The consequences of forced migrations are felt globally and are faced by millions of people each year. A critical question is how these refugees adjust to their new environments and eventually integrate into the host population. A number of factors can influence the ultimate assimilation of migrant populations and these are frequently related to the characteristics of the migrants (for example, demographic variables and socio-economic background), flight (for example, cause of flight), host country or region (for example, natural resources) and the resettlement policies of host populations. One way to measure the successful settlement and assimilation of displaced populations is to look at the number of times an individual relocates after their initial arrival in a host country and to analyse which factors affect these moves. In general, the more individuals move, the less likely they are to integrate.

Simon's latest work on the demography of grandmothers is now out in PLoS ONE. 

We were delighted to host Professors Martin Daly and Gretchen Perry for a day of excellent talks, with a particular focus on grandmothering and alloparental behaviour.

The manuscript "The transition to modernity and chronic disease: mismatch and natural selection" by Stephen Corbett, Alexandre Courtiol, Virpi Lummaa, Jacob Moorad and Stephen Stea

Two papers out now from Simon's PhD project!

1) Changes in the Length of Grandparenthood in Finland 1790-1959, published in the Finnish Yearbook of Population Reasarch. In this paper, the team investigated how the shared time between grandparents and grandchildren changed across the demographic transition and with industrialisation. This shared time was low and stable before these major events, and began to increase rapidly after they began.

2) Limited support for the X-linked grandmother hypothesis in pre-industrial Finland, published in Biology Letters. Here, we tested whether slight differences in relatedness via the X-chromosome might lead to differences the survival of male and female grandchildren with maternal or paternal grandmothers. Though two of three predictions were supported, we concluded that the X-linked grandmother hypothesis cannot account for lineage differences by itself. 

Our latest paper shows that early-life environment is associated with sex differences in adult mortality and expected lifespan. Out now in Ecology Letters:
