This Special Issue on the Systematics and Phylogeny of Weevils presents 31 new research papers on one of the most diverse and successful groups of animals on Earth, the beetle superfamily Curculionoidea. It was in part inspired to commemorate the extraordinary life and scientific achievements of Guillermo (“Willy”) Kuschel (1918–2017), who shaped this field of science over the last century like no other weevil systematist. The papers in this memorial issue span weevil faunas from all over the globe, including South and Central America, Africa, Europe and the Near East, South-East Asia, New Guinea, Australia and New Zealand. They include major advances on the phylogeny and classification of the “broad-nosed” weevils (Entiminae), on the weevils associated with American cycads and on the unique extinct weevil fauna preserved in the 100-million-year-old Burmese amber, when weevils started to diversify alongside the oldest angiosperm plants. They comprise a tribute to Willy Kuschel, the proceedings of a weevil symposium held in his honor in 2016 in Orlando, Florida, 24 systematic studies (including seven phylogenetic analyses) and five other contributions on the diversity, biology, distribution, evolution and fossil history of weevils. In the papers collated in this volume, 30 new genera and 92 new species of weevils are described and a new family of extinct weevils is recognized.

Many edible plants considered exotic in the Western world are actually quite mainstream in other cultures. While some of these plants are only encountered in ethnic food markets or during travels to foreign lands, many are now finding their way onto supermarket shelves. Top 100 Exotic Food Plants provides comprehensive coverage of tropical and semitropical food plants, reviewing scientific and technological information as well as their culinary uses. Wide-ranging in scope, this volume’s coverage includes plants that produce fruits, vegetables, spices, culinary herbs, nuts, and extracts. A user-friendly format enables readers to easily locate information on botanical and agricultural aspects, economic and social importance, food uses, storage, preparation, and potential toxicity. The book also contains an introductory chapter that reviews important historical, economic, geopolitical, health, environmental, and ethical considerations associated with exotic food plants. Thoroughly referenced with more than 2000 literature citations, this book is enhanced by more than 200 drawings, many chosen from historical art of extraordinary quality. This timely volume also highlights previously obscure edible plants that have recently become prominent as a result of sensationalistic media reports stemming from their inherently entertaining or socially controversial natures. Some of these plants include the acai berry, kava, hemp, and opium poppy. A scholarly yet accessible presentation, the book is filled with numerous memorable, fascinating, and humorous facts, making it an entertaining and stimulating read that will appeal to a broad audience.

Global Advances in Biogeography brings together the work of more than 30 scientific authorities on biogeography from around the world. The book focuses on spatial and temporal variation of biological assemblages in relation to landscape complexity and environmental change. Global Advances embraces four themes: biogeographic theory and tests of concepts, the regional biogeography of individual taxa, the biogeography of complex landscapes, and the deep-time evolutionary biogeography of macrotaxa. In addition, the book provides a trove of new information about unusual landscapes, the natural history of a wide array of poorly known plant and animal species, and global conservation issues. This book is well illustrated with numerous maps, graphics, and photographs, and contains much new basic biogeographical information that is not available elsewhere. It will serve as an invaluable reference for professionals and members of the public interested in global biogeography, evolution, taxonomy, and conservation.

“Public Gardens Management: A Global Perspective” provides essential information about public gardens and what is involved in designing, managing, and maintaining one. Although suitable as a textbook, its audience will include anyone with direct or peripheral responsibility for administration or supervision of a complex organization that requires scientific knowledge as well as public relations and business acumen. It may also prove useful for homeowners, for there is no fundamental difference between growing plants in a public garden or a home garden, a fact reflected in the extensive reference citations. The topic is multidisciplinary and as old as the beginning of human civilization when the concept of mental and physical restoration was realized by early man while he/she was in a natural but well-ordered garden environment. Thus began the art of garden making. Many volumes have been written on every applicable subject discussed in this and similar publications. Indeed the voluminous literature on history, design, horticulture, and numerous related subjects is nothing short of overwhelming. Accordingly, anyone involved in management of public gardens, whether as a director or area supervisor, and irrespective of the type and size of such facility, would have to have familiarity with various aspects of garden organization and administration. However, despite the enormous number and diversity of such publications there are very few books that deal with the multiplicity of the topics in such a manner as to be practical in approach and cover most relevant and unified issues in a single book. These volumes provide the essential background information on plants, animals, management, maintenance, fundraising and finances, as well as history, art, design, education, and conservation. They also cover a host of interrelated subjects and responsible organization of such activities as creating a children’s garden, horticultural therapy, conservatories, zoological gardens, and parks, hence, administration of multidimensional public gardens. Nearly 500 full color plates representing illustrations from gardens in more than 30 countries are provided to assist and guide students and other interested individuals with history and the fundamental issues of public garden management. The 15 chapters begin with the need for public gardens, types of public gardens, historical backgrounds, as well as design diversity. Numerous quotations are included from many garden lovers, landscape architects, philosophers, and others. The author’s primary aim in writing this book was based on the confidence that a relevant reference, between the encyclopedic nature of some and the specific subject matter of others, could be used to provide fundamental information for management of public as well as private gardens. The boundary between botanical and zoological gardens and parks is no longer as distinct as it once was. In part it is because a garden is not a garden without plants and in part it has become apparent that for all practical intents and purposes all animals need plants for their survival. Visitors of zoological gardens expect to see more than just animals; zoos are landscaped grounds. Moreover, most communities find it financially difficult to simultaneously operate a botanical garden or an arboretum as well as a zoological garden and city parks. A number of public gardens are currently referred to as “botanical and zoological garden.” Population density and the public’s desires and expectations, as well as financial requirements, are among the reasons for some major city parks, such as Golden Gate in San Francisco, Central Park in New York City, and Lincoln Park in Chicago which integrate botanical or zoological divisions as well as museums and recreational facilities. While this book attempts to provide basic principles involved in public garden management, it does not claim to be a substitute for broader familiarity

Positioned within current ecocritical scholarship, this volume is the first book-length study of the representations of plants in contemporary American, English, and Australian poetry. Through readings of botanically-minded writers including Les Murray, Louise Glück, and Alice Oswald, it addresses the relationship between language and the subjectivity, agency, sentience, consciousness, and intelligence of vegetal life. Scientific, philosophical, and literary frameworks enable the author to develop an interdisciplinary approach to examining the role of plants in poetry. Drawing from recent plant science and contributing to the exciting new field of critical plant studies, the author develops a methodology he calls "botanical criticism" that aims to redress the lack of emphasis on plant life in studies of poetry. As a subset of ecocriticism, botanical criticism investigates how poets engage with plants literally and figuratively, materially and symbolically, in their works. Key themes covered in this volume include plants as invasives and weeds in human settings; as sources of physical and spiritual nourishment; as signifiers of region, home, and identity; as objects of aesthetics and objectivism; and, crucially, as beings with their own perspectives, voices, and modes of dialogue. Ryan demonstrates that poetic imagination is as essential as scientific rationality to elucidating and appreciating the mysteries of plant-being. This book will appeal to a multidisciplinary readership in the fields of ecocriticism, ecopoetry, environmental humanities, and ecocultural studies, and will be of interest to researchers in the emerging area of critical plant studies.

The IUCN/SSC Cycad ACtion Plan brings together the best available information on this ancient and fascinating group of plants. Cycads were a dominant part of the earth's flora during the age of the dinosaurs and many species were common even in more recent times. However, many of the 297 species and subspecies dealt with in the Cycad Action Plan have been badly affected by habitat destruction and plant collecting within the last century. As a result, more than half the known species are now classified as threatened, and the cycads stand out as one of the most threatened groups of plants in this world.The Action Plan provides an overview of all the cycads and the threats to their survival. This is followed by separate assessments for the four broad regions where cycads now occur, namely Africa and the Indian Ocean Islands, Australia, Asia, and the New World. Trade in cycads has had a substantial impact on wild cycad populations and there is a separate chapter on trade and the effectiveness of control measures such as CITES. In addition, with so many species facing extinction in the wild, garden collections have become increasingly important and we have assessed the global status of cycad collections.Finally, the Cycad Action Plan presents a set of objectives and actions to reduce the threat to cycads in the wild and to provide ex situ conservation for those that almost certainly will become extinct in the wild. Wherever possible, we have tried to identify and build on innovative projects, such as community-based nurseries, and to link cycad consideration with other global and local initiatives such as the conservation of biodiversity hotspots.
