Population Biology Journals

Theoretical Population Biology presents articles on theoretical aspects of population biology, specifically in the fields of demography, ecology, epidemiology, evolution, and genetics. Emphasis is placed on developing mathematical theories and models that enhance understanding of biological phenomena. The population changes with time. Natality (birth rate) and mortality (mortality rate) are two aspects that control the age structure of a population. Population biology is an interdisciplinary subject that integrates concepts from ecology, genetics, and evolution, with the aim of understanding how genetic variation arises and is maintained. A population refers to a group of organisms of a species that interbreed and live in the same place. So they are able to reproduce. A population is described as selected if the emphasis is on rapid reproduction to take advantage of good conditions. These species tend to produce a lot of offspring at a time, with little parental care, high mortality rate of young people (i.e. few individuals survive to reproduce), and generally short durations. They live in conditions that can be quite unpredictable due to environmental conditions. Examples of selected species include frogs, many insects and many rodents.
