Phytotaxa, a Synthesis of Hornwort Diversity

Despite their low species numbers, hornworts represent a key group for understanding the evolution of plant form because the best–sampled current phylogenies place them as sister to the tracheophytes. Despite their low taxonomic diversity, the group has not been monographed worldwide. There are few well-documented hornwort floras for temperate or tropical areas. Moreover, no species level phylogenies or population studies are available for hornworts. Here we aim at filling some important gaps in hornwort biology and biodiversity. We provide estimates of hornwort species richness worldwide, identifying centers of diversity. We also present two examples of the impact of recent work in elucidating the composition and circumscription of the genera Megaceros and Nothoceros. -

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. -

Forrest1 Received: 2 May 2019 / Accepted: 13 March 2020 / Published online: 4 April 2020 © Springer-Verlag GmbH Austria, part of Springer Nature 2020 Abstract The hornwort Anthoceros agrestis is emerging as a model system for the study of symbiotic interactions and carbon fixation processes. It is an annual species with a remarkably small and compact genome. Single accessions of the plant have been shown to be related to the cosmopolitan perennial hornwort Anthoceros punctatus. We provide the first detailed insight into the evolutionary history of the two species. Due to the rather conserved nature of organellar loci, we sequenced multiple accessions in the Anthoceros agrestis–A. punctatus complex using three nuclear regions: the ribosomal spacer ITS2, and exon and intron regions from the single-copy coding genes rbcS and phytochrome. We used phylogenetic and dating analyses to uncover the relationships between these two taxa. Our analyses resolve a lineage of genetically near-uniform European A. agrestis accessions and two non-European A. agrestis lineages. In addition, the cosmopolitan species Anthoceros punctatus forms two lineages, one of mostly European accessions, and another from India. All studied European A. agrestis accessions have a single origin, radiated relatively recently (less than 1 million years ago), and are currently strictly associated with agroecosystem habitats. -

O. Box 299, St. Louis, MO 63166–0299 U.S.A.; [email protected] Abstract A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast applications. An index of published names of liverworts and hornworts between 2009 and 2010 is provided as part of a continued effort in working toward producing a world checklist of this group. Included in the list are also names overlooked by earlier indices. The list includes 30 higher taxa, 250 species, 52 infraspecific taxa, 31 autonyms, and two fossils for 2009 and 2010. A number of taxa not covered by the earlier indices for 2000-2008 are also included. Key words: Liverworts, hornworts, index, nomenclature Introduction Under the auspices of the Early Land Plants Today project, there has been a strong community-driven effort attempting to address the critical need to synthesize the vast nomenclatural, taxonomic and global distributional data for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) (von Konrat et al. 2010a). These endeavours are critical in providing the foundation to develop a working checklist of liverworts and hornworts worldwide; the first version is projected to be published in 2012. -

Five species and one variety are recognized. Anthoceros alpinus, A. bharadwajii, and A. subtilis, are reported new to China. Aspiromitus areolatus and Anthoceros esquirolii are proposed as new synonyms of Folioceros fuciformis and Phaeoceros carolinianus, respectively. A key to the species of Anthoceros in China is provided. Key words: Anthoceros alpinus, A. bharadwajii, A. subtilis, hornworts, new synonym Introduction Hornworts (Anthocerotophyta) represent a key group in the understanding of evolution of plant form because they are hypothesized to be sister to the tracheophytes (Qiu et al. 2006). An estimate of 200–250 species of hornworts exist worldwide (Villarreal et al. 2010; Garcia et al. 2012; Villarreal et al. 2012). Anthoceros Linnaeus (1753: 1139) is the largest genus of hornworts, with ca. 83 species (Villarreal et al. 2010). With a global distribution, the centres of diversity in the genus are in the Neotropics and tropical Africa and Asia. -
Sporoderm Ultrastructure in Anthoceros Agrestis Paton Ультраструктура Спородермы Anthoceros Agrestis Paton Svetlana V

ПОЛЕВОВА1 Abstract The sporoderm ultrastructure in Anthoceros agrestis Paton is unique. The wall of mature spores consists of granules varying in size and shape, and does not have any homogenеous or lamellar layers. The electron-lucent sporopollenin, which forms granules of the exosporium, is comparable to that in other spore-bearing plants (mosses, liverworts and Pteridophyta) in its electron density, while it is different in structure. Electron-dense substances in the gaps between the exosporium granules are resistant to acetolysis and are probably sporopolleninous. Резюме Спородерма Anthoceros agrestis Paton характеризуется уникальной ультраструктурой. Оболочка зрелых спор построена из разнообразных по размеру и очертаниям гранул и не имеет гомогенных или ламеллятных слоев.

310 Arctic Biodiversity Assessment Purple saxifrage Saxifraga oppositifolia is a very common plant in poorly vegetated areas all over the high Arctic. It even grows on Kaffeklubben Island in N Greenland, at 83°40’ N, the most northerly plant locality in the world. It is one of the first plants to flower in spring and serves as the territorial flower of Nunavut in Canada. Zackenberg 2003. Photo: Erik Thomsen. 311 Chapter 9 Plants Lead Authors Fred J.A.
