Every topic has been updated with information obtained from the most recent primary literature.
• The Diversity section has undergone the most obvious revision based on molecular systematics and the comparison of DNA and RNA sequences. Chapters follow the principle of monophyly throughout, and include the latest taxon names and updated cladograms.
• The Physiology of Seed Plants section now includes new information on hormone receptors, the formation of lateral roots, the floral stimulus, thigmonastic movements, strategies to acquire nutrients, nocturnal transpiration, and hydraulic redistribution.
• The dual themes of evolution and ecology are integrated throughout at the molecular, cellular, organismal, and plant community levels. Emphasis is placed on the ecological significance of prokaryotes, fungi, bryophytes, and the root systems of plants to the global carbon cycle and global warming.
New illustrations and photographs enhance the book's long-acclaimed art program.
New ecology essays showcase ecologically relevant stories to bring the concepts to life.
New chapter openers include photos with captions that engage student interest with fascinating topics, many of which involve ecological applications.
