Pyrenocarpous Lichens with Bitunicate Asci by André Aptroot Pdf
This publication provides an extensive treatment of the pyrenocarpous lichens with bitunicate asci (excluding Porinaceae, Myeloconidaceae and chiefly saxicolous genera) in Costa Rica, with keys, descriptions, and taxonomic discussion. A total of 181 species is treated, the majority of which are reported from the country for the first time, and several taxa are new to the Neotropics. Names reported or listed by earlier authors, in particular those by Müller Argoviensis and Dodge in the late 19th and early 20th century, were critically revised, and many turned out to belong to other taxa.
The Lichens covers the structure and development, physiology of the intact thallus, environmental response and effects, secondary metabolic products, and symbiont interactions of lichens. This book is divided into five parts encompassing 19 chapters. It also includes appendices consist of a taxonomic scheme, methods for isolating and culturing lichen symbionts and thalli, and methods for isolating and identifying lichen substances. The first part of this book describes the original fungal cell and its development into specialized cells of which the various tissues and thalli are composed. This is followed by discussions on sexual reproduction of ascolichens and basidiolichens and on systematic criteria for the definition of taxa in different hierarchical steps. This book also explains the types of propagules produced by lichens and the submicroscopical investigations of lichens, including phycobiont and mycobionts' substructure and symbiotic relationship. The second part of this book examines the physiological aspects of lichens. It includes discussions on metal cation uptake and translocation in vascular plants and on lichens' role in rock weathering and soil formation. This part also studies photosynthetic rates and nitrogen absorption and metabolism by the intact thallus of lichens. Succeeding chapters discuss physiological and morphological responses of lichens to the most important environmental factors and the relationship of these factors to lichen distribution. Substrate preferences of lichens and their causes and implications with regard to the ecology, distribution, and taxonomy of lichens are also examined. This text also discusses lichen thalli growth, methods of measurement, and factors influencing growth. Finally, the concluding parts deal with the biosynthesis of lichen substances, secondary metabolic products, and symbiotic relations of lichens to fungi and algae. This multi-authored book is an ideal source of information for researchers, teachers, and students who wish to broaden their knowledge in the diversity of lichenology.
Flora and Vegetation of the Pantanal Wetland by Geraldo Alves Damasceno-Junior,Arnildo Pott Pdf
This book will present information on Pantanal vegetation including an updated checklist of flora, useful plants, ecological aspects and some topics never published for this region, such as lichens. It aims to be a reference for researchers, graduate and undergraduate students as well as stakeholders and decision makers interested in the flora and vegetation of one of the world’s largest tropical wetlands.
Systematics and Evolution by David J. McLaughlin,Joseph W. Spatafora Pdf
This volume includes treatments of systematics and related topics for both fungi and fungus-like organisms in four eukaryotic supergroups, as well as specialized chapters on nomenclature, techniques and evolution. These organisms are of great interest to mycologists, plant pathologists and others, including those interested in the animal parasitic Microsporidia. Our knowledge of the systematics and evolution of fungi has made great strides since the first edition of this volume, largely driven by molecular phylogenetic analyses. Consensus among mycologists has led to a stable systematic treatment that has since become widely adopted and is incorporated into this second edition, along with a great deal of new information on evolution and ecology. The systematic chapters cover occurrence, distribution, economic importance, morphology and ultrastructure, development of taxonomic theory, classification, and maintenance and culture. Other chapters deal with nomenclatural changes necessitated by revisions of the International Code of Nomenclature for algae, fungi and plants, including the elimination of separate names for asexual states, as well as methods for preservation of cultures and specimens, character evolution and methods for ultrastructural study, the fungal fossil record, and the impact of whole genomes on fungal studies.
Biodiversity and Ecology of Lichens by André Aptroot,M. R. D. Seaward,Laurens B. Sparrius Pdf
This volume on lichen biodiversity and ecology is dedicated to Harrie Sipman. It contains 29 peer-reviewed contributions by 50 authors. The emphasis is on the biodiversity and ecology of lichens in the tropics, but some papers are devoted to related areas. This volume is indispensable for active lichenologists, especially because it contains keys to several lichen genera. Full monographs are presented for the reinstated genus Herpothallon (with 29 species), the new genera Diaphorographis (with 2 species), Sipmaniella (with 1 species) and Synarthothelium (with 2 species), and the genus Placopyrenium (with 14 species and 3 varieties). Keys are furthermore given to all cryptothalline species of Lecidea, the lichenicolous genus Sphaerellothecium and the species of Cryptothecia and Stirtonia in Thailand. The genus Trypetheliopsis is resurrected for Musaespora, and all relevant combinations are made. Most papers describe various new species from all over the world, in the genera Bacidia, Buellia, Caloplaca, Chapsa, Cladonia, Cryptothecia, Diaphorographis, Gassicurtia, Herpothallon, Micarea, Phaeographis, Placocarpus, Placopyrenium, Porina, Pyrenula, Pyxine, Stirtonia, Strigula, Synarthothelium, Thelocarpon, Thelopsis, Xanthoparmelia, and Zwackhiomyces. The newly described Thelopsis is intermediate between that genus and Topelia, leading to the supposition that these genera are one continuum and should be united. Floristic papers are presented on lichens from Montenegro, Korea, Japan, Thailand, Namibia (including the description of an association), South Africa and the Seychelles and bryophytes of the Galapagos, but specimens from a multitude of other countries ranging from Iceland to Australia are cited throughout the papers. The floristic papers contain also new synonymys and combinations, partly in additional genera like Mycomicrothelia. One paper is devoted to lichens and global warming. The volume also contains three phylogenetic studies, viz. on all lichen groups with cyanobacteria, on Schistophoron and on Tylophoron, in which a systematic placement for this enigmatic genus is postulated for the first time. The volume is completed by lists of published papers and species decribed by Harrie Sipman. The volume is richly illustrated and contains many colour photographs, e.g. from all Herpothallon species and from sections through the apothecia of many Lecidea species.
Evolution of Fungi and Fungal-Like Organisms by Stefanie Pöggeler,Johannes Wöstemeyer Pdf
Based on sequence analyses of many different genes, the past decade has provided us with a profound knowledge of fungal systematics and phylogeny. In addition, a number of sequences of complete fungal genomes have been identified and several others will soon follow. In this volume, leading experts address questions concerning the origin of the fungal kingdom and fungal evolution at a level of analytical refinement that has never been possible before. The following major aspects are highlighted: evolutionary roots of fungi; evolution of signaling in fungi and fungal-like organisms; evolution of mutualistic systems and metabolism in fungi; and evolutionary mechanisms and trends.
