The films in this series provide explanations of the fundamental principles of population ecology.

"A particular objective of all three films is to present visual examples of concepts that are probably new or beyond the experience of most students, or alternatively, use familiar organisms to reveal a totally unfamiliar principle, activity or environment." Writer/Director, and award-winning environmental filmmaker, David Barrow.

EPISODES

Communities Reveals the structure and composition of a rainforest.  It displays a myriad of populations living in conjunction with one another as the "rainforest community" and examines the way the community functions, the factors that cause change and the way all life is tied to the community structure.

Ecosystems and Interactions Illustrates the importance of the sun as the prime energy source behind all ecosystems. The interaction of these ecosystems with one another and their environment is examined through the analysis of nutrient cycles and food chains. The web of life can be very delicate and the human influence particularly has the capacity to radically alter it. Unusual visual examples, including the mangrove-eel grass community, are used to show how plants and animals obtain energy and to illustrate the processes that support and nourish living organisms.

Populations Using a wide range of visual examples, Populations describes most of the principles that cause populations to look and behave as they do. Both plants and animals exist in populations. In this way they are organised for survival should any change threaten their community. Existing in a dynamic state of flux, populations are controlled and influenced by many factors, with no population capable of living in isolation. Population changes, and how plants and animal ensue their survival are themes within this film.
