11. Maternal investment in male and female offspring in the fallow deer
Abstract : In this thesis, I investigate whether mothers of the polygynous fallow deer, Dama dama, bias their investment towards male offspring. I aim to answer the specific questions: (i) how is offspring fitness related to maternal investment?; (ii) do male fawns grow faster than female fawns during the period of maternal investment, and if so, why?; (iii) are male fawns more costly to raise than female fawns?; (iv) do fallow deer mothers adjust the sex of their offspring in relation to their ability to invest resources? To answer these questions I have collected and analysed data on reproduction of an enclosed fallow deer population and also performed an experimental study in which the level of investment was controlled for.
