“…While at the global scale temperature and rainfall regimes determine the structure and composition of earthworm communities (Brussaard et al., ; Rutgers et al., ), at regional and local scales they also have a direct influence on the size of their populations and on their responses to agricultural inputs (e.g. Boudiaf, Metheri, Mouas, & Derridj, ; Velki & Ecimovic, ). However, tillage practices can override earthworms' environmental tolerance limits (Nieminen et al., ), making it difficult to disentangle the relative significance of each driver on the overall response.…”

AbstractThe adoption of less intensive soil cultivation practices is expected to increase earthworm populations and their contributions to ecosystem functioning. However, conflicting results have been reported on the effects of tillage intensity on earthworm populations, attributed in narrative reviews to site-dependent differences in soil properties, climatic conditions, and agronomic operations (e.g., fertilization, residue management and chemical crop protection).We present a quantitative review based on a global meta-analysis, using paired observations from 215 studies performed over 65 years across 40 countries on five continents, to elucidate this long-standing unresolved issue. Results showed that disturbing the soil less (e.g., no-tillage and Conservation Agriculture) significantly increased earthworm abundance (mean increase of 137% and 127%, respectively) and biomass (196% and 101%, respectively) compared to when the soil is inverted by conventional ploughing. Earthworm population responses were more pronounced when the soil had been under reduced tillage for a long time (>10 years), in warm temperate zones with fine-textured soils, and in soils with higher clay contents (>35%) and low pH (<5.5). Furthermore, retaining organic harvest residues amplified this positive response to reduced tillage, whereas the use of the herbicide glyphosate did not significantly affect earthworm population responses to reduced tillage.Additional meta-analyses confirmed that epigeic and, more importantly, the bigger-sized anecic earthworms, were the most sensitive ecological groups to conventional tillage. In particular, the deep burrower Lumbricus terrestris exhibited the strongest positive response to reduced tillage, increasing in abundance by 124% more than the overall mean of all 13 species analysed individually. The restoration of these two important ecological groups of earthworms and their burrowing, feeding and casting activities under various forms of reduced tillage will ensure the provision of ecosystem functions such as soil structure maintenance and nutrient cycling by "nature's plough".

“…In the case of organic contaminants, the volatilization could increase biotransformation, photodegradation, and biodegradation so that their removal or degradation occurs more favorably than transportation by surface runoff [20,43,[58][59][60]68,69]. Some pesticides could also cause a higher level of oxidative stress to the soil organisms (e.g., earthworms) while they are exposed to the elevated ambient temperature (25 • C compared to 20 • C) [70].…”

Heavy metal(loid)s and organic contaminants are two major groups of pollutants in soils. The fate and exposure of such pollutants in soil depends on their chemical properties, speciation, and soil properties. Soil properties and processes that control the toxicological aspects of pollutants include temperature, moisture, organic matter, mineral fractions, and microbial activities. These processes are vulnerable to climate change associated with global warming, including increased incidences of extreme rainfall, extended dry periods, soil erosion, and a rise in sea level. Here we explain evidence that relates to the effects of climate change-driven soil processes on the mobility, transport, and storage of pollutants in soil. The review found that changes in climate could increase human exposure to soil contaminants mainly due to processes involving soil organic carbon (SOC), surface runoff, redox state, and microbial community. However, uncertainties remain in relation to the extent of contaminant toxicity to human health, which is linked to global change drivers.

“…Another study performed by Garcia et al (2008) assessed effects of three pesticides on the avoidance behavior of earthworms in laboratory tests performed under temperate and tropical conditions and the results of the avoidance tests did not give a clear answer whether data from tests performed under temperate conditions can be used for pesticide risk assessment in tropical regions. In our recent study (Velki and Ečimović 2015) the toxicity of several insecticides, fungicides and herbicides on the mortality of earthworms at low and high temperature was assessed and an increase in exposure temperature generally led to an increase in toxicity, whereas a decrease in exposure temperature led to a decrease in toxicity. However, there were also some discrepancies (e.g.…”

The importance and beneficial effects of earthworms on soil structure and quality is well-established. In addition, earthworms have proved to be important model organisms for investigation of pollutant effects on soil ecosystems. In ecotoxicological investigations effects of various pollutants on earthworms were assessed. But some important issues regarding the effects of pollutants on earthworms still need to be comprehensively addressed. In this review several issues relevant to soil ecotoxicological investigations using earthworms are emphasized and guidelines that should be adopted in ecotoxicological investigations using earthworms are given. The inclusion of these guidelines in ecotoxicological studies will contribute to the better quantification of impacts of pollutants and will allow more accurate prediction of the real field effects of pollutants to earthworms.
