Landscape Evolution: Landforms, Ecosystems and Soils asks us to think holistically, to look for the interactions between the Earth's component surface systems, to consider how universal laws and historical and geographical contingency work together, and to ponder the implications of nonlinear dynamics in landscapes, ecosystems, and soils. Development, evolution, landforms, topography, soils, ecosystems, and hydrological systems are inextricably intertwined. While empirical studies increasingly incorporate these interactions, theories and conceptual frameworks addressing landforms, soils, and ecosystems are pursued largely independently. This is partly due to different academic disciplines, traditions, and lexicons involved, and partly due to the disparate time scales sometimes encountered. Landscape Evolution explicitly synthesizes and integrates these theories and threads of inquiry, arguing that all are guided by a general principle of efficiency selection. A key theme is that evolutionary trends are probabilistic, emergent outcomes of efficiency selection rather than purported goal functions. This interdisciplinary reference will be useful for academic and research scientists across the Earth sciences. Serves as a primary theoretical resource on landscape evolution, Earth surface system development, and environmental responses to climate and land use change Incorporates key ideas on geomorphic, soil, hydrologic, and ecosystem evolution and responses in a single book Includes case studies to provide real-world examples of evolving landscapes

General scientific laws guide and constrain how landscapes evolve, but because local geographical and historical contingencies are so important, there are infinite possible evolutionary pathways and outcomes. Nevertheless, certain patterns, structures, and relationships recur repeatedly that tend to maximize efficiency. But no laws determine that this should happen, and landscapes have no goals or intentionality. How does nature keep producing relationships, structures, and patterns that maximize efficiency? Those are the "mysterious ways " this book explains.Drawing from a broad range of geoscience, bioscience, and other sciences, Mysterious Ways speaks to the stories we tell about how our world came to be, how it changes, and our place in it. The book makes a case for evolution and selection as general phenomena in nature. It shows how evolution and selection operate at the level of landscapes, and how landforms, soils, hydrology, and biota coevolve as they mutually adapt to climate and other environmental changes. It looks at phenomena like the transformation of tropical forests to savannas, karsts to deserts, and riverbed formation as outcomes of tendencies for more efficient, stable, and durable patterns, structures, and relationships to form, grow, replicate, and persist.
