Ants weigh more than birds and mammals combined.

Biologists from the Julius Maximilian University and the University of Würzburg counted how many ants

живет на Земле.According to scientists, the population size is about 20 quadrillion, that is, 20∙1015 individuals. This amounts to about 12 Mt of carbon. This exceeds the total biomass of wild birds and mammals and accounts for about 20% of human biomass

For their work, the researchers selected andbrought together more than 500 scientific studies on ant populations. It was known that ants were found almost everywhere except the extreme polar regions, but previously scientists did not know exactly how these insects were distributed. 

It turned out that the highest density of antsobserved in the tropics, with most of all in forested and arid regions. Much less often, ants can be found in areas subject to strong human influence.

Researchers note that the number andAnt dispersal plays an important role in the development of ecosystems. For example, from one hectare of land, ants move on average up to 13 tons of soil per year. This has a significant impact on nutrient cycling and plant seed dispersal.

In future studies, scientists hope to understand what environmental factors affect the spread of ants.
