Learning Objectives. Population dynamics refers to how populations of a species change over time. A population is a group of individuals of the same species that occupy a specific area over a certain period of time. Population Dynamics. Population dynamics is the branch of life sciences that studies short-term and long-term changes in the size and age composition of populations, and the biological and environmental processes influencing those changes. Information and translations of population dynamics in the most comprehensive dictionary definitions resource on the web. Key Takeaways Key Points. There are a number of different ways, taking different factors into account, to measure fertility rate. The "dynamics" of bird populations, the ways in which their numbers grow and shrink as time goes by, are controlled by the same general factors that control the size of human populations.An avian or human population has two kinds of input -- birth (natality) and immigration. Population Dynamics. The term "population dynamics" refers to how the number of individuals in a population … Information on key trends, such as the youth bulge in some countries, ageing population in other, migration and urbanization should guide planning. And each population has the same two outputs -- death (mortality) and emigration. Examine the impact of fertility rates on society and the various ways fertility is computed and discussed. Unlock Content Over 83,000 lessons in all major subjects Each population has a unique physical distribution in time and space. The population of each species has a unique physical distribution which changes over time and space based on how successful the species has … Meaning of population dynamics. Definition of population dynamics in the Definitions.net dictionary. After reviewing this lesson, you should be able to define and explain the various terms related to population dynamics in ecology. The study of a species’ population dynamics usually seeks to answer questions such as: What explains average abundance of a population? A population describes a group of individuals of the same species occupying a specific area at a specific time. Population dynamics is a study of the variation in the population of a particular species at a location over a given period of time. What does population dynamics mean? A population is a group of individuals (all members of a single species) who live together in the same habitat and are likely to interbreed. Population Dynamics.
