Definitions &Translations A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index. The area that is used to define a sexual population is defined as the area where inter-breeding is potentially possible between any pair within the area.

Definitions &Translations The probability of interbreeding is greater than the probability of cross-breeding with individuals from other areas. Under normal conditions, breeding is substantially more common within the area than across the border. In sociology, population refers to a collection of humans.

How Many People Have Ever Lived on Earth? Population growth. In biology, population growth is the increase in the number of individuals in a population. Global human population growth amounts to around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012. It is expected to keep growing, and estimates have put the total population at 8.4 billion by mid-2030, and 9.6 billion by mid-2050.

Population genetics Population genetics. Population genetics is a subfield of genetics that deals with genetic differences within and between populations, and is a part of evolutionary biology. Studies in this branch of biology examine such phenomena as adaptation, speciation, and population structure.

Population Key. A population is a summation of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding. In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index.he population of some countries, such as Nigeria, is not even known to the nearest million, so there is a considerable margin of error in such estimates. Researcher Carl Haub calculated that a total of over 100 US billion/100 000 million people have probably been born in the last 2000 years.

What is population? Other countries have a more pyramidal shape with a wide base, reflecting higher infant mortality and greater risk of early death. [edit] Population growth Main article: Population growth Population growth is change in population over time. It also can be quantified as the change in the number of individuals in a population per unit time.

What Is Ecology? - Definition & Explanation Population Ecology. A population is a group of individuals belonging to the same species and living in the same geographic area at a given time. They use the same natural resources and are affected by similar environmental factors. Population ecology examines the factors affecting population density and distribution. Population density is the number of individuals in a given area or volume. Population distribution is how spread out the individuals are in that area. Basically it is how populations change over time.
