This seminar links to NCEA Level 3 Achievement Standards:
- AS 90715 Describe the role of DNA in relation to gene expression
- AS 90716 Describe animal behaviour and plant responses in relation to environmental factors
- AS 90718 Describe applications of biotechnological techniques
About the presenters
Dr Guy Warman leads the Chronobiology Research Group at The University of Auckland. A range of chronobiology research is conducted at the university with interdisciplinary projects between the Faculty of Medical and Health Sciences and the School of Biological Sciences. Projects include molecular and behavioural chronobiology in both animals and plants, and applied research on human chronobiology and chronopharmacology.
