“…Potential distribution modeling/niche characterization [ 30 , 31 , 32 ] and genetic diversity monitoring [ 33 ] have been established as important tools for evaluating the conservation status of vertebrates. Ecological niche modeling has been used successfully on earthworms; in spite of their peculiarities (difficulty of sampling, patchy distributions), MaxEnt [ 34 , 35 , 36 , 37 ], Random Forests [ 38 ], and other algorithms have achieved high predictive power when using large-scale variables to predict the earthworms’ potential distribution. Implementing these approaches to earthworm biodiversity conservation would facilitate the necessary research on this key component of soil fauna.…”

In spite of the high conservation value of soil fauna, the evaluation of their conservation status has usually been neglected. This is more evident for earthworms, one of the most important ecosystem service providers in temperate habitats but rarely the subject of conservation research. These studies have not been developed in Western Europe, which comprises high diversity and several early-branching, relic genera. One potentially menaced representative of this fauna is Compostelandrilus cyaneus; this risk can be assessed by implementing potential distribution modeling and genetic diversity monitoring to their known populations. Genetic barcoding was performed in representatives of four populations (three of them newly sampled) in order to estimate genetic diversity and population genetics parameters. Ensemble species distribution models were built by combining several algorithms and using the five more relevant bioclimatic and soil variables as predictors. A large amount of genetic diversity was found in a small area of less than 20 km2, with populations located in less managed, better-preserved habitats showing higher genetic variability than populations isolated from natural habitats and surrounded by anthropic habitats. Potential distribution appears to be strongly restricted at a regional scale, and suitable habitats within the extent of occurrence appear fragmented and relatively limited. In addition, the main variables determining the ecological niche of C. cyaneus suggests a vulnerability to climate change and increasing soil compaction. Based on this knowledge, this species was assessed as Critically Endangered following the IUCN Red List of Threatened Species criteria, and some potential conservation actions are suggested.

The historical biogeography of the Lumbricidae, the main Palearctic earthworm family, may be linked to the paleogeography of their putative ancestral range in Iberia–southeastern France–Corsica–Sardinia. Although molecular phylogenetics has recently been used to analyze most endemic genera in this area, the genus Kritodrilus has not yet been studied. The generotype Kritodrilus calarensis and other closely related species inhabit southeastern France. However, other species from the Iberian Peninsula (e.g., Kr. osellai) have been assigned to Kritodrilus, the same for the Vindobonic (Hungarian–Austrian–Czech–Slovakian) Dendrobaena mrazeki. In order to unravel the paleobiogeographic, evolutionary, and taxonomic significance of Kritodrilus, the aforementioned species (and three potential relatives) were sequenced for seven molecular markers. Molecular phylogenetic inference recovered a clade of French Kritodrilus (including Et. setusmontanus) closely related to the Northwestern Iberian Galiciandrilus and Compostelandrilus, the latter being a sister clade to the Vindobonic species (described as a new genus). Time‐calibrated phylogenetic inference estimated that these three clades diverged around 55 Ma. Ecological niche models for these clades were mainly influenced by the same environmental variables, but showed non‐overlapping highly suitable areas (except for Kritodrilus). Ancestral area reconstruction inferred the origin of the Lumbricidae in Corsica–Sardinia and the Iberian Peninsula, with eventual expansion eastwards toward France, Central Europe, and the Carpato‐Balkanic area. For Kritodrilus and its relatives, this expansion may have been contemporaneous with the Paleocene–Eocene thermal maximum. Later climatic changes may explain the strikingly disjunct ranges. This work highlights the evolutionary and biogeographic significance of these isolated earthworm lineages and the importance of their preservation.

“…According to the theory of ecological niche, each individual or taxon has its own spatial position and function within a community [39]. Therefore, the higher evenness of the soil mesofauna reflects an equilibrium in the coexistence of species, on which the balance and stability of ecosystem functioning are based [40,41].…”

Soil faunal communities play key roles in maintaining soil nutrient cycling. Affected by different land-use types, soil environment and soil faunal communities change significantly. However, few studies have focused on the aforementioned observations in coastal zones, which provide suitable habitats for many species of concern. Here, we investigated the changes in soil mesofaunal communities under different land-use types, including cotton fields, jujube trees, ash trees, a saline meadow, and wetlands. The variations in land-use types affected the community composition and diversity of soil mesofauna in the coastal zones. The taxa of soil mesofauna had different responses to land-use types in the coastal zones. Isotomidae was regarded as an indicator taxon of the coastal cropland regions. Entomobryidae was considered to be an indicator taxon of coastal artificial trees. Meanwhile, Onychiuridae and three taxa (Brachycera, Armadillidiidae, and Gammaridae) were indicator taxa of the coastal terrestrial ecosystem and the coastal wetland ecosystem, respectively. Thus, we suggested that specific soil mesofaunal taxa were considered to be appropriate bioindicators for land-use types in the coastal zones. The results of this study were helpful to develop guidelines for coastal biodiversity and ecosystem conservation in the future.
