Special Issue Information

Dear Colleagues,

Earthworms are ecosystem engineers that manipulate the biological, chemical, and physical attributes of the soil system with cascading ecosystem-wide effects. These effects are commonly regarded as having positive effects on the provisioning of ecosystem services. However, in cases where earthworms are introduced into earthworm-free ecosystems, their activities can negatively impact the soil system and the associated ecosystem commonly assessed by measures like intensity of erosion, soil biodiversity, and retention of carbon. In this Special Issue, I aim to curate papers that report on how earthworms affect soil properties or the ensuing ecological processes.

Papers are invited on the effect of earthworms on the soil system from regions where earthworms are endemic or exotic. Submissions could report, for example, on earthworm-related effects on soil structure from the aggregate to pedon scale, biogeochemical cycles, agricultural properties, the habitability of microhabitats, the composition of the soil community, or the evolution of greenhouse gases. Manuscripts that report on original research, literature surveys, and meta-analyses are welcome. However, works that shed light on how soil properties influence the assembly of earthworm communities or indeed the presence and absence of earthworms are also of interest.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Soil Systems is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Earthworms are ecosystem engineers that are sensitive to land-use intensification and edaphic conditions, yet their ecology remains poorly understood in transformed semi-arid landscapes. We hypothesized that, in recently colonized agroecosystems, land-use intensity and physicochemical soil conditions jointly filter the earthworm assembly. In the recently irrigated Lower Valley of the Negro River, Patagonia, Argentina, we sampled earthworms and soils across five land uses—riparian reference sites, fruit orchards, pastures, cereal crops, and horticulture plots—in landscapes dominated by Natrargid Ustolls and Fluventic Haplocambids. We found five species, all of which were exotic Lumbricidae, including the first Argentine record for Murchieona minuscula, indicating a recent colonization following human-mediated niche construction that created an ecological island. The earthworm abundance and biomass were highest in permanent and semi-permanent uses and were driven primarily by soil moisture, pH, and particulate organic matter. Crucially, our results reveal that land-use intensity filters communities by restricting the initial colonization rather than through local extinctions. These findings confirm that soil properties mediate the impact of land use on earthworm assemblages. The inclusion of pastures and fruit orchards in the rotations favors the earthworm populations that, despite low diversity, enhance soil functioning and contribute to agricultural sustainability in semi-arid irrigated agroecosystems.
