Toxicity and the utilization of venom are essential features in the ecology of many animal species and have been hypothesized to be important factors contributing to the assembly of communities through competitive interactions. Ants of the genus Monomorium utilize a variety of venom compositions, which have been reported to give them a competitive advantage. Here, we investigate two pairs of Monomorium species, which differ in the structural compositions of their venom and their co-occurrence patterns with the invasive Argentine ant. We looked at the effects of Monomorium venom toxicity, venom utilization, and aggressive physical interactions on Monomorium and Argentine ant survival rates during arena trials. The venom toxicity of the two species co-occurring with the invasive Argentine ants was found to be significantly higher than the toxicity of the two species which do not. There was no correlation between venom toxicity and Monomorium survival; however, three of the four Monomorium species displayed ... : Arena fight and venom usageThe table "Arena fight and venom usage.csv" corresponds to the manuscript sections of the same name. It contains the mortality of Argentine ant and workers of four Monomorium ant species after 1, 4 and 24 hours, as well as behavioural responses and observed venom usage of ant workers in the arena trials. It furthermore contains data derived from this raw data (for example relative occurence of behaviours). The experimental design is explained in the publication in the methods section with the same name as the datafile, further description of this and the other datafiles associated with this publication can be found in the ReadMe.txtArena fight and venom usage Argentine ant SurvivalThe table "Arena fight and venom usage Argentine ant Survival.csv" corresponds to the manuscript section "Arena fight and venom usage". It contains data represented in the Argentine ant Mortality column in table "Arena fight and venom usage.csv" formatted for a survival analysis. The experimental design ...
