Data from: Across a migratory divide: divergent migration directions and non-breeding grounds of Eurasian reed warblers revealed by geolocators and stable isotopes

Petr Procházka, Vojtěch Brlík, Elizabeth Yohannes, Bert Meister, Jürgen Auerswald, Mihaela Ilieva & Steffen Hahn
Migratory divides represent narrow zones of overlap between parapatric populations with distinct migration directions and, consequently, expected divergent non-breeding distributions. The composition of the mixed population at a migratory divide and the corresponding non-breeding ranges remain, however, unknown for many Palaearctic-African migrants. Here, we used light-level geolocation to track migration direction and non-breeding grounds of Eurasian reed warblers (Acrocephalus scirpaceus) from three breeding populations across the species’ migratory divide. Moreover, by using feathers grown at...

Data from: Low genetic diversity in small leading edge populations of a European paleoendemic Ramonda serbica (Gesneriaceae) in Bulgaria

Galya Petrova, Stefan Petrov & Michael Möller
Ramonda serbica Panč. (Gesneriaceae) is an endangered endemic species of the Balkan Peninsula. It has been the subject of several studies in the past, but has not yet been investigated in terms of its genetic variation. Here, an Inter Simple Sequence Repeat (ISSR) analysis was performed to determine the genetic diversity of five populations sampled from the geographically eastern fringe of its range in northwestern Bulgaria. We found low levels of genetic diversity and significant...

Data from: Low intensity blood parasite infections do not reduce the aerobic performance of migratory birds

Steffen Hahn, Silke Bauer, Dimitar Dimitrov, Tamara Emmenegger, Karina Ivanova, Pavel Zehtindjiev & William A. Buttemer
Blood parasites (Haemosporidia) are thought to impair the flight performance of infected animals, and therefore, infected birds are expected to differ from their non-infected counterparts in migratory capacity. Since haemosporidians invade host erythrocytes, it is commonly assumed that infected individuals will have compromised aerobic capacity, but this has not been examined in free-living birds. We tested if haemosporidian infections affect aerobic performance by examining metabolic rates and exercise endurance in migratory great reed warblers (Acrocephalus...
