Ecological restoration, although a relatively new endeavour compared to other disciplines, has gained significant momentum during the last decade as accelerating global change becomes more apparent. It is now widely accepted by the scientific community that to avoid further devastating effects of climate change and biodiversity loss, humanity must determinedly move more to protect and restore natural ecosystems. Many restoration efforts of the past have been ad hoc, site and situation-specific and have often failed to achieve desired outcomes, but over the last decade, many countries are allocating increasingly significant amounts of financial investment towards restoration with the goal of ...
Aquatic plants play a critically important role in maintaining ecosystem health. They are natural biological filters in freshwater and estuarine wetlands; they contribute to the reproductive success of many organisms, some of which are harvested for food; they assist in flood control; and they are prominent elements in the aesthetics and recreational use of freshwater and estuarine habitats. Despite this globally recognized importance, wetlands have faced and continue to face threats from the encroachment of human activities. The Biology of Aquatic and Wetland Plants is a thorough and up-to-date textbook devoted to these plants and their interactions with the environment. The focus is on bot...
This book describes the unique characean experimental system, which provides a simplified model for many aspects of the physiology, transport and electrophysiology of higher plants. The first chapter offers a thorough grounding in the morphology, taxonomy and ecology of Characeae plants. Research on characean detached cells in steady state is summarised in Chapter 2, and Chapter 3 covers characean detached cells subjected to calibrated and mostly abiotic types of stress: touch, wounding, voltage clamp to depolarised and hyperpolarised potential difference levels, osmotic and saline stress. Chapter 4 highlights cytoplasmic streaming, cell-to-cell transport, gravitropism, cell walls and the role of Characeae in phytoremediation. The book is intended for researchers and students using the characean system and will also serve as an invaluable reference resource for electrophysiologists working on higher plants.
Vegetation communities in Australia's riverine landscapes are ecologically, economically and culturally significant. They are also among the most threatened ecosystems on the continent and have been dramatically altered as a result of human activities and climate change. Vegetation of Australian Riverine Landscapes brings together, for the first time, the results of the substantial amount of research that has been conducted over the last few decades into the biology, ecology and management of these important plant communities in Australia. The book is divided into four sections. The first section provides context with respect to the spatial and temporal dimensions of riverine landscapes in A...
This collection of papers originated from a series of field workshops held after the Annual Congress of the Australian Society for Limnology in 1991, and published in a special issue of the Australian Journal of Marine and Freshwater Research. Presents a background to plants and processes in wetlands and discusses topics such as classification of water regimes in systems of fluctuating water level, seasonal germination from wetland seed banks, and biomass and above-ground productivity of salt-marsh plants in south eastern Australia. Includes references.

The "world of letters" has always seemed a matter more of metaphor than of global reality. In this book, Pascale Casanova shows us the state of world literature behind the stylistic refinements--a world of letters relatively independent from economic and political realms, and in which language systems, aesthetic orders, and genres struggle for dominance. Rejecting facile talk of globalization, with its suggestion of a happy literary "melting pot," Casanova exposes an emerging regime of inequality in the world of letters, where minor languages and literatures are subject to the invisible but implacable violence of their dominant counterparts. Inspired by the writings of Fernand Braudel and Pi...
