Skin pigment differences of tiger snake populations and in response to UV exposure
This morphological honours project explores quantifying skin pigment differences between tiger snake populations - striped vs completely black - and in response to UV exposure over a season.
Researcher Vicki Thomson's research focuses on the evolution and adaptation of tiger snakes, with special emphasis on how island populations have diverged from the mainland over both long and short timeframes.
Current research includes:
- population genomic approaches to understanding the spatial genetic diversity of tiger snakes;
- evolution of venom to different suites of prey species;
- development of gigantism and dwarfism in body size on islands;
- head size and shape differences at the population level;
- evolution and adaptation of skin pigment between populations and in response to UV light exposure; and
- epigenetic regulation of phenotypic plasticity.
