Population ecology from "summary" of Biology by Neil A. Campbell
Population ecology is the study of populations in relation to their environment, including environmental influences on population density and distribution, age structure, and variations in population size. Understanding how populations grow and interact with their environment is essential for making informed decisions about resource management and conservation. Populations are groups of individuals of the same species living in the same area at the same time. Population size is determined by factors such as birth rates, death rates, immigration, and emigration. These factors influence population growth and can lead to changes in population size over time. Population density refers to the number of individuals per unit area or volume. Different species have different population densities based on their habitat requirements and reproductive strategies. Population distribution refers to the spatial arrangement of individuals within a population. Clumped, uniform, and random...
