“…The gap of knowledge that still remains after our study is that the effects of earthworms have almost solely been studied in the absence of plants and without considering plant growth. As the effects of earthworms on plant growth are generally positive (van Groenigen et al, 2014), the disservice of increased N 2 O emissions may be counteracted by enhanced plant growth to the degree that no increase in yield-scaled emissions results (Wu et al, 2015). Extrapolation from our results to field scale may not be simple either as the effect of midden density on GHG production is not necessarily linear due to resource competition among earthworm individuals.…”

Abstract.We studied the effect of the deep-burrowing earthworm Lumbricus terrestris on the greenhouse gas (GHG) fluxes and global warming potential (GWP) of arable no-till soil using both field measurements and a controlled 15-week laboratory experiment. In the field, the emissions of nitrous oxide (N 2 O) and carbon dioxide (CO 2 ) were on average 43 and 32 % higher in areas occupied by L. terrestris (the presence judged by the surface midden) than in adjacent, unoccupied areas (with no midden). The fluxes of methane (CH 4 ) were variable and had no consistent difference between the midden and non-midden areas. Removing the midden did not affect soil N 2 O and CO 2 emissions. The laboratory results were consistent with the field observations in that the emissions of N 2 O and CO 2 were on average 27 and 13 % higher in mesocosms with than without L. terrestris. Higher emissions of N 2 O were most likely due to the higher content of mineral nitrogen and soil moisture under the middens, whereas L. terrestris respiration fully explained the observed increase in CO 2 emissions in the laboratory. In the field, the significantly elevated macrofaunal densities in the vicinity of middens likely contributed to the higher emissions from areas occupied by L. terrestris. The activity of L. terrestris increased the GWP of field and laboratory soil by 50 and 18 %, but only 6 and 2 % of this increase was due to the enhanced N 2 O emission. Our results suggest that high N 2 O emissions commonly observed in no-till soils can partly be explained by the abundance of L. terrestris under no-till management and that L. terrestris can markedly regulate the climatic effects of different cultivation practises.

“…Of those studies, 43% attempted to measure trade‐offs and synergies between services and disservices. The methods used to quantify these trade‐offs ranged from correlations or relative scoring of disservices and services (Helfenstein & Kienast, 2014; Liu, Hu, Li, & Yuan, 2018), to simple ‘benefit minus cost’ calculations (Wu et al., 2015; Xue et al., 2013). These approaches are generally only useful when comparing across commensurable values and at small scales.…”

Conceptual ambiguity hinders measurement and management of ecosystem disservices

The term ‘ecosystem disservices’ is used to refer to ecological costs that humans experience from nature. Managing ecosystems to protect ecosystem function and minimize costs to human well‐being is a global imperative. Like ecosystem services, disservices are outcomes of ecological processes and interactions. They are supplied concurrently with ecosystem services, not as isolated outcomes of ecosystem function. Therefore, accurate measurement of disservices must identify the ecological interactions contributing to the disservice, as well as any associated services. Despite regular calls for increased rigour around measuring services and disservices, conceptual and methodological ambiguities dominate the ecosystem disservices literature. A systematic literature review revealed 85 studies that aimed to explicitly identify or measure ecosystem disservices. Only 13 studies met both essential criteria for an empirical assessment of disservices: identification of the ecological interactions supplying the disservice and identification of associations between services and disservices. Most empirical studies identify ecosystem disservices based on subjective opinions or proxy data, and rarely acknowledge how disservices are related to services within the system. Some identify the presence of unwanted organisms, management costs, minor nuisances and personal aversions as ecosystem disservices. Synthesis and applications. Disservices are supplied concurrently with ecosystem services and human perceptions do not always accurately represent ecological costs in social–ecological systems. Hence, knowledge of the ecological interactions underlying perceived and actual disservices is vital for evidence‐informed decision‐making that sustains biodiversity and human well‐being.
