Nannochoristidae (=Nannomecoptera) and Boreidae (=Neomecoptera) are traditionally assigned to the holometabolan Order Mecoptera. Both are presently in the focus of insect systematists. They differ strikingly from the "typical" mecopteran pattern, not only in their larval and adult morphology, but also in their life style and reproductive biology. Phylogenetic affinities between Boreidae ("snow fleas") and fleas were postulated mainly based on molecular data, and morphological characters related to food uptake and larval features suggest a close relationship between Nannochoristidae and true flies. Both groups display fascinating features such as preferred temperatures around 0°C, extremely slender larvae adapted to running water, and a highly unusual mating behaviour. Despite of the extremely low number of known species, there is no doubt that both groups are key taxa and in their own way highlights in the evolution of the extremely successful Holometabola. This and an impressive number of recent studies on various aspects of Nannochoristidae and Boreidae more than justifies a new volume in the series Handbook of Zoology dedicated to these highly unusual taxa.
This book explores the life and work of Mary Elizabeth Barber, a British-born settler scientist who lived in the Cape during the nineteenth century. It provides a lens into a range of subjects within the history of knowledge and science, gender and social history, postcolonial, critical heritage and archival studies. The book examines the international importance of the life and works of a marginalized scientist, the instrumentalisation of science to settlers' political concerns and reveals the pivotal but largely silenced contribution of indigenous African experts. Including a variety of material, visual and textual sources, this study explores how these artefacts are archived and displayed in museums and critically analyses their content and silences. The book traces Barber’s legacy across three continents in collections and archives, offering insights into the politics of memory and history-making. At the same time, it forges a nuanced argument, incorporating study of the North and South, the history of science and social history, and the past and the present.
