This book examines the effectiveness and consistency of EU democracy promotion in its Eastern neighbourhood between 1991 and 2014. It concludes that the EU’s democratization role in this region was, not surprisingly, weak within this time period. However, this weak role only took shape under four domestic and transnational conditions: (a) a higher cost-benefit balance of rule transfer, (b) a lower structural difficulty a given country would need to overcome on its way towards a democratic regime, (c) increased levels of authority distribution across branches of power, and (d) a higher extent of democratic diffusion resulting from regional interactions. In those countries where these domestic and transnational conditions were present, as in Moldova, Ukraine, and Georgia, the EU’s democratizing influence was in causal terms only the tip of the iceberg. Most variation in regime dynamics remains to be explained by domestic and transnational contexts.

Root and tuber crops are important to agriculture, food security and income for 2.2 billion people in developing countries. These species produce large quantities of dietary energy and have stable yields under difficult environmental conditions. This second edition of Tropical Root and Tuber Crops is an authoritative treatment of four important root and tuber crops: cassava. sweet potato, yams, and aroids.
Since the concept of allelopathy was introduced almost 100 years ago, research has led to an understanding that plants are involved in complex communicative interactions. They use a battery of different signals that convey plant-relevant information within plant individuals as well as between plants of the same species or different species. The 13 chapters of this volume discuss all these topics from an ecological perspective. Communication between plants allows them to share physiological and ecological information relevant for their survival and ?tness. It is obvious that in these very early days of ecological plant communication research we are illuminating only the ‘tip of iceberg’ o...

This textbook provides a structured, easy to understand and thorough insight into the mode of function of plant secondary metabolites in plants and humans. It explains the biosynthesis and molecular action of nicotine, cannabis, caffeine and Co, describes the effects of these drugs on signal transduction at receptors and ion channels in animals, their relevance for human health and their potential for recreational use and abuse. It also offers a broad and comprehensive understanding on the role and function of these diverse molecules for the plants that make them. This textbook is written for master students and scientist in biochemistry and biology as well as for pharmaceutical and medical students. It will be a valuable study tool for teachers and students alike.
