“…Both partners participate in defending territory, incubation and feeding the young. We lack the data for the frequency of extrapair paternity from our population, but elsewhere it has been reported to occur among 8% of broods (Bukacińska et al ). Both females and males have on average two partners during the breeding life span (Brommer and Rattiste ).…”

According to handicap principle, exaggerated ornamental traits are supposed to exert costs on their bearers. However, there is much less theoretical and practical consensus about whether and under which conditions ornament expression should positively correlate with survival. We measured age‐related variation and survival selection on the size of white wing patches and black wing tips in a long‐lived monogamous seabird, the common gull Larus canus. Males had larger white patches than females but patch size showed concave relationship with age irrespective of sex, suggesting that white patch size was prone to senescence in both sexes. Extent of wing tip abrasion correlated negatively with the size of white patch, suggesting, in agreement with the Zahavian handicap hypothesis that only individuals with largest ornaments are able of maintaining them and not paying cost of displaying them. Areas of white wing patches and black wing tips correlated negatively. Irrespective of sex, survival selection favored birds with larger white wing patches and smaller black wing tips, which suggests that white and black wing markings may have coevolved as reverse components of a single ornament. Altogether, our results provide an evidence for the case where survival selection on ornamental traits in females is not weaker than in males. Absence of sex differences with respect to most of observed patterns is consistent with a prediction that among monogamous long‐lived species with biparental care, mutual mate choice leads to evolution of elaborate ornamental traits in both sexes.

“…Additive genetic (co)variances (V A and Cov A ) were calculated as twice the (co)variance component of original nest (V Origin and Cov Origin ) because full siblings share 50% of their genes (Lynch and Walsh 1998). Note that extra-pair paternity is very rare in gulls (Bukacinska et al 1998;Gilbert et al 1998). Environmental (co)variances (V E and Cov E ) were equal to the recipient nest component (V Recipient and Cov Recipent ), and phenotypic variances were calculated as the sum of the original nest, recipient nest and residual variance components (V P = V Origin ?…”

Quantitative genetic evidence for trade-off between growth and resistance to oxidative stress in a wild bird

et al. 2010

Why do animals not grow at their maximal rates? It has been recently proposed that fast growth leads to the accumulation of cellular damages due to oxidative stress, influencing subsequent performances and life span. Therefore, the trade-off between fast growth and oxidative stress may potentially function as an important constraint in the evolution of growth trajectories. We test this by examining a potential antagonistic pleiotropy between growth and blood resistance to controlled free radical attack in a wild bird using a cross-fostering design and robust quantitative genetic analyses. In the yellowlegged gull Larus michahellis, decreased resistance to oxidative stress at age 8 days was associated with faster growth in mass, across the first 8 days of life, suggesting a trade-off between mass growth and oxidative-stress-related somatic maintenance. We found a negative genetic correlation between chick growth and resistance to oxidative stress, supporting the presence of the genetic trade-off between the two traits. Therefore, investment of somatic resources in growth could be constrained by resistance to oxidative stress in phenotypic and genetic levels. Our results provide first evidence for a potential genetic trade-off between life-history and underlying physiological traits in a wild vertebrate. Future studies should explore genetic trade-offs between life-history traits and other oxidative-stress-related traits.

“…EPP has been shown to be low (3.6%) in a Polish population of common gulls (Bukaciń ska et al 1998), and such a rate is unlikely to seriously bias estimates of additive genetic (co)variance components (Charmantier & Réale 2005). Furthermore, EPP is particularly unlikely to bias additive genetic estimates for a female trait such as the laying date, because most information stems from the comparisons between mothers and daughters, whose relatedness is not affected by EPP.…”

Exploring plasticity in the wild: laying date–temperature reaction norms in the common gull Larus canus

2008

Exploration of causal components of plasticity is important for insight into evolutionary dynamics and an organism's ability to respond to climate change. Among individuals, variation in plasticity can be due to genotype-environment interaction (G!E) or a result from environmental effects associated with an individual. We investigated plasticity for laying date in the common gulls Larus canus, using data collected in Estonia during 37 years (nZ11 624 records on 2262 females, with 472 relatives). We used a sliding window approach to find the period in spring during which mean temperature best explained the annual mean laying date. Then, considering the spring temperature as a quantitative description of the environment, we used pedigree information and a random regression animal model to determine the variation in plasticity for the laying date-temperature relationship. We found that individuals differ in the plasticity of laying date (such that there is increased variation among individuals for the laying date in warmer springs), and that approximately 11% of variation in the laying date is heritable, but we found no statistical support for G!E. Plasticity in this species is not constrained by warmer springs.
