“…The slight increase in active CaCO 3 found in EW and P + EW treatments indicates that earthworms might ingest Ca 2+ and/or CaCO 3 from the bulk soil, produce calcium carbonate granules and incorporate them into the soil aggregates. Similar results have already been reported in Canti (2009) and Garcia-Montero et al (2013). The reasons for the excretion of calcium carbonate have not been clarified, so far.…”

“…Soil pH in treatment AR and BR was significantly lower than that in the control, indicating that A. robustus could significantly reduce soil pH. García-Montero et al (2013) found that earthworms (Prosellodrilus sp.) increase soil pH by their cast production and activity, which is quite different from our results.…”

The study aims to investigate effect of earthworm activity on metal bioavailability in soils using their BSAF-metals. Based on a microcosmic laboratory experiment, epigeic species Amynthas corticis (A. corticis) and endogeic species Amynthas robustus (A. robustus) were cultured in two types of soils contaminated by Cd, Zn, Pb and Cu for 120 days. Earthworm characteristics (i.e. numbers, biomass and BSAF), soil properties (i.e. pH, organic C and N contents along with their components such as mineralization and microbial masses) and DTPA extracted metals in soil were determined. After the incubation, the biomass and survival numbers of both earthworm species decreased significantly (P < 0.05). The accumulation of Cd, Zn and Pb in earthworm tissues and BSAF-metals were earthworm species dependent. According to two-way ANOVA, BSAF-Pb clearly showed the effect of different species of earthworms while BSAF-Cu indicated an interactive effect of earthworms and soil type. Earthworms changed soil properties significantly, especially for mineralized C (C min), dissolved N (N dis) and pH (P < 0.05). Earthworm activity increase DTPA extracted Zn and Cu, and the effect of A. robustus were stronger than for A. corticis. Redundancy analysis (RDA) showed that BSAF-Cu and BSAF-Pb contributed for respectively 51.9% and 51.7% of soil properties and DTPA metal changes, indicating that the effects of BSAF-Cu and BSAF-Pb on soil properties and on metal bioavailability in soil were similar. BSAF-Cu, indicating the interactive effect of earthworms and soil, accounted for 38.5% and 45.1% of soil properties and soil metal bioavailability changes. BSAF-Pb, representing the effect of earthworm species, accounted for 13.3% and 6.6% of soil property and soil metal bioavailability variations. Stepwise regression indicated that earthworm might change soil properties through their activities and interactions with soil, and hence increase heavy metal bioavailability. It suggested that BSAF is an important indicator for evaluating the effect of earthworm activity on soil metal bioavailability and designing remediation strategies.

“…These findings and others [59] may also explain the positive correlation found between TOC and Ca in the earthworm castings within this study. Positive correlations between the [63] showed in laboratory experiments that the origin of the C from CaCO 3 granules produced by the calciferous glands of L. terrestris is the dietary intake (litter) and only partially the atmospheric CO 2 and the ingested soil. Regardless the origin source of C, these authors stated that lumbricid earthworms really synthesize calcium carbonate and not just recycle the ingested material [61,63].…”

Regardless the origin source of C, these authors stated that lumbricid earthworms really synthesize calcium carbonate and not just recycle the ingested material [61,63]. Because relations of dependency between chemical elements constituting earthworm casts in a natural phase have been rarely studied, it is hard, without subsequent researches, to explain the correlations pH-TOC and TOC-Ca found in this study, and particularly if these correlations respect findings widely acknowledged in the case of soils, like the significant influences of soil pH on TOC contents as regulator, among others, of the nutrient bioavailability and organic matter turnover, cation exchange capacity, biological processes, or newly discovered (for example, the high concentration of SiO 2 in agricultural soils of North-Central Europe is highly correlated to co-existence of low TOC and low pH values in these soils [64])…”

This paper aimed to establish the species diversity of earthworms (Oligochaeta: Lumbricidae) and the chemical composition of earthworm surface castings within an urban park from west side of Romania (Timişoara City): Plevnei Park (45°44'58''N, 21°13'38''E). Eight lumbricid earthworm species have been identified: Lumbricus terrestris, Aporrectodea rosea, Aporrectodea longa, Aporrectodea caliginosa, Allolobophora chlorotica, Dendrobaena veneta, Dendrobaena octaedra, Dendrodrilus rubidus. Based on species incidence, several ecological indicators have been calculated: the constancy of earthworm species in the sampling areas, the Sørensen similarity of sampling points as species composition, and the Jaccard similarity (coenotic affinity) of the earthworm species within the sampled points. The surface castings have been analyzed for the following physical-chemical parameters: pH, total organic carbon (TOC), total nitrogen (N), plant available phosphorus (P), plant available potassium (K), and calcium water soluble (Ca). Because it is not yet clearly elucidated the casting behavior (surface or subsurface) of earthworms, and their feeding behavior, habitat behavior and casting behavior are not always clearly separated traits, and because until now it is insufficiently known how the environmental conditions affect the surface or subsurface casts production in earthworms, or how these conditions determine more than a single casting behavior for one species, there had been difficult to conclude which of the found species is responsible for the surface casting within the studied urban park. To find possible correlations existing between the physical-chemical parameters of the earthworm castings, Pearson, Spearman, and Kendall correlations (p<0.05) were calculated. The study revealed significant
