“…The earthworms used within the experiment were translocated from a very moist environment (60% of gravimetric moisture content) into a soil with 40% moisture, and they lost weight in this second environment. Also, earthworms consume water for respiration, to produce mucus to avoid drying, and to move through the soil [15], so that the loss of weight is a physiological effect and not a response to an inhibitory condition [16]. Excluded the stress caused by the experimental conditions in weight loss because prolifi cacy was high.…”

“…Soil moisture attributed to rainfall event and dry spells significantly influenced abundance of L. terrestris and Isoptera. As soils become drier, L. terrestris particularly surface dweller and shallower burrower species, move into deeper soil horizons while Isoptera move to the surface and vice versa depending on moisture conditions ( Dibog et al., 1998 ; McDaniel et al., 2013 ; Yêyinou Loko et al., 2017 ). Furthermore, the combined effect of mulch reduction linked to decomposition and less rainfall as the season progressed led to increase in Isoptera from mid-season onwards.…”

The continued decline in both populations and diversity of soil macrofauna in agroecosystems remains a major concern for sustainable food production in Southern Africa. Macrofauna abundance and diversity were examined in a maize monocropping system following repeated incorporation of Calliandra calothyrsus , Crotalaria juncea , cattle manure, maize stover, and Pinus patula sawdust at 1.2 or 4.0 t C ha −1 with or without nitrogen (120 kg N ha −1 ) for 13 years (seasons). All treatments received phosphorus (P), potassium (K), and sulphur (S) at 16.0, 14.7 and 4.6 kg ha −1 , respectively, at each planting time in December. Using the ISO/TSBF (Tropical Soils Biology and Fertility Institute) monoliths procedure, macrofauna were collected to a depth of 0.30 m fortnightly from February to mid-May 2016. Lumbricus terrestris and Isoptera were significantly (P < 0.001) affected by organic treatment and seasonal time, while organic treatment alone significantly affected Elateridae. A fluctuating trend characterised Diplopoda, L. terrestris and Isoptera with two general peaks for L. terrestris and a significant Isoptera peak under maize stover. Rainfall significantly influenced L. terrestris and Isoptera abundance, while within-season sampling time explained the observed fluctuations in Diplopoda, Holotrichia serrata , Araneae, Acrididae, and Formicidae. While Araneae was prevalent under maize stover, Elateridae, H. serrata and Araneae showed no distinct pattern in abundance. At low application rate, higher Shannon-Wiener diversity indices were apparent except for maize stover. Increasing application rate of the different organics amplified stimulation, abundance and persistence of macrofauna, and significantly increased diversity relative to the control. Application of N-based mineral fertiliser appeared to be detrimental to selective macrofauna (e.g., L. terrestris, Isoptera and Elateridae). Monte Carlo permutation test identified ammonium nitrate as the most influential and detrimental variable followed by organic resource quality, soil organic carbon (SOC) and application rate. Long-term co-application of organic and inorganic resources thus stimulated macrofaunal populations and maintained diversity. To sustain the productivity of the predominantly maize-based smallholder cropping systems, it is proposed that extension packages promote the inclusion of a minimum of at least 1.2 t carbon ha −1 annually towards improved soil health.

“…By contrast, A. caliginosa caliginosa has been shown to be very resistant to dehydration and can survive the rapid loss of as much as 60% of the body water (Roots 1956). Moreover, this species survives drought by forming estivation chambers (McDaniel et al, 2013) deeper in the soil (10-20 cm) and by increasing its body fluid osmolality to maintain its water content (Bayley et al, 2010).…”

“…Endogeic earthworms, which make horizontal burrows through the soil, such as Aporrectodea caliginosa, are also very sensitive to drought conditions (Eggleton et al, 2009;Bayley et al, 2010). However, they are able to survive short periods of drought by burrowing to depths of 10-20 cm and forming an estivation chamber (Bayley et al, 2010;McDaniel et al, 2013), composed of mucus and gut content to protect against water loss. Similarly, some anecic earthworms, which make permanent vertical burrows in soil, can enter in a true diapause during a dry period and stay a few months in dormant stage (Jiménez and Decaëns, 2004).…”

Loss of plant diversity resulting from forecasted drought events is likely to alter soil functioning and affect earthworm communities. Plant-soil interactions are expected to play an important role in mediating climate change effects on soil decomposers. In this study, we test above-belowground linkages after drought by focusing on the effects of subordinate plant species on earthworm communities. Using a combination of subordinate species removal and experimental drought, we show that subordinate species, when present, increased in biomass after drought and induced an increase in total earthworm biomass. These effects were thought to be associated with the maintenance of food quantity and quality (e.g. nitrogen-rich litter) in relation to subordinate species. In support to this hypothesis, we found a positive correlation between the abundance of juvenile earthworms and plant community biomass hence litter quantity, and between the total biomass of earthworms and the abundance of subordinate species. Anecic earthworms were the most benefited by the presence of subordinate species under drought, especially Lumbricus terrestris, which was significantly correlated to the biomass of the nitrogen-rich subordinate species Veronica chamaedrys. Results of a multiple factor analysis (MFA) also highlighted positive associations between earthworm and subordinate species, independently of the drought treatment. Our study highlights how climate change, in this case reduced summer rainfall, can influence plant functional groups, with cascading effects on earthworms. It is therefore crucial, considering forecasted climate change, to understand these processes in order to better predict ecosystem responses and to adapt grassland management.
