Book Description
Building the Most Complex Structure on Earth provides readers with a basic biological education an easy and understandable introduction into a new epigenetic theory of development and evolution. This is a novel theory that describes the epigenetic mechanisms of the development and evolution of animals and explains the colossal evolution and diversification of animals from a new post-genetic perspective. Modern biology has demonstrated the existence of a common genetic toolkit in the animal kingdom, but neither the number of genes nor the evolution of new genes is responsible for the development and evolution of animals. The failure to understand how the same genetic toolkit is used to produce millions of widely different animal forms remains a perplexing conundrum in modern biology. The novel theory shows that the development and evolution of the animal kingdom are functions of epigenetic mechanisms, which are the competent users of the genetic toolkit. Provides a comprehensive view of the epigenetic aspects of reproduction, development, and evolution. Highly rigorous, but simple enough for readers with only a basic knowledge of biology.

Book Description
Molecular Regulation of Endocytosis is a compilation of scientific "short stories" about the entry of external substances into cells. As one can see from the chapters, endocytosis regulates diverse processes such as homeostasis of the cell, signal transduction, entry of pathogens and viruses. In addition to the experimental techniques embedded in each chapter, entire chapters are dedicated to experimental approaches that will be useful to all scientists and their model systems. For those more clinically oriented, the final chapters look to the future and ways of utilizing endocytic pathways for therapeutic purposes.

Book Description
Evolutionary developmental biology or evo-devo is a field of biological research that compares the underlying mechanisms of developmental processes in different organisms to infer the ancestral condition of these processes and elucidate how they have evolved. It addresses questions about the developmental bases of evolutionary changes and evolution of developmental processes. The book’s content is divided into three parts, the first of which discusses the theoretical background of evo-devo. The second part highlights new and emerging model organisms in the evo-devo field, while the third and last part explores the evo-devo approach in a broad comparative context. To the best of our knowledge, no other book combines these three evo-devo aspects: theoretical considerations, a comprehensive list of emerging model species, and comparative analyses of developmental processes. Given its scope, the book will offer readers a new perspective on the natural diversity of processes at work in cells and during the development of various animal groups, and expand the horizons of seasoned and young researchers alike.

Book Description
The volume covers the preparation and analysis of model systems for biological electron microscopy. The volume has chapters about prokaryotic as well as eukaryotic systems that are used as so-called model organisms in modern cell biology. These systems include the most popular systems, such as budding and fission yeast, the roundworm C. elegans, the fly Drosophila, zebrafish, mouse, and Arabidopsis, but also organisms that are less frequently used in cell biology, such as Chlamydomonas, Dictyostelium, Trypanosoma, faltworms, Axolotl and others. In addition, tissues and tissue culture systems are also covered. These systems are used for very diverse areas of cell biology, such as cell division, abscission, intracellular transport, cytoskeletal organization, tissue regeneration and others. Moreover, this issue presents the currently most important methods for the preparation of biological specimens. This volume, however, is not a classic EM methods book. The methods are not the main focus of this issue. The main goal here is to cover the methods in the context of the specific requirements of specimen preparation for each model organism or systems. This will be the first compendium covering the various aspects of sample preparation of very diverse biological systems. Covers the preparation and analysis of model systems for biological electron microscopy Includes the most popular systems but also organisms that are less frequently used in cell biology Presents the currently most important methods for the preparation of biological specimens First compendium covering the various aspects of sample preparation of very diverse biological systems

Book Description
This book emphasises the important role that protozoa play in many natural ecosystems. To shed new light on their individual adaptive skills, the respective chapters examine the ecology and functional biology of this diverse group of eukaryotic microbes. Protozoa are well-established model organisms that exemplify many general problems in population ecology and community ecology, as well as evolutionary biology. Their particular characteristics, like large population sizes, life cycles and motile sensory behaviour, have a profound impact on their survival, distribution, and interaction with other species. Thus, readers will also be introduced to protozoan habitats in a broad range of environments. Even though this group of unicellular organisms is highly diverse, the authors focus on shared ecological patterns. Students and scientists working in the areas of eukaryotic microbiology and ecology will appreciate this updated and revised 2nd Edition as a valuable reference guide to the “lifestyles” of protozoa.
