Earthworms are known to be farmer's friend due to its major role in maintaining the soil integrity and its fertility. Earthworm has greater diversity throughout world, specifically in tropical and temperate regions. Lumbricidae is the one of the most important family of earthworms due to its beneficial impacts to the mankind. Because a very less information is available about the diversity patterns of Lumbricidae family in India, hence an effort is made to record the species richness and distribution patterns of Lumbricidae earthworms from different regions of India. The present study is conducted to record the past and existing fauna of earthworms (Lumbricidae) from different states of India.

“…The collected earthworm samples were thoroughly washed to remove soil debris and preserved in 5% formalin to avoid color loss, as color is an important criterion for earthworm species identification. The earthworms were identified to the species level with the help of keys provided by [20][21][22][23][24][25][26][27][28]. Reasonable amounts of soil were taken from the place where earthworms were handsorted in plastic bags and were labeled with the site name and the date of sampling.…”

The population status and biomass of earthworms were studied in three different land use systems of pasture (Pa), silvopasture (SP), and mixed evergreen forest (MEF) from 2019–2020 in the Solan district of Himachal Pradesh, India. The aim of this study was to assess the population status of earthworms and investigate how different land use systems influence their abundance, diversity, and biomass. Earthworms and soil were sampled using the Tropical Soil Biology and Fertility (TSBF) method in all seasons (winter, spring, summer, monsoon, and autumn). The physicochemical properties of the soil were analyzed to evaluate their effects on the diversity, biomass, and density of animals. The diversity status parameters, such as the Shannon diversity index (H′), Margalef richness index (R), evenness (J′), and dominance index (D), were computed. A total of seven earthworm species, belonging to four families, namely, Amynthas corticis, Aporrectodea rosea, Drawida japonica, Eisenia fetida, Metaphire birmanica, Metaphire houlleti, and Lennogaster pusillus, were identified from all three land use systems. The lowest Shannon diversity index (H′), Margalef index (R), and evenness (J′) index values were registered in MEF (H′ = 0.661, R = 0.762, J′ = 0.369) compared to those in Pa (H′ = 1.25, R = 1.165, J′ = 0.696) and SP (H′ = 0.99, R = 0.883, J′ = 0.552), implying that MEF is the least diversified land system. In contrast, the highest dominance index (D) value was registered in MEF (Pa = 0.39, SP = 0.53, MEF = 0.67), which again showed that MEF is the least diversified land system. The highest values of abundance and biomass were recorded in MEF (754.15 individuals m−2 and 156.02 g m−2), followed by SP (306.13 individuals m−2 and 124.84 g m−2) and Pa (77.87 individuals m−2 and 31.82 g m−2). Both the density and biomass of earthworms increased from Pa to MEF (Pa < SP < MEF). This study is novel because it revealed that the diversity and productivity (biomass and abundance) values of earthworms were negatively correlated (as diversity increased, productivity decreased; as diversity decreased, productivity increased). The total values of abundance and biomass of earthworms in the three land use systems indicated perfect synchrony between aboveground and belowground habitats, whereas the diversity values revealed that MEF was dominated by one or two species and the least diversified. Therefore, for sustainable belowground productivity, aboveground conservation is recommended, and vice versa, regardless of diversity.

“…Apart from the endemic, a number of alien ambulant earthworm species have been discovered, which are now common in degraded ecosystems as a result of deforestation and intensive farming [18]. Indian earthworms are divided into three groups based on endemicity and dispersal: i) endemic or native species that are restricted to India; ii) exotic peregrine species that originated in other bio geographical regions; and iii) native peregrine species that evolved in India and now have widespread distribution in India and other bio geographical regions [19]. Hence it becomes necessary to adopt the DNA-based identification system as a valuable tool for identifying earthworm species and their physio chemical habitat.…”

Earthworms are considered as biological indicators of soil fertility and are the major macro fauna of soil. DNA tags are done to identify individuals belonging to the same species, as well as to distinguish between individuals from different species. In the present work, the earthworm fauna was investigated from three Taluks namely, Somvarpet, Virajpet and Madikeri of Coorg, a district situated in the south western part of Karnataka, India. This is the first scientific report on the earthworm species of Coorg and the physio-chemical properties of their soil. The physio-chemical characteristics of the soil were examined and DNA barcoding technology was used to identify the taxonomic status of earthworms. A total of 38 earthworm samples were collected, 30 of which were amplified using mitochondrial Cytochrome Oxidase subunit1 (CO1) gene specific primers. The sequencing data were deposited into Genbank and assigned to accession numbers (30 Accessions). The maximum likelihood technique was used to create the phylogenetic tree. Kimura's two-parameter model was used to calculate pairwise genetic distance. DNA barcoding results showed that Pontoscolex corethrurus was the most common earthworm species in Coorg. Progizzardus varadiamensis, Glyphidrilus annandalei, Amythas sp., Metaphire megascolidioides, Dichogaster bolaui and Acanthodrilidae sp were also observed. From the findings, it is observed that the mean pH of Coorg soil was found to be 6.2 with an electrical conductivity of 0.28 dS/m. Coorg soil contains a moderate level of Organic Carbon (O.C) content with an average of 1.74%. Thus, the study included extensive descriptions of earthworm species, as well as their DNA barcodes and the physio-chemical characteristics of their habitat, which help with future species identification.
