Põhiliike

Põhiliike is an Estonian term that translates to "main species" or "primary species." It refers to the dominant or most abundant organism within a specific ecological community or habitat. This species plays a crucial role in shaping the environment and influencing the populations of other organisms. The põhiliike is often determined by factors such as resource availability, predation pressure, or competitive advantage. Its presence can dictate the overall structure and function of the ecosystem. Identifying the põhiliike is essential for understanding ecological dynamics and for conservation efforts. For example, in a forest ecosystem, a particular tree species might be considered the põhiliike if it forms the majority of the canopy and provides the primary habitat for many animals. In a marine environment, a specific type of algae could be the põhiliike if it forms extensive beds that support a diverse community of invertebrates and fish. Changes in the population of the põhiliike can have cascading effects throughout the entire ecosystem, highlighting its significance.
