These proceedings of the 2018 XIII International Symposium on Spermatology focus on comparative biology, and encourages discussion and the exchange of ideas. The aim of this Symposium was to provide a unique opportunity and bring together scientists from a wide spectrum of research fields – human, domestic animals and other mammals, vertebrates, insects, and plants. The underlying focus is on the function of the spermatozoon – a common feature for sexual reproduction, but extremely varied. By exploring the variability, a better understanding of male reproductive functions can develop. These proceedings address the mechanisms of physiology and pathophysiology, rather than diagnosis and treatment. The symposium featured keynote lectures by invited speakers, followed by presentations on specific aspects of the general topic of the session. Experimental studies are given priority over clinical studies of patient populations. The proceedings comprise both keynote speakers' texts and selected free communications. Posters were considered for publication in the proceedings, and the volume includes exhibited materials on the work of prominent spermatologists, highlighting their important past achievements in the field.

This second edition emphasizes the environmental impact on reproduction, with updated chapters throughout as well as complete new chapters on species such as sharks and rays. This is a wide-ranging book that will be of relevance to anyone involved in species conservation, and provides critical perspectives on the real utility of current and emerging reproductive sciences. Understanding reproductive biology is centrally important to the way many of the world’s conservation problems should be tackled. Currently the extinction problem is huge, with up to 30% of the world’s fauna being expected to disappear in the next 50 years. Nevertheless, it has been estimated that the global population of animals in zoos encompasses 12,000 – 15,000 species, and we anticipate that every effort will be made to preserve these species for as long as possible, minimizing inbreeding effects and providing the best welfare standards available. Even if the reproductive biology community cannot solve the global biodiversity crisis for all wild species, we should do our best to maintain important captive populations. Reproductive biology in this context is much more than the development of techniques for helping with too little or too much breeding. While some of the relevant techniques are useful for individual species that society might target for a variety of reasons, whether nationalistic, cultural or practical, technical developments have to be backed up by thorough biological understanding of the background behind the problems.

One of the major questions in the evolution of animals is the transition from unicellular to multicellular organization, which resulted in the emergence of Metazoa through a hypothetical Urmetazoa. The Comparative Embryology of Sponges contains abundant original and literary data on comparative embryology and morphology of the Porifera (Sponges), a group of 'lower Metazoa'. On the basis of this material, original typization of the development of Sponges is given and the problems concerning origin and evolution of Porifera and their ontogenesis are discussed. A morphogenetic interpretation of the body plan development during embryogenesis, metamorphosis and asexual reproduction in Sponges is proposed. Special attention is given to the analysis of characteristic features of the ontogenesis in Porifera. The book pursues three primary goals: 1) generalization of all existing information on individual development of sponges, its classification and a statement according to taxonomical structure of Porifera; 2) revealing of heterogeneity of morphogenesis and peculiarities of ontogeneses in various clades of Porifera, and also their correlations with the organization, both adult sponges, and their larvae; 3) revealing homology of morphogeneses in both Porifera and Eumetazoa, testifying to the general evolutionary roots of multicellular animals, and peculiar features of sponges' morphogeneses and ontogenesis. This book will be of interest to embryologists, zoologists, morphologists and researchers in evolutionary biology.

Ascidians are the invertebrate group that gave rise to vertebrates, thus the biology of ascidians provides an essential key to understanding both invertebrates and vertebrates. This book is the first to cover all areas of ascidian biology, including development, evolution, biologically active substances, heavy metal accumulation, asexual reproduction, host-defense mechanisms, allorecognition mechanisms, comparative immunology, neuroscience, taxonomy, ecology, genome science, and food science. The 69 articles that make up the collection were contributed by leading ascidiologists from all over the world who participated in the First International Symposium on the Biology of Ascidians, held in June 2000 in Sapporo, Japan. For scientists and students alike, the book is an invaluable source of information from the latest, most comprehensive studies of ascidian biology.

In the compiling of this book, the vast literature dealing with the descriptive morphology, histology and cytology of teleost development has been combed and integrated. The book is divided into 21 chapters, starting with the egg and embryonic development up to hatching. This is followed by a description of ectodermal, mesodermal and entodermal derivatives and the development of various organs. The subject index, species index and the abundant illustrations add extra value to this long awaited book. Developmental Biology of Teleost Fishes will be a valuable tool for scientists and students in the fields of biology, developmental biology, molecular biology and fish biology.

During the Inaugural Meeting of the European Association of Acarol ogists (EURAAC), held in Amsterdam in 1987, it was decided that the holding of a Symposium at regular intervals should be a major objective. With this in view, it was agreed that Professor Reinhart Schuster, the senior editor, be invited to accept the Presidency of the Association and, arising from that Office, to organize the first Symposium in Austria in 1988. There was strong support for a main theme focused on a particular aspect of acarology. From these discussions there emerged the proposal that emphasis be placed on aspects of reproduction, development and life-history strategies of the Acari. These were topics in the forefront of the discipline with exciting developments of interest not only to acarologists but to a wider audience because of the light they cast on fundamental processes in physiology, ecology and evolutionary biology. The object then was to invite a small number of key workers to present extended papers related to the main theme. There were seven of these all of which appear in the book. The remaining 51 contributions were offered papers a number of which fit within the framework of the Symposium theme.
