Soil Invertebrates [PDF ebook] 
Kaleidoscope of Adaptations

Soil invertebrates make up diverse communities living in soil pores and on the soil surface, digging burrows and tunnels, processing organic matter and interacting with microbes. Soil is also a habitat of growing concern as many human activities cause soil degradation. This book documents the evolutionary history of soil invertebrates and their multitude of adaptations. Soil invertebrates live in a twilight zone: some have gone down to seek stability, constancy and rest, others have gone up and faced environmental variation, heat, cold and activity. And it all happens in a few decimetres, millimetres sometimes. Check out the wonderful life below ground in this book.
