Expanding gene-environment causality in evolutionary genetics. This project aims to investigate how environmental experiences shape phenotypes, engender variance in populations and ultimately contribute to evolution. It targets new discoveries for how environmental effects can multiply throughout ontogeny and/or propagate across generations. Although widely speculated to support new evolutionary paradigms, such knowledge lacks scrutiny according to the formal metric of quantitative genetics. Thi ....Expanding gene-environment causality in evolutionary genetics. This project aims to investigate how environmental experiences shape phenotypes, engender variance in populations and ultimately contribute to evolution. It targets new discoveries for how environmental effects can multiply throughout ontogeny and/or propagate across generations. Although widely speculated to support new evolutionary paradigms, such knowledge lacks scrutiny according to the formal metric of quantitative genetics. This project seeks to expose guppy pedigrees to unique manipulations and reconcile adaptive evolution across captive and wild populations. The outcome is expected to address knowledge gaps in the life and human sciences and potentially inform goals in primary production and conservation.Read moreRead less
Can consistent individual differences in metabolic rate explain animal personality? Implications for fish and aquaculture in a warming climate. This project will determine if consistent individual differences in metabolic rate affect behaviour, growth, and reproduction in fish. If so, then we need to prepare for the fact that a warming climate will lead to reductions in fish growth and reproduction, because rising temperature directly increases metabolism and therefore maintenance costs.
