Data from: Across a migratory divide: divergent migration directions and non-breeding grounds of Eurasian reed warblers revealed by geolocators and stable isotopesPetr 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: Species richness effects on grassland recovery from drought depend on community productivity in a multisite experimentJuergen Kreyling, Jürgen Dengler, Julia Walter, Nikolay Velev, Emin Ugurlu, Desislava Sopotlieva, Johannes Ransijn, Catherine Picon-Cochard, Ivan Nijs, Pauline Hernandez, Behlül Güler, Philipp Von Gillhaussen, Hans J.

Biodiversity can buffer ecosystem functioning against extreme climatic events, but few experiments have explicitly tested this. Here, we present the first multisite biodiversity × drought manipulation experiment to examine drought resistance and recovery at five temperate and Mediterranean grassland sites. Aboveground biomass production declined by 30% due to experimental drought (standardised local extremity by rainfall exclusion for 72–98 consecutive days). Species richness did not affect resistance but promoted recovery. Recovery was only positively affected by...
Data from: Multilocus phylogeography of the European ground squirrel: cryptic interglacial refugia of continental climate in EuropeŠtěpánka Říčanová, Yordan Koshev, Oldřich Říčan, Nada Ćosić, Duško Ćirović, František Sedláček & Josef Bryja
The theory of classical and cryptic Pleistocene refugia is based mainly on historical changes in temperature, and the refugia are usually defined within a latitudinal gradient. However, the gradient of oceanic–continental climate (i.e. longitudinal) was also significantly variable during glacial cycles with important biotic consequences. Range-wide phylogeography of the European ground squirrel (EGS) was used to interpret the evolutionary and palaeogeographical history of the species in Europe and to shed light on its glacial–interglacial dynamic....
Local versus broad scale environmental drivers of continental beta diversity patterns in subterranean spider communities across EuropeStefano Mammola, Pedro Cardoso, Dorottya Angyal, Gergely Balázs, Theo Blick, Hervé Brustel, Julian Carter, Srećko Ćurčić, Samuel Danflous, László Dányi, Sylvain Déjean, Christo Deltshev, Mert Elverici, Jon Fernandez Perez, Fulvio Gasparo, Marjan Komnenov, Christian Komposch, Ľubomír Kováč, Kadir Kuntz, Andrej Mock, Oana Moldovan, Maria Naumova, Martina Pavlek, Carlos Prieto, Carles Ribera … & Marco Isaia
Macroecologists seek to identify drivers of community turnover (β-diversity) through broad spatial scales. Yet, the influence of local habitat features in driving broad-scale β-diversity patterns remains largely untested, due to the objective challenges of associating local-scale variables to continental-framed datasets. We examined the relative contribution of local- versus broad-scale drivers of continental β-diversity patterns, using a uniquely suited dataset of cave-dwelling spider communities across Europe (35–70° latitude). Generalized dissimilarity modeling showed that geographical distance, mean...
Data from: Co-infections and environmental conditions drive the distributions of blood parasites in wild birdsNicholas J. Clark, Konstans Wells, Dimitar Dimitrov & Sonya M. Clegg
Experimental work increasingly suggests that non-random pathogen associations can affect the spread or severity of disease. Yet due to difficulties distinguishing and interpreting co-infections, evidence for the presence and directionality of pathogen co-occurrences in wildlife is rudimentary. We provide empirical evidence for pathogen co-occurrences by analysing infection matrices for avian malaria (Haemoproteus and Plasmodium spp.) and parasitic filarial nematodes (microfilariae) in wild birds (New Caledonian Zosterops spp.). Using visual and genus-specific molecular parasite screening, we...
Data from: Low genetic diversity in small leading edge populations of a European paleoendemic Ramonda serbica (Gesneriaceae) in BulgariaGalya 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 birdsSteffen 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...
