Fire has shaped the Earth's landscape and vegetation for the past 400 million years. This book explores the history of wildfire, and how humans have sought to use and manage it. The need to understand fire has never been greater, as human settlements encroach on flammable landscapes and wildfires increase with climate change.

Andrew Scott, who played a key role in identifying fossilized charcoal, describes the profound impact of fire through Earth history, from its role in mass extinctions and the spread of flowering plants, to early hominid use of fire, and the role of wildfires on landscapes today.

Molecular biology techniques have considerably improved our understanding of the mechanisms underlying the control of flower initiation, development, function, and senescence. These processes are extremely important for managing the yield of agricultural crops. The essays in this volume discuss the molecular and genetic control of flower morphogenesis in particular species as well as the role and regulation of gene expression in the development of the male and female gametes in plant reproduction. They also review the considerable variation in the longevity and pattern of senescence of...
