Offspring telomere length in the long lived Alpine swift is negatively related to the age of their biological father and foster mother.
A growing body of studies is showing that offspring telomere length (TL) can be influenced by the age of their parents. Such a relationship might be explained by variation in TL at conception (gamete effect) and/or by alteration of early growth conditions in species providing parental care. In a long-lived bird with bi-parental care, the Alpine swift (Apus melba), we exchanged an uneven number ...
متن کاملLife history and fitness consequences of ectoparasites
1. For iteroparous organisms life-history theory predicts a trade-off between current and future reproduction, and therefore the evolution of host responses to current parasite infestation that will maximize lifetime reproductive success. The parasite-induced variation in reproductive success is thus not the net result of parasite infestation alone, but the parasite-mediated outcome of optimal ...
متن کاملBreeding Experience Might Be a Major Determinant of Breeding Probability in Long-Lived Species: The Case of the Greater Flamingo
The probability of breeding is known to increase with age early in life in many long-lived species. This increase may be due to experience accumulated through past breeding attempts. Recent methodological advances allowing accounting for unobserved breeding episodes, we analyzed the encounter histories of 14716 greater flamingos over 25 years to get a detailed picture of the interactions of age...
متن کاملWithin-season increase in parental investment in a long-lived bird species: investment shifts to maximise successful reproduction? 2 Running title: within-season investment in long-lived bird 4
In nest-building species predation of nest contents is a main cause of reproductive failure and 16 parents have to trade off reproductive investment against antipredatory behaviours. While this trade-off is modified by lifespan (short-lived species prioritise current reproduction, long-lived 18 species prioritise future reproduction), it may vary within a breeding season, but this idea has only...
متن کاملGenetic Analysis of Response to Water Deficit Stress Based on Physiological Traits in Wheat
Dehydration is the most important limiting factor in agricultural production in arid and semi-arid regions, and water shortages (especially at the reproductive stages) due to lack of precipitation and unequal distribution are inappropriate for limiting the yield. In this research, cross between the Gasspard cultivar (dehydrated susceptible parent) and DN11 line (resistant parent) was performed....
