Book Description
Evolutionary biology has long sought to explain how new traits and new species arise. Darwin maintained that competition is key to understanding this biodiversity and held that selection acting to minimize competition causes competitors to become increasingly different, thereby promoting new traits and new species. Despite Darwin’s emphasis, competition’s role in diversification remains controversial and largely underappreciated. In their synthetic and provocative book, evolutionary ecologists David and Karin Pfennig explore competition's role in generating and maintaining biodiversity. The authors discuss how selection can lessen resource competition or costly reproductive interactions by promoting trait evolution through a process known as character displacement. They further describe character displacement’s underlying genetic and developmental mechanisms. The authors then consider character displacement’s myriad downstream effects, ranging from shaping ecological communities to promoting new traits and new species and even fueling large-scale evolutionary trends. Drawing on numerous studies from natural populations, and written for a broad audience, Evolution’s Wedge seeks to inspire future research into character displacement’s many implications for ecology and evolution.

Book Description
Structural geology has developed at a very rapid pace in recent years. Evolution of Geological Structures in Micro- to Macro-Scales, covering a wide spectrum of current research in structural geology from the grain scale to the scale of orogenic belts and from the brittle to the ductile field, provides an overview of newly emerging concepts in a single volume. The book covers a wide range of advances in such broad fields as hydraulic factures, normal faults, overthrusts, ductile shear zones, rock fabrics, folds, superposed folds and basement structures.

The Role of Volatiles in the Genesis, Evolution and Eruption of Arc Magmas

Book Description
The subduction zone volatile cycle is key to understanding the petrogenesis, transport, storage and eruption of arc magmas. Volatiles control the flux of slab components into the mantle wedge, are responsible for melt generation through lowering the solidi of mantle materials and influence the crystallizing phase assemblages in the overriding crust. Further, the rates and extents of degassing during magma storage and decompression affect magma rheology, ultimately control eruption style and have consequences for the environmental impact of explosive arc volcanism. This book highlights recent progress in constraining the role of volatiles in magmatic processes. Individual book sections are devoted to tracing volatiles from the subducting slab to the overriding crust, their role in subvolcanic processes and eruption triggering, as well as magmatic-hydrothermal systems and volcanic degassing. For the first time, all aspects of the overarching theme of volatile cycling are covered in detail within a single volume.

Book Description
This book deals with recent developments in evolutionary models for convergent margins. Reflecting transient modes for oceanic plate convergence, such boundaries are sites of varied tectonic processes, which provoke vigorous material recycling and frequent natural disasters such as massive earthquakes and catastrophic volcanism. Therefore, the origin of their diversity has long been one of the most significant themes in Earth science. The important scientific results obtained by prominent researchers who contributed chapters to this book pave the way for further in-depth studies on mobile belt frontiers, where harsh conditions hinder efforts to understand the Earth's spatiotemporal changes.

Book Description
What Doesn't Kill Us, a New York Times bestseller, traces our evolutionary journey back to a time when survival depended on how well we adapted to the environment around us. Our ancestors crossed deserts, mountains, and oceans without even a whisper of what anyone today might consider modern technology. Those feats of endurance now seem impossible in an age where we take comfort for granted. But what if we could regain some of our lost evolutionary strength by simulating the environmental conditions of our ancestors? Investigative journalist and anthropologist Scott Carney takes up the challenge to find out: Can we hack our bodies and use the environment to stimulate our inner biology? Helping him in his search for the answers is Dutch fitness guru Wim Hof, whose ability to control his body temperature in extreme cold has sparked a whirlwind of scientific study. Carney also enlists input from an Army scientist, a world-famous surfer, the founders of an obstacle course race movement, and ordinary people who have documented how they have cured autoimmune diseases, lost weight, and reversed diabetes. In the process, he chronicles his own transformational journey as he pushes his body and mind to the edge of endurance, a quest that culminates in a record-bending, 28-hour climb to the snowy peak of Mt. Kilimanjaro wearing nothing but a pair of running shorts and sneakers. An ambitious blend of investigative reporting and participatory journalism, What Doesn’t Kill Us explores the true connection between the mind and the body and reveals the science that allows us to push past our perceived limitations.
