Molecular taxonomic methods are fully presented, as are the results of many recent studies, both molecular and morphological.

Despite major international investment in biofuels, the invasive risks associated with these crops are still unknown. A cohesive state-of-the-art review of the invasive potential of bioenergy crops, this book covers the identified risks of invasion, distributions of key crops and policy and management issues. Including a section on developing predictive models, this book also assesses the potential societal impact of bioenergy crops and how to mitigate invasive risks.

Provides information in manageable chunks, which is reinforced by questions and activities that encourage students to consider the practical application of science to everyday life. This work is useful for Higher Tier GCSE students.
