“…Warmer temperatures during winter could increase the chances of survival of overwintering invertebrates (e.g., Bale & Hayward, 2010;Bradshaw & Holzapfel, 2010;Templer et al, 2012, but see also e.g., Sorvari et al, 2011, Haatanen et al, 2015. However, climate change will probably not only affect temperature during winter, but is also likely to result in a reduction in the depth and duration of snow cover (Christensen et al, 2013;Convey …”

“…In our study, mean winter temperature in 2019/2020 was 8.1 °C in Paris city and 6.9 °C in Chantilly forest (infoclimat data, (accessed on 4 December 2020)), higher than in 2017/2018 (city 6.2 °C, forest 4.7 °C) and 2018/2019 (city 6.3 °C, forest 5.2 °C) and higher than in the laboratory common garden environment (4 °C for both habitats). Cold winters could favor the strongest individuals, as suggested by Haatenen et al [ 25 ]. Therefore, toxicological assays may have been performed on colonies in poor condition.…”

“…For example, warmer winter increases mortality rate in insects such as the rose-gallin wasp Dilopepsis spinosa [ 41 ] or the boreal ant Formica aquilonia [ 26 ], probably because of higher metabolic rate that depletes fat reserves. On the other hand, some species seem to perform better under warm temperature, such as the ant Lasius niger , for which workers have lower mortality rate at warm temperatures [ 25 ]. In our study, mean winter temperature in 2019/2020 was 8.1 °C in Paris city and 6.9 °C in Chantilly forest (infoclimat data, (accessed on 4 December 2020)), higher than in 2017/2018 (city 6.2 °C, forest 4.7 °C) and 2018/2019 (city 6.3 °C, forest 5.2 °C) and higher than in the laboratory common garden environment (4 °C for both habitats).…”

Hibernation Conditions Contribute to the Differential Resistance to Cadmium between Urban and Forest Ant Colonies

Trace metals such as cadmium are found in high concentrations in urban environments. Animal and plant populations living in heavily contaminated environments could adapt to trace metals exposure. A recent study shows that urban populations of the acorn ant Temnothorax nylanderi are more resistant to cadmium than their forest counterparts. However, this study was performed using field colonies that had just come out of hibernation. Because urban and forest hibernation environments differ, the differential resistance to trace metals may originate either from differential hibernation conditions or from a different resistance baseline to cadmium. In this study, we tested these two hypotheses using laboratory common garden hibernation conditions. We let urban and forest colonies of the ant T. nylanderi hibernate under the same laboratory conditions for four months. After this hibernation period, we also collected field-hibernating colonies and we compared cadmium resistance between urban and forest colonies depending on the hibernation condition. We found a differential response to cadmium under common garden, with urban colonies displaying less larval mortality and lower size reduction of the produced individuals. This suggests a different resistance baseline of urban colonies to cadmium. However, unexpectedly, we did not detect the differential response between urban and forest colonies in the field, suggesting a more complex scenario involving both genetic and environmental influences.

“…In the case of insects, which are exposed to low temperatures during winter, the anticipated increase in temperatures ensuing from global climate change should enhance their chances of survival (Bale & Hayward 2010, Bradshaw & Holzapfel 2010, but see also e.g. Sorvari et al 2011, Haatanen et al 2015, although contrary effects should be expected as a consequence of snow cover reduction (Leather et al 1995, Bale & Hayward 2010.…”

Unexpected high overwintering survival rate of the cavity-dwelling ant <i>Temnothorax crassispinus</i> (Hymenoptera: Formicidae)

The mortality rate of many invertebrates is high during winter. The survival rate of the ant Temnothorax crassispinus , which overwinters above ground, was investigated. Unlike previous studies, this one showed a high survival rate during winter. In the field experiment, the number of workers at the end of the experiment amounted to 86-120% of the initial numbers, and 73 out of 74 queens survived. The high survival rate was most likely a result of the favourable weather conditions. In the laboratory experiment, none of the workers exposed to -24 °C survived, while the survival rate of workers kept in 5 °C was higher (73.2% on average) than those in 0°C (53.2%). The expected rise in temperatures as a consequence of climate change may result in a higher survival rate in the winter season, but also in the reduction of snow cover, which may exert the opposite effect.
