What is organismal population ecology?

Organismal ecology focuses on the morphological, physiological, and behavioral adaptations that let an organism survive in a specific habitat. Population ecology studies the number of individuals in an area, as well as how and why their population size changes over time.

What is population mortality?

mortality, in demographic usage, the frequency of death in a population. The risk of death for both sexes is high immediately after birth, diminishing during childhood and reaching a minimum at 10 to 12 years of age.

What is population density in biology?

Population density is the number of individuals per unit geographic area, for example, number per square meter, per hectare, or per square kilometer. From: Insect Ecology (Fourth Edition), 2016.

What is population demography in biology?

Demography is the statistical study of population changes over time: birth rates, death rates, and life expectancies. Each of these measures, especially birth rates, may be affected by the population characteristics described above. These demographic characteristics are often displayed in the form of a life table.

What is demography of a population?

Demography is the statistical study of human populations. Demographers use census data, surveys, and statistical models to analyze the size, movement, and structure of populations.
