Book Description
This manual provides illustrated keys to all leaf and scale lichens known to occur in British Columbia. In total, 327 species are included, while 19 taxa are excluded from earlier accounts of the flora. Accompanying the keys are approximately 350 line drawings. The manual briefly summarizes the ecology, distribution, and frequency status of the province's foliose and squamulose lichens. Each genus account provides a common name, a short description, pertinent references, notes on the derivation of the common name, and notes on global status and distribution, taxonomy, chemistry, and/or similar genera. Each species account provides species and author citation, distribution maps, common names, habit, and lichen distribution in B.C.

Book Description
Accountability of government to citizens is the foundation for good governance. Unfortunately, many developing countries suffer the results of dysfunctional governance systems that fail to provide even minimal levels of vital public services. The key message of the New Institutional Economics is that incentives matter. In the public sphere, the countries' accountability frameworks rewards, sanctions, and measurement of performance shape public sector performance. This book applies this fundamental insight to fiscal/budgetary analysis and public service delivery, giving the reader tools and around the globe examples of institutional arrangements that help citizens hold government accountable for their performance.

Book Description
Each time history repeats itself, so it's said, the price goes up. The twentieth century was a time of runaway growth in human population, consumption, and technology, placing a colossal load on all natural systems, especially earth, air, and water — the very elements of life. The most urgent questions of the twenty-first century are: where will this growth lead? can it be consolidated or sustained? and what kind of world is our present bequeathing to our future?In his #1 bestseller A Short History of Progress Ronald Wright argues that our modern predicament is as old as civilization, a 10,000-year experiment we have participated in but seldom controlled. Only by understanding the patterns of triumph and disaster that humanity has repeated around the world since the Stone Age can we recognize the experiment's inherent dangers, and, with luck and wisdom, shape its outcome.

Book Description
A comprehensive, up-to-date review of lichens as biomonitors of air pollution (bioindication, metal and radionuclide accumulation, biomarkers), and as monitors of environmental change (including global climate change and biodiversity loss) in a wide array of terrestrial habitats. Several methods for using lichens as biomonitors are described in a special section of the book.

Book Description
This book consists of a collection of individual papers surveying the existing knowledge of biodiversity in British Columbia. The first section contains papers that consider the importance of an ecosystem-centred approach to the conservation of biodiversity, explain the methods of classifying the status of rare species, and review the role of biosystematics and taxonomy in the study of biodiversity. The second section focuses on the diversity of species in British Columbia, with papers on specific species or groups such as lepidoptera, marine invertebrates, lichens, bryophytes, fish, fungi, mammals, birds, reptiles, and vascular plants. Part three summarises information on the diversity of the province's ecosystems, with papers on such topics as forests, grasslands, marine areas, urban areas, and atmospheric change. The final section discusses ways of protecting biodiversity, concluding with a summary of recommendations for biodiversity conservation.

Book Description
Nephroma occultum (Cryptic Modest Lichen) is a member of the Nephromataceae (or Peltigeraceae) known to occur in Canada only in the humid, primarily old growth forests of British Columbia. It is a rounded, loosely appressed, foliose (leaf) lichen. This report provides species information such as description, biological and economic significance, distribution, environment and habitat characteristics, population biology, population ecology, land ownership and management responsibility, management practices and experience, evidence of threats to survival, and legal or other formal status. It goes on to offer an assessment of the status for the species and information sources.

Book Description
This new edition of Fungi in Ecosystem Processes continues the unique approach of examining the roles of fungi from the perspective of ecosystem functions. It explores how fungi have adapted to survive within particular constraints, how they help to maintain homeostasis in ecosystems, how they facilitate resistance to perturbations, and how they influence the communities of other organisms. Updated and revised, the second edition Expands the section on plant pathogens, invasive species, and insect–fungal interactions Provides more extensive coverage on insect–fungal interactions, including entomopathogens, the links between entomopathogens and endophytes, and symbiotic and mutualistic interactions Adds a new section on fungi in the built environment Presents new material on below-ground to above-ground interactions mediated through fungi, such as mycorrhizal signaling systems for herbivory defense The book also includes expanded coverage of the role of fungi in suppressive soils, aquatic and marine fungi, modern methods of following food chains in fungal–invertebrate trophic interactions, and the physiology of nutrient uptake by mycorrhizae. A necessary update and expansion to previous material, this book provides an essential reference on the current understanding of fungal roles in ecosystem processes. It also identifies directions for future study, including an emphasis on the need for further research on fungi in built environments.
