In the Nason lab I am interested in investigating the local- and landscape-level environmental factors that may affect interactions between the Sonoran Desert rock fig, Ficus petiolaris, and species-specific fig wasp mutualists (Pegoscapus pollinating seed consumer) and antagonists (diverse non-pollinating seed consumers), as well as fruit consuming lepidopteran larvae (Crambidae). I want to infer the past demographic history of the mutualists as well as their parasites, estimate the current effect of several ecological factors on the costs and benefits involved in the mutualism, and predict how global change might impact this interaction.
