Continent‐Wide Drivers of Spatial Synchrony in Breeding Demographic Structure Across Wild Great Tit Populations Open
Variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning 4° W–33° E and 35°–6…

Contaminants of emerging concern in an endangered population of common eiders (Somateria mollissima) in the Baltic Sea Open
Contaminants of emerging concern (CECs) are ubiquitous in aquatic environments and pose a range of biological effects including endocrine disruption. Yet, knowledge of their occurrence in wildlife including seabirds remains scarce. We inve…

Pollution-related changes in nest microbiota: Implications for growth and fledging in three passerine birds Open
Non-ferrous smelters emit toxic metals into the environment, posing a threat to wildlife health. Despite the acknowledged role of microbes in host health, the impact of such emissions on host-associated microbiota, especially in wild birds…

Heavy metal pollution exposure affects egg coloration but not male provisioning effort in the pied flycatcher <i>Ficedula hypoleuca</i> Open
Heavy metal pollution is known to negatively affect numerous traits in birds, including foraging, metabolism, immunity, and reproductive success. In this study, our primary aim was to assess the impact of metal pollution exposure on the vi…

Continent-wide drivers of spatial synchrony in age structure across wild great tit populations Open
Spatio-temporal variation in age structure influences population dynamics, yet we have limited understanding of the spatial scale at which its fluctuations are synchronised between populations. Using 32 great tit populations, spanning 3200…

The great tit HapMap project: A continental‐scale analysis of genomic variation in a songbird Open
A major aim of evolutionary biology is to understand why patterns of genomic diversity vary within taxa and space. Large‐scale genomic studies of widespread species are useful for studying how environment and demography shape patterns of g…

Fecal calcium levels of bird nestlings as a potential indicator of species-specific metal sensitivity Open
Sensitivity of bird species to environmental metal pollution varies but there is currently no general framework to predict species-specific sensitivity. Such information would be valuable from a conservation point-of-view. Calcium (Ca) has…

Cavity-breeding birds create specific microhabitats for diverse arthropod communities in boreal forests Open
The nests of secondary cavity-nesters located in tree cavities may form specific microhabitats of conservation importance due to their limited accessibility and availability. Species-specific nesting materials in nests of different seconda…

The effect of climate change on avian offspring production: A global meta-analysis Open
Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populati…

Mobile samplers of particulate matter – Flying omnivorous insects in detection of industrial contamination Open
Flying insects are potential mobile samplers of airborne particulate matter (PM). However, current knowledge on their susceptibility to PM is limited to pollinators. Insects' capacity for particle surface accumulation depends on the lifest…

Temperature synchronizes temporal variation in laying dates across European hole‐nesting passerines Open
Identifying the environmental drivers of variation in fitness‐related traits is a central objective in ecology and evolutionary biology. Temporal fluctuations of these environmental drivers are often synchronized at large spatial scales. Y…

Maternally transferred thyroid hormones and life‐history variation in birds Open
In vertebrates, thyroid hormones (THs) play an important role in the regulation of growth, development, metabolism, photoperiodic responses and migration. Maternally transferred THs are important for normal early phase embryonic developmen…
