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.
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. Thus, a considerable diversity accumulated over 15.000 years, emphasizing the great distribution capacity of micro-organisms. On the other hand, some common species are lacking (e. g., the ciliate Colpidium colpoda, the euglenid Phacus pleuronectes, and rotifers of the genera Proales and Floscularia) and many undescribed species were discovered. While a mass of undescribed species is comprehensible in amoebas, flagellates and ciliates, which are poorly researched, this is surprising in weII-known groups, such as euglenids and chrysophytes. Thus, we must face the possibility that some of the undescribed species are regional or Iocal endemics. The high species richness, induding many undescribed species, suggests the Simmelried as a regional biodiversity centre worth to be protected by law.

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.
