In my project, I make use of evidence synthesis (systematic review & meta-analysis) to understand phenotypic variation within and between species. My project is part of the DFG funded Collaborative Research Centre SFB-TRR 212 (more information here).
In my project, I aim to understand the effect of density on mating traits using tropical crickets (Gryllodes sigillatus). Specifically, I am using experiments to (1) examine whether female mating preferences are affected by perceived population density; (2) study whether density has an effect on sperm transfer dynamics; and (3) examine the plasticity in mate guarding behaviour shown by males. Furthermore, I am conducting a systematic review and meta-analysis to determine whether males or females have evolved a predominant control over the outcome of shared mating traits. My project is funded by the DAAD Doctoral Programme.
My research focuses on eco-evolutionary dynamics and rapidly changing environments. My PhD work primarily investigates the effects of density on offspring and breeder fitness, and how these relationships shape overall population dynamics. Using longitudinal data from a common tern colony, I study (1) the effects of early-life environmental conditions on fitness outcomes, (2) density and frequency-dependent selection patterns, (3) the role of individual plastic responses to density on fitness, and (4) how selection patterns may have changed after major avian influenza outbreaks at the colony.
