Continental Patterns of Phenotypic Variation Along Replicated Urban Gradients: A Mega‐Analysis Open
Individual variation among and within natural populations can have eco‐evolutionary implications by, for example, affecting species interactions or evolutionary potential. Urban systems present a unique opportunity to evaluate how environm…

Positive covariation between current reproduction and subsequent performance in a raptor: Is the devil in the details? Open
The theory about reproductive trade‐offs suggests that as reproduction is costly, individuals should trade current reproduction against future reproduction or survival, leading to within‐individual negative covariation between current repr…

Telomere length varies with sex, hatching rank and year of birth in the Little Owl, Athene noctua Open
Telomeres are non-coding DNA sequences located at the end of linear chromosomes, protecting genome integrity. In numerous taxa, telomeres shorten with age and telomere length (TL) is positively correlated with longevity. Moreover, TL is al…

Cascading Effects of Conspecific Aggression on Oxidative Status and Telomere Length in Zebra Finches Open
Living in social groups may exacerbate interindividual competition for territory, food, and mates, leading to stress and possible health consequences. Unfavorable social contexts have been shown to elevate glucocorticoid levels (often used…

Does the Urban Environment Act as a Filter on the Individual Quality of Birds? Open
Phenotypic divergences of birds are common between urban and natural habitats and can result from different selective pressures between habitats or maladaptation to the city. No uniform patterns were observed, especially concerning markers…

Grandmaternal age at reproduction affects grandoffspring body condition, reproduction and survival in a wild population of lizards Open
Age at reproduction can influence the survival and future reproduction of an individual as well as that of their offspring. Remarkably, it has been shown that grandmaternal age at reproduction can also affect the characteristics of grandof…

Connecting the data landscape of long‐term ecological studies: The SPI‐Birds data hub Open
The integration and synthesis of the data in different areas of science is drastically slowed and hindered by a lack of standards and networking programmes. Long‐term studies of individually marked animals are not an exception. These studi…

Consequences of trace metal cocktail exposure in zebra finch (Taeniopygia guttata) and effect of calcium supplementation Open
Trace metal elements are significant stressors in urban areas. Their harmful effects on physiological parameters are demonstrated, but current laboratory studies are not representative of wild chronic exposure to a trace metal cocktail. Ca…

Nest-box temperature affects clutch size, incubation initiation, and nestling health in great tits Open
Lay Summary Seasonal organisms use temperature as a cue in reproductive decisions, but the role of climate change is not yet clear. Here, an experimental increase in temperature during laying in a small passerine bird reveals that heated f…

Reproductive costs in terrestrial male vertebrates: insights from bird studies Open
Reproduction requires resources that cannot be allocated to other functions resulting in direct reproductive costs (i.e. trade-offs between current reproduction and subsequent survival/reproduction). In wild vertebrates, direct reproductiv…
