Ecotones are dynamic over-lapping boundary areas where major terrestrial biomes meet. As past studies have shown, and as the chapters in this book will illustrate, their structure, size, and scope have changed considerably over the millennia, expanding and shrinking as climate and/or other driving conditions, also changed. Today, however, many of them are changing at a rate not seen for a long time, perhaps largely due to climate change and other human-induced factors. Indeed ecotones are more sensitive to climate change than the biomes on either side, and thus may serve as critical early indicators of future climate change. As ecotones change, they also redefine the limits of the biomes on either side by altering their distributions of species because, in addition to their own endemic species, any ecotone will also have species from both adjoining biomes. Consequently, they may also be places of high levels of species interaction, serving as active evolutionary laboratories, which generate new species that then migrate back into adjacent biomes. Ecotones Between Forest and Grassland explores how these ecotones have changed in the past, how they are changing today, and how they are likely to change in the future. The book includes chapters from around the world with a special focus on South American and Neotropical ecotones.

We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Philosophers, writers and scientists, from cell biologists to ecologists, have long recognized the special nature of boundaries and interface areas of all kinds. Among ecologists in particular, there has been an upsurge in interest in the sensitive boundary areas of interaction between ecosystems, which are called 'ecotones' and which are often characterized by higher biological diversity than adjacent areas.

In this book, Krall proposes a counter-narrative to the usual reading of marginality. In autobiographical narrative that rings with experience, she describes margins as rich and dynamic abodes, places of crossing over and transition as well as spaces of separation and alienation. In reinterpreting journeys and encounters, she maps the shared terrain of the personal, natural, and social fields of our lives.

Ecotones, or boundary zones between land and inland waters (such as lakes, streams and rivers), are the principal routes for transport of organic matter and nutrients across landscapes via physical and biological vectors. The ecotone is the place of cumulation and transformation of in situ production as well as of allochthonous material from adjacent aquatic and terrestrial systems. The ecotype functions as an important barrier or filter for principal nutrients, such as phosphorus and nitrogen, responsible for the eutrophication and degradation of surface waters. Intensive forest cutting, agriculture, pollution and bank regulation, urbanization and hydrotechnical constructions seriously endanger the ecotone systems and damage their protective function. It is vital to develop a scientific understanding of the behaviour of phosphorus and nitrogen in these transitional boundary habitats. Such an understanding is important for the rational protection, management and restoration of ecotones connected with lakes and rivers. The importance of nutrient cycling and retention is discussed from the point of view of ecotone function, management and reconstruction in order to sustain its protective role for water bodies. Various types of land/water transitory zones are discussed: wetlands, lake littoral systems, riparian zones of rivers, streams and brooks, the contact zones between groundwater and surface waters of lakes and rivers, air--water interfaces, and patch/ecotone structures in watersheds.

Ecotones are interface zones between different ecosystems. Their ecological role and significance with regard to ecological management and conservation has become increasingly appreciated. For the management of freshwater resources, for example, an improved understanding of the role of land/inland water interfaces, will be essential for reducing negative human impacts by engineering, nutrient loading, siltation, etc. The management of ecotones, on the other hand, offers the possibility to control aquatic system processes via stock control of fish populations. Fish apparently are both excellent indicators of ecotone quality as well as determiners of its structure and function.

This book brings together comprehensive multi-disciplinary knowledge on diverse aspects of the Himalayan treeline ecotone which is considered one of the most sensitive ecosystems to climate change. The contents of this book are based on the results of extensive research and provide a holistic understanding of the treeline ecotone in Himalaya. The book will serve as an important reference manual and a textbook on treeline ecology. The book is unique in the sense that it provides an engaging account of almost all the aspects of the treeline ecotone, such as taxonomic, functional and phylogenetic species diversity, temperature lapse rates, tree phenology, water relations, and stress physiology, tree ring width chronology, and climate relationships and the role of treeline ecotone in human sustenance in the Indian Himalayan region The treelines in the Himalaya, being the highest in the Northern Hemisphere (up to 4900 m), are among the least investigated systems and hence this book is timely and fills all-important knowledge gaps vis-à-vis treeline shifts, physiognomic, structural, and functional changes in mountain landscapes and ecosystems, particularly under the changing climate This book, for the first time, summarizes evidence-based knowledge about various aspects of treeline ecotone in Himalaya that was largely generated through a well-coordinated a team science approach. The book will be of interest to ecologists, climatologists, dendrochronologists, foresters, plant physiologists and resource managers and policy planners for a better understanding of the organization and dynamics of this fragile ecosystem in relation to climate change and other anthropogenic stresses that are rampant in the Himalaya. The book lays a solid foundation for further investigation of the ecology and dynamics of the treeline ecotone in the Himalayas and provides a rationale for pursuing a team science approach for macroecological investigations.
