Plant Collectors in Angola

An authoritative treatise on the history of botanical studies and exploration in Angola. For any region, cataloging, interpreting, and understanding the history of botanical exploration and plant collecting, and the preserved specimens that were amassed as a result, are critically important for research and conservation. In this book, published in cooperation with the International Association for Plant Taxonomy, Estrela Figueiredo and Gideon F. Smith, both botanists with expertise in the taxonomy of African plants, provide the first comprehensive, contextualized account of plant collecting in Angola, a large country in south-tropical Africa. An essential book for anyone concerned with the biodiversity and history of Africa, this authoritative work offers insights into the lives, times, and endeavors of 358 collectors. In addition, the authors present analyses of the records that accompanied the collectors’ preserved specimens. Illustrated in color throughout, the book fills a large gap in the current knowledge of the botanical and exploration history of Africa.

The conservation of historic monuments, sites and structures constitutes an inter-professional discipline co-ordinating a range of aesthetic historic, scientific and technical methods. Conservation is a rapidly developing field, which, by its true nature, is a multidisciplinary activity with experts respecting one another's contributions and combining to form an effective team. Conservation is an artistic activity aided by scientific and historical knowledge. Main topics at this Congress included: - the most appropriate methodology for the assessment of the degree of weathering of stone - development of new methods and instruments for the diagnosis of the state of conservation, for the study of alteration mechanisms and for conservation treatments. - the definition of Technical European Standard Methods for the evaluation of conservation treatments of artistic and historic stone objects and monuments.

Common Names of Angolan Plants presents an updated and expanded catalogue of several thousand common names recorded for the indigenous and exotic floristic riches of Angola. Separate alphabetical lists of common names and accepted scientific names are provided and reference is made to the synonyms under which they were recorded. Where known, the languages are given throughout. The book provides biodiversity specialists and researchers in a broad spectrum of scientific and other endeavors, linguists, students and other stakeholders with the basic information on the common names of Angolan plants that has been unavailable for a long time. It represents a further critically important step towards assembling the knowledge of the flora of the country into a single, modern, easily accessible and scientifically sound framework.

Field Guide to Succulents of Southern Africa

Southern Africa is the natural home of the richest and most diverse succulent flora in the world. These plants come in all shapes and sizes, from trees such as the baobab at more than 20 m tall, to miniature soil huggers, just a few millimetres high, which mimic their pebble-desert surroundings. This user-friendly, richly illustrated field guide features more than 700 southern African succulents, focusing on the most interesting and commonly encountered species. An introduction to families and their key features will help readers identify the relevant plant group, while concise accounts describing the plants’ diagnostic features, along with distribution maps, will enable quick ID of species. More than just an ID guide for plant lovers, this book will inspire gardeners who are turning to indigenous, low-maintenance and waterwise plants for cultivation.

Succulent Paradise – Twelve great gardens of the world

Most botanical gardens include succulents in their collections; few are devoted solely to them. In Succulent Paradise, the reader is taken on a verbal and visual tour of twelve exceptional succulent gardens. See how a handful of landscaping and horticultural visionaries have juxtaposed indigenous and exotic plants with a blend of natural and created landscaping elements. Experience the impact and style of gardens in locations as diverse as steeply terraced Mediterranean cliffs, dusty Karoo plains, Mexico City’s metropolis, California’s canyons, and the red desert of Arizona. The authors have visited gardens around the world dedicated to the display, cultivation and propagation of succulent plants. In Succulent Paradise, they have expressed their love of these tenacious, yet surprisingly glamorous, plants as well as appreciation for those whose vision and persistence has variously created abundance, promoted conservation, and left a legacy for future generations.

Biodiversity of Angola

  • Publisher: Springer

This open access multi-authored book presents a 'state of the science' synthesis of knowledge on the biodiversity of Angola, based on sources in peer-reviewed journals, in books and where appropriate, unpublished official reports. The book identifies Angola as one of the most biologically diverse countries in Africa, but notes that its fauna, flora, habitats and the processes that drive the dynamics of its ecosystems are still very poorly researched and documented. This 'state of the science' synthesis is for the use of all students of Angola's biodiversity, and for those responsible for the planning, development and sustainable management of the country's living resources. The volume brings together the results of expeditions and research undertaken in Angola since the late eighteenth century, with emphasis on work conducted in the four decades since Angola's independence in 1975. The individual chapters have been written by leaders in their fields, and reviewed by peers familiar with the region.

Biodiversity of the Gulf of Guinea Oceanic Islands

This open access book presents a comprehensive synthesis of the biodiversity of the oceanic islands of the Gulf of Guinea, a biodiversity hotspot off the west coast of Central Africa. Written by experts, the book compiles data from a plethora of sources – archives, museums, bibliography, official reports and previously unpublished data – to provide readers with the most updated information about the biological richness of these islands and the conservation issues they face. The Gulf of Guinea Oceanic Islands (Príncipe, São Tomé and Annobón and surrounding islets) present extraordinary levels of endemism across different animal, fungi and plant groups. This very high endemism likely r...

Building Stone Decay

Stone buildings and monuments form the cultural centres of many of the world's urban areas. Frequently these areas are prone to high levels of atmospheric pollution that promote a variety of aggressive stone decay processes. Because of this, stone decay is now widely recognised as a severe threat to much of our cultural heritage. An interdisciplinary approach between geologists, environmental scientists, chemists, material scientists, civil engineers, restorers and architects aims to strengthen the knowledge base dealing with the causes, consequences, prevention and solution of stone decay problems.
