  • Checklist of the Liverworts and Hornworts of the Interior Highlands of North America in Arkansas, Illinois, Missouri and Oklahoma
    Checklist of the Liverworts and Hornworts of the Interior Highlands of North America In Arkansas, Illinois, Missouri and Oklahoma Stephen L. Timme T. M. Sperry Herbarium ‐ Biology Pittsburg State University Pittsburg, Kansas 66762 and 3 Bowness Lane Bella Vista, AR 72714 [email protected] Paul Redfearn, Jr. 5238 Downey Ave. Independence, MO 64055 Introduction Since the last publication of a checklist of liverworts and hornworts of the Interior Highlands (1997)), many new county and state records have been reported. To make the checklist useful, it was necessary to update it since its last posting. The map of the Interior Highlands of North America that appears in Redfearn (1983) does not include the very southeast corner of Kansas. However, the Springfield Plateau encompasses some 88 square kilometers of this corner of the state and includes limestone and some sandstone and shale outcrops. The vegetation is typical Ozarkian flora, dominated by oak and hickory. This checklist includes liverworts and hornworts collected from Cherokee County, Kansas. Most of what is known for the area is the result of collections by R. McGregor published in 1955. The majority of his collections are deposited in the herbarium at the New York Botanical Garden (NY). This checklist only includes the region defined as the Interior Highlands of North America. This includes the Springfield Plateau, Salem Plateau, St. Francois Mountains, Boston Mountains, Arkansas Valley, Ouachita Mountains and Ozark Hills. It encompasses much of southern Missouri south of the Missouri River, southwest Illinois; most of Arkansas except the Mississippi Lowlands and the Coastal Plain, the extreme southeastern corner of Kansas, and eastern Oklahoma (Fig.

  • Cyanobacteria in Terrestrial Symbiotic Systems
    Cyanobacteria in Terrestrial Symbiotic Systems Jouko Rikkinen Abstract Filamentous cyanobacteria are important primary producers and N2 fixers in many terrestrial environments. As reduced nitrogen is often limiting, some thalloid liverworts (Marchantiophyta), hornworts (Anthocerophyta), the water fern Azolla (Salviniales), cycads (Cycadophyta), and the angiosperm Gunnera (Gunnerales) have evolved the ability to establish stable and structurally well-defined symbioses with N2-fixing cyanobacteria. Also a wide diversity of lichen-forming fungi have cyanobacteria as photosynthetic symbionts or as N2-fixing symbionts. Cyanolichen symbioses have evolved independently in different fungal lineages, and evolution has often resulted in convergent morphologies in distantly related groups. DNA techniques have provided a wealth of new information on the diversity of symbiotic cyanobacteria and their hosts. The fact that many plants and fungi engage in many different symbioses simultaneously underlines the probable significance of diffuse evolutionary relationships between different symbiotic systems, including cyanobacterial and mycorrhizal associations. This review introduces the reader to recent research on symbiotic cyanobacteria in terrestrial ecosystems and shortly describes the astonishing range of diversity in these ecologically important associations. Introduction Mutually beneficial symbiotic interactions are an inherent feature of most ecological communities. Nitrogen is essential for growth of land plants, but the availability of reduced nitrogen in the soil is often limiting. Diazotrophic bacteria are able to convert atmospheric dinitrogen (N2) to ammonia (NH3) that can be utilized by plants, and consequently, numerous land plants form an association with N2-fixing bacteria. These interactions include the morphologically and physiologically highly coevolved symbioses between legumes and rhizobia, between actinorhizal plants and Frankia, and a plethora of more casual associations between plants and prokaryotic diazotrophs (Bothe et al.

  • Boreal Felt Lichen (Erioderma Pedicellatum), Boreal Population
    Species at Risk Act Management Plan Series Adopted under Section 69 of SARA Management Plan for the Boreal Felt Lichen – Boreal Population (Erioderma pedicellatum) in Canada Boreal Felt Lichen – Boreal Population 2010 About the Species at Risk Act Management Plan Series What is the Species at Risk Act (SARA)? SARA is the Act developed by the federal government as a key contribution to the common national effort to protect and conserve species at risk in Canada. SARA came into force in 2003, and one of its purposes is “to manage species of special concern to prevent them from becoming endangered or threatened.” What is a species of special concern? Under SARA, a species of special concern is a wildlife species that could become threatened or endangered because of a combination of biological characteristics and identified threats. Species of special concern are included in the SARA List of Wildlife Species at Risk. What is a management plan? Under SARA, a management plan is an action-oriented planning document that identifies the conservation activities and land use measures needed to ensure, at a minimum, that a species of special concern does not become threatened or endangered. For many species, the ultimate aim of the management plan will be to alleviate human threats and remove the species from the List of Wildlife Species at Risk. The plan sets goals and objectives, identifies threats, and indicates the main areas of activities to be undertaken to address those threats. Management plan development is mandated under sections 65-72 of SARA (www.sararegistry.gc.ca/approach/act/default_e.cfm).

Box 65, 00014, Helsinki, Finland A B S T R A C T We studied the genotype diversity of cyanobacterial symbionts in the predominately terricolous cyanolichen genus Peltigera (Peltigerales, Lecanoromycetes) in Estonia. Our sampling comprised 252 lichen specimens collected in grasslands and forests from different parts of the country, which represented all common Peltigera taxa in the region. The cyanobacteria were grouped according to their tRNALeu (UAA) intron sequences, and mycobiont identities were confirmed using fungal ITS sequences. The studied Peltigera species associated with 34 different “Peltigera-type” Nostoc trnL genotypes. Some Peltigera species associated with one or a few trnL genotypes while others associated with a much wider range of genotypes. Mycobiont identity was the primary factor that determined the presence of the specific Nostoc genotype within the studied Peltigera thalli. However, the species-specific patterns of cyanobiont selectivity did not always reflect phylogenetic relationships among the studied fungal species but correlated instead with habitat preferences. Several taxa from different sections of the genus Peltigera were associated with the same Nostoc genotype or with genotypes in the same habitat, indicating the presence of functional guild structure in the photobiont community.

  • Occurrence Networks Among Spatially Close Bacterial Microbiota of Bark, Mosses and Lichens
    Molecular Ecology (2017) doi: 10.1111/mec.14070 Differential sharing and distinct co-occurrence networks among spatially close bacterial microbiota of bark, mosses and lichens INES ALINE ASCHENBRENNER,* TOMISLAV CERNAVA,*† ARMIN ERLACHER,* GABRIELE BERG* and MARTIN GRUBE‡ *Institute of Environmental Biotechnology, Graz University of Technology, Petersgasse 12, 8010 Graz, Austria, †ACIB GmbH, Petersgasse 14, 8010 Graz, Austria, ‡Institute of Plant Sciences, University of Graz, Holteigasse 6, 8010 Graz, Austria Abstract Knowledge of bacterial community host-specificity has increased greatly in recent years. However, the intermicrobiome relationships of unrelated but spatially close organisms remain little understood. Trunks of trees covered by epiphytes represent complex habitats with a mosaic of ecological niches. In this context, we investigated the structure, diversity and interactions of microbiota associated with lichens, mosses and the bare tree bark. Comparative analysis revealed significant differences in the habitat-associated community structures. Corresponding co-occurrence analysis indi- cated that the lichen microbial network is less complex and less densely intercon- nected than the moss- and bark-associated networks. Several potential generalists and specialists were identified for the selected habitats. Generalists belonged mainly to Proteobacteria, with Sphingomonas as the most abundant genus. The generalists com- prise microorganisms with generally beneficial features, such as nitrogen fixation or other supporting functions, according to a metagenomic analysis. We argue that benefi- cial strains shared among hosts contribute to ecological stability of the host bio- coenoses.
