Population dynamics is the branch of biology that studies the size and age composition of population as dynamics system and the biological and environmental processes that drive them such as birth and death rates and immigration and emigration. The example scenarios are the aging of the population, the growth of the population or the decline of the population.
Population dynamic have the tradionally been the dominant branch of mathematical biology, which has a history of more than 210 yes although more recently the reach of mathematical biology has greatly expanded. The first principle of population dynamics is widely regarded as exponential law of Malthus, according to Malthus’s growth model.
