Some connections and “Meeting points” of microbial ecology with zoological ecology: What can we learn?

Living things constitute different ecosystems. According to the definition, an ecosystem has to contain organisms that carry out the primary production of that particular ecosystem. On the foundation laid by the green plants and photo- or chemosynthesizing microbes, various biological networks are formed for circulating nutrients, metabolites, biological signals and molecular information. In this chapter, we briefly discuss some points of contact between microbes and their animal or human hosts within these networks. Studying the corresponding interactions can give leads to both microbial and zoological ecology disciplines, and to the corresponding scientific studies. The animals carry their individual microbiomes with them. Those microbiological communities reflect to the nutrition, influencing the animal health. However, the ecological principles work differently for the animal and microbial individuals.
