Only a small part of the spatio-temporal structures of earthworm distribution was correlated with soil properties. Small species were more abundant in patches were soil was more compact, while large species were associated with high root biomass and total C levels. The question whether earthworm ...

General conclusions, research highlights, and future needs
Earthworms are generally considered to fulfill the definition of ecosystem engineers. The casts they produce are recognised to have a great importance in the regulation of soil processes. Lifetimes and degradation rates of these structures remain poorly known. In this study, the dynamics of disap...

Degradation dynamics of surface earthworms casts in grasslands of the Eastern plains of Colombia
Earthworms are considered soil ecosystem engineers that play an important role in soil organic matter dynamics and physical structure. Due to both their size and activities these organisms can accelerate the decomposition and mineralization of organic matter by reducing the size of residues to pa...

Earthworm functional traits, landscape degradation and ecosystem services in the Brazilian Amazon deforestation arc
The vertical distribution of native earthworm species from natural and disturbed savannas in the Oxisols of the Colombian Llanos was assessed in a native savanna and in a 17-year-old grazed grass-legume pasture during a period of 17?months. Different patterns of vertical stratification were obser...

The effect of different types of land management on the soil macrofauna of the savanna has been assesed using the T.S.B.F. method. Macrofauna of the forest and savanna has a high density (4293 and 2830 ind.m(2)) and moderate biomass (13.6 and 15.3 g.m(-2)). Traditional grazing significantly incre...
