Description We live in a society where environmental problems dominate public debate. Ecology is one of the sciences required to find solutions to such problems; terms and ideas that came originally from ecology are used in public discussions, and in legislation. This subject will introduce students to ecology: what is studied, how it is studied, what are the strengths and limitations of ecology. Current ecological thinking will be covered, from the scale of individual organisms, through populations, and up to communities and ecosystems. Methods of study will be highlighted using evidence from molecular ecology through to field investigations.

Successful completion of 60 credit points
Knowledge of first-year university biology satisfactory completion of Biodiversity and Cell Biology or equivalent and the concepts of classification, evolution, taxonomy, cellular processes plant and animal structure and function.
On successful completion of this subject, students should be able to:
- Define ecology as an area of study and place it in its scientific and social context
- Explain how factors can be identified as limits to distribution
- Describe the ecological concepts of populations, communities and ecosystems, and how tools such as modelling and molecular biology can be used to study them
- Explain how ecology is used to solve real-world problems such as harvesting from wild populations or managing fire regimes
- Describe indigenous approaches to the natural world and how these link to modern ecology
- Conduct ecological investigations safely and ethically in the field and laboratory, using sampling methodology correctly to obtain valid ecological data
- Use spreadsheets and statistical tools in analytical programs to enter, analyse and graph data and to draw appropriate conclusions from data
- Communicate findings correctly in oral or in written form using an appropriate style, accessing the scientific literature to place the findings in context
1. Scope of ecology from individual organisms to communities and ecosystems
2. Origin of ecology as a science
3. Indigenous approaches to nature and links to modern ecology
4. Limitations of ecology in studying large, complex systems, with random inputs, and a low level of understanding of how they work
5. Limits to distribution of species - dispersal, habitat selection, abiotic and biotic factors
6. Investigations of limits of dispersal eg transplant experiments, physiological response studies
7. Population studies - definition, methodology, life tables as a tool, genetic and evolutionary approaches
8. Population growth - exponential and logistic growth, factors that cause fluctuations in population numbers eg density dependence, time lags, stochastic variation in vital parameters. Stochastic vs. Deterministic models of population growth
9. Biotic interactions in populations - competition, predation, herbivory, beneficial associations
10. Experimental tests of biotic interactions
11. Applied ecology - harvesting from wild populations, fire ecology, molecular ecology
12. Community ecology - definitions, models of how communities function and change eg succession, patch dynamics, equilibrium and non-equilibrium models
13. Ecosystem ecology - primary and secondary production, introduction to biogeochemical cycles.
