When peaceful coexistence turns into concurrence

To find out how rising temperatures could affect species diversity, biologists from the German Centre for Integrative Biodiversity Research (iDiv) and the Leipzig University have developed a simple experiment: they covered the bottom of different Petri dishes with litter material, then put in two species of springtails, that is, arthropods only a few millimetres in size, and then added mites feeding on springtails. Subsequently, for some of the Petri dishes they increased the ambient temperature
