In this Special Issue, we address the state of the art of the systematics of the main annelid groups and the improvements in the diversity they hold, with special emphasis on the latest discoveries in well-studied areas, expeditions to unsurveyed areas or environments, or the use of novel techniques that allow for the improvement of biodiversity knowledge. We are hoping that this Special Issue will provide a platform facilitating a review of current knowledge on the subject, identifying current research problems, as well as indicating directions and research trends for the future.

Recently, evidence has been accumulated which shows that some of the groups formerly regarded as independent "phyla" such as Pogonophora (now recognized as Siboglinidae), Echiura, Myzostomida and perhaps Sipuncula, are most probably nothing else than greatly modified Annelida. The extreme morphological diversity found especially in Polychaeta displays the plasticity of a simple segmented organisation that basically is nothing else but a serial repetition of identical units. Thus, annelids are highly important to our understanding of fundamental questions about morphological and adaptive diversity, as well as clarifying evolutionary changes and phylogenetic relationships. The book aims to summarize our knowledge on Polychaetes polychaetes and their allies and gives an overview of recent advances gained by studies that employed conventional and modern methods plus, increasingly and importantly, the use of molecular markers and computer-assisted kinship analyses. It also reflects the state of art in polychaete sciences and presents new questions and controversies. As such it will significantly influence the direction of research on Polychaeta and their related taxa.

Geomorphometry is the science of quantitative terrain characterization and analysis, and has traditionally focused on the investigation of terrestrial and planetary landscapes. However, applications of marine geomorphometry have now moved beyond the simple adoption of techniques developed for terrestrial studies, driven by the rise in the acquisition of high-resolution seafloor data and by the availability of user-friendly spatial analytical tools. Considering that the seafloor represents 71% of the surface of our planet, this is an important step towards understanding the Earth in its entirety.This volume is the first one dedicated to marine applications of geomorphometry. It showcases studies addressing the five steps of geomorphometry: sampling a surface (e.g., the seafloor), generating a Digital Terrain Model (DTM) from samples, preprocessing the DTM for subsequent analyses (e.g., correcting for errors and artifacts), deriving terrain attributes and/or extracting terrain features from the DTM, and using and explaining those terrain attributes and features in a given context. Throughout these studies, authors address a range of challenges and issues associated with applying geomorphometric techniques to the complex marine environment, including issues related to spatial scale, data quality, and linking seafloor topography with physical, geological, biological, and ecological processes. As marine geomorphometry becomes increasingly recognized as a sub-discipline of geomorphometry, this volume brings together a collection of research articles that reflect the types of studies that are helping to chart the course for the future of marine geomorphometry.

Britain’s shallow seas are a mysterious domain. They remain largely unseen and unexplored except by marine scientists and divers, who have been documenting their wondrous discoveries over many years. Now, a wealth of information about what lives on and in the seabed has been brought together in one sumptuously illustrated volume.Keith Hiscock describes the incredible variety of marine life that exists around Great Britain, providing a foundation of knowledge for those interested in the natural history of the shallow seabed. He explains how findings are gathered and organised, as well as showing what is out there and how it works. Fascinating, beautiful and often fragile, the habitats and marine life described are essential to the health and productivity of our oceans. Without an adequate, shared understanding of what and where they are, how can we identify and protect them?Exploring Britain’s Hidden World is the culmination of 50 years of research by the author to better understand where different subtidal seabed habitats occur and how their associated marine life has come to exist. That quest draws on a rich vein of knowledge obtained by many naturalists, scientists and divers who, for almost 200 years, have described seabed communities and sought to understand their structure and function.Using a minimum of technical terminology, Keith Hiscock combines his interests in marine biology, diving and photography to inform, inspire, and leave a vivid and lasting impression of the marine habitats and species around Britain. He hopes this book will provide new insights, much pleasure, and perhaps some surprises too.
