Fields of interest / focus of work 

 

In my research, I focus on the evaluation of population connectivity of European Turtle Doves (Streptopelia turtur), which is important information in the field of species protection. Turtle Doves experienced a strong population decline of more than 78% since 1980 and are Europe’s only long distance migrating columbids, crossing southern Europe, the Mediterranean and Sahara desert to reach their winter quarters in the sub-Saharan belt. Because Turtle Doves are a legal game species, I further analyse the impact of hunt on different European populations. Also, the interest in information about parasite infections was raised by finding a virulent genetic lineage of Trichomonas gallinae in Turtle Doves from the UK, a protozoan that can cause death due to starvation or suffocation. This is why I also work on the evaluation of parasite prevalence, occurrence of virulent lineages and potential effects on the population level.
