Lists of organisms by population
From Wikipedia, the free encyclopedia
This is a collection of lists of organisms by their population. While most of the numbers are estimates, they have been made by the experts in their fields. Species population is a science falling under the purview of population ecology and biogeography. Individuals are counted by census, as carried out for the piping plover;[3][4] using the transect method, as done for the mountain plover;[5] and beginning in 2012 by satellite, with the emperor penguin being first subject counted in this manner.[6]
