Early morning start 😴 but on my way to the joint ringers conference between Radolfzell and Helgoland to present some results about bird-tick interactions won through standardized monitoring of breeding birds ☺️

New Paper alert 📄

Rüppel et al. 2026 - "movetrack: An R package to model flight paths from radio-telemetry networks"
-> this makes it possible to transform station-based radiotelemetry data into actual flight path, validated with a plane flight.

New preprint! 🐥🦠🏝️

We study a great speciator, the silvereye, to test whether parasites follow island biogeography rules, and find that parasite diversity and isolation effects depend strongly on transmission strategy.

Led by PhD student Sarah Nichols.

I'm happy to share with you our new paper out now in Environmental Pollution!
Here, we experimentally studied the maternal offloading of mercury pollution via reproduction in an avian model species.

spring has sprung and the #dreamteam is out in the forest. first #geolocator robins have been spotted and data already secured - such exciting times. we use #lotek radiotelemetry and light and pressure loggers to understand partial #migration in a European #robin population in Northern Germany.

Analysis of ticks (Acari: Ixodida) and associated microorganisms collected on the North Sea Island of Heligoland - Parasitology Research Heligoland is an island located in the North Sea, where vegetation was almost destroyed as a result of heavy bombardment during and after the Second World War. However, over the past 70 years, the veg...

I am very excited to announce our new paper describing the tick communities on Helgoland. We highlighted a potentially stable population of a tick species which has not been described in Germany since the 1970s! Feel free to reach out if you have questions 😄

High-recombining genomic regions affect demography inference based on ancestral recombination graphs Abstract. Multiple methods of demography inference are based on the ancestral recombination graph. This powerful approach uses observed mutations to model

Happy to share our new paper OA in Genetics. We show that population genomic methods based on ARGs (ancestral recombination graphs i.e. genetic ancestry along chromosomes) for demography inference can be biased when applied to genomes with wide high-recombining regions. doi.org/10.1093/gene...
