Book Description
The Erpodiaceae (Bryophyta) is a family of very small to small, pleurocarpous mosses most closely related to the Orthotrichaceae. Mosses in the Erpodiaceae are found mainly in drier areas of the tropical and subtropical regions of the world. Five genera are recognized in this study--Aulacopilum (2 species, 3 subspecies), Erpodium (2 species), Solmsiella (2 species), Tricherpodium (1 species, 2 subspecies), and Venturiella (8 species, 7 subspecies). This study is primarily morphologically based. The genera and species within each genus are arranged alphabetically. Keys are provided to the genera, sections, species, and subspecies. All genera, sections, species, and subspecies are described; illustrations and distribution maps are provided for each species and subspecies. The book includes twenty nomenclatural novelties.

Book Description
This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.

Book Description
Lichen assocIations include some of the oldest living organisms and represent a major nutritional method adopted by one in five fungi. Major advances in our knowledge of these biologically fascinating organisms have been made in recent years and they now have a great deal to offer to teaching in colleges and universities. In addition to being examples of biotrophic systems, they merit discussion in courses on fungal phylogeny, fungal nutrition, ecology, ecophysiology, biogeography, evolution, chemo taxonomy, environmental monitoring, and algology. As all aspects of lichenology cannot be treated adequately in a book of this length, we have emphasized topics which we have found to be of particular interest to a advanced undergraduate and postgraduate biologists (or biogeographers) or those contemplating more detailed studies in particular areas. Consequently we have endeavoured to place lichen associations in the broader context of biological and biogeographical teaching. Examples are drawn from many areas of the world, including North America, but it is inevitable that European ones predominate, as lichens there are better known than in other regions. Technical terms are defined when first used, and definitions can therefore be located with the aid of the index. Lichens are not a systematic group and so are not appropriately treated in a groups-orientated programme, but are a major biological phenomenon all too commonly accorded scant attention in university courses.

Book Description
This issue of Journal of Insect Conservation is the first to be dedicated entirely to beetles. It contains a number of papers to demonstrate the variety and scope of problems and conservation concerns that surround these insects. A short introductory perspective is followed by eight original contributions, in which beetles from many parts of the world are considered, and in which some major threats to their wellbeing are evaluated.

Book Description
Forest canopies not only support high terrestrial biodiversity but also represent a critical interface between the atmosphere and the earth. They provide goods and services to support diverse human communities and offer opportunities to explore sustainable use of these resources for many generations of local livelihoods. Forest canopies are important carbon sequestration units, and in this sense, serve as climate control for the planet. Canopies are important energy production centers for the planet, and serve as the basis for many food chains. The canopy can also act as a hook for education outreach and conservation, inspiring ecotourism through recreation and other sustainable uses such as treetop walks, zip lines, and birding. Despite these critical services provided by forest canopies, almost no dedicated research in the treetops was initiated until as recently as the late 1970s when single rope techniques were developed by mountaineering professionals and adapted for use in the canopy. Subsequently, an array of canopy access tools was designed in the 1980s and early 1990s that have opened up this “eighth continent” for global exploration and discovery. This volume uses the major findings of the 5th international canopy conference as a platform for organization, but it does not mimic the sessions and presentations of the conference itself. Instead, it builds on the important themes that emerged from the conference and solicits articles that represent future priorities and advancements for canopy science in the next decade. Despite the global efforts of hundreds of forest scientists over the past 3 decades, forests are degrading at an accelerated rate and biodiversity is increasingly threatened by human activities. Given these trends - despite the very best efforts of the world’s best scientists - other approaches must be taken. This volume summarizes the issue of “treetops at risk” and assembles a global authorship to examine past accomplishments and future initiatives critical in forest conservation.
