Book Description
Negative plant-soil feedbacks describe a phenomenon-resulting from interactions between plants and their soil biota, particularly fungal pathogens. These highly dynamic local above- and below-ground interactions may be a way that biodiversity levels are maintained: even if one plant species is a strong competitor, its pathogens suppress its dominance, allowing for the coexistence of multiple plant species. I am interested in how negative feedbacks play a role in determining plant community assembly patterns in a landscape-scale fragmentation field site (Lawrence, Kansas) for which I have over 30 years of historical vegetation data. I built a spatially-explicit cellular automata model of the spatial dynamics of one species, Ambrosia artemisiifolia (common ragweed) over time, across both continuous and fragmented landscapes. Using empirical data from 1985 to set initial conditions, I simulated 32 years of vegetation change and compared the spatial distribution of ragweed in the model to the actual spatial organization of plants from the field site vegetation surveys in 2017. Exploring the spread of ragweed over space and time I asked: as plant communities undergo succession, what spatial patterns of abundance will I observe if negative plant-soil feedbacks are a key driver of plant community composition? Further, how does fragmentation affect these patterns? The model shows that there is a wide range of negative feedback strengths that allow for percent cover levels that resemble the historical data. On the other hand, occupancy, the proportion of samples in which a species is present, requires a much more sensitive range of feedback strengths in order to resemble historical data. In order to yield realistic historical species abundance patterns in the absence of feedbacks, there must be high levels of generalized seed mortality due to other processes. While this model a step towards a more integrated above- and below-ground analysis of spatiotemporal patterns of plant community assembly dynamics, more variables such as abiotic factors, and temporal changes in feedback strength and direction throughout succession must be accounted for, as well as response variables that more accurately represent these patterns.

Book Description
This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential evolutionary consequences of plant-induced soil changes. This is the first volume that specifically highlights the effects of plants on soils and their feedbacks to plants. By contrast, other texts on soil-plant relationships emphasize effects of soil fertility on plants, following the strongly agronomic character of most research in this area. The aspects discussed in this volume are crucial for understanding terrestrial ecosystems, biogeochemistry and soil genesis. The book is directed to terrestrial ecologists, foresters, soil scientists, environmental scientists and biogeochemists, and to students following specialist courses in these fields.

Book Description
In the course of evolution, a great variety of root systems have learned to overcome the many physical, biochemical and biological problems brought about by soil. This development has made them a fascinating object of scientific study. This volume gives an overview of how roots have adapted to the soil environment and which roles they play in the soil ecosystem. The text describes the form and function of roots, their temporal and spatial distribution, and their turnover rate in various ecosystems. Subsequently, a physiological background is provided for basic functions, such as carbon acquisition, water and solute movement, and for their responses to three major abiotic stresses, i.e. hard soil structure, drought and flooding. The volume concludes with the interactions of roots with other organisms of the complex soil ecosystem, including symbiosis, competition, and the function of roots as a food source.

Book Description
This book marshals ecological literature from the last century on facilitation to make the case against the widely accepted individualistic notion of community organization. It examines the idea that positive interactions are more prevalent in physically stressful conditions. Coverage also includes species specificity in facilitative interactions, indirect facilitative interactions, and potential evolutionary aspects of positive interactions.

Book Description
This book investigates soil ecology and biodiversity for its ability to maintain a balance of beneficial organisms to support plant growth. This subject is discussed by a group of international authors in natural, agricultural and urban systems. The importance of biodiversity per se and, specifically, the feedbacks between the plant and soil biota in mediating soil function are emphasized. Examples are selected from allelopathy and invasive plant species along with the, hitherto overlooked, role of viruses in soil. The book is intended to provide a framework for a holistic understanding of the essential role of soil organisms in promoting plant growth.

Book Description
The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi tive exclusion and the apparent contradiction between the competitive exclu sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence have been debated. On the one extreme, some ecologists have taken competi tion for granted and have used it as an explanation by default if the distribu tion of a species was more restricted than could be explained by physiology and dispersal history. For decades, competition has been a core mechanism behind popular concepts like ecological niche, succession, limiting similarity, and character displacement, among others. For some, competition has almost become synonymous with the Darwinian "struggle for existence", although simple plausibility should tell us that organisms have to struggle against much more than competitors, e.g. predators, parasites, pathogens, and envi ronmental harshness.

Book Description
This textbook covers Plant Ecology from the molecular to the global level. It covers the following areas in unprecedented breadth and depth: - Molecular ecophysiology (stress physiology: light, temperature, oxygen deficiency, drought, salt, heavy metals, xenobiotica and biotic stress factors) - Autecology (whole plant ecology: thermal balance, water, nutrient, carbon relations) - Ecosystem ecology (plants as part of ecosystems, element cycles, biodiversity) - Synecology (development of vegetation in time and space, interactions between vegetation and the abiotic and biotic environment) - Global aspects of plant ecology (global change, global biogeochemical cycles, land use, international conventions, socio-economic interactions) The book is carefully structured and well written: complex issues are elegantly presented and easily understandable. It contains more than 500 photographs and drawings, mostly in colour, illustrating the fascinating subject. The book is primarily aimed at graduate students of biology but will also be of interest to post-graduate students and researchers in botany, geosciences and landscape ecology. Further, it provides a sound basis for those dealing with agriculture, forestry, land use, and landscape management.
