Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).
The fishing technology of the Classical world has so far received little systematic attention, neither from historians nor from archaeologists. In this volume, the reader will find a series of studies offering a wide range of approaches to the topic of ancient fishing technology, based on detailed studies of the available literary, archaeological, pictorial and icthyological evidence as well as on diachronic comparisons with fishing techniques of the Early Medieval and Modern periods. The articles included in the present volume are based on the authors' presentations at an international, interdisciplinary workshop in Cadiz, covering the history of fishing from Pre-history to the present day, with a special emphasis on the Roman period.
The first section reviews trends of bean production and constraints in Latin America and Africa. The second section covers fungal diseases. The third section, bacterial diseases. The fourth section, viral and mycoplasma diseases. The fifth section, insect pests. The last section, other bean production constraints, that is, nutritional disorders, nematodes, seed pathology, and additional problems.
This book takes readers back and forth through time and makes the past accessible to all families, students and the general reader and is an unprecedented collection of a list of events in chronological order and a wealth of informative knowledge about the rise and fall of empires, major scientific breakthroughs, groundbreaking inventions, and monumental moments about everything that has ever happened.
This volume challenges the orthodox view that fishing and fish played only a marginal role in the economy of the ancient world. In fact, there is archaeological evidence for ancient fish processing on a commercial scale not only in the Mediterranean itself, but also on the Atlantic coast and in the Black Sea region, especially the Crimea. Our literary sources testify to the widespread culinary and medicinal use of salted fish and fermented fish sauces in antiquity, and especially in the first centuries AD. In this book, the authors assess the present state of research on ancient fishing and discuss its implications for the history of the Black Sea region, especially the period of Greek colonization along its shores. While grain has traditionally been viewed as the main export commodity of the Pontic colonies, the existence of salting-vats on the coast of the Crimea indicate production of salt-fish or fish sauce on a large scale, presumably for export. However, many questions remain unanswered: for instance concerning ownership and organization of the processing facilities, or how the finished product was transported to distant markets. Tonnes Bekker-Nielsen teaches ancient history at the University of Southern Denmark, Esbjerg.
Drawing Futures brings together international designers and artists for speculations in contemporary drawing for art and architecture.Despite numerous developments in technological manufacture and computational design that provide new grounds for designers, the act of drawing still plays a central role as a vehicle for speculation. There is a rich and long history of drawing tied to innovations in technology as well as to revolutions in our philosophical understanding of the world. In reflection of a society now underpinned by computational networks and interfaces allowing hitherto unprecedented views of the world, the changing status of the drawing and its representation as a political act demands a platform for reflection and innovation. Drawing Futures will present a compendium of projects, writings and interviews that critically reassess the act of drawing and where its future may lie.Drawing Futures focuses on the discussion of how the field of drawing may expand synchronously alongside technological and computational developments. The book coincides with an international conference of the same name, taking place at The Bartlett School of Architecture, UCL, in November 2016. Bringing together practitioners from many creative fields, the book discusses how drawing is changing in relation to new technologies for the production and dissemination of ideas.
A pan-European overview of the archaeology of hunter-gatherer societies, written by experts in each region.
