| Zusammenfassung |
| Soil is a key asset of natural capital, providing a myriad of goods and
ecosystem services that sustain life through regulating, supporting and
provisioning roles, delivered by chemical, physical and biological
processes. One of the greatest threats to soil is accelerated erosion, which
raises a natural process to unsustainable levels, and has downstream
consequences (e.g.~economic, environmental and social). Global
intensification of agroecosystems is a recognised major cause of soil
erosion which, in light of predicted population growth and increased demand
for food security, will continue or increase. Transport and redistribution
of biota by soil erosion has hitherto been ignored and thus is poorly
understood. With the move to sustainable intensification this is a key
knowledge gap that needs to be addressed. Here we highlight the
erosion-energy and effective-erosion-depth continuum in soils,
differentiating between different forms of soil erosion, and argue that
nematodes are an appropriate model taxa to investigate impacts of erosion on
soil biota across scales. We review the different known mechanisms of soil
erosion that impact on soil biota in general, and nematodes in particular,
and highlight the few detailed studies, primarily from tropical regions,
that have considered soil biota. Based on the limited literature and
using nematodes as a model organism we outline future research priorities to
initially address the important interrelationships between soil erosion
processes and soil biota. |
