Introduction
PhD Student at the Institute of Avian Research interested in behavioural and evolutionary ecology, with a focus on the physiological mechanisms underlying life-history variation within species. I'm investigating the effects of inbreeding on life-history traits and the causes and consequences of among- and within-individual variation in mitochondrial performance. I'm also conducting experimental research on the transfer of mercury pollution from parents to offspring in captive Japanese quail.

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 physiological mechanisms underlying it remain largely unresolved. As mitochondria synthesize 90% of the energy available...
Inbreeding can decrease male fertility, despite sperm cells being haploid. However, to date, the role of post-meiotic sperm senescence within the female in reducing fertilization probability of sperm from inbred males is unknown. In this study, we experimentally created inbred and outbred male Japanese quail (Coturnix japonica) and let them copulat...
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 behind such long‐term effects.
In this study, we performed a randomized controlled trial to test for causal effects...
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 selection are expected to show stronger inbreeding depression. However, while inbreeding effects on primary determin...
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.
Here we performed controlled matings between related and unrelated individuals of domesticated Japanese quail...
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 response (compensatory response). While the compensatory response has been widely investigated empirically, its repeat...
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 stage has been proposed as crucial for ensuring male reproductive success. Thus, plumage ornaments could repres...
