CBD Seminar: Menopause and intra-genomic conflict
Dr Francisco Ubeda
Royal Holloway

Menopause is the transition from reproductive to non-reproductive life well before natural death. Rather than involving a smooth, rapid change, it is normally preceded by a long period of erratic hormonal fluctuations that are accompanied by a plethora of unpleasant symptoms. Here we suggest that this turbulent period owes to a conflict of interest, between a woman’s maternally-inherited and paternally-inherited genes, over the trade-off between personal reproduction and cooperative care of neighbours’ young. We formulate a mathematical model of kin selection in a demographically structured population showing that there is conflict over fertility between genes with different parental origin. We formulate two mathematical models of game theory showing that this conflict is resolved through two alternative gene expression strategies: expression of one copy and silencing of the other (classic genomic imprinting), and random expression of one copy and constant expression of the other (novel form of genomic imprinting). These two forms of conflict resolution help explaining the unpleasant symptoms of menopause. We investigate which of these symptoms are expected to be caused by the maternally-inherited versus the paternally-inherited genes. We show that demographic differences between ancestral human populations may explain the variability in age of onset of menopause, and the variability of symptoms observed among different ethnic groups during the period of time preceding menopause. Our model informs the assessment of a woman’s risk of developing osteoporosis and cardiovascular disease, suggests epigenetic therapies for preventing breast and ovarian cancers, and provides guidance on family planning based upon a woman’s ancestral background.

SOI seminar: Genetic diversity in salmonid populations: The role of life history diversity and habitat fragmentation
Prof Daniel Ruzzante
Dalhousie University

click for details

Atlantic salmon exhibit an anadromous life history where individuals migrate out to sea where they spend a year or longer before returning to their natal grounds to reproduce. Some individuals, however, mature as parr without going out to sea. In this presentation I will describe evidence of the role played by parr maturation in the maintenance of genetic diversity in Atlantic salmon. I will also describe our efforts to understand how habitat fragmentation and the spatial configuration of populations affect the distribution of genetic diversity in fragmented freshwater systems.
