a b s t r a c tLittle is known about the diversity and ecology of earthworms in floodplains, as well as their response to natural and anthropic perturbations (e.g. floods, river channelisation, floodplain restoration). We characterised the patterns of earthworm communities and species traits in the different habitats of a lowland restored floodplain in Switzerland. In addition to classical species-based metrics, such as species richness and Shannon diversity, species traits were used to calculate the community weighted means (CWMs) of traits and functional dispersion (FDis). We hypothesised that trait-based metrics would reveal clearer patterns than classical approaches. The distribution of earthworm traits varied among habitats in relation to changes in flooding frequency: poorly developed gravel bar soils most exposed to flooding were characterised by high abundance of small epigeic species and low abundance of large anecic species. Differences in anecic and endogeic earthworm community structure matched flood frequency. In agreement with our hypothesis, CWMs were more strongly correlated to environmental variables than species composition, diversity, or functional diversity. Based on these results, the ratio of the relative abundances of epigeic and anecic species, and the differences in species composition within anecic and endogeic ecological types of earthworms were identified as indicators of soil development in floodplains.

“…They can accumulate high levels of contaminants due to their feeding habits (Morgan and Morgan, 1998;Carpené et al, 2006;Hsu et al, 2006), as well as due to dermal exposure of their whole body (Lanno et al, 2004;Kamitani and Kaneko, 2007). The most commonly used earthworm species for biomonitoring is Eisenia fetida (Nahmani et al, 2007a), which is recommended for use in several international standard toxicity tests (OECD, 2004).…”

“…In addition to the fact that total content of contaminant in the soil is less important for risk assessment than its bioavailable amount (Nahmani et al, 2007a), the regulations also do not take into consideration the possibility of contaminant interactions, as well as the enhanced toxicity of complex mixtures of contaminants. Therefore, bioavailability and possible toxicity of multicontaminated soil could only be determined by exposure and effect assessment using various bioindicator organisms (Kamitani and Kaneko, 2007;Calisi et al, 2013).…”

Treated sewage sludge is commonly used in agriculture as fertilizer. It is, therefore, necessary to determine possible detrimental influences of sludge application on soil contamination and accumulation of contaminants in tissues of terrestrial animals, which in the long run could also have undesirable effects on humans. With that aim, the study was performed using earthworm Eisenia fetida as test organism and semi-solid depot sludge from wastewater treatment plant as exposure media. The concentrations of 26 metals/metalloids were determined in depot sludge, and their bioaccumulation was estimated in whole tissue of E. fetida, and for the first time in the soluble tissue fraction, which represents metal fraction available for metabolic requirements and toxic effects.Obtained results have revealed acceptable levels of several elements (Cd, Cr, Cu, Ni, Pb, Zn) in depot sludge, when compared to currently valid regulations, and only moderate accumulation of some elements (e.g. As, Ba, Cd, Co, Fe, Tl, V, and Zn) in earthworms, as a consequence of exposure to depot sludge. However, concentration increase after exposure to depot sludge was observed in E. fetida for several elements (Cd, Mo, and Zn), which were present in lower concentrations in the exposure mixtures than in soil. Contrary, concentration decrease was observed for Cs, Mn, and Rb, although they were present in higher concentrations in depot sludge than in soil. It was an indication of disturbance in metal homeostasis in earthworms, possibly caused by exposure to complex mixture of contaminants present in depot sludge. The cumulative effect of exposure to a number of various contaminants (inorganic, organic, microbiological and pharmaceutical), even if each of them was not present in very high concentrations, could have caused distress in earthworms exposed to depot sludge.

“…They can be sampled easily, have a wide distribution range and strongly accumulate pollutants. However, the accumulation of metals varies between ecological categories and species (jéGou et al, 2001;kaMitani & kaneko, 2004). Earthworms are important for bioturbation as they bring to the surface minerals and soil materials from lower soil horizons and are depositing them on the soil surface as earthworm casts (jorDan et al, 1997).…”

IntroductionSoils are the major sink for heavy metals released into the environment by anthropogenic activities; most metals released to the environment do not undergo microbial or chemical degradation, Earthworm casts as a sampling medium -a case study from highly contaminated Hg roasting site P�enk (Idrija area, Slovenia) AbstractIn this study an interesting sampling medium -earthworm casts was examined in a highly Hg contaminated area. Enrichment factor (EF) has been applied to assess elevated concentrations of analyzed elements in earthworm casts and to determine elevated concentrations of these elements in soils and casts with regard to European average concentrations in topsoil. In a previous study (TeR�i~ & gosaR, 2012) it was shown that Hg contents and dispersion in casts from studied roasting site are comparable to those in soil, which indicates that soil contamination is substantially reflected in contamination of earthworm casts. Therefore the comparison between elemental concentrations in earthworm casts and soil was investigated with the intention to assess the reflection of possible soil contamination in casts. Besides Hg contamination, elevated concentrations of As, Ca, Cd, Mo, Pb and U were also determined in earthworm casts. The calculated EFs show moderate enrichment of casts with Ca, Sr and P and minimal enrichment with Mg, Zn and Cu. Cast, SOM (surface organic matter rich soil layer) and soil enrichments with regard to the European averages show extreme enrichment of all studied media with Hg, followed by significant enrichment with Mo and Cd and moderate enrichment with As. Spatial distributions of analyzed elements in casts mostly show similar pattern as in soil, however, because of the different nature of different earthworm species and specific properties of different elements, the data about cast contamination can only serve as an approximate prediction about the dispersion and distribution of contaminant in soil. Izvle~ekNa mo~no obremenjenem okolju živosrebrne žgalnice v okolici Idrije smo raziskovali zanimiv vzor~ni medijdeževnikove iztrebke. Faktor obogatitve (EF) smo uporabili za oceno povi�anih vsebnosti analiziranih elementov v deževnikovih iztrebkih in tleh ter za primerjavo s povpre~nimi vsebnostmi v tleh Evrope. Predhodna (TeR�i~ & Gosar, 2012) in ta �tudija sta pokazali, da so Hg vsebnosti in prostorska porazdelitev v deževnikovih iztrebkih dobro primerljive z vsebnostmi in porazdelitvijo v tleh na raziskovanem ozemlju, kar kaže da se onesnaženje tal dobro odraža v vsebnostih v deževnikovih iztrebkih. Primerjavo med vsebnostmi kemijskih elementov v deževnikov iztrebkih in tleh smo raziskovali z namenom, da bi ocenili stopnjo ujemanja vsebnosti elementov v deževnikovih iztrebkih in tleh. Poleg povi�anega Hg smo dolo~ili tudi povi�ane koncentracije As, Ca, Cd, Mo, Pb in U v deževnikovih iztrebkih. Izra~unani faktorji obogatitve (EF) so pokazali zmerno obogatitev v iztrebkih z Ca, Sr in P ter rahlo obogatitev z Mg, Zn in Cu. Vsebnosti v deževnikovih iztrebkih, vrhnjem z organsko...
