The health of plants in general and deciduous trees in particular is influenced by a variety of factors, including abiotic and biotic factors. Uncountable harmful organisms can lead to a weakening of deciduous trees and shrubs in forests and urban green, which are worth protecting due to their longevity and the invaluable ecosystem services they provide, as well as their high economic value. In this context, plant viruses play a major role and must be considered. Due to their ability to affect the host metabolism for the purpose of their own replication, they can influence the vitality of trees, change their susceptibility to other stress factors and thus lead to economic and ecological losses. In recent years, established technologies in the field of sequencing and bioinformatics have revealed the high abundance and enormous diversity of viruses in forest trees. New viruses of the genus Emaravirus have been discovered in numerous hosts, including herbaceous and woody plants. Especially in deciduous trees, emaraviruses have become the most widespread virus group causing diseases in important species of temperate and boreal forests. In this doctoral thesis, genetic and biological aspects of novel viruses were studied, with special focus on the emerging group of emaraviruses. Using the case studies common oak (Quercus robur L.) and common ash (Fraxinus excelsior L.), epidemiological studies revealed a wide distribution of common oak ringspot-associated virus (CORaV) and ash shoestring-associated virus (ASaV) in forest and urban trees. CORaV and ASaV can be differentiated from other pathogens based on specific leaf symptoms. With the help of a newly developed diagnostic ELISA, CORaV can be reliably detected serologically in diseased oak trees. A new species of rust mite is likely to be the vector for virus transmission. Based on the results considering the composition of emaraviral accessory proteins, the taxonomic order of the genus Emaravirus can be revised. In addition to ASaV, cytorhabdoviruses were shown to frequently infect common ash in natural and managed forest sites. Genetic characterization provided evidence for two distinct cytorhabdovirus species affecting not only Fraxinus excelsior, but also manna ash (Fraxinus ornus) and red ash (Fraxinus pennsylvanica). Applying High-throughput sequencing (HTS) analyses, sequence information about novel viruses belonging to different families have been revealed. The doctoral thesis provides new insights into the diverse virome of deciduous trees, thereby highlighting the demand for further studies on this fascinating group of pathogens. Their characterization and interaction with other abiotic and biotic stressors may serve as a basis for better disease management concepts of essential long-living trees in the future.

Ressourcenschonende Produktion und die nichtchemische Bekämpfung von Schaderregern gewinnen auch aufgrund politischer Entwicklungen weltweit an Bedeutung. Während Nahrungsmittel erzeugende Disziplinen wie Obst-, Gemüse- oder Weinbau über langjährige Erfahrungen zu wissenschaftlich begleiteten Praxisvorhaben in integrierten Pflanzenschutzsystemen verfügen, sind in Baumschulkulturen erprobte Konzepte rar. Im Rahmen dieser Dissertation wurde unter weitgehendem Verzicht auf chemisch-synthetische Pflanzenschutzmittel eine auf die Förderung und Etablierung von natürlichen Gegenspielern ausgelegte extensive Bewirtschaftung im Vergleich zu konventionellen Produktionsmethoden an Kaiserlinden (Tilia x europaea ‘Pallida‘) unter Praxisbedingungen erprobt. Wissenschaftlich untersucht wurden die Auswirkungen der Produktion auf Abundanz und Diversität von Nutz- und Schadarthropoden, Gesundheit und Wachstum der Bäume sowie ökonomische Parameter. Basierend auf den Erkenntnissen der mehrjährigen Praxisversuche sowie einer intensiven branchenübergreifenden Literaturrecherche wurde ein innovatives System zur nachhaltigen, ressourcenschonenden Gehölzproduktion als Handlungsempfehlung für die Praxis und künftige Forschungsvorhaben entwickelt.

Succession-nothing in plant, community, or ecosystem ecology has been so elaborated by terminology, so much reviewed, and yet so much the center of controversy. In a general sense, every ecologist uses the concept in teaching and research, but no two ecologists seem to have a unified concept of the details of succession. The word was used by Thoreau to describe, from a naturalist's point of view, the general changes observed during the transition of an old field to a forest. As data accumulated, a lengthy taxonomy of succession developed around early twentieth century ecologists such as Cooper, Clements, and Gleason. Now, nearer the end of the century, and after much discussion concerning the nature of vegetation communities, where do ecologists stand with respect to knowledge of ecological succession? The intent of this book is not to rehash classic philosophies of succession that have emerged through the past several decades of study, but to provide a forum for ecologists to present their current research and present-day interpretation of data. To this end, we brought together a group of scientists currently studying terrestrial plant succession, who represent research experience in a broad spectrum of different ecosystem types. The results of that meeting led to this book, which presents to the reader a unique summary of contemporary research on forest succession.

One of the main problems and aims of nature conservation in Europe is to protect semi-open landscapes. The development during the past decades is characterized by an ongoing intensivation of land use on the one hand, and an increasing number of former meadows and pastures lying fallow caused by changing economic conditions on the other hand. In several countries the estabishment of larger "pasture landscapes" with a mixed character of open grassland combined with shrubs and forests has been recognized as one solution to this problem. The book gives an overview of the European projects concerning to this topic - nature conservation policy and strategies, scientific results and practical experiences creating large scale grazing systems.

Landscape ecology is an integrative and multi-disciplinary science and Principles and Methods in Landscape Ecology reconciles the geological, botanical, zoological and human perspectives. In particular ,new paradigms and theories such as percolation, metapopulation, hierarchies, source-sink models have been integrated in this last edition with the recent theories on bio-complexity, information and cognitive sciences. Methods for studying landscape ecology are covered including spatial geometry models and remote sensing in order to create confidence toward techniques and approaches that require a high experience and long-time dedication. Principles and Methods in Landscape Ecology is a textbook useful to present the landscape in a multi-vision perspective for undergraduate and graduate students of biology, ecology, geography, forestry, agronomy, landscape architecture and planning. Sociology, economics, history, archaeology, anthropology, ecological psychology are some sciences that can benefit of the holistic vision offered by this texbook.
