Now Available from CABI Illustrated keys are provided for the families, genera, species and other taxa of British and Irish Hydradephaga. The Hydradephaga comprise the Gyrinidae, Haliplidae, Noteridae, Paelobiidae (also known as Hygrobiidae) and the Dytiscidae. Colour plates are provided of all the species. Notes include characters for distinguishing the sexes, some basic information on biology and collecting methods, and reviews of distributions in Ireland and Britain, including the Channel Isles.

This second volume of Star Carr provides detail on specific areas of research around the Star Carr site, one of the most important Mesolithic sites in Europe. Discovered in the late 1940s by John Moore and then excavated by Grahame Clark from 1949-1951, the site is famous in the archaeological world for its wealth of rare organic remains including significant wooden artefacts. The 2003-2015 excavations directed by Conneller, Milner and Taylor explored how the site was used. In use for around 800 years, the Star Carr site is much larger and more complex than ever imagined. This volume looks in detail at focused areas of research, including: wooden artefacts; antler headdresses; structures; environmental and climate change data; plant and animal remains found at the site; and sediment data.

This volume assesses marsh-forts as a separate phenomenon within Iron Age society through an understanding of their landscape context and palaeoenvironmental development. These substantial monuments appear to have been deliberately constructed to control areas of marginal wetland and may have played an important role in the ritual landscape.

The first comprehensive book in more than a century to reveal the diversity and natural history of diving beetles. Among the hundreds of thousands of species of beetles, there is one family, containing some 4,300 species, that stands out as one of the most diverse and important groups of aquatic predatory insects. This is the Dytiscidae, whose species are commonly known as diving beetles. No comprehensive treatment of this group has been compiled in over 130 years, a period during which a great many changes in classification and a near quadrupling of known species has occurred. In Diving Beetles of the World, Kelly B. Miller and Johannes Bergsten provide the only full treatments of all 188 Dytiscid genera ever assembled. Entomologists, systematists, limnologists, ecologists, and others with an interest in aquatic systems or insect diversity will find these extensively illustrated keys and taxon accounts immensely helpful. The keys make it possible to identify all taxa from subfamily to genera, and each key and taxon treatment is accompanied by both photographs and detailed pen-and-ink drawings of diagnostic features. Every genus account covers body length, diagnostic characters, classification, species diversity, a review of known natural history, and world distribution. Each account is also accompanied by a range map and at least one high-resolution habitus image of a specimen. Diving beetles are fast becoming important models for aquatic ecology, world biogeography, population ecology, and animal sexual evolution and, with this book, the diversity of the group is finally accessible.

In the early Middle Ages, a network of maritime trading towns – emporia – emerged along the northern coasts of Europe. These early urban sites are among archaeology’s most notable contributions to our knowledge of the period between the disintegration of the Western Roman Empire and the growth of a maritime-oriented world in the Viking Age. Ribe, on the western coast of Denmark, is one of these sites. In 2017-18 the Northern Emporium research project conducted seminal research excavations, which provided new foundations for the study of this nodal point between Western Europe, Scandinavia, and the world beyond. This first volume presents the results of these excavations and analyses to piece together the history of the emporium and its social fabric. The research employs novel, high-definition methods to explore the networks of the site, integrating an extensive use of geoarchaeology and 3D stratigraphic recording with intensive environmental sampling and artefact recovery, resulting in more than 100,000 artefact finds. The results transform our understanding of key points of the early history of the North Sea region. Through the remains of dwellings and workshops – the traces left by traders, sailors, weavers, tailors, comb makers, and skilled producers of glass beads and metal ornaments – we follow the creation of Viking Age social networks, along with some of the most iconic artistic products of this world and the daily lives of some of its notable inhabitants.
