Organisms' life history strategiies reflect the trade-off of finite resources to competing functions such as maintenance, growth and reproduction. It follows therefore, that allocation of resources to a reproductive event (for example) will come at a cost to growth, maintenance and possible future reproductive events. This module will explore relationships between: age and size, survival and reproductive performance. It will investigate the interaction between phenotypic variation resulting in selection coupled with the expression of genetic variation that facilitates a response to selection.

Assessment
All assessments are formative and summative, they contribute to the module grade. The module is 100% continuous assessment with no terminal examination. Practical assignments, group discussions and class presentations will be used to assess the learning outcomes on an ongoing basis.
