Document Summary

Population of snowy owls it irrupted, due to an irruption of lemming (their food source in the arctic during the winter) A branch of the life sciences that studies the short term and long term changes in the size and age composition of population, and the biological and environmental processes influencing those changes. A population is a group of individuals of the same species that inhabit a defined area at a specific time. Usually higher than needed to replace the parents. Fecundity: potential number of offspring produced by an individual over time. A 3 year old fawn has a higher fecundity than a one year old fawn. Production: actual number of offspring produced in a given time. Changes throughout the life cycle of an organisms. Always expressed out of a 100, and males to females. Ex: 33:67 would mean 33 males to 67 females. Number of individuals of each age in a population. Reproductive capacity differs at each age class.
