This atlas presents a concrete tool to identify xylophagous activity by the remains they left in wooded areas in Western Europe. Xylophagous insects are among the largest predators of woody tissues. They leave discriminating traces, different for each species according to their bioecology, and so it is necessary to know how to recognize and characterize them. The book is a practical tool to help identify and interpret them through a standardized presentation of the most ubiquitous families and a key to their determination. It presents descriptions of the galleries and of morphometry of the faecal pellets based on macroscopic features for xylophagous identification, and includes information about the origin and distribution of the xylophagous biological cycles, bioclimatic conditions and bioecology, and the type of woods that are attacked. The book will be a useful guide for forest managers, heritage conservationists, environmental engineers, bioarchaeologists, entomologists, loggers, and wood anatomists.

This book is devoted to the ichnology of insects, and associated trace fossils, in soils and paleosols. The traces described here, mostly nests and pupation chambers, include one of the most complex architectures produced by animals. Chapters explore the walls, shapes and fillings of trace fossils followed by their classifications and ichnotaxonomy. Detailed descriptions and interpretations for different groups of insects like bees, ants, termites, dung beetles and wasps are also provided. Chapters also highlight the the paleoenvironmental significance of insect trace fossils in paleosols for paleontological reconstructions, sedimentological interpretation, and ichnofabrics analysis. Readers will discover how insect trace fossils act as physical evidence for reconstructing the evolution of behavior, phylogenies, past geographical distributions, and to know how insects achieved some of the more complex architectures. The book will appeal to researchers and graduate students in ichnology, sedimentology, paleopedology, and entomology and readers interested in insect architecture.
The idea of the book “Science and Conservation for Museum Collections” was born as a result of the experience made by CNR-ISTEC (Faenza) in the implementation of a course for Syrian restorers at the National Museum in Damascus. The book takes into consideration archaeological artefacts made out of the most common materials, like stones (both natural and artificial), mosaics, ceramics, glass, metals, wood and textiles, together with less diffuse artefacts and materials, like clay tablets, goldsmith artefacts, icons, leather and skin objects, bones and ivory, coral and mother of pearl. Each type of material is treated from four different points of view: composition and processing technology; alteration and degradation causes and mechanisms; procedures for conservative intervention; case studies and/or examples of conservation and restoration. Due to the high number of materials and to the great difference between their conservation problems, all the subjects are treated in a schematic, but precise and complete way. The book is mainly addressed to students, young restorers, conservators and conservation scientists all around the world. But the book can be usefully read by expert professionals too, because nobody can know everything and the experts often need to learn something of the materials not included in their specific knowledge. Twenty- two experts in very different fields of activity contributed with their experience for obtaining a good product. All they are Italian experts, or working in Italy, so that the book can be seen as an exemplification on how the conservation problem of Cultural Heritage is received and tackled in Italy. —————————————————— SCIENCE AND CONSERVATION FOR MUSEUM COLLECTIONS INTRODUCTION 1 – PREVENTIVE CONSERVATION 1.1 Introduction 1.2 International standards and guidelines 1.3 Environment-material interaction 1.4 Microclimate and monitoring 1.5 Handling works of art 1.6 Exhibition criteria 1.7 MUSA project: intermuseum network for conservation of artistic heritage Bibliography Acknowledgements 2 – STONE ARTEFACTS 2.1 What conservation means 2.2 Natural Stones 2.3 Artificial stones 2.4 Deterioration of the stone 2.5 Cleaning of stone artefacts 2.6 Consolidation and Protection 2.7 Case studies Bibliography 3 – MOSAICS 3.1 Manufacturing techniques 3.2 History of the mosaic 3.3 Degradation of mosaic 3.4 Restoration of mosaics 3.5 Case study Bibliography 4 – CERAMICS 4.1 Ceramic technology 4.2 Technological classification of ceramics 4.3 Alteration and degradation processes 4.4 Ceramic conservation and restoration 4.5 Case studies 4.6 Examples of restoration Bibliography Acknowledgements 5 – CLAY TABLETS 5.1 Defnition 5.2 Deterioration 5.3 Conservative intervention 5.4 Case study: Syrian tablets Bibliography Acknowledgements 6 – GLASS 6.1 General information 6.2 Processing techniques 6.3 Glass deterioration 6.4 Glass conservation and restoration 6.5 Case studies Bibliography Acknowledgements 7 – METALS 7.1 Origin of metals 7.2 Manufacturing techniques 7.3 Conservation state of metals 7.4 Conservative intervention for metals 7.5 Case studies: Recovery of metallic artefacts from terracotta containers Bibliography Acknowledgements 8 – GOLDSMITH ARTEFACTS 8.1 Goldsmith’s metals 8.2 Enamels 8.3 Precious stones 8.4 Alteration and degradation 8.5 Conservative intervention 8.6 Case studies Bibliography 9 – WOOD ARTEFACTS 9.1 Characteristics of the wood 9.2 Working techniques 9.3 Degradation of wood 9.4 How to start restoring 9.5 Restoration of a small inlaid table 9.6 Restoration of a commemorating wooden tablet 9.7 The restoration of a seventeenth-century wooden crucifix Bibliography 10 – ICONS 10.1 The construction of icons 10.2 Degradation and damages of icons 10.3 Methods of conservation and restoration of icons 10.4 Examples of conservative interventions Bibliography 11 – TEXTILE FINDS 11.1 Morphology, characteristics and properties of textiles 11.2 Decay of textile fibres 11.3 Conservation treatments of archaeological textiles 11.4 Conservation practice: two case histories Bibliography Acknowledgements 12 – LEATHER AND ANIMAL SKIN OBJECTS 12.1 Introduction 12.2 Skin 12.3 The tanning process 12.4 Parchment 12.5 Leather degradation 12.6 Conservative intervention 12.7 Examples of conservative interventions Bibliography 13 – INORGANIC MATERIALS OF ORGANIC ORIGIN 13.1 The materials 13.2 The restoration operations 13.3 Cases of study Bibliography Acknowledgements 14 – ANALYTICAL TECHNIQUES 14.1 General information 14.2 Optical microscopy 14.3 Spectroscopic techniques 14.4 Radiochemical techniques 14.5 Chromatography 14.6 Electron microscopy 14.7 Thermal analyses 14.8 Open porosity measurements 14.9 Analysis of microbial colonization Bibliography Acknowledgements
Since prehistoric times and throughout the course of human evolution, wood has been an integral part of all civilizations. Wooden Cultural Heritage can be found worldwide, providing valuable information on the social and economic context of human history. Nonetheless, as a natural cellulosic material, wood shows low resistance to biodeterioration and thus wooden Cultural Heritage often fails to escape decomposition in both aquatic and terrestrial ecosystems. This book provides a comprehensive overview on the biodeterioration of wooden Cultural Heritage and describes the decay mechanisms of key organisms and microorganisms encountered in aquatic and terrestrial ecosystems. Cultural Heritage professionals, researchers and academics may explore within this book the associations between deteriogens, habitats and decay, which will assist them to understand wood biodeterioration and design effective prevention, mitigation and remediation strategies. The book presents case studies around the world to demonstrate the impact of biogenic deterioration on wooden Cultural Heritage and illustrates mechanisms and patterns in order to be a useful handbook of decay diagnosis. Lastly, by adopting a holistic approach to wood decay, basic concepts of wood technology, ecology, and deteriogens' biology are introduced, permitting readers of different scientific backgrounds to easily comprehend wood biodeterioration.
This book emphasizes the important message that architects and structural engineers must strive to ensure that the buildings they design and construct should not be major contributors to climate change. Rather, they should be exploring the use of green materials and building methods – such as timber, wood, and associated materials – in order to safeguard the environment. These sustainable materials are not only environmentally friendly, but they have the added benefit of being easy to manufacture, cost effective, often locally available, and easily replenished. Moreover, it has been demonstrated that wood and timber are viable materials in the construction of a wide variety of building types, including medium and high-rise buildings. The Importance of Wood and Timber in Sustainable Buildings brings together a distinguished group of contributors from different cultures and building traditions to address why now is the time to rethink our construction methods and explore replacing many of the carbon intensive materials that are currently being used with wood and timber.
Outside Russia very little is known about the terrestrial ecology, vegetation, biogeographical patterns, and biodiversity of the enormously extensive ecosystems of Yakutia, Siberia. These systems are very special in that they function on top of huge layers of permafrost and are exposed to very severe and extreme weather conditions, the range between winter and summer temperatures being more than 100 degrees C. The soils are generally poor, and human use of the vegetation is usually extensive. Main vegetation zones are taiga and tundra, but Yakutia also supports a special land and vegetation form, caused by permafrost, the alas: more or less extensive grasslands around roundish lakes in taiga. All these vegetation types will be described and their ecology and ecophysiological characteristics will be dealt with. Because of the size of Yakutia, covering several climatic zones, and its extreme position on ecological gradients, Yakutia contains very interesting biogeographical patterns, which also will be described. Our analyses are drawn from many years of research in Yakutia and from a vast body of ecological and other literature in Russian publications and in unpublished local reports. The anthropogenic influence on the ecosystems will be dealt with. This includes the main activities of human interference with nature: forestry, extensive reindeer herding, cattle and horse grazing, etc. Also fire and other prominent ecological factors are dealt with. A very important point is also the very high degree of naturalness that is still extant in Yakutia’s main vegetation zones.
