A study conducted by researchers at the University of Bayreuth has shown that family interactions can help young beetles deal with the stress caused by climate change. Published in the journal Functional Ecology, the research explored how social interactions among family members might help reduce the negative effects of environmental stress. As global temperatures rise and extreme weather events like heat waves, cold snaps, floods, and droughts become more common, many biological systems face increasing pressure. These changes can affect animal behavior, fertility, and the survival of offspring. It is already known that parental care in animals can help protect offspring from environmental stressors like extreme temperatures. In this new study, the researchers wanted to know if interactions among siblings could also help young animals cope with climate-related challenges. To test this, they studied burying beetles, specifically the species Nicrophorus vespilloides. These beetles are known for their unique behavior of burying small animal carcasses to feed their young. In the study, the researchers created different environmental conditions to simulate cold stress and heat waves. In another part of the experiment, they altered soil moisture levels to mimic drought or flooding. In each setup, the beetle larvae were raised under three different conditions: with both siblings and parents, with siblings only, or completely isolated from siblings and parents. The researchers then observed the growth and survival of the larvae until they reached the pupation stage. The results showed that parental care consistently helped improve the growth and survival of the larvae. While interactions among siblings also had some benefits, these were not as reliable and depended on specific environmental and social conditions. For example, the negative effects of low temperatures were reduced when both siblings and parents were present. However, under high temperatures, the combined presence of siblings and parents actually became a disadvantage. One possible reason for this is increased competition among the larvae, which may be linked to the growth of microbes on the decaying food they eat. The study highlights that while social interactions can help animals cope with climate challenges, their effectiveness depends on the specific environmental and social context.
