dr Maciej Dańko lecture


We invite you for the next Tuesday seminar, March 27, at 12:15 at the Biological and Chemical Research Centre, room 0.38, to the invited lecture by dr Maciej Dańko:

The role of extrinsic mortality in shaping life history traits including senescence

The Williams’ hypothesis is one of the most widely known ideas in life history evolution. It states that higher adult mortality should lead to faster and/or earlier senescence. However, some of the classic theories (Hamilton’s indicators of selection) do not support this prediction. Increased awareness of this fact has caused a crisis of misinformation among theorists and empirical ecologists. We resolve this crisis by outlining key issues in the measurement of fitness, assumptions of density dependence, and their effect on extrinsic mortality. The classic theory apply only to a narrow range of ecological contexts where density-dependence is absent or is present, but its effect is unrealistic. Deriving new methodology to incorporate density, by using a more appropriate measure of fitness, shows that broad ecological contexts exist where Williams’ hypothesis is supported.

Dr Maciej J. Dańko is a theoretical biologist, evolutionary demographer, and statistician at Max-Planck Institute for Demographic Research in Rostock in Germany:
