The relationship between morphological traits and micronutrients and trace elements, however, has been much less studied. Additionally, in bryophytes, research devoted to investigating these relationships is still very scarce. Here, we analysed 80 samples from 29 aquatic and semi-aquatic (hygrophytic) moss species living in Mediterranean springs to investigate the relationship between moss nutrient concentrations and their micro- and macroscopic morphological traits and growth forms. We found that, across species, the elemental concentration of mosses was more tightly linked to macroscopic traits than to microscopic traits. Growth forms could also be successfully explained by Citation: Fernández-Martínez, M.; the concentration of elements in mosses.

Generally, plants pre- senting higher concentrations of N and P, and lower C:N and N:P ratios, tend to be fast growing and more productive; reproduce more, and more frequently; and require fewer defence mechanisms; while a more conservative lifestyle is shown by nutrient-limited plants [15,20–22]. Similar patterns have also been shown in bryophytes [23,24] suggesting that a link between the elemental composition of plants and their morphological and functional traits should occur throughout the plant kingdom. Recent publications focused on bryophyte functional traits have considerably in- creased our knowledge regarding the relationship between the environment and bryophyte functional traits [25–29]. In particular, some of these studies identified water chemistry (e.g., pH, dissolved nutrients, and heavy metals) as an important determinant of moss traits and growth forms [2,25,28]. Other studies, focused on how several traits are related to each other, made very relevant contributions in order to emulate the leaf economic spectrum described for vascular plants [23,24]. These studies provided very relevant information on how bryophyte morphological traits, and N and P concentrations are related to their photosynthesis and dark respiration rates, indicating similar patterns to those observed in vascular plants [22]. However, to the best of our knowledge, no efforts have been devoted to investigating whether the elemental composition of bryophytes is related to their micro- and macroscopic morphological traits and growth forms across a large number of species. To fill in this gap, we here analysed 80 samples from 29 aquatic and semi-aquatic (hygrophytic) moss species to investigate the relationship between gametophyte moss nutrient concentrations and their morphological traits. We hypothesised that the elemental composition of moss species will be a very good indicator of their morphological traits, similar to that which has been reported in vascular plants [15,17,22]. Additionally, we hypothesise that moss species presenting higher concentrations of N and P, and low C:N, C:P, and N:P stoichiometric ratios, related to more productive organisms, will present larger and wider leaves and will be lighter (i.e., less dense and less mass per area). Our results will help us to further understand how the elemental composition of organisms determine their functional traits and ecological strategies in bryophytes. 2. Methods 2.1. Data Collection and Analyses of Elemental Composition and Morphological Traits We used previously published data in which we analysed the elemental composition of moss samples [30,31] from a large collection used in a previous study [25] for which their morphological traits were already estimated, including 29 different hygrophytic moss species. From the total collection of 100 samples with morphological traits, 80 samples had enough mass to analyse their elemental composition. Those 80 samples were used to perform this study. Moss samples were collected from springs distributed across Catalonia (north-eastern Iberian Peninsula, Figure S1) following a large climate and hydrochemical gradient [32]. In the subset of springs used here, water pH ranged from 5.17 to 8.34 (median: 7.20) and water conductivity ranged from 24 to 2094 (median: 498) µS cm−1. A detailed analysis of the water chemical composition can be found in the online material from references [25,30,31]. All mosses collected were in direct contact with the water of the springs throughout the year, with only occasional interruptions in water flow during winter and summer (when water freezes or during intense drought events, respectively). Given that these springs were draining water from aquifers, their water chemical composition was very stable in time. The climate of the area of study is Mediterranean, ranging from humid to sub-humid, and with large differences in mean annual temperature and precipitation (from 4.2 to 15.7 ◦C, and from 567.4 to 1202.4 mm y−1, respectively) [25,33]. Before the moss elemental analyses, we submerged all samples in a solution of acetic acid at pH 2.7 for 15 min in order to remove incrustations of CaCO3. A few samples required up to an hour to remove all CaCO3 incrustations. We then rinsed the samples Plants 2021, 10, 1581 3 of 13 with distilled water and dried them at 60 ◦C for 48 h. We ground the samples to a powder using liquid nitrogen and a mortar. Moss C and N concentration and δ13C and δ15N were determined by using a Flash EA1112 and TC/EA coupled to a stable isotope mass spectrometer Delta C through a Conflo III interface (ThermoFinnigan). We determined the concentration of 19 elements, including macro-, micronutrients and trace elements (P, K, S, Ca, Mg, Na, B, Fe, As, Al, Cd, Co, Cu, Cr, Hg, Mn, Ni, Pb, and Zn) by inductively coupled plasma mass/optical emission

    Molecular Phylogeny of Chinese Thuidiaceae with emphasis on Thuidium and Pelekium QI-YING, CAI1, 2, BI-CAI, GUAN2, GANG, GE2, YAN-MING, FANG 1 1 College of Biology and the Environment, Nanjing Forestry University, Nanjing 210037, China. 2 College of Life Science, Nanchang University, 330031 Nanchang, China. E-mail: [email protected] Abstract We present molecular phylogenetic investigation of Thuidiaceae, especially on Thudium and Pelekium. Three chloroplast sequences (trnL-F, rps4, and atpB-rbcL) and one nuclear sequence (ITS) were analyzed. Data partitions were analyzed separately and in combination by employing MP (maximum parsimony) and Bayesian methods. The influence of data conflict in combined analyses was further explored by two methods: the incongruence length difference (ILD) test and the partition addition bootstrap alteration approach (PABA). Based on the results, ITS 1& 2 had crucial effect in phylogenetic reconstruction in this study, and more chloroplast sequences should be combinated into the analyses since their stability for reconstructing within genus of pleurocarpous mosses. We supported that Helodiaceae including Actinothuidium, Bryochenea, and Helodium still attributed to Thuidiaceae, and the monophyletic Thuidiaceae s. lat. should also include several genera (or species) from Leskeaceae such as Haplocladium and Leskea. In the Thuidiaceae, Thuidium and Pelekium were resolved as two monophyletic groups separately. The results from molecular phylogeny were supported by the crucial morphological characters in Thuidiaceae s. lat., Thuidium and Pelekium. Key words: Thuidiaceae, Thuidium, Pelekium, molecular phylogeny, cpDNA, ITS, PABA approach Introduction Pleurocarpous mosses consist of around 5000 species that are defined by the presence of lateral perichaetia along the gametophyte stems. Monophyletic pleurocarpous mosses were resolved as three orders: Ptychomniales, Hypnales, and Hookeriales (Shaw et al.

  • 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.

    J Hattori Bot. lab. No. 75: 15- 22 (Feb. 1994) A RE-EVALUATION OF FISSJDENS SUBGENUS PACHYFISSJDENS, WITH A DETAILED DISCUSSION OF FISSIDENS GRANDIFRONS AND F GEIJSKESII 1 2 RONALD A. PURSELL AND BRUCE H. ALLEN ABSTRACT . Subgenus Pachyfissidens, lectotypified by Fissidens grandifrons Brid., is based essen­ tially on plants with stiff leaves and pluristratose laminal cells. It is an unnatural and taxonomically superfluous taxon. Species assigned to this subgenus are placed in subgenus Fissidens section Aloma C. Miill. (Fissidens sedgwickii Broth. & Dix.), section Amblyothallia C. Miill. (Fissidens grandifrons Brid.), section Crispidium C. Miill. (Fissidens strictus Hook. f. & Wits.), and section Fissidens (Fissi­ dens rochensis Broth. and F. ventricosus Lesq.), subgenus Serridium (C. Miill.) lwats. (Fissidens boninensis lwats., F. jaiorum Whitt. & Mill., and F. perdecurrens Besch.), and subgenus Sarawakia (C. Miill.) lwats. (Fissidens geijskesii Florsch.). Pachyfissidens, established as a section of Fissidens Hedw. by Muller (l 848), was rec­ ognized as a subgenus by Kindberg ( 1897) and later accepted at this level by Brotherus ( 1901, 1924) in his widely adopted system of classfication. The taxon is distinguished by its rigid leaves, pluristratose laminal cells, an absence of a central strand in the stem, and estomate capsules. Pachyfissidens is here lectotypified with Fissidens grandifrons Brid., Sp. Muse. I : 170. 1806. (Lectotype. In Nova Anglia habitat, without collector, B). Bruggeman-Nannenga (1974) demonstrated that the pluristratose lamina! cells and lack of a central strand are also found in species that unquestionably belong to subgenus Fissidens. Furthermore, estomate capsules are found in the subgenera Octodiceras (Brid.) Broth. and Sarawakia (C. Miill.) lwats., with both stomate and estomate capsules occuring in some members of the latter subgenus.
