This book presents a broad view of contemporary research in evolutionary plant ecology. It illustrates the broad spectrum of life history stages which affect plant reproductive success in some fashion.Preface -- Introduction Herbert Baker: A Renaissance Botanist -- Evolutionary Dynamics -- Plastids in a Changing Environment -- Adaptive Shifts Toward Hummingbird Pollination -- Early Maturity, Small Flowers and Autogamy: A Developmental Connection? -- Chromosome Variation and Evolution in American and Asian Trillium Species -- Polyploid Polymorphism in Grasses of the North American Prairie -- The Genetic Structure of Tropical Tree Populations: Associations with Reproductive Biology -- Breeding Systems -- The Evolutionary Breakdown of Heterostyly -- Facultative Xenogamy: Examination of a Mixed Mating System -- BakerS Law: Plant Breeding Systems and Island Colonization -- Reproductive Biology -- Pollenkitt in Plant Reproduction -- Reproductive Biology of Hibiscus Moscheutos (Malvaceae) -- Relationships between Components of Plant form and Seed Output in Collinsonia Verticillata (Lamiaceae) -- Size Dependent Reproduction in Poa Annua and P.
