The Aloineae, a tribe of several hundred species of succulent plants of the lily family, are ideal subjects for the study of karotypes and chromosome irregularities. This book brings together the major findings of a half-century of study of the Aloineae, with regard to polyploidy, aneuploidy, deletions, duplications, inversions, and translocations in the group. The possible evolutionary effects of ecological relationships, natural hybridization, and morphological changes during growth are also assessed. Illustrations include maps, diagrams, photographs, photomicrographs, and electron micrographs.

How can environmental degradation be stopped? How can it be reversed? And how can the damage already done be repaired? The authors of this volume argue that a two-pronged approach is needed: reducing demand for ecosystem goods and services and better management of them, coupled with an increase in supply through environmental restoration. Restoring Natural Capital brings together economists and ecologists, theoreticians, practitioners, policy makers, and scientists from the developed and developing worlds to consider the costs and benefits of repairing ecosystem goods and services in natural and socioecological systems. It examines the business and practice of restoring natural capital, and seeks to establish common ground between economists and ecologists with respect to the restoration of degraded ecosystems and landscapes and the still broader task of restoring natural capital. The book focuses on developing strategies that can achieve the best outcomes in the shortest amount of time as it: • considers conceptual and theoretical issues from both an economic and ecological perspective • examines specific strategies to foster the restoration of natural capital and offers a synthesis and a vision of the way forward Nineteen case studies from around the world illustrate challenges and achievements in setting targets, refining approaches to finding and implementing restoration projects, and using restoration of natural capital as an economic opportunity. Throughout, contributors make the case that the restoration of natural capital requires close collaboration among scientists from across disciplines as well as local people, and when successfully executed represents a practical, realistic, and essential tool for achieving lasting sustainable development.

Aloes are a large genus of plants, about 450 species, from sub-Saharan Africa, Madagascar, and parts of Arabia. Many species are widespread in warm or tropical semi-arid regions, yet the distribution of others is limited to a few living in desert or wet mountainous regions. While some species have been adopted as medicinal plants since ancient time
