Consequences of sexual selection in mammals
FY 2011-12
Summary
Sexual selection is an evolutionary process that is the result of competition among members of the same sex for mates, or the result of mate choice behaviour made by one or both of the sexes. Sexual selection can influence behavioural, morphological, and physiological traits before and after copulation. My research program seeks to understand the consequences of sexual selection for mammals in the context of ejaculate investment, the immune system and the interaction between these two components. We use several mammal species (red squirrels, northern flying squirrels, eastern chipmunks, deer mice) and cutting edge techniques (e.g. genetic analyses and hematology) to answer questions such as: do males with larger testes that produce more sperm sire more offspring? What is the effect of sperm traits on fertilization success? Do males with active immune systems ""trade-off"" energy from reproduction? The results from our research program will be used to develop the theoretical and empirical framework of evolutionary ecology.
