Book Description
"The combination of natural habitat loss and the introduction of invasive exotic animal and plant species is creating environmental chaos. Because of the magnitude of the problem and the urgent need for action, the Indiana Academy of Science (IAS) organized this symposium. The conference dealt with both aquatic and terrestrial systems, with specific focus on causes, control measures, management practices, ecologic and economic consequences, and policy." "The Academy was founded in 1885 and deals with both biological and physical science. The IAS is dedicated to promote scientific research and the diffusion of scientific information; to encourage communication and cooperation among scientists; to improve education while stimulating interest in the sciences. It does so by offering research grants, sponsoring education activities and organizations, publishing a journal and books, and presenting special topic conferences."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Book Description
Fungi enjoy great popularity in pharmaceutical, agricultural, and biotechnological applications. Recent advances in the decipherment of whole fungal genomes promise an acceleration of these trends. This timely book links scientists from different parts of the world who are interested in the molecular identification of fungi combined with the exploration of the fungal biodiversity in different ecosystems. It provides a compendium for scientists who rely on a rapid and reliable detection of fungal specimens in environmental as well as clinical resources in order to ensure the benefit of industrial and clinical applications. Chapters focus on the opportunities and limits of the molecular marker-mediated identification of fungi. Various methods, procedures and strategies are outlined. Furthermore, the book offers an update of the current progress in the development of fungal molecular techniques, and draws attention to potential and associated problems, as well as integrating theory and practice.

Book Description
The Fernow Watershed Acidification Study is a long-term, paired watershed acidification study. This book describes the responses to chronic N and S amendments by deciduous hardwood forests, one of the few studies to focus on hardwood forest ecosystems. Intensive monitoring of soil solution and stream chemistry, along with measurements of soil chemistry, and vegetation growth and chemistry, provide insights into the acidification process in forested watersheds.

Book Description
Cytospora species and their Valsa teleomorphs are commonly found on Eucalyptus trees and some of these have been associated with stem canker diseases. The taxonomy of these fungi has been confused and has in many cases hindered pathology studies. This study was based on extensive collections of Cytospora species and their teleomorphs from Eucalyptus trees in Africa, Australia, Central and South America, Southeast Asia and California. Sixty-two Cytospora and three Cytospora-like isolates from Eucalyptus, yielding 33 unique ITS-rDNA sequences, were compared for homology to Cytospora species from other hosts. Phylogenetic analysis clustered isolates of Cytospora from Eucalyptus into at least 15 unrelated groups. The Cytospora-like isolates that morphologically resembled Cytospora clustered in a separate group, which is related to Phomopsis. Morphology of the fungi was examined on natural subtrates and in culture in order to identify distinctive characters linked to the phylogenetic lineages emerging from DNA sequence analyses. The specimens from Eucalyptus included morphological features encompassing the Cytospora infrageneric sections Cytospora, Lamyella, Leucocytospora, and Torsellia with the majority residing in sect. Lamyella. Several species exhibited morphological characteristics of more than one section and other species had unique characteristics not represented in the established sections. Phylogenetic inference did not support the sections that have been established based on morphological characteristics. The concepts underlying the establishment of sections in Valsa and Cytospora were, therefore, discarded and descriptive terms have been introduced to distinguish between ascostroma and locule forms. Descriptions of Cytospora australiae, C. eucalyptina, C. eucalypticola, and the anamorphs of Valsa eucalypti and Leucostoma sequoiae have been emended based on morphological studies of cross-sections of holotype and isotype specimens. Teleomorphs associated with Cytospora specimens on Eucalyptus have been described from Australia, California, Chile, Congo, Hawaii, India and Uganda. Each teleomorph had unique morphological characteristics and DNA sequence but several conformed to the broad description of Valsa ceratosperma, even though they resided in separate phylogenetic lineages. Additionally, sequences for V. ceratosperma on hosts other than Eucalyptus resided in separate lineages and were different from all of the isolates from Eucalyptus. One of the lineages, commonly found on Quercus, was recognised as corresponding to the original species concept and was designated as V. ceratosperma sensu stricto (= V. ceratophora). Results of this study have shown that numerous genetically distinct lineages of Cytospora and Cytospora-like fungi occur on Eucalyptus, and that the current description of V. ceratosperma encompases several distinctly different fungi. Leucostoma sequoiae and V. eugeniae were found on Eucalyptus, and V. eucalypti and L. sequoiae have been synonymised. Cultural characteristics including colony colour, pycnidium structure, cardinal temperatures for growth, and tolerance to cycloheximide have been described for the species. Several new species of Valsa and Cytospora from Eucalyptus have also been delimited based on morphological characteristics. This wide-ranging study should contribute to a better understanding of the taxonomy of Cytospora spp. and their teleomoprhs, particularly on Eucalyptus. It is also hoped that this will lead to improved management strategies for diseases associated with these fungi.
