This book attempts to provide a soundly based introduction to those features of the atmospheric environment of particular relevance to plants; it also describes the physical and physiological principles required for understanding how these factors affect plants. The underlying biophysics and biochemistry are explained in the context of plants growing in their natural environment. For example, gas exchange and diffusion are considered in relation to the control both of evaporation from vegetation and of photosynthesis and productivity, while energy exchanges are examined in relation to plant temperature regulation. Throughout the text a quantitative approach is adopted and the use of mathematical models is described with some examples. Physiological and ecological aspects of adaptation to different natural environments, including mechanisms of drought tolerance, are considered, as are possible ways in which this information can be used for improving crop plants for selective breeding. Practical aspects of important measurement techniques are discussed. There is a comprehensive reference list giving an introduction to recent literature, together with appendixes listing useful physical qualities. The presentation adopted is designed to emphasize the close relationship among the biophysical, physiological, and ecological aspects of the adaptation of higher plants to their aerial environment. This second edition has been fully updated and includes information on novel techniques such as chlorophyll-a fluorescence and carbon isotope discrimination, which can be applied to plants in the field, as well as coverage of topics of current concern such as global warming and atmospheric pollution.

Ecosystems across the world are experiencing increased invasion events by invasive plant species (IPS) that can dramatically alter the species composition of native plant communities as well as interactions with local fauna, and can ultimately impact human well-being itself. Human activities have been shown to play a significant role in the establishment of IPS either by direct interventions such as introducing them, or indirectly by altering global climate, increasing available nutrients through air pollution or weakening biotic resistance to invasion of native plant communities by physically disturbing them. This study aims to investigate the effect of disturbance (biotic as well as abiotic) and microclimate on the colonization of 6 non-native plant species at an elevation of 1000 m asl in a Swedish subarctic mountain ecosystem, as well as to determine whether the main interaction between native and non-native plants was dominated by competition or facilitation. Both non-native plant biomass and presence/absence were studied over 2 growing seasons and 1 winter by sowing seeds in either disturbed or undisturbed subplots under various propagule pressure and fertilization treatments, and orientation of the slope on which plots were installed (either North or South) on two mountains. These factors, along with variation in soil temperature were investigated using linear mixed models and generalized linear mixed models. Results show that disturbance was the main factor determining non-native success, with plants in disturbed treatment groups doing significantly better than those in undisturbed groups. Both non-native biomass and presence were shown to follow a climatic gradient during the growing season, while no effect on biomass was observed during winter. A high propagule pressure leads to an increased chance of non-native presence, but does not influence their size, while fertilization leads to an increase in size but not in chance of presence. Native and non-native biomass were negatively correlated. Facilitation by native plants was not observed. The findings of this study emphasize the need of further research, while stressing the importance of preventing introduction of IPS in a context of global climate change for combatting the loss of native flora in mountains.

Contributed to by leading experts, this book looks at the history of coppice woodlands, their physical environment, the different management techniques used and their effects on the flora and fauna. The implications of this for conservation is controversial and this is debated in a lively way in many of the chapters.

Advances in Ecological Research, first published in 1962, is one of Academic Press's most successful and prestigious series. In 1999, the Institute for Scientific Information released figures showing that the serial has an Impact Factor of 9.6, with a half life of 10.0 years, placing it 1st in the highly competitive category of Ecology. The Editors have always striven to provide a wide range of top-quality papers on all aspects of ecology, such as animal/plant, physiology/population/community, landscape and ecosystem ecology. Eclectic volumes in the serial are supplemented by thematic volumes on such topics as Estuaries and Ancient Lakes. Now edited by Dr Hal Caswell, of Woods Hole Oceanographic Institution, Advances in Ecological Research continues to publish topical and important reviews, interpreting ecology as widely as in the past, to include all material that contributes to our understanding of the field.
