Conservation and biodiversity of protists The conservation of biodiversity is not just an issue of plants and vertebrates. It is the scarcely visible invertebrates and myriads of other microscopic organisms that are crucial to the maintenance of ecological processes on which all larger organisms and the composition of the atmosphere ultimately depend. Biodiversity and Conservation endeavours to take an holistic view of biodiversity, and when the opportunity arises to issue collections of papers dealing with too-often neglected groups of organisms. The protists, essentially eukaryotes that cannot be classi?ed in the kingdoms of animals, fungi, or plants, include some of the lea- known groups ...

Bringing together the viewpoints of leading experts in taxonomy, ecology and biogeography of different taxa, this book synthesises discussion surrounding the so-called 'everything is everywhere' hypothesis. It addresses the processes that generate spatial patterns of diversity and biogeography in organisms that can potentially be cosmopolitan. The contributors discuss questions such as: are microorganisms (e.g. prokaryotes, protists, algae, yeast and microscopic fungi, plants and animals) really cosmopolitan in their distribution? What are the biological properties that allow such potential distribution? Are there processes that would limit their distribution? Are microorganisms intrinsically different from macroscopic ones? What can microorganisms tell us about the generalities of biogeography? Can they be used for experimental biogeography? Written for graduate students and academic researchers, the book promotes a more complete understanding of the spatial patterns and the general processes in biogeography.

Soil Biota, Nutrient Cycling and Farming Systems is a timely reference volume that explores the relationship between soil biota and environmental and agricultural practices. It addresses topics such as agroecosystems structure and function, cycling of nutrients and soil contamination, use of soil invertebrates as soil bioindicators, application of organic matter to soil, and impact of high-input agriculture to sustainable agriculture. The book will be important for anyone studying sustainable agriculture, agroecology, soil interacting processes, crop science, environmental contamination, and landscape ecology.
This study describes 656 species of bacteria, protists, and micro-metazoa occurring in the Simmelried, a three hectare-sized moorland near to the town of Constance, southern Germany. Each species is shown by an average of two colour micrographs. Further, the surface organization of most main groups and many ciliate species is demonstrated by scanning electron micrographs.The Simmelried formed after the last (Würm) ice-age, that is, about 15.000 years ago, when a regressing glacier tongue produced a terrain with water-filled depressions between streamlined boulder depositions. The investigations indicate that the 656 species documented represent only two thirds of the taxa actually present. ...
The present monograph carefully revises the taxonomy, nomenclature, and ecology of all nominal species of spathidiids and shows that spathidiid diversity has been greatly underestimated. Based on the reinvestigation of described species with modern methods and the first description of over 50 new species, the family Spathidiidae is split into four families and 20 genera. Each species is described and figured in detail. Two identification keys are provided.
Throughout history, many leading thinkers have been inspired by the parallels between nature and human design, in mathematics, engineering and other areas. This book publishes the results of a conference on the significance of nature for design.
