Annelids (the segmented worms) exist in a remarkably diverse range of mostly marine but also freshwater and terrestrial habitats, varying greatly in size and form. This text provides. This text begins with an introduction to the phylum and an outline of annelid taxonomy. The book describes their collection and the methods to ensure their optimal preservation, and provides an overview of anatomy with its relevant terminology. It includes the latest molecular phylogenomic evidence and is organised based on a new, robust phylogenetic hypothesis. It looks at groups which include Clitellata (comprising more than a third of total annelid diversity), Sipuncula, and Thalassematidae (formerly Echiura). It reflects the enormous amount of research on these organisms that has burgeoned since the millennium, principally due to their use as model organisms to address wider and more general evolutionary and ecological questions.
Polychaetes are very common marine worms belonging to the Annelid family that are of interest to marine biologists and invertebrate zoologists. The book presents an understanding of the biology of this group with many illustrations.
Here is a practical guide for anyone faced with organising a business. Because every organisation situation is unique, the reader should be familiar with a number of conceptual models and tools which can be of help when creating a theory for a particular situation. As consultants and businessmen, as well as through the elaboration of certain methods, the authors have developed a sense of what is important in the work of shaping or redesigning an organisation. This book will help anyone on the point of realizing a development in their organisation and wishing to know how this can effectively and successfully be accomplished.
Tracing the origins, evolution, and goals of Polish and Estonian émigré politics in Cold War Sweden and its linkages with both the host and homeland societies, this book investigates the transnational dimension of resistance and opposition to the communist regimes in Central and Eastern Europe. The analysis of the constantly shifting, at times conspiratorial, and even subversive networks that transcended the Iron Curtain draws a line from World War II to the collapse of the Soviet Union, framing half a century of transnationally concerted political activism in a geographical context that has not received much scholarly attention. Challenging the image of the Baltic Sea Region as a periphery of the European Cold War theater, the topography of the multilayered and complex linkages between neutral Sweden and her opposite coasts suggests that the small inland sea was a particularly vibrant setting for processes that efficiently defied the rigid border regimes of the Cold War era. This book relates both to ongoing historiographical debates about the scope and extent of East-West contacts that developed underneath the radar of international diplomacy and to the question of the role, significance, and impact of émigré politics during the Cold War. Embedding the dynamics of transnationally framed opposition in the wider context of political, economic, and cultural relations at the northeastern peripheries of divided Europe, the study not only sheds new light on so far still unexplored facets of interaction and cooperation between societies in East and West, but also offers a first comprehensive synthesis of the Baltic Sea Region’s post-war history.
