“…The presence of A. caliginosa had no added effect on bulk soil DEA despite its contribution to N 2 O emissions on day 21. The absence of a DEA effect has also been observed in the casts of the endogeic species Pontoscolex corethrurus (11). These observations suggest that although A. caliginosa increases the activity of denitrifiers and N 2 O emissions through gut passage (24,25), this effect may be negligible when considering the entire soil profile.…”

Earthworm activity is known to increase emissions of nitrous oxide (N 2 O) from arable soils. Earthworm gut, casts, and burrows have exhibited higher denitrification activities than the bulk soil, implicating priming of denitrifying organisms as a possible mechanism for this effect. Furthermore, the earthworm feeding strategy may drive N 2 O emissions, as it determines access to fresh organic matter for denitrification. Here, we determined whether interactions between earthworm feeding strategy and the soil denitrifier community can predict N 2 O emissions from the soil. We set up a 90-day mesocosm experiment in which 15 N-labeled maize (Zea mays L.) was either mixed in or applied on top of the soil in the presence or absence of the epigeic earthworm Lumbricus rubellus and/or the endogeic earthworm Aporrectodea caliginosa. We measured N 2 O fluxes and tested the bulk soil for denitrification enzyme activity and the abundance of 16S rRNA and denitrifier genes nirS and nosZ through real-time quantitative PCR. Compared to the control, L. rubellus increased denitrification enzyme activity and N 2 O emissions on days 21 and 90 (day 21, P ‫؍‬ 0.034 and P ‫؍‬ 0.002, respectively; day 90, P ‫؍‬ 0.001 and P ‫؍‬ 0.007, respectively), as well as cumulative N 2 O emissions (76%; P ‫؍‬ 0.014). A. caliginosa activity led to a transient increase of N 2 O emissions on days 8 to 18 of the experiment. Abundance of nosZ was significantly increased (100%) on day 90 in the treatment mixture containing L. rubellus alone. We conclude that L. rubellus increased cumulative N 2 O emissions by affecting denitrifier community activity via incorporation of fresh residue into the soil and supplying a steady, labile carbon source.

“…Organic matter mineralization and nutrient cycling. Earthworm activity via the production of casts is recognized as an important factor affecting C, N and phosphorus (P) cycles in the soil and CO 2 and N 2 O fluxes from the soil to the atmosphere (Chapuis-Lardy et al, 2010;Jiménez et al, 2003;Lavelle et al, 1998). The activity of such endogeic geophagous earthworms is often considered to increase C mineralization in the short term and favour C storage through the stabilization of SOM in stable micro-aggregates in the long term Lavelle and Martin, 1992;Lavelle and Spain, 2001).…”

A B S T R A C TExotic peregrine earthworms are often considered to cause environmental harm and to have a negative impact on native species, but, as ecosystem engineers, they enhance soil physical properties. Pontoscolex corethrurus is by far the most studied morphospecies and is also the most widespread in tropical areas. The term of morphospecies is used in this review because P. corethrurus may in fact constitute a complex of cryptic species. This earthworm is found in a wide range of habitats, from apparently pristine to any kind of human-disturbed environment. This review synthesizes 265 studies describing the distribution, morphology, biological and ecological traits of this morphospecies, as well as its impacts on soil conditions and communities. We then discuss the characteristics necessary for this specific morphospecies to become a successful colonizer throughout the world and the positive and negative effects it can have on the ecosystems that it has invaded. We emphasize the lack of knowledge of P. corethrurus reproductive mode and ploidy level, of its population genetics, and of the potential existence of cryptic species. To finish, we highlight the fact that data on P. corethrurus interactions with non-earthworm soil macrofauna are scarce.

“…The species formerly belonged in the Glossoscolecidae family, but was recently allocated to the Rhinodrilidae family by James (2012), following the phylogeny of James and Davidson (2012). It is also the most well-known earthworm species in the humid tropics, frequently used in ecological and agronomic studies (Bhattacharjee and Chaudhuri, 2002;Buch et al, 2013;Chapuis-Lardy et al, 2010;Dupont et al, 2012;Hamoui, 1991;Marichal et al, 2010). Being a geophagous endogeic species, P. corethrurus shows high plasticity regarding its tolerance to soil physicochemical characteristics, including variable moisture, high temperatures, exceptionally high carbon dioxide and low oxygen levels, and is capable of inhabiting nutrient-poor soils (Cunha et al, 2014;Hamoui, 1991;Lavelle et al, 1987), as well as rotten logs (Buch et al, 2011).…”

Abstract:Pontoscolex corethrurus (Müller, 1857) plays an important role in soil terrestrial ecosystems and has been widely used as an animal model for a large variety of ecological studies, in particular due to its common presence and generally high abundance in human-disturbed tropical soils. In this study we describe the complete mitochondrial genome of the peregrine earthworm Pontoscolex corethrurus. This is the first record of a mitochondrial genome within the Rhinodrilidae family. Its mitochondrial genome is 14 835 bp in length containing 37 genes (13 protein-coding genes (PCG), 2 rRNA genes and 22 tRNA genes). It has the same gene content and structure as in other sequenced earthworms, but unusual among invertebrates it has several overlapping open reading frames. All genes are encoded on the same strand, most of the PCGs use ATG as the start codon except for NAD3, which uses GTG as the start codon. The T+A content of the mitochondrial genome is 59.9% (31.9% A, 27.9% T, 14.9% G, and 25.3% for C). The annotated genome sequence has been deposited in GenBank under the accession number KT988053.
