Experimental evidence for maternal offloading of mercury pollution via reproduction Open
Of the many pollutants released into the environment by human activities, mercury is among the most toxic. Interestingly, studies typically find reproducing females to exhibit lower mercury concentrations than males, suggesting that matern…

Experimental evidence for reproduction to increase mitochondrial respiration, but decrease mitochondrial efficiency, in females of a short-lived bird Open
Reproduction is generally considered as one of the most energy-demanding processes, causing a trade-off with survival. Although this “cost of reproduction” plays a pivotal role in theory on ageing and life-history evolution, the physiologi…

Poor developmental conditions decrease adult body size and egg size, but not egg laying rate and survival throughout adulthood: A long‐term experiment in a precocial bird Open
The quality of the environment during individual development is generally considered to have long‐lasting effects on performance in adulthood, but this is mainly based on observational studies that cannot pinpoint the causal pathways behin…

Does inbreeding affect personality traits? An experimental study in a precocial bird Open
Inbreeding is known to have deleterious effects on offspring performance, but the extent to which such inbreeding depression acts on traits is widely variable. In particular, condition-dependent traits that are subject to directional selec…

Inbreeding accelerates reproductive senescence, but not survival senescence, in a precocial bird Open
Inbreeding depression is predicted to increase with age, because natural selection is less efficient at purging deleterious alleles that are only expressed later in life. However, empirical results are scarce, and equivocal between studies…

Repeatable negotiation rules? Only females show repeatable responses to partner removal in a brood-provisioning songbird Open
Theoretical models indicate that the evolution of biparental care depends on how parents behaviourally negotiate their level of care in response to those of their partner and whether sexes and individuals consistently vary in their respons…

Male aggressiveness during the female fertile phase in relation to extra-pair paternity, plumage ornaments and female traits Open
In many bird species, physical aggression between males become more frequent during the female’s fertile period, as female encounters with extra-pair males are more frequent and can entail paternity losses. Male aggressiveness during this …
