I am so happy to see this work published 🥳 @FWF_at @Mol_Ecol @uniinnsbruck #GlobalWarming #ClimateChange #AggressiveBehaviour
We investigate which factors potentially influence the aggressive behaviour in the high-elevation #ant Tetramorium alpestre.

In a correlative approach, we analysed the behaviour 😡 as well as genetic & environmental proxies of 47 colony fragments collected across the European Alps: Within- & across-colony genetic relatedness, cuticular hydrocarbons, body size, across-colony geographic distance, ...

... a) some environmental proxies & aggression differed among populations but not genetic proxies & b) air temperature & worker nitrogen-isotope values correlated positively with worker aggression😡.
We also found single- & multiple-queened colonies within the same population

Even though social structure varied between populations, the data show that environmental factors, rather than social structures, had an impact on this ant's aggressive behaviour. We infer that #GlobalChange affects aggression in this ant 🐜 and ...

... propose 5 mutually non-exclusive scenarios to explain the behavioural change mechanistically. We speculate that aggression may increase due to future increases in temperature & nitrogen availability in this #ant & other species living in high elevations. @STOTEN_journal
