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
Martian surface contains diverse lithologies (from sedimentary rocks to mafic-ultramafic igneous rocks) and ground patterns. These rocks record the late-stage evolution on the Martian surface from a temperate environment with bodies of liquid water to the current cold and hyper-arid environment. The constraints on the key parameters and processes for water-rock interaction, sedimentation of materials, and geomorphological development can provide important insights into the environmental change and habitability on the Martian surface. However, due to the difficulty in accessing Martian samples and limited remote-sensing data available from the Martian surface, most of the mysteries on Mars remain unraveled. In this proposed research topic we will focus on geological settings on Earth that are similar to the conditions on Mars. These Mars analogs are employed to infer possible processes on Mars and their impact on habitability and the search for life. The Mars analogs on Earth span a variety of environments, such as the super-arid sedimentary plains (e.g., the Qaidam Basin in the north of the Tibetan Plateau, the Mojave Basin in the USA, and the Atacama Desert in South America), the subsurface fracture waters in Precambrian cratons (e.g., the Canadian Shield, the Fennoscandian Shield, and the Kaapvaal Craton), high salinity localities (e.g. Laguna de Tírez, salt mines, and deep-sea brines) as well as extremely cold and highly radiative environments (e.g., polar regions, thin atmosphere). These settings on Earth are more accessible for collecting high-quality mineralogical, geochemical, geochronological, and microbiological data by the state-of-the-art facilities. These data can provide a solid cornerstone for us to understand the cycles of water and other life-essential elements, and their impact on habitability and biodiversity in extreme environments on Earth as well as the limits of life and the detection of biosignatures. Such research can also provide vital insights on the search for life on other planets and moons.

Book Description
This book covers the wider aspects of the microbiology of hot desert soil ecosystems, compiling disparate information from a range of relevant desert soil microbial fields. The reader learns about microbial ecology of the more dominant and possibly most important desert habitats, detailing the phylogenetic and functional diversity of these different habitats as well as their potential role in desert ecosystem ecology. Particular attention is also given to microbial stress adaptation in hot desert soils. Furthermore, it is the first volume in this particular field to cover modern metagenomics technologies that can be applied to studies of all aspects of desert microbial communities. Additionally, the book explores viruses and viral communities, which are among the least studied (and little understood) components of desert soil microbial communities. Particular attention is also given to the roles of desert microbial communities in biogeochemical cycling of carbon, nitrogen and phosphorus. Through this book the reader discovers how desert microbiology has been at the forefront of Astrobiology and how it may be used conceptually in future terraforming strategies. Desert ecosystems are increasingly coming into focus given the impacts of climate change and desertification trends, making this volume particularly timely. Each of the chapters is authored by leading international researchers and is a must-read for microbial ecologists.

Book Description
Astrobiology not only investigates how early life took hold of our planet but also life on other planets – both in our Solar System and beyond – and their potential for habitability. The book take readers from the scars on planetary surfaces made by space rocks to the history of the Solar System narrated by those space rocks as well as exoplanets in other planetary systems. But the true question is how life arose here or elsewhere. Modern comparative genomics has revealed that Darwin was correct; a set of highly conserved genes and cellular functions indicate that all life is related by common ancestry. The Last Universal Common Ancestor or LUCA sits at the base of the Tree of Life. However, once that life took hold, it started to diversify and form complex microbial communities that are known as microbial mats and stromatolites. Due to their long evolutionary history and abundance on modern Earth, research on the biological, chemical and geological processes of stromatolite formation has provided important insights into the field of astrobiology. Many of these microbialite-containing ecosystems have been used as models for astrobiology, and NASA mission analogs including Shark Bay, Pavilion and Kelly Lakes. Modern microbialites represent natural laboratories to study primordial ecosystems and provide proxies for how life could evolve on other planets. However, few viral metagenomic studies (i.e., viromes) have been conducted in microbialites, which are not only an important part of the community but also mirror its biodiversity. This book focuses on particularly interesting sites such as Andean lake microbialites, a proxy of early life since they are characterized by very high UV light, while Alchichica and Bacalar lakes are characterized by high-salt and oligotrophic waters that nurture stromatolites. However, it is only the oasis of Cuatro Ciénegas Basin in México that stored past life in its marine sediments of the Sierra de San Marcos. This particular Sierra has a magmatic pouch that moves the deep aquifer to the surface in a cycle of sun drenched life and back to the depths of the magmatic life in an ancient cycle that now is broken by the overexploitation of the surface water as well as the deep aquifer in order to irrigate alfalfa in the desert. The anthropocene, the era of human folly, is killing this unique time machine and with it the memory of the planet.
