Book Description
The chapters in this volume are based on a opportumtles for studying the links between symposium, "California grasslands: structure abiotic and biotic components. and productivity", supported by the National The contributions in this volume illustrate Science Foundation. The primary objective of the links between population-level processes this symposium was to integrate the current and system-level phenomena in a well-studied understanding of controls on ecosystem struc community. Unfortunately, some areas of cur ture and function with the approaches of popu rent research (e.g., nutrient cycling) are under lation biology. The annual grasslands are represented in this volume. For other topics eminently suitable for experimental and manip (particularly the role of invertebrate con sumers), the lack of data from the annual grass ulative studies of ecosystem processes. The short lives and small stature of the component land brought a broader grassland perspective. plant species make experimental work far more Together, however, the contributions illustrate practical than in forests or even in perennial the importance of different ecological ap dominated prairies. The system's small-scale proaches in studying the controls on structure patchiness, and the obvious importance of and function of a complex system. the region's mediterranean climate in the life cycle of the annual vegetation, afford many L.F.

Book Description
This book is a pioneer attempt to bring forward the first synthesis on the most diverse and threatened mountain top vegetation of South America, the rupestrian grasslands. It brings to light the state of the art information on this ecosystem geology, soil formation and distribution, environmental filters that lead to biodiversity, species interactions and their fine tuned adaptations to survive the harsh mountain environment. The human dimensions of the rupestrian grassland are also addressed, including the anthropogenic threats that may irreversibly impact biodiversity and ecosystem services. The book also highlights the ongoing studies on ecological restoration and first attempt to model the impacts of climate change on its speciose biota.
