- An emerging research line in conservation ecology
addresses how environmental change drivers may cause the biotic
homogenization of ecological communities by shifts in species diversity
and community composition. While the drivers have been explored in
unmanaged ecosystems and managed agricultural systems, this issue has
received limited attention in regards to a key soil bioindicator
organisms, soil nematodes.
- In this study, we evaluated the effect of land-use
change and intensification on the diversity of plant-feeding nematodes
(PFN) thought taxonomic and functional measures of alpha and beta
diversity. We selected olive tree farms in southern Spain as the study
system, given the wide distribution of wild forms in unmanaged systems
and cultivated forms in agricultural systems, thus providing the
opportunity to assess the effects of land use intensity.
- Notably, our study revealed that the conversion from
natural to agricultural systems and even moderate increases in land-use
intensity caused a significant biotic homogenization by enhancing the
functional similarities of PFN communities. Our study emphasizes the key
role of body size in structuring nematode communities in response to
land-use type and intensity.
- Synthesis and applications. The importance of
soil nematodes in soil processes is well known. We show that land use
intensification reduces soil nematode diversity. Our study has important
implications for the development of management strategies that foster
soil biodiversity conservation such as no or minimal tillage and
logging, vegetative covers and the maintenance of natural habitat.
