“…This clearly illustrates the anthropogenic pressure on earthworm communities in arable lands [90]. Similar report from Ivory Coast is available on the impact of land-use changes and landuse intensification on earthworm populations and diversity in intermediate-disturbed systems [91]. Even though these studies suggest the use of earthworms as bioindicators of man-made changes, it necessitates more field and laboratory investigations to find out earthworm community structure, species interrelations, and the most efficient species to be used in biomonitoring of ecosystem degradation due to anthropogenic activities in the forest areas.…”

The paper highlights the research carried out by different scientists in India on aspects of earthworm population dynamics and species diversity, associated with other soil fauna and microflora. It also deals with the importance of earthworm activity on physicochemical properties of soil with reference to India and other tropical countries. Stress is laid on the earthworm plant association and importance of the secretions of earthworms as plant growth stimulators. Moreover, the earthworm species reported and being utilized for vermicomposting in India are discussed, since vermicomposting is the ultimate technology which renders for the improvement of soil fertility status and plant growth. Earthworms serve as indicators of soil status such as the level of contamination of pollutants: agrochemicals, heavy metals, toxic substances, and industrial effluents; human-induced activities: land-management practices and forest degradation. In all these fields there is lacuna with respect to contributions from India when compared to the available information from other tropical countries. There is lot of scope in the field of research on earthworms to unravel the importance of these major soil macrofauna from holistic ecological studies to the molecular level.

“…Earthworms E. fetida are efficient species for bio-monitoring programs targeted at prevention of degradation of ecosystem due to anthropogenic activities (Tondoh et al, 2007). They can survive in highly contaminated environments due to their cell efflux of xenobiotics mediated by transporter proteins and detoxification enzymes.…”

Relating the treated wastewater quality and its impact on organismic biosensors (Prussian carp, Carassius gibelio and earthworm, Eisenia fetida) was the main objective of the study. The impact on health status of fish living downstream, microbiological contamination and antimicrobial resistance, fish tissue structure, blood biochemistry, oxidative stress, genotoxic effects, as well as multixenobiotic resistance mechanism (MXR) was assessed. Treated wastewater discharged from the WWTP modified the environmental parameters and xenobiotic concentrations of the receiving surface waters. Potential bacterial pathogens from fish and respective waters were found in relatively low numbers, although they comprised aeromonads with a zoonotic potential. High resistance profiles were determined towards the tested antimicrobial compounds, mostly sulfamethoxazole and erytrhomycin. Histopathology primarily revealed gill lamellar fusion and reduction of interlamellar spaces of effluent fish. A significant increase in plasma values of urea, total proteins, albumins and triglycerides and a significant decrease in the activity of plasma superoxide dismutase were noted in carp from the effluent-receiving canal. Micronucleus test did not reveal significant differences between the examined groups, but a higher frequency of erythrocyte nuclear abnormalities was found in fish sampled from the effluent-receiving canal. Earthworms indicated to the presence of MXR inhibitors in water and sludge samples, thus proving as a sensitive sentinel organism for environmental pollutants. The integrative approach of this study could serve as a guiding principle in conducting evaluations of the aquatic habitat health in complex bio-monitoring studies.Response to Reviewers: The response is attached as a separate file. We request that this manuscript be considered for publication in Science of the Total Environment as an original, full paper. This manuscript has not been published and is not under consideration for publication in any other journal. All authors concur with the submission.The manuscript is a result of a comprehensive study which integrated various disciplines and research fields. The authors decided to present it as a whole rather than splitting it in two or more papers, for a better understanding of the discussed subject. We believe we have presented a potential guiding principle for conducting evaluations of the aquatic habitat health in complex bio-monitoring studies.I will be serving as the corresponding author for the manuscript. We hope that it is found to be interesting and appropriate for publication in Science of the Total Environment. Should you have any questions, please do not hesitate to contact me.Yours truly, Natalija Topic Popovic, DVM, PhD Response: Thank you for this clarification. We have taken a whole different approach and completely rewritten all sections relating to the PCA as they were indeed confusing, and created a new biplot for plasma parameters. We hope that the new text, as inserted in the respect...

“…The change of soil structure into granular shape is due to earthworms, who also crush plant debris, change its positioning and push forward organic matter parts enhancing formation of aggregates so that it can be considerably influences organic matter dynamics and soil chemical properties (Ladd et al 1993). Based on multiple regression analysis, Tondoh et al (2007) found that OC and soil pH were potential criteria for changes in earthworm abundance. Earthworms respond to soil degradation -equally to soil physical and chemical changes (Linden et al 1994).…”

“…Among soil organisms, earthworms are the most commonly occurring invertebrates (Tondoh et al 2007). Earthworms enhance soil fertility and productivity through increasing availability of mineral nutrients to plants (Brady and Weil 2008) and improving the dynamics of soil organic matter (Reich et al 2005).…”

There has been observed widespread destruction of natural ecosystems around the world due to population growth, land use change and clear cutting which have affected soil properties. Different management strategies have been so far implemented to reduce this crisis in various regions of the world, such as e.g. short-term and long-term conservation management in the Zagros region. However, any management approach should be evaluated with appropriate measures to determine how managed areas respond. The main objective of the present study was to evaluate the potential of earthworms as an indicator for different forest management strategies and human disturbances in Zagros oak (Quercus persica Jaub. and Spach) forest. The sites selected included undisturbed one as the control (Un), the sites under five-year conservation management (FCM) and twenty-year conservation management (TCM) as well as the disturbed site (D). The results of principal component analysis (PCA) showed that different regions separated into the components: PC1 and PC2. Un and TCM sites gathered together and represented higher values of the factors such as pH, K available , OC, clay content, P available , CEC, overstory tree canopy, N tot , biomass and abundance of earthworms. The positive direction of the first axis reflected a gradient of EC, BD and P tot . According to the logistic model, NH 4 -N and EC played the most important role in earthworm presence and absence in Zagros forest ecosystem. Earthworm abundance and biomass could be a good indicator to evaluate different forest management strategies in the study area.
