Francesca Pacchierotti,Antonella Sguramillion years (Ma) suggests a massive injection of biogenic methane into the ocean/atmosphere system. The clathrate gun hypothesis (Kennet et al. 2003) proposes that changes in the temperature of intermediate seawater led to a destabalization of methane hydrates, produced by anaerobic chemotrophic a

Geochemical Flows in Landscapesl species that colonized the Galápagos 2–3 million years ago. Each species occupies a distinct and unique feeding niche. For evolutionary biologists, they pose a challenge. What is the explanation for the evolution of such a variety of species in a relatively short space of time? What governs the ra

Geochemical Flows in Landscapesthey pose a challenge. What is the explanation for the evolution of such a variety of species in a relatively short space of time? What governs the rate of speciation and the directions of evolution? Answers to these questions are of general significance in the context of understanding why the world is so rich biologically.

Handbook of Environmental Engineeringmple. We discuss the apparent accelerated rate of mutation at the very tips of the trees because of the lag of purifying selection and how this effect provides a framework for understanding the dynamic interplay between molecular evolution and ecology.
