Data from: Proximity to roads, but not exposure to metal pollution, is associated with accelerated developmental telomere shortening in nestling great tits
<p><span><span><span><span><span><span><span><span><span><span><span>Comprehensively understanding the factors affecting physiology and fitness in urban wildlife requires concurrently considering multiple stressors. To this end, we simultaneously assessed how metal pollution and proximity to roads affect body condition and telomere shortening between days 8 and 15 of age in nestling great tits (<i>Parus major</i>), a common urban bird. We employed a repeated-measures sampling design to compare telomere shortening and body condition between nestlings from four urban study sites south of Antwerp, Belgium, which are located at different distances from a metal pollution point source. In addition, we explored associations between metal exposure and telomere dynamics on the individual level by measuring blood concentrations of five metals/metalloids, of which lead, copper and zinc were present at concentrations about the limit of detection. To assess whether roadway-associated stressors (e.g. noise and air pollution) might affect nestling condition and telomere shortening, we measured the proximity of nest boxes to roads. Metal exposure was not associated with nestling telomere length or body condition, despite elevated blood lead concentrations close to a metal pollution source (mean ± SE = 0.270 ± 0.095 µg/g wet weight at the most polluted study site), suggesting that nestlings may have some capacity to detoxify metals. However, nestlings from nest boxes near roads exhibited more telomere shortening between days 8 and 15 of age, and shorter telomeres at day 15. Nestlings in poorer condition also had shorter telomeres, but proximity to the road was unrelated to body condition. Thus, nutritional stress is unlikely to mediate the relationship between proximity to roads and telomere length. Rather, proximity to roads could have affected telomere shortening by exposing nestlings to air or noise pollution. Our study highlights that traffic-related pollution, which is implicated in human health problems, might also affect urban wildlife.</span></span></span></span></span></span></span></span></span></span></span></p>
Reciprocal transplantation of two ecotypes of two species along a metal pollution gradient
<p>This dataset consists of data collected during a field experiment that took place from the beginning of June to the end of September 2020, covering the entire growing season. This experiment was conducted in the former mining area of Sentein (department of Ariège, South West of France, 42°49'30.3 "N, 0°53'53.3 "E), located at 2000m altitude at the subalpine belt of the Pyrenees Mountains on a calcareous rock.</p> <p>This dataset contains "Block, Habitat, Species, Ecotype and Neighbouring" as explanatory categorical variables and "Target survival" as binomial response variable.</p> <p>This data was analyzed in order to understand the importance of species and ecotypes stress-tolerance in competitive and facilitative responses to neighbours along metal-pollution gradients, and to assess both the effect of neighbours at different stress levels and the effect of metallic stress with and without neighbours.</p>

Data from: Earthworms and cadmium – heavy metal resistant gut bacteria as indicators for heavy metal pollution in soils?
Preservation of the soil resources stability is of high importance for ecosystems, particularly in the current era of environmental change, which presents a severe pollution burden (e.g. by heavy metals) to soil fauna. Gut microbiomes are becoming recognized as important players in organism health, with comprehension of their perturbations in the polluted environment offering new insights into the nature and extent of heavy metal effects on the health of soil biota. Our aim was to investigate the effect of environmentally relevant heavy metal concentrations of cadmium (Cd) on the earthworm (Lumbricus terrestris) gut microbiota. Our results revealed that Cd exposure led to perturbations of earthworm gut microbiota with an increase in bacteria previously described as heavy metal resistant or able to bind heavy metals, revealing the potential of the earthworm-gut microbiota system in overcoming human-caused heavy metal pollution. Furthermore, an 'indicator species analysis' linked the bacterial genera Paenibacillus, Flavobacterium and Pseudomonas, with Cd treatment, suggesting these bacterial taxa as biomarkers of exposure in earthworms inhabiting Cd-stressed soils. The results of this study help to understand the impact of anthropogenic disturbance on soil fauna health and will have implications for environmental monitoring and protection of soil resources.
