Over the past five decades, human activities have resulted in the release of increasing amounts of carbon dioxide and other greenhouse gasses, contributing to global climate change through further warming of the atmosphere. The planet has warmed by around 0.85°C. This rise in temperature has been shown to significantly affect many organisms. In the context of climate change, it's not just a question of rising temperature, but also of various abnormal temperature fluctuations and, in some contexts, falling temperatures. In this particular experiment, we examined how temperature changes affect Folsomia candida springtails in their growth, reproduction and behavior. We selected adult individuals aged between 40 and 60 days. In total, we created twelve colonies, for three treatments and four colonies per treatment. These were: the optimal temperature, which we also took as a control group; the low-temperature treatment (10 °C); and a fluctuating one where temperature was randomly switched between the lower and the optimal ones. The results of the experiment showed that the F. candida springtails did indeed respond to temperature changes outside its optimal range. But responses are variable in the context of egg production, egg hatching and number of individuals. In colonies subjected to low temperatures, egg production was delayed. Overall, the low-temperature and random colonies showed no variation in mean individual size compared with the control colony. We found that temperature changes primarily affected egg production and hatching by delaying them, but also by reducing egg hatchability, most notably in cold temperatures (10°C) as well as random temperature colonies. Further studies are needed to examine the exact physiological and molecular reasons why hatching capacity and egg production are reduced at low temperatures and the specific adaptations that help springtails to deal with these changes.
