Population Flashcards
Population
Sum of individuals of species in an area
Population density
Number of individuals per unit area of species
Why are quadrets divided into smaller units
Greater accuracy
Demography
Statistical study of human population
Natality
Birth rate of a species
Mortality
Death rate
Quadret
Sample plot of specific size used for population studies
Percentage frequency
No of qudrets where species observed w.r.t all quadrets
High frequency indicated
High reproductive fitness
Level where natural selection of trait occur
Population
Unit of evolution
Population
Size of species indicates
It’s status in the habitat
Vegetation
Sum total of plant species
Factors affecting population
Mortality, Natality, immigration, emigration
