Demography of animal social species
This thesis focuses on the study of social animal populations, with the main objective of including aspects of sociality in demographic models. Animals are termed social when individuals associate with other individuals of the same species not exclusively for reproduction. Some aspects of sociality...

Animals are termed social when individuals associate with other individuals of the same species not exclusively for reproduction.
