“…International environmental policies claim for establishment of easy-to-use applicable tools to monitoring the conservation status of ecosystems and the impact of human actions on ecosystem viability and persistence (Sillero et al, 2021). In this sense, biomonitoring of health and performance of sentinel organisms has proven appropriate in many different types of assemblages, including bird communities (Baos et al, 2022;Plaza et al, 2018;Solgi et al, 2020). Different studies worldwide have shown that human activities generate toxic pollutants that alter the physiology of species (Giraudeau et al, 2018).…”

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.

“…Critical limits for lead and zinc in soils are 50 and 125–150 mg/kg, respectively. For cadmium, most non-contaminated soils have a concentration of less than 1 mg/kg, and its critical concentration in the soil is between 1.5 and 2.5 mg/kg [ 6 , 7 ]. Therefore, concentrations above this range may risk to the environment and human health.…”

“…With a more significant number of spectral bands, hyperspectral data allows for more detailed spectral analysis, enabling the differentiation of subtle variations in the spectral signatures of different materials, including heavy metals. This additional spectral information enhances the accuracy and reliability of heavy metal detection [ 7 ]. Hyperspectral data can effectively distinguish heavy metal signatures from other materials or noise in the soil by capturing fine spectral details and providing a comprehensive spectral analysis.…”

As a result, hyperspectral data is precious for assessing and monitoring heavy metal contamination in soil supporting environmental management and remediation efforts [ 7 ].…”

Multiple studies have shown that exposure to pollutants can increase genotoxic damage in different taxa. However, to our knowledge, the effects of environmental stress have been explored little. In certain stressful ecosystems, such as seasonally dry tropical forests, the combined effects of anthropogenic activities and ongoing global changes can cause an increase in environmental stresses, in turn, may trigger physiological and genetic effects on biodiversity. The present aims to assess changes in the prevalence of genotoxic damage in birds within three states of forest degradation in the Tumbesian Region of Western Ecuador. We used blood samples from 50 bird species to determine the frequency of micronucleus and nuclear abnormalities in erythrocytes. Our results revealed a significant impact of forest degradation on the occurrence probability of micronucleus and nuclear abnormalities at the community level. Localities with higher levels of degradation exhibited higher levels of abnormalities. However, when analyzing the dominant species, we found contrasting responses. While 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 for semi‐natural and shrub‐dominated respectively. We concluded that the degradation process of these tropical forests increases the stress of bird community generating genotoxic damage. Bird responses seem to be species‐specific, which could explain the differences in changes in bird composition reported in other studies.
