Amanda Pettersen

Postdoctoral fellow | PhD

I am a Wenner Gren postdoctoral fellow at Lund University. I am interested in understanding the causes and consequences of phenotypic variation, in particular for early life history and developmental traits. For my PhD work I measured metabolic scaling with size and temperature during development in marine invertebrates and fish to understand key patterns in life-history theory. I used a combination of field work, measures of physiological rates, and meta-analyses to propose potentially general mechanisms for variation in maternal investment strategies. I also measured selection on metabolic rate and key life-history traits to determine how micro-evolutionary processes can maintain variation in metabolic rates, and drive the pace-of-life across environments. In my current position at Lund University, I aim to investigate the contribution of maternal effects as a mechanism for rapid countergradient adaptation in wall lizards. To answer how populations adapt to cool climates, which severely limits embryo growth, I will study populations across the native range, as well as populations introduced from Italy to England. I will combine field sampling and experimental work to determine the biochemical and physiological mechanisms, and the underlying genomic basis, of maternal and embryonic adaptations to cool climate.
