From single-celled organisms in Black Sea sand to endemic cave crustaceans, from mountain glacial relict insects to the most diverse bird fauna in Europe, the fauna of Bulgaria has been a subject of study for more than a century. This is the first English language survey of all vertebrate and many key invertebrate groups of Bulgaria, their faunistics, origin, geographical and ecological distribution, and conservation issues.
European ecosystems and species remain under pressure from intensive agriculture and forestry, fishing, pollution, urban sprawl, invasive species and climate change. This book provides a detailed description and critical analysis of nature conservation responses, achievements and failures, motivated by the concerning state of nature and missed biodiversity targets. It summarises Europe's nature and the impact of human activities, and then gives an overview of relevant international biodiversity treaties and the EU nature conservation policy and legislative framework. The core of the book comprises chapters written by national experts, which cover the UK and twenty-five EU Member States, providing comparative case studies from which valuable lessons are drawn. Covering wide-ranging topics such as biodiversity pressures, legislation and governance, biodiversity strategies, species protection, protected areas, habitat management, and funding, this book is of interest to a wide audience, including academics and professionals involved in nature conservation and related environmental fields.
This is the first of two volumes on Gentianaceae. Comprising twelve chapters, it centres upon the characterization and ecology of Gentianaceae worldwide, with emphasis on the application of molecular and cytological approaches in relation to taxonomy. The first three chapters consider the classification of the family and review the advances in research since the earlier revision published in 2002, which resulted in the reclassification of some plants and the naming of new genera. The next chapter provides the most comprehensive report to date of the systematics of South American Neotropical woody Gentians. Other reviews include details of the Gentianaceae in Eastern Europe. The key biochemical steps that result in the diversity of Gentian flower colors, the cytology of European species and an historical account of the importance of Gentians in herbal medicines are also covered. Furthermore, an analysis of gene expression in overwintering buds is presented, discussing several aspects of plant taxonomy, phenotypic characteristics, phylogeography and pedigree. Two contributions highlight the importance of Gentians in India, and the last chapter presents evidence for the importance of Glomeromycota in developing arbuscular mycorrhizal associations with the roots of Gentians. This volume provides the basis for the biotechnological approaches that are considered in the companion book The Gentianaceae – Volume 2: Biotechnology and Applications.
This book is devoted to the Little Bustard, a medium sized Paleartic steppe bird whose distribution ranges from the Iberian Peninsula to Central Asia. At present, the European population is suffering a severe decline mainly due to agricultural intensification, although its status and concerns in non-European countries are relatively unknown. In spite of this dramatic situation, the Little Bustard is an interesting model species for topics as varied as phylogeny, life history evolution and demographic traits, sexual selection and lekking behavior, habitat selection, intra- and interspecific relationships, or interaction with farming and other anthropogenic disturbances. This book provides an updated, interdisciplinary, and worldwide review of the most recent information of this crucial species in the Palearctic steppe-bird community, from specific biological aspects and traits to research-focused management. Some of the most prominent scientists from different fields (systematics, breeding ecology, behavior, competence, predation, population dynamics, farming, conservation) update and synthesize the existing information on a singular, threatened and vulnerable species.

This book focuses on new and innovative spatial approaches based on smart solutions and developed in the field of geography and related interdisciplinary fields such as urban and regional studies, landscape ecology and ecosystem services. It includes contributions from a conference dedicated to the 100th anniversary of the Bulgarian Geographical Society. In turn, the book reveals how 21st-century geography is expected to facilitate the development of human capital and the knowledge society, while also offering place-specific solutions for sustainable regional development and utilization of the planet’s natural and human capital to improve social wellbeing. This volume is intended for the global geographical research community, as well as professionals and practitioners in all fields that deal with space, including regional planners and environmental managers.
