What is the significance of rare species?

Rare species are often the best indicators of the state of the community. This is due to the fact that in order to maintain the life of rare species, strictly defined combinations of various factors are required (for example, temperature, humidity, soil composition, certain types of food resources, etc.). Maintaining the necessary conditions largely depends on the normal functioning of ecosystems, so the extinction of rare species allows us to conclude that the functioning of ecosystems has been disrupted.
In communities with high diversity, many species occupy a similar position, inhabiting the same area of ​​space. In such a community, a change in living conditions under the influence of, for example, climate change or other factors can lead to the disappearance of one species, however, this loss will be compensated for by other species that are close to the one that was eliminated in its specialization.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
