The effects of stressful conditions on plants such as drought, salinity, waterlogging, and high and low temperatures can have a major impact on plant growth and survival, with important economic consequences in crop plants. This book explores some of the more important stresses, demonstrates how they affect the plant and reviews how new varieties or new species less vulnerable to stress can be selected.

The theory of accommodation is concerned with motivations underlying and consequences arising from ways in which we adapt our language and communication patterns toward others. Since accommodation theory's emergence in the early l970s, it has attracted empirical attention across many disciplines and has been elaborated and expanded many times. In Contexts of Accommodation, accommodation theory is presented as a basis for sociolinguistic explanation, and it is the applied perspective that predominates this edited collection. The book seeks to demonstrate how the core concepts and relationships...

This book, a revised and extended version of Professor Davies's 1988 Wiles Lectures, explores the ways in which the kings and aristocracy of England sought to extend their domination over Ireland, Scotland and Wales in the twelfth and thirteenth centuries. It analyses the mentalities of domination and subjection - how the English explained and justified their pretensions and how native rulers and societies in Ireland and Wales responded to the challenge. It also explains how the English monarchy came to claim and exercise a measure of 'imperial' control over the whole of the British Isles by...

In recent years an increasing number of interpreters have found dramatic and verbal ironies widely distributed in Mark's Gospel. This lucid study makes an important contribution to our understanding of Mark's irony, and combines a literary-critical approach with insights gained from the sociology of knowledge. Professor Camery-Hoggatt argues that Mark's ironies are intentional, and that irony comprises an integral factor in Mark's overall strategy of composition: irony is a subtle means to achieve apologetic and paradigmatic ends.

Plants convert inorganic nitrogen into amino acids, the building blocks for proteins. They also make a wide range of other nitrogen compounds to help protect themselves from pests and diseases. An understanding of these compounds can therefore help in devising better crop protection and production methods. This volume contains essays by scientists who have studied aspects of plant nitrogen nutrition and amino acid biosynthesis. There are chapters on protein amino acids, nonprotein amino acids, betaines, glutathione, polyamines, and other secondary metabolites derived from amino acids. The...

Global warming and climate change are growing environmental concerns. The potential impact on freshwater and marine fish is immense, because most fish have no physiological ability to regulate their body temperature. This volume focuses on the effects of temperature at all levels of organization in fish, with particular emphasis on physiological function: cells, epithelia, organ systems, the whole organism, reproduction, behavior, pollutant interactions, ecology and population dynamics. Written by experts in the field, many chapters also speculate on the long-term physiological and ecological...
