Book Description
A great fascination for biologists, the study of embryo development provides indispensable information concerning the origins of the various forms and structures that make up an organism, and our ever-increasing knowledge gained through the study of plant embryology promises to lead to the development of numerous useful applications. In Plant Embryo Culture: Methods and Protocols, expert researchers from the field provide a ready source of information for culturing zygotic embryos for different types of studies, both theoretical and practical. The book’s main sections examine a wide range of related topics, including the culture of zygotic embryos for developmental studies, the application of embryo culture techniques focusing on embryo rescue methods, cryopreservation of zygotic embryos, the use of zygotic embryos as explants for somatic embryogenesis and organogenesis, as well as transformation protocols using zygotic embryos as starting material. Written in the highly successful Methods in Molecular BiologyTM series format, the detailed chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and vital notes on troubleshooting and avoiding known pitfalls. Authoritative and convenient, Plant Embryo Culture: Methods and Protocols serves as a key reference that can be used by scientists of all backgrounds to help develop their own customized methods for many different species and for a variety of purposes.

Book Description
Become a better crisis leader while equipping yourself with the tools for every day transformative leadership Today, in an instant, leaders can find themselves face-to-face with crisis. An active shooter. A media controversy. A data breach. In You're It, the faculty of the National Preparedness Leadership Initiative at Harvard University takes you to the front lines of some of the toughest decisions facing our nation's leaders-from how to mobilize during a hurricane or in the aftermath of a bombing to halting a raging pandemic. They also take readers through the tough decision-making inside the world's largest companies, hottest startups, and leading nonprofits. The authors introduce readers to the pragmatic model and methods of Meta-Leadership. They show you how to understand what is happening during a moment of crisis and change, what to do about it, and how to hone these skills to lead high-performing teams. Then, when crisis hits, you can pivot to be the leader people follow when it matters most. A book for turbulent times, You're It is essential reading for anyone preparing to lead an adaptive team through crisis and change.

Book Description
The Ancient Human Occupation of Britain Project (AHOB) funded by the Leverhulme Trust began in 2001 and brought together researchers from a range of disciplines with the aim of investigating the record of human presence in Britain from the earliest occupation until the end of the last Ice Age, about 12,000 years ago. Study of changes in climate, landscape and biota over the last million years provides the environmental backdrop to understanding human presence and absence together with the development of new technologies. This book brings together the multidisciplinary work of the project. The chapters present the results of new fieldwork and research on old sites from museum collections using an array of new analytical techniques. - Features an up-to-date treatment of the record of human presence in the British Isles during the Palaeolithic period (700,000 - 10,000 years before present) - Takes multidisciplinary approach that includes archaeology, geochemistry, geochronology, stratigraphy and sedimentology - Coincides with the culmination of the AHOB project in 2010, providing a benchmark statement on the record of human occupation in Britain that can be utilized and tested by future research

ÿ This book is dedicated to the palaeontogical site of Kromdraai, one of the most well-known sites of the ?Cradle of Humankind?, the famous UNESCO World Heritage site located in the Gauteng province (South Africa). From 1938 to 1943, Robert Broom described important hominin fossil discoveries from Kromdraai as belonging to a single individual and designated the type specimen as one of our distant relatives, called Paranthropus robustus

Book Description
Somatic embryogenesis, the initiation of embryos from previously differentiated somatic cells, is a unique process in plants. This volume expands our view of a subject that is important for plant biotechnology, genetics, cell biology, development, and agricultural applications. All chapters present the latest research progress, including functional genomic, genetic, and proteomic approaches. A special focus is placed on the effects of stress, environment, and plant growth regulators on embryogenesis. The role of genes such as Leafy Cotyledons and Baby Boom in defining and maintaining cell competence is discussed.

Book Description
This is the final volume in the monograph series resulting from archaeological excavations in the Ebbsfleet Valley in advance of High Speed 1 and the Ebbsfleet International station. It provides the full account of the discovery, excavation and subsequent analysis of rich and deeply buried archaeological horizons found late in the construction programme, dating to early in the Palaeolithic and associated with the Hoxnian interglacial between about 425,000 and 375,000 years ago.The highlight of this work was recovery of the remains of an extinct straight-tusked elephant Palaeoloxodon antiquus surrounded by the undisturbed scatter of flint tools used for its butchery, made and abandoned at the spot. Rich fossil palaeo-environmental remains provide a remarkable record of the climate and environment, showing that the elephant lived and died at a time of peak interglacial warmth, when the Ebbsfleet Valley was a lush, densely-wooded tributary of the Thames, containing a quiet, almost stagnant swamp. The abundant lithic remains from the elephant horizon are attributable to the Clactonian industrial tradition, after Clacton-on-Sea, Essex where similar remains have been found. The evidence from this new site provides the best record yet of Clactonian remains from the Hoxnian, establishing that Britain was re-settled (after local extinction due to the great Anglian glaciation) by hominins who did not make handaxes, generally the typical artefact of the earlier Palaeolithic. The elephant horizon is overlain by a younger deposit rich in handaxes of various forms, including sharply pointed specimens, bluntly pointed sub-cordates and twisted ovates. Possible interpretations for this sequence of greatly contrasting lithic industries are discussed in the volume.Finally, this monograph provides a fascinating case-study of Palaeolithic excavation methods, and how archaeological work is carried out in conjunction with large engineering developments such as High Speed 1.

Book Description
Five years after returning from his trip around the world, young Charles Darwin became the owner of Down House in Kent, England, where he moved his growing family, far away from the turmoil and distractions of London. He would live there for the rest of his life, and it would become the place where he began work on his masterpiece, On the Origin of Species. For almost twenty years, he used the garden around him as a laboratory. In the orchard, he conducted experiments on pollination. He built a dovecote where breeding new strains of pigeons helped him understand the intricacies of generation. On his daily walk along the sandbank, he observed how plants competed for survival. In solitude he struggled with the ideas of evolution that had haunted him since his voyage, which, in turn, gave him the courage to publish his revolutionary ideas. Bringing Darwin's garden to the present day, Boulter unfolds a shining portrait of the formation of one of England's greatest thinkers and his relationship with the place he loved, and shows how his experiments—conducted more than 150 years ago—are still revealing new proofs as we continue to search for the origins of life.
