Book Description
This is the ninth volume of papers in the Journal of Practical Ecology & Conservation series. There is a range of topics covered in this issue from monitoring upland vegetation to the ecology of the New Zealand Walking Bat and the case for using wood-fuel as a means of sustainably managing moorlands and heaths. The editorial paper looks at grazing regimes and the impact of cultural severance on managing wooded landscapes.

Book Description
Termites are eusocial insects that live in colonies composed of hundreds to millions of individuals. Their colonies are mainly organized into reproductive and non-reproductive castes, which have specific tasks such as nest construction, foraging, reproduction, brood care, and colony defense. The evolution of the symbiotic association between termites and microorganisms allows them to decompose ingested lignocellulose from plant substrates (such as wood), including herbivore dung and soil humus, making them important insect decomposers that play a crucial role in ecosystem functioning by contributing to litter decomposition, soil formation, and nutrient cycling. On the other hand, termites have recently been classified as eusocial cockroaches, which have gained increasing attention in evolutionary studies to understand the transition to eusociality from subsocial wood roaches. This current growing interest in termite research calls for a collection dedicated to these fascinating insects.

Book Description
Elastomeric Nanocellulose Composites provides an in-depth study of recent developments in this fast-evolving research field. This book covers diverse aspects of materials engineering, surface treatments, and fabrication of green nanocomposites. It consolidates recent studies and qualitative findings on the incorporation of a myriad of nanocellulose variants into various types of elastomer matrices with the main goal of enhancing its mechanical integrity and potentially phasing out conventional elastomer fillers. The current market is likewise discussed in detail. This book will provide an in-depth study of current developments of nanocellulose incorporated elastomer composites and their applications.The book will be an essential reference resource for material scientists, academic and industrial researchers, and technologists covering all aspects in the field. Carbon black and silica are currently used as fillers in elastomer-based composites, but the use of these reinforcing agents is not sustainable or eco-friendly. Therefore there is a need to look for more sustainable filler materials for elastomers. - Assists readers in solving fundamental and application-related problems in the development of nanocellulose filled elastomers - Discusses characterization techniques used for analyzing elastomer nanocomposites - Provides various attributes of nanocellulose, its composites with different types of elastomeric materials (both natural and synthetic) and its potential for advanced applications - Includes comprehensive, well structured content to maintain consistency and flow to help readers easily navigate chapters

Book Description
Visual Research: A Concise Introduction to Thinking Visually is the first text to present a concise overview of the significant ethical, theoretical, and practical considerations for conducting research with images. The capacity to take photos and video on handheld devices and the ability to store, post, and share such imagery online all offer tremendous opportunities for social research. The rapid development and popularity of such technology means that little technological proficiency is required, and even less theoretical and ethical consideration. This book provides an accessible introduction to doing visual research in the social sciences. Beginning with ethical considerations, this book highlights the importance of thinking visually before engaging in visual research. Further themes involve creating, organizing, and using images and are presented so as to help readers think about and work with their own visual data. Boxed case studies and further reading suggestions enhance the utility of this primer. Concise and highly focused, Visual Research will be an invaluable resource for visual, media, and communications students and researchers and others interested in visual research in the social sciences.

Book Description
Daniel J. C. Kronauer brings to life the research surrounding army ants, nature's preeminent social hunters. Without central coordination, army ants march in columns by the thousands and build nests and bridges using their own bodies. They also play a crucial role in promoting and sustaining the biodiversity of tropical ecosystems.

Book Description
This book is devoted to the alkaline-saline lakes of East Africa, which include the world-famous “flamingo lakes”. It covers the full range of issues, from the lakes’ origin and history, life in and around these unique water bodies, to utilization, threats and management considerations. The authors, all of whom are leading international experts, summarize research done so far, highlight new and important findings, and provide future outlooks. The book is divided into three main sections: “Genesis, physics and chemistry” tackles lake development and the astounding physico-chemistry of the lakes. “Organisms and ecology” presents information about the many lake inhabitants, their interactions and adaptations to the extreme living conditions. “Utilization, management and perspectives” addresses threats such as lake exploitation and pollution, but also considers potential uses. This book will be particularly relevant to researchers and lecturers in the field of limnology and aquatic ecology, but is also designed to attract all those interested in nature and life on our planet.

Book Description
How did human beings acquire imaginations that can conjure up untrue possibilities? How did the Universe become self-aware? In The Runes of Evolution, Simon Conway Morris revitalizes the study of evolution from the perspective of convergence, providing us with compelling new evidence to support the mounting scientific view that the history of life is far more predictable than once thought. A leading evolutionary biologist at the University of Cambridge, Conway Morris came into international prominence for his work on the Cambrian explosion (especially fossils of the Burgess Shale) and evolutionary convergence, which is the process whereby organisms not closely related (not monophyletic), independently evolve similar traits as a result of having to adapt to similar environments or ecological niches. In The Runes of Evolution, he illustrates how the ubiquity of convergence hints at an underlying framework whereby many outcomes, not least brains and intelligence, are virtually guaranteed on any Earth-like planet. Conway Morris also emphasizes how much of the complexity of advanced biological systems is inherent in microbial forms. By casting a wider net, The Runes of Evolution explores many neglected evolutionary questions. Some are remarkably general. Why, for example, are convergences such as parasitism, carnivory, and nitrogen fixation in plants concentrated in particular taxonomic hot spots? Why do certain groups have a particular propensity to evolve toward particular states? Some questions lead to unexpected evolutionary insights: If bees sleep (as they do), do they dream? Why is that insect copulating with an orchid? Why have sponges evolved a system of fiber optics? What do mantis shrimps and submarines have in common? If dinosaurs had not gone extinct what would have happened next? Will a saber-toothed cat ever re-evolve? Cona Morris observes: “Even amongst the mammals, let alone the entire tree of life, humans represent one minute twig of a vast (and largely fossilized) arborescence. Every living species is a linear descendant of an immense string of now-vanished ancestors, but evolution itself is the very reverse of linear. Rather it is endlessly exploratory, probing the vast spaces of biological hyperspace. Indeed this book is a celebration of how our world is (and was) populated by a riot of forms, a coruscating tapestry of life.” The Runes of Evolution is the most definitive synthesis of evolutionary convergence to be published to date.
