Populationszám
Populationszám is a term used in demography and ecology to denote the total number of individuals in a defined population at a specific time. It is a fundamental descriptor of a population’s size and forms the basis for calculating density, growth rates, and trends. The definition of the population depends on geographic boundaries, species, and the study purpose.
In practice, populationszám is not always observed directly, especially for large, mobile, or cryptic species. Direct
Common estimation methods include capture-mark-recapture, where a subset of individuals is captured, marked, released, and later
Other approaches combine census data with models of population dynamics, using birth, death, immigration, and emigration
Accurate estimates of populationszám support conservation planning, wildlife management, and epidemiological analyses. They enable assessment of
