This edition aims to fill an important gap in the Greek scientific literature.

It is a textbook that is internationally regarded as a "classic" introduction to population biology, as it achieves:

• covering all the fundamental concepts of this scientific domain,
• being educationally effective by smoothly connecting biological laws with their mathematical formulation, providing numerous hypothetical and real examples,
• and being epistemologically apt, prioritizing the precision and rigor of mathematical expression over lengthy descriptive approaches.

The book is intended for the Greek biologist - scientist and student - but also for anyone interested in the fields of ecology, taxonomy, demography, evolution, and biogeography.
