Aneta Arct, Auteur ; Szymon M. Drobniak, Auteur ; Samantha Mellinger, Auteur ; Rafał Martyka, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurDans Ibis (164(2) 2022)There is growing evidence that engaging in extra-pair copulations may be a strategy by which females can modify their initial mate choice if they are constrained by primary choice of the social mate. Several factors such as genetic similarity an[...]

Aneta Arct, Auteur ; Rafał Martyka, Auteur ; Szymon M. Drobniak, Auteur ; Wioleta Oleś, Auteur ; Anna Dubiec, Auteur ; Lars Gustafsson, AuteurAmbient temperature experienced by an animal during development or subsequently as an adult can affect many aspects of its behaviour and life-history traits. In birds, egg incubation is a vital component of reproduction and parental care. Severa[...]
Article
Joanna Sudyka, Auteur ; Aneta Arct, Auteur ; Szymon Drobniak, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurEvidence is accumulating that telomeres become shorter with advancing age and possibly explain some of the observed variation in longevity. Cross-sectional analyses have shown that species with shorter lifespans lose more telomeric repeats with [...]
Article
Edyta Podmokla, Auteur ; Anna Dubiec, Auteur ; Szymon M. Drobniak, Auteur ; Aneta Arct, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurHaemosporidians causing avian malaria are very common parasites among bird species. Their negative effects have been repeatedly reported in terms of deterioration in survival prospects or reproductive success. However, a positive association bet[...]
Article
Martins Briedis, Auteur ; Steffen Hahn, Auteur ; Lars Gustafsson, Auteur ; Ian Henshaw, Auteur ; Johan Träff, Auteur ; Miroslav Král, Auteur ; Peter Adamik, AuteurThe temporal and spatial organization of the annual cycle according to local conditions is of crucial importance for individuals' fitness. Moreover, which sites and when particular sites are used can have profound consequences especially for mig[...]
Article
Edyta Podmokla, Auteur ; Anna Dubiec, Auteur ; Szymon M. Drobniak, Auteur ; Aneta Arct, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurParasite species are usually specialists utilising specific host species, but parasite assemblages may differ substantially even between populations of the same species and show seasonal and annual fluctuations. Host characteristics such as indi[...]

Edyta Podmokla, Auteur ; Anna Dubiec, Auteur ; Szymon M. Drobniak, Auteur ; Joanna Sudyka, Auteur ; Adam Krupski, Auteur ; Aneta Arct, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurParasites are ubiquitous in the wild and by imposing fitness costs on their hosts they constitute an important selection factor. One of the most common parasites of wild birds are Plasmodium and Haemoproteus, protozoans inhabiting the blood, whi[...]

Natalia Pitala, Auteur ; Suvi Ruuskanen, Auteur ; Toni Laaksonen, Auteur ; Blandine Doligez, Auteur ; Barbara Tschirren, Auteur ; Lars Gustafsson, AuteurHormone-mediated maternal effects may be an important mechanism for adjusting offspring phenotype to particular requirements of the environment. We manipulated the levels of testosterone and androstenedione in the yolk of collared flycatcher Fic[...]
Article
Chris Wiley, Auteur ; Anna Qvarnstrom, Auteur ; Lars Gustafsson, AuteurBecause they are ubiquitous and typically reduce the fitness of hosts, parasites may play important roles in hybrid zone dynamics. Despite much work on herbivores and hybrid plants, the effect of parasites on the fitness of animal hybrids is poo[...]
Article
Blandine Doligez, Auteur ; Gregory Daniel, Auteur ; Patrick Warin, Auteur ; Tomas Part, Auteur ; Lars Gustafsson, Auteur ; Denis Reale, AuteurUnderstanding the evolution of a trait requires analysing its genetic basis. Many studies have therefore estimated heritability values of different traits in wild populations using quantitative genetic approaches on capture-recapture data of ind[...]
Article
Edyta Podmokla, Auteur ; Anna Dubiec, Auteur ; Aneta Arct, Auteur ; Szymon M. Drobniak, Auteur ; Lars Gustafsson, Auteur ; Mariusz Cichoń, AuteurExtra-pair matings comprise a common reproductive strategy among socially monogamous bird species. However, it remains unclear why females decide to mate with extra-pair males. Indirect benefits in terms of improving offspring genetic quality ar[...]
