Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the existing, up-to-date information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques, characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions, while aspects of P management with respect to animal production and cropping are also presented. The final chapter examines the interactions between global change and P cycling.

Today, human impact on the environment, and especially on the Earth’s surface, is obvious. We increasingly face the consequences of our interventions, and we must pay more attention to the wider impacts of our activities, which include everything from the extraction of fossil fuels to the influence of tourism. Anthropogenic geomorphology, as the study of the way man affects his physical environment, has therefore developed rapidly as a discipline in recent decades. This volume provides guidance to students discussing the basic topics of anthropogenic geomorphology. The chapters cover both its system, and its connections with other sciences, as well as the way the subject can contribute to coping with practical problems. The book represents all fields of geomorphology, giving an introduction to the diversity of the discipline through examples taken from a range of contexts and periods, and focusing on examples from Europe. It is no accident that anthropogenic geomorphology has been gaining ground within geomorphology itself. Its results advance not only the theoretical development of the science but can be applied directly to social and economic issues. Worldwide, anthropogenic geomorphology is an integral and expanding part of the Earth sciences curricula in higher education, making this volume timely and relevant. Key themes: Anthropogenic Geomorphology - Dynamic equilibrium – Environmentalism - Geomorphic processes - Human impact - Man-made landforms József Szabó is Professor Emeritus at the Department of Physical Geography and Geoinformatics, University of Debrecen.

Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms’ innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.
