Research topics

  • Population structure and habitat use of large blue butterflies
  • This topic constituted the main part of my PhD. I was particularly interested if Maculinea populations can fit into any distinct category regarding their population spatial structure. I analyzed mark-recapture datasets of local populations to characterize the microdistribution and within-habitat movement of butterflies. We have recently analyzed 9 mark-recapture datasets of M. arion from all over Europe (see publications). Currently I'm working on a comprehensive analysis of several mark-recapture datasets on Maculinea butterflies from Hungary. I aim to identify the most influential environmental factors that affect the demography of these endangered species. Moreover, we conducted a management experiment on wet meadows to study the effects of mowing on populations of the scarce large blue (Maculinea teleius), its host plant and host ants, and plant diversity (Kőrösi et al. 2014; Szépligeti et al. in press).
  • Pollination and other ecosystem services
  • I am involved in a project that aimed to reveal the effects of landscape heterogeneity and climate-induced phenological mismatches on pollination and biological control in apple orchards (see Földesi et al. 2016 & several ms in the pipeline).
  • Resource ecology of butterflies
  • We collect detailed observations on the flower-visiting behaviour of clouded Apollo butterflies (Parnassius mnemosyne) and test field methods for estimating floral resource availability (Szigeti et al. 2016; Szigeti et al. in press). We are particularly interested in individual specialization and temporal change in resource-use (work in progress).
  • Sexual conflict in the clouded Apollo butterfly
  • The clouded Apollo butterfly (Parnassius mnemosyne) has a special mating behaviour as males create a 'sphragis' on females' genitalia after mating to prevent them from further matings. Our work involves the testing of several hypotheses on costs and benefits of sphragis-making for both males and females by field observations and experiments.
  • Movement pattern analysis of butterflies
  • By analysing movement trajectories of individual butterflies we showed that female Maculinea alcon butterflies have unexpectedly small home ranges (Kőrösi et al. 2008). As a guest at the University of Würzburg, I have been recently involved in preliminary experiments that aimed to develop new methods for the observation and analysis of butterfly movement under semi-natural conditions.
  • Community structure of butterflies
  • I am also involved in studies that aim to reveal how elevation and other environmental variables affect the species richness and composition of butterfly assemblages in the Western Himalaya and in the Nimba Mts. in Liberia (W Africa).
