Vitis vinifera is a common plant species cultivated in Southern Brazil for vine production. Although this plant species is commonly found near the Mixed Ombrophilous Forest, the V. vinifera plantation is cultivated in areas for a long-term thus changing the soil ecosystem and functional diversity. We aimed to compare the soil chemical properties, s...

Chapter
This chapter explores how natural and invaded ecosystem provide habitat and energy supply for the entire soil food web, how biological invasion changes habitat of the soil organisms, and two study cases considering invasive plant species (Cryptostegia madagascariensis and Prosopis juliflora) from tropical zones. Natural ecosystem is defined as a co...
Chapter
In this chapter, the soil ecosystem is introduced as a multiphase system that (i) acts as habitat for a wide diversity of soil organisms and (ii) varies at both spatial and temporal scale. The soil formation varies according to a combination of geological factors and biological process (e.g., here included the influence of mankind) that result in a...
