In the article Evolution of springtails , I point out that springtails have managed to survive through geological eras, unlike other animal species that have suffered mass extinctions. These extinctions can be linked to biological changes in the environment such as episodes of plant proliferation...
Biotope of springtails
Have we ever wondered what our forests and grasslands would be like if the leaves that fall every autumn remain on the ground as they are? An important role of springtails is their contribution to the ecological balance of the soil microfauna, which allows the dissemination and regulation
It seemed to me useful to write an article to briefly discuss how soils evolve from the stage of the source rock. This process is the same since the origins of the Earth. Without him, life might not exist in the forms we know today. The sketch below1 summarizes the formation of soils in four
While some predatory insects hunt "on the run" or in flight, others adopt a motionless position and capture their prey from a distance with their front legs or their modified mouthparts. This is the case for mantises, mantis religiosa or certain bugs...
For a long time the study of the soils was reduced essentially to chemical analyzes, in order to detect the presence and the concentration of various chemical compounds. But the results obtained did not tell us anything about their interaction between these substances and the organisms
Above, we can see the diversity of biotopes in which springtails evolve. Each term included in this scheme characterizes a customary habitat for springtails. They are found living in the interstices of sands at the seaside, then on the surface, in the superficial layers of soils and finally in the soils themselves
Crossing the geological eras, some species of springtails current are similar to Oligocene fossils (-30 Ma) tending to show that they are rather "finished". With regard to the appearance of homo erectus (-1.8 Ma) or that of our own species, homo sapiens (-100 000 years) and given our way of
In the article Elements of taxonomy we note, within the animal kingdom, a phylum called Arthropods (from the Greek arthron (articulations) and podos (feet"). These invertebrates themselves have four sub-branches in which Crustaceans, Arachnids, Hexapods
