10. Populations 'meta-populations' Shifting due to climate change

12. Populations Sex-ratios can vary. Effective population size. Pollen and seed migrate differently. Environmental gradients.

14. Species The coin and currency of conservation. Speciation. Reproductive Isolation Mechanisms. Extinction.
