We are delighted to once again host PhD candidate Silke van Daalen, who will stay with us for most of September. We also had a quick visit from her supervisor, Professor Hal Caswell from the University of Amsterdam, in the last week of August. Both are mathematical biologists, currently working on stochastic processes in population demography and individual variation in stochasticity. Silke will have the dubious honour of accompanying the Human Life History Group and Myanmar Timber Elephant Project teams to our yearly group meeting (once again on beautiful Seili).

Both Elephant and Human Projects present, Lummaa Group had a great time discussing both current accomplishments and future prospects in Seili.

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:
