What is a population in ecological terms?

In ecological terms, a population is defined as the members of a species living in the same place at the same time. This definition underscores the importance of both spatial and temporal factors in understanding population dynamics. A population encompasses all individuals of a specific species within a defined geographical area, allowing ecologists to study various interactions, breeding behaviors, resource competition, and survival rates specific to that group. The concept of populations is fundamental for examining how species interact with each other and their environment, assessing factors like population density and distribution, which can significantly impact ecosystems and biodiversity.

Understanding this definition is crucial for further ecological studies, such as examining how populations respond to environmental changes, human impacts, and conservation efforts targeting specific species. It is distinct from other concepts like community (which refers to multiple species living together) and habitat (which focuses on the area occupied by a species).
