Book Description
Drawing on extensive ethnographic research, Anita Carrasco examines the socio-environmental impacts of contemporary mining on the Atacameños, an indigenous community in northern Chile, and their home in the Atacama Desert, one of the driest regions in the world. Carrasco describes the impacts of short-term mining corporations like Anaconda Copper that arrived, destroyed, and departed, and explains the positive and negative memories of those left behind. Embracing the Anaconda: A Chronicle of Atacameño Life and Mining in the Andes is recommended for students and scholars of anthropology, sociology, environmental studies, race and ethnic studies, and Latin American studies.

Book Description
Exploring the potential for extraterrestrial life and the origins of our own planet, this comprehensive introduction to astrobiology is updated with the latest findings. Informed by the discoveries and analyses of extrasolar planets and the findings from recent robotic missions across the solar system, scientists are rapidly replacing centuries of speculation about potential extraterrestrial habitats with real knowledge about the possibility of life outside our own biosphere—if it exists, and, if so, where. Casting new light on the biggest questions there are—how did we get here, and who else might be out there?—this third edition of Kevin W. Plaxco and Michael Gross's widely acclaimed Astrobiology incorporates a decade's worth of new developments in space to bring readers the most comprehensive, up-to-date, and engaging introduction to the field available. Plaxco and Gross examine the factors that make our Universe habitable, from the origin of chemical elements and the formation of the first galaxies and stars to the birth and composition of the planets. They describe the latest thinking about the origins of life, explain the evolution of metabolism and the development of complex organisms. In order to assess the limits for life elsewhere, they also explore life in extreme habitats and reveal how it informs the search for potential extraterrestrial habitats—ones that might support extraterrestrial life. New and updated illustrations enhance the book throughout. Sharing fascinating findings from the comet mission Dawn, the visit of New Horizons to Pluto, and the work of the Deep Carbon Observatory, which has revealed an incredible underground biosphere within our own planet, Plaxco and Gross weave together cosmology, astrophysics, geology, biochemistry, biophysics, and microbiology. From neutron star mergers to the survival skills of tardigrades, this fascinating book is an ideal primer for students or anyone curious about life and the Universe.

Book Description
The Central Andean Altiplane represents a unique extreme environment due to its high altitude, closed basins that modulate the salt pans and saline wetlands surrounded by deserts, as well as the considerable influence of volcanic activity. UV radiation, arsenic content, high salinity, alkalinity and low dissolved oxygen levels, together with extreme daily temperature fluctuations and oligotrophic conditions, shape an environment that resembles the early Earth and, even more, extraterrestrial conditions. By developing simple biofilms stratified microbial mats or complex microbialites, extreme microbial ecosystems, colonize and thrived in different environments like salt flats, wetlands, lakes volcano vents, geysers and deserts. This book presents our current understanding of these amazing ecosystems, providing a basis for their protection and sustainable utilization. The main audience for this book included researchers and graduate students as well as professionals working in the government, mining industry and similar activities.

Book Description
Water is usually referred to as the ‘Molecule of Life’. It constitutes the most abundant molecule in living (micro)organisms and is also essential for critical biochemical reactions, both for the global functioning and maintenance of Ecosystems (e.g., Photosynthesis) and individual (microbial) cells (e.g., ATP hydrolysis). However, most of Earth’s terrestrial environments present deficiencies in bioavailable water. Arid environments cover around a third of the land’s surface, are found on the six continents and, with the anthropogenic desertification phenomenon, will increase. Commonly defined by having a ratio of precipitation to potential evapotranspiration (P/PET) below 1, arid environments, being either hot or cold, are characterized by scant and erratic plant growth and low densities in macro-fauna. Consequently, these ecosystems are microbially mediated with microbial communities particularly driving the essential Na and C biogeochemical cycles. Due to the relatively simple trophic structure of these biomes, arid terrestrial environments have subsequently been used as ideal ecosystems to capture and model interactions in edaphic microbial communities. To date, we have been able to demonstrate that edaphic microorganisms (i.e., Fungi, Bacteria, Archaea, and Viruses) in arid environments are abundant, highly diverse, different from those of other terrestrial systems (both in terms of diversity and function), and are important for the stability and productivity of these ecosystems. Moreover, arid terrestrial systems are generally considered Mars-like environments. Thus, they have been the favored destination for astro(micro)biologists aiming to better understand life’s potential distribution and adaptation strategies in the Universe and develop terraforming approaches. Altogether, these points demonstrate the importance of significantly improving our knowledge in the microbial community composition (particularly for Fungi, Archaea and Viruses), assembly processes and functional potentials of arid terrestrial systems, as well as their adaptation mechanisms to aridity (and generally to various other environmental stresses). This Research Topic was proposed to provide further insights on the microbial ecology of hot and cold arid edaphic systems. We provide a detailed review and nine research articles, spanning hot and cold deserts, edaphic, rhizospheric, BSC and endolithic environments as well as culture-dependent and -independant approaches.

Book Description
Encyclopedia of Deserts represents a milestone: it is the first comprehensive reference to the first comprehensive reference to deserts and semideserts of the world. Approximately seven hundred entries treat subjects ranging from desert survival to the way deserts are formed. Topics include biology (birds, mammals, reptiles, amphibians, fishes, invertebrates, plants, bacteria, physiology, evolution), geography, climatology, geology, hydrology, anthropology, and history. The thirty-seven contributors, including volume editor Michael A. Mares, have had extensive careers in deserts research, encompassing all of the world’s arid and semiarid regions. The Encyclopedia opens with a subject list by topic, an organizational guide that helps the reader grasp interrelationships and complexities in desert systems. Each entry concludes with cross-references to other entries in the volume, inviting the reader to embark on a personal expedition into fascinating, previously unknown terrain. In addition a list of important readings facilitates in-depth study of each topic. An exhaustive index permits quick access to places, topics, and taxonomic listings of all plants and animals discussed. More than one hundred photographs, drawings, and maps enhance our appreciation of the remarkable life, landforms, history, and challenges of the world’s arid land.

Book Description
From Habitability to Life on Mars explores the current state of knowledge and questions on the past habitability of Mars and the role that rapid environmental changes may have played in the ability of prebiotic chemistry to transition to life. It investigates the role that such changes may have played in the preservation of biosignatures in the geological record and what this means for exploration strategies. Throughout the book, the authors show how the investigation of terrestrial analogs to early Martian habitats under various climates and environmental extremes provide critical clues to understand where, what and how to search for biosignatures on Mars. The authors present an introduction to the newest developments and state-of-the-art remote and in situ detection strategies and technologies that are being currently developed to support the upcoming ExoMars and Mars 2020 missions. They show how the current orbital and ground exploration is guiding the selection for future landing sites. Finally, the book concludes by discussing the critical question of the implications and ethics of finding life on Mars. Edited by the lead on a NASA project that searches for habitability and life on Mars leading to the Mars 2020 mission Presents the evidence, questions and answers we have today (including a summary of the current state of knowledge in advance of the ESA ExoMars and NASA Mars 2020 missions) Includes contributions from authors directly involved in past, current and upcoming Mars missions Provides key information as to how Mars rovers, such as ExoMars and Mars 2020, will address the search for life on Mars with their instrumentation
