It’s how nature creates itself, on every scale, the snowflake and the snowstorm. — TOM STOPPARD, Arcadia, Act 1, Scene 4 (1993) Much has been written about evolution from the perspective of the history and biology of animals, but significantly less has been writ- ten about the evolutionary biology of plants. Zoocentricism in the biological literature is understandable to some extent because we are after all animals and not plants and because our self- interest is not entirely egotistical, since no biologist can deny the fact that animals have played significant and important roles as the actors on the stage of evolution come and go. The nearly romantic fascination with di- nosaurs and what caused their extinction is understandable, even though we should be equally fascinated with the monarchs of the Carboniferous, the tree lycopods and calamites, and with what caused their extinction (fig. 0.1). Yet, it must be understood that plants are as fascinating as animals, and that they are just as important to the study of biology in general and to understanding evolutionary theory in particular.

  • Liverworts of the Wellington Area J
    Liverworts of the Wellington Area J. E. Braggins1 LIVERWORT FEATURES Liverworts are plants similar in many ways to mosses: they are usually small, and generally lack the hard supporting tissues of larger plants such as ferns. Like ferns, liverworts show alternation of generations, having separate gametophyte and sporophyte entities; unlike ferns the sporophyte is not a separate plant. As with mosses, the gametophyte generation is the dominant phase of the life cy- cle, and the sporophyte generation is permanently dependent on it. Liverworts show a greater range in general morphology and form than mosses, and as well as normal leafy plants, there are dozens of species of thalloid liverworts that lack organisation into stems and leaves. The most striking differences between mosses and liverworts are in the sporophytes where liverworts have a simple outer wall lacking the peristome of mosses, and in the capsule which usually splits into four valves to release the spores. Mixed amongst the spores are hair- like elaters, which flick and twist as they dry out, helping to throw the spores clear. The stalk that bears the capsule (the seta) remains short until the capsule is mature, then, by cell elongation, it expands rapidly to its full size. Thus, the expanded seta of a liverwort is a delicate translucent structure, not tough and wiry like a moss seta which elongates slowly by cell growth. The vegetative parts of leafy liverworts differ from mosses in details of cell shape, contents, leaf structure (liverwort leaves lack a central nerve or vein), shape (liverwort leaves are rarely markedly elongate but are often complexly lobed) and position.

  • Identification of Conifer Trees in Iowa This Publication Is Designed to Help Identify the Most Common Trees Found in Iowa
    Identification of Conifer Trees in Iowa This publication is designed to help identify the most common trees found in Iowa. It is based on vegetative characteristics including leaves, fruit, and bark. It is neither complete nor without possible oversights. Separate species are grouped by similar characteristics, mainly based on type and arrangement of leaves. These groups are; awl- or scale- like needles; single needles, flattened with rounded tips; single needles, square in cross section, with pointed tips; and needles in bundles or fasticles of two or more. Remember, vegetative character- istics are quite variable; use more than one specimen for comparison. Awl- or scale-like needles Juniperus Virginiana Eastern Red Cedar Leaves are dark green; leaves are both awl- and scale-like; cone is dark blue and berry-like. Thuja occidentalis Northern White Cedar Leaves are flattened and only of the scale type; cones have 4-6 scales; foliage is light green. Juniperus communis Common Juniper Leaves are awl shaped; cone is dark blue and berry-like. Pm-1383 | May 1996 Single needles, flattened with rounded tips Pseudotsuga menziesii Douglas Fir Needles occur on raised pegs; 3/4-11/4 inches in length; cones have 3-pointed bracts between the cone scales.

Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.

NADEZDA A. KONSTANTINOVA1 & ANNA A. VILNET1 1Polar-Alpine Botanical Garden–Institute RAS, 184256, Kirovsk, Russia, email: [email protected], [email protected] Abstract The new species Jungermannia calcicola Konstant. et Vilnet, is described based on a critical reinvestigation of morphologi- cal features and molecular analyses of trnL–trnF and trnG intron cpDNA sequences of forty samples of Jungermannia s. str. The new species is described and illustrated as well as noting its differentiation from allied species and distribution patterns. New data on some taxonomical ambiguities and on the taxa delimitation in the Jungermannia s. str. are discussed. Key words: Jungermannia calcicola sp. nov., liverworts, taxonomy, molecular systematics, distribution Introduction Jungermannia Linnaeus (1753: 1131) is one of the oldest described genera of leafy liverworts. Since its description the treatment of this genus has been drastically changed. At the end of the 20th to the beginning of the 21st centuries most bryologists accepted Jungermannia in the wide sense including Solenostoma Mitten (1865a: 51), Plectocolea (Mitten 1865b: 156) Mitten (1873: 405), Liochlaena Nees in Gottsche et al. (1845: 150). But in recent molecular phylogenetic studies Jungermannia s. lat. has been proved to be a mixture of phylogenetically unrelated taxa, some of which have been elevated to distinct families, e.g., Solenostomataceae Stotler et Crand.-Stotl.

  • 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.

  • Multi-Gene Phylogeny Supports Single Origin of Jungermannioid Perigynium
    Ann. Bot. Fennici 44: 450–462 ISSN 0003-3847 (print) ISSN 1797-2442 (online) Helsinki 20 December 2007 © Finnish Zoological and Botanical Publishing Board 2007 Multi-gene phylogeny supports single origin of jungermannioid perigynium Xiaolan He-Nygrén Botanical Museum, Finnish Museum of Natural History, P.O. Box 7, FI-00014 University of Helsinki, Finland Received 23 Nov. 2006, revised version received 8 Feb. 2007, accepted 8 Feb. 2007 He-Nygrén, X. 2007: Multi-gene phylogeny supports single origin of jungermannioid perigynium. — Ann. Bot. Fennici 44: 450–462. Within the leafy liverworts, the evolution of the perigynium, the stem-derived struc- ture that protects the developing sporophytes, has been understood as merely a paral- lelism, and families that have this feature have been placed to various suborders. The present study suggests a single origin of the perigynium in the leafy liverworts and the presence of perigynium being a synapomorphy for the suborder Jungermanniineae. The phylogenetic analyses were conducted using thirty-four leafy liverworts including twelve genera bearing a perigynium, and sequence data for rbcL, rps4, trnL-F cpDNA and 26S nrDNA. Within the Jungermanniineae three monophyletic lineages are recog- nized: the Acrobolbaceae lineage, the Trichotemnomaceae–Balantiopsidaceae lineage, and the lineage consisting of Jungermanniaceae and its closest related Gymnomi- triaceae, Delavayellaceae, Geocalycaceae s. stricto, Antheliaceae, Calypogeiaceae and Gyrothyraceae. The long branches of the latter three families indicate that they are more isolated from a common jungermannioid ancestor. The family Jungermanniaceae is resolved as paraphyletic and its circumscription and relationships require further study. Key words: homology, Jungermanniineae, leafy liverworts, morphological innovation, perigynium, phylogeny, systematics Introduction rophyte.
