Data from: Rearing a virulent common cuckoo is not extra costly for its only cavity-nesting host

Peter Samaš, Jarkko Rutila, Marcel Honza, Michal Kysučan & Tomáš Grim
Virulent brood parasites refrain from arduous parental care, often kill host progeny and inflict rearing costs upon their hosts. Quantifying the magnitude of such costs across the whole period of care (from incubation through to parasite fledgling independence) is essential for understanding the selection pressures on hosts to evolve antiparasitic defences. Despite the central importance of such costs for our understanding of co-evolutionary dynamics, they have not yet been comprehensively quantified in any host of...

Data from: Around the Mediterranean: an extreme example of loop migration in a long-distance migratory passerine

Petr Klvaňa, Jaroslav Cepák, Pavel Munclinger, Romana Michálková, Oldřich Tomášek & Tomas Albrecht
An important issue in migration research is how small-bodied passerines pass over vast geographical barriers; in European-African avian migration, these are represented by the Mediterranean Sea and the Sahara Desert. Eastern (passing Eastern Mediterranean), central (passing Apennine Peninsula) and western (via western Mediterranean) major migration flyways are distinguished for European migratory birds. The autumn and spring migration routes may differ (loop migration) and there could be a certain level of individual flexibility in how individuals...

Data from: Moderate heritability and low evolvability of sperm morphology in a species with high risk of sperm competition, the collared flycatcher Ficedula albicollis

Anais Edme, Petr Zobač, Peter Korsten, Tomáš Albrecht, Tim Schmoll & Miloš Krist
Spermatozoa represent the morphologically most diverse type of animal cells and show remarkable variation in size across and also within species. To understand the evolution of this diversity, it is important to reveal to what degree this variation is genetic or environmental in origin and whether this depends on species’ life‐histories. Here we applied quantitative genetic methods to a pedigreed multigenerational data set of the collared flycatcher Ficedula albicollis, a passerine bird with high levels...

Data from: Sperm is a sexual ornament in rose bitterling

Carl Smith, Rowena Spence & Martin Reichard
In many taxa, odour cues mediate mating decisions. A key question is what these odours comprise, where they are produced, and what they signal. Using rose bitterling, fish that spawn in the gills of freshwater mussels, we investigated the role of sperm cues on female oviposition decisions using individuals of known MHC genotype. Male bitterling frequently released sperm prior to female oviposition and females responded with an increased probability of oviposition and released a greater...

Data from: Influence of interspecific competitors on behavioral thermoregulation: developmental or acute plasticity?

Barbora Winterová & Lumír Gvoždík
Many ectotherms reduce their exposure to changing thermal conditions using behavioral thermoregulation. The effectiveness of behavioral thermoregulation in maintaining ectotherm body temperatures within the target range is influenced not only by environmental (operative) temperatures but also by the presence of other con- and heterospecific individuals. How species’ interactions affect behavioral thermoregulation is largely unknown. Theory predicts that species’ interactions could affect the plasticity of behavioral thermoregulation in two ways, i.e. by developmental plasticity of a...

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...
