Ecology: the biology of interaction. 1.09. Stability of biosystems

A characteristic feature of regulation by the principle of negative feedback is that it leads to oscillations of the regulated variable. If an impact drives the biosystem beyond the limits of its regulation by negative feedbacks, it will transition to a different state. Positive feedbacks will...

Ecology: The Biology of Interactions. 1.07. Regulation of Biosystems

A direct link is the effect of some factor on the system under study, its control (example: turning the wheel, the driver changes the car's direction of movement). Feedback is the dependence of the controlling effect on the state of the system itself (example: a change in the car's movement …

Ecology: the Biology of Interactions. 1.05. Levels of Organization of Biosystems

Biological systems are organized hierarchically, and at each level regulation is carried out using similar principles. The systems approach that gained development at the end of the twentieth century, going back in its development to Ludwig von Bertalanffy, is connected with the fact that systems composed of similarly interconnected...

Ecology: The Biology of Interactions. 1.01. What Is “Ecology”?

Before beginning the study of the course of general ecology, one should discuss the very meaning of the concept of “ecology.” Surprisingly enough, in Ukraine and, more broadly, in the post-Soviet space, there is no single opinion concerning the meaning of this term. To answer this question, one must turn …
