a phylogenetic marker providing highly variable features to resolve species on the one hand and conserved features enabling a backbone analysis on the other. Therefore we used highly variable internal transcribed spacer 2 (ITS2) sequences and conserved secondary structures, as deposited with the ITS2 Database, simultaneously. Findings: We built an accurate and in parts robustly resolved large scale phylogeny for 1,634 currently available hypnalean ITS2 sequence-structure pairs. Conclusions: Profile Neighbor-Joining revealed a possible hypnalean backbone, indicating that most of the hypnalean taxa classified as different moss families are polyphyletic assemblages awaiting taxonomic changes.

Wittmann Sir, said he. there is nothing too little for so little a creature as man. It is by studying little things tha t we attain the great knowledge of having as little misery and as much happiness as possible. Samuel Johnson to James Boswell, recorded in Boswell s Journal, 16 July 1763 PREFACE In 1934, when I was still in high school, I entered a competition at the American Museum of Natural History, I won a prize of $25.00 for building a terrarium containing, among salamanders and tree frogs, some mosses and lichens. W ith the money I was able to purchase four books: The New York Walk Book; Out Of D oors, by William B . Mann, a well-known bio logy teacher; Ferns of the New York City Region, by John Kunkel Small, and Mosses With a Hand Lens, by Abel Joel Grout. Mr. Grout was a high school teacher on Staten Island, and an associate of the New York Botanical Garden. He spent a lifetime becoming a specialist on mosses, and eventually produced a classic three-volume work entitled Moss Flora of North America, written with the aid o f as many specialists as he could muster. Mosses with a Hand Lens was written from the standpoint that Grout felt that, with proper attention and guidance, a person could learn to recognize most of the common mosses of the New York City Region with the use of only a hand lens and his book. -

Eight species of Hygrohypnum occur in the Iberian Peninsula: Hygrohypnum cochlearifolium , H. duriusculum , H. eugyrium , H. luridum , H. molle, H. ochraceum , H. smithii and H. styria- cum . Of these, H. eugyrium and H. cochlearifolium are considered to be extinct in the Iberian Peninsula. Hygrohypnum alpestre and H. polare are definitively excluded from the Iberian bryophyte flora, since its occurrence at present or in the past could not be confirmed. Only the occurrence of Hygrohypnum ochraceum has been confirmed for Portugal. Keys, descriptions, illustrations, SEM photographs and distribution maps of the species of Hygrohypnum in the Iberian Peninsula are provided. Hygrohypnum /Amblystegiaceae / Iberian Peninsula / flora / taxonomy / distribution INTRODUCTION Taxonomic history of Hygrohypnum The generic name Hygrohypnum was introduced by Lindberg (1872) to replace the illegitimate name Limnobium used by Schimper (1853), who was the first to treat the genus as separate from the broadly conceived Hypnum Hedw. -

Habitat affinities of the red-listed and EU Habitat Directive moss species Hamatocaulis vernicosus and the more widely distributed allied species Scorpidium cossonii and Warnstorfia exannulata were analysed. Ecological preferences of these fen mosses, with respect to water pH, water conduc- tivity, Ellenberg’s moisture and nutrient indicator values, were compared in three different Euro- pean locations (Bohemian Massif, the West Carpathians and Bulgaria) using logistic regressions fitted by means of Huisman-Olff-Fresco models. Inter-specific co-occurrences of the species were also investigated.
