The population of the world exceeds the number of people by millions of people and that will be left, in the next month, 8,000 million people.
The researchers conducted the best analysis to date world population of antsinsects that have colonized almost the entire world, and the estimated total is 20,000 billionor estimate 2.5 million for each person.
The number should not surprise us considering how ubiquitous these strong and social insects are, and the fact that they have flourished since the age of the dinosaurs.
The oldest known fossils date back about 100 million years to the Cretaceous period. “Pants really play an important role in almost every field,” said the scientist Patrick Schultheis of the University of Würzburg in Germany, co-senior author of the study published this week in the journal Proceedings of the National Academy of Sciences.
“They are important for cycling, decomposition processes, plant seed dispersal and soil disturbance.. Ants are also a diverse group of insects, with many different types of work,” he explained.
“But most importantly, It is their wealth that makes them important players in society”Schultheiss said. There are more than 12,000 known species of ants, which are usually black, brown, or red in color and have three body parts.
There are 2.5 million ants per person
The size of one millimeter to 3 centimeters long, they usually live in the soil, leaf litter or decaying plants, and sometimes in people’s kitchen.
Ants, whose closest relatives are bees and wasps, are common everywhere in the world, as travelers know, except for Antarctica, Greenland, Iceland, and a few countries.
“I was surprised that the biomass of ants is higher than wild animals and birds together, reaching 20% of human biomass. That makes you think about the scale of their impact,” he said. . co-author Sabine Nooten, also from the University of Würzburg and the University of Hong Kong.
“I find the diversity of ants very interesting. They can be small or large and show unusual features,” Nooten added, referring to the widespread caterpillars called Strumigenys, known for a long time, mouth used to kill small invertebrates.
The researchers based their analysis on 489 studies of ant populations across all countries where these insects live.
Schultheiss said “Our data set represents a collection by thousands of scientists. We can present the number of ants for different regions of the world and estimate them global numbers and biomass,” said Schultheiss.
