Biography: 

Marina Fortes has a degree in Veterinary Medicine (2004) and a Master of Science (2007) in Animal Reproduction from the University of Sao Paulo, Brazil. She completed her PhD in 2012 at The University of Queensland (UQ). Her thesis title was “Genes and Genetic Markers Associated with puberty in beef cattle” and for that she had ongoing support from UQ and the Beef CRC (UQ Research Scholarship, UQ International Research tuition Award and Beef CRC top-up scholarship). After her PhD, Marina worked as a post-doc at the Queensland Alliance for Agriculture and Food Innovation and her main research project was titled “Transcriptome of the Pubertal Brahman Heifer”. On August 2014, Marina joined the School of Chemistry and Molecular Biosciences, to lecture in molecular genetics and bioinformatics and to establish a research group. Her group is interested in understanding how genetics influence reproductive biology in mammals.

Brief Research Description: 
Genetics and reproductive biology
Research Focus and Collaborations: 

The Livestock Genomics Group develops genomic technologies applied to improve genetic gain for complex phenotypes. Beef cattle fertility phenotypes, which are complex and therefore influenced by multiple genes are our main focus. Cattle fertility is a concern and an opportunity for improvement in Queensland's beef sector.

Imagine you have 100 cows, but they only produce 50-60 calves per year. An improved system would be to have 100 cows with higher genetic merit for fertility; which would produce 80 calves per year. Since the number of cows is the same (100) the environmental impact is similar, but more food is produced. In short, we like to think of more beef, less methane.

Current projects in the group use genome-wide technology (i.e. SNP chips and Next Generation Sequencing) to investigate the genetics of female and male cattle fertility. We study puberty, spermatogenesis and fertility indicators such as scrotal circumference or length of post-partum anoestrus. The aim is to further understand reproductive biology and to create tools for genetic improvement towards higher herd fertility, translated into improved weaning rates. 

 

Collaborative research expands the group activities and interests. Our group collaborates extensively with researchers at QAAFI and CSIRO Agriculture to further develop genomic selection approaches for beef cattle. Current collaborative research also includes genomic approaches to study chicken nutrition and growth. In another collaborative project, the genetics and proteomics associated with Human alcoholism are under investigation.
