“…Nuclear abnormalities to be considered as precursors of micronuclei was suggested by Walia et al (2013). Guner and Muranh (2011) reported differences in the erythrocyte micronucleus frequencies to be related to cell kinetics and replacement. They explained that individual and combination exposure of fishes to heavy metals led to an accumulation in the body but this accumulation did not assure an increase in MN frequency in peripheral blood erythrocytes.…”

The present study was aimed to evaluate genotoxicity in peripheral erythrocytes of Labeo rohita reared in two lakes viz., Vengaiah lake -sewage polluted (Lake A) and Yellamallappa Chetty lake -industrially polluted (Lake B) of Bangalore. To assess the micronuclei and nuclear abnormalities in such erythrocytes, blood samples were collected from heart of the freshwater fish, L. rohita anesthetized by MS222. The results were compared with the fish reared in the Hebbal fish farm (Control). The data revealed significantly high frequencies of erythrocytic abnormalities including nuclear as well as cytoplasmic in the fish blood sampled from lake B when compared to those of lake A. Such abnormalities in erythrocytes of fish varied seasonally also with summer exhibiting maximum deformities which can be attributed to the presence of genotoxic pollutants in the selected water bodies. The values were statistically significant at P<0.0001.

“…As far as nuclear abnormalities are concerned, the mechanism responsible for their formation is not fully understood. These abnormalities may complement the scoring of micronuclei (Güner & Muranli, 2011). It has been reported that nuclear abnormalities, as a defense response to prevent major detrimental effects, such as double chain breakage and generation of additional damage to the organism, are generated before micronuclei formation (Frixione & Rodríguez-Estrella, 2020).…”

Environmental stress as a consequence of anthropic pressures can affect the physiological condition of animals and cause damage to their DNA. Multiple studies have shown genotoxic effects of different pollutants; however, to our knowledge, the impact of environmental stress on genetic damage has been scarce explored. In some stressful ecosystems, such as seasonally dry tropical forests, the combined effects of anthropogenic activities and ongoing global changes cause increased environmental stresses that could trigger physiological and genetic effects on biodiversity. In this study, we evaluated the changes in the prevalence of genotoxic damage to birds in three states of forest degradation in the Tumbesian Region of Western Ecuador. We used the blood samples of 52 bird species to determine the frequency of micronucleus and nuclear abnormalities in the erythrocytes. Our results showed a significant effect of forest degradation in the proportion of micronucleus and nuclear abnormalities at the community level, localities with higher degradation showed higher levels of abnormalities. However, when analyzing the dominant species, we found contrasting responses. While Amazilis amazilia and Lepidocolaptes souleyetii showed a reduction in the proportion of nuclear abnormalities from the natural to shrub-dominated localities, Troglodytes aedon and Polioptila plumbea showed an increase. We concluded that the degradation process of these tropical forests increases the stress on the bird community generating genotoxic damage to the bird community. Bird responses seem species-specific, which could explain the differences in changes in bird composition reported in other studies.

“…Here, we investigated erythrocytic nuclear abnormalities between two stations and found reniform and lobed nuclei. These abnormalities might be impacts of environmental problems, such as heavy metal toxicity (such as copper and cadmium) ( Guner et al . 2011 ; Kousar & Javed 2015 ) and genotoxic damage ( Kousar & Javed 2015 ; Summak et al .…”

Hematological evaluation of fish is essential to the assessment of their physiological status. This study describes the morphometric analysis and comparison of blood cell characteristics in Zanarchopterus sp., Gerres filamentosus Cuvier, 1829 and Leiognathus decorus (De Vis, 1884). The species were collected at two locations off the coast of Trang Province, Thailand. A comparative hematological evaluation was made to assess the effects of environmental conditions on the blood of the fish. Ten individuals of each species were collected from a seagrass bed at Libong Island, where human activities are increasing, and from a secluded sandy beach. Their blood samples were analysed using the blood smear technique. Erythrocytes of all the studied fishes were either elliptical or oval. The morphometric data from both locations showed that erythrocytes were of similar size, except for those of Zanarchopterus sp. Fish from both stations showed several types of leukocytes, including neutrophils and lymphocytes.The highest proportion of leukocytes was made up of lymphocytes, followed by neutrophils. However, monocytes were only observed in fish from Libong Island and the erythrocytic nuclei of fish collected from Libong Island were both reniform and lobate. Our results show the potential of hematological evaluation as an early warning signal of environmental impacts on aquatic animals. The determination of baseline parameters could provide a tool for the monitoring of environmental quality.
