The role of epigenetic modifications in bovid adaptation to environmental change. This project will explore the role of epigenetic change, where gene expression is regulated without changing the deoxyribonucleic acid (DNA) sequence, in how animals adapt to rapid climate change. This project will trace epigenetic markers in ancient bison and cows through 30,000 years of climate change, and identify key adaptive genes for the cattle industry.
Quantifying the effect of nutrient-gene interaction in utero in key tissues instrumental to productivity and sustainability of the beef industry. The cattle industry occupies 43 per cent of the land mass and provides 13 per cent of rural employment. Nutritional insult in utero affects postnatal reproductive and production traits in cattle and imposes epigenetic modifications. This project investigates the effect upon genes affecting appetite, ovarian development, adipogenesis, myogenesis and pos ....Quantifying the effect of nutrient-gene interaction in utero in key tissues instrumental to productivity and sustainability of the beef industry. The cattle industry occupies 43 per cent of the land mass and provides 13 per cent of rural employment. Nutritional insult in utero affects postnatal reproductive and production traits in cattle and imposes epigenetic modifications. This project investigates the effect upon genes affecting appetite, ovarian development, adipogenesis, myogenesis and post natal growth.Read moreRead less
Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selec ....Using phylogenomics to record the impacts of climate change, extinction and population fragmentation. This project will use ancient DNA from permafrost-preserved Steppe bison bones and bovid exome capture systems to build a detailed record of the genomic impacts of rapid climate and environmental change at the end of the Pleistocene (30 to 11 kyr). The project will analyse how ancestral genetic diversity is distributed amongst surviving bison populations, and the role of nuclear loci under selection and drift. It will create a novel temporal dataset of genomic adaptation and evolution, and will generate critical data for studies of evolutionary processes such as extinctions, speciation and conservation biology and management.Read moreRead less
