Differential temperature effects on photoperiodism in female voles: A possible explanation for declines in vole populations Open
Many mammalian species use photoperiod as a predictive cue to time seasonal reproduction. In addition, metabolic effects on the reproductive axis may also influence seasonal timing, especially in female small, short‐lived mammals. To get a…

Co-evolved maternal effects selectively eliminate offspring depending on resource availability Open
Many plants and animals adaptively downsize the number of already-produced propagules if resources become insufficient to raise all of them. In birds, mothers often induce hatching asynchrony by incubating first eggs before last eggs are l…

Prenatal Transfer of Gut Bacteria in Rock Pigeon Open
Vertebrates evolved in concert with bacteria and have developed essential mutualistic relationships. Gut bacteria are vital for the postnatal development of most organs and the immune and metabolic systems and may likewise play a role duri…

Replication Data for: Prenatal transfer of gut bacteria in rock pigeon Open
This dataset consists of 82 data files of which 78 are zipped fastq files containing the raw sequence data with two files per sample: R1 and R2. The names of the zip files start with the sampleID. Summary: Vertebrates evolved in concert wi…

Organizing effects of adverse early‐life condition on body mass, compensatory growth and reproduction: experimental studies in rock pigeons Open
Early‐life food conditions can have profound impact on adult behavioural performance. In song birds, early‐life food conditions affect adult physiology and cognitive performance such as song learning and spatial learning. However, effects …

Canalization of development reduces the utility of traits as fitness biomarkers: feather fault bars in nestling birds Open
Summary Biomarkers that predict fitness are instrumental in unravelling mechanisms that link environmental conditions to fitness. However, development is likely to be better canalized for traits with stronger fitness effects. As a conseque…

Maternal adjustment or constraint: differential effects of food availability on maternal deposition of macro‐nutrients, steroids and thyroid hormones in rock pigeon eggs Open
In oviparous species like birds, eggs provide the direct environment in which embryos are developing. Mothers may adjust different egg components in different ways in reaction to environmental cues either to adjust offspring development or…

Territory Quality and Plumage Morph Predict Offspring Sex Ratio Variation in a Raptor Open
Parents may adapt their offspring sex ratio in response to their own phenotype and environmental conditions. The most significant causes for adaptive sex-ratio variation might express themselves as different distributions of fitness compon…

Addendum to: ‘Reproductive effort accelerates actuarial senescence in wild birds: an experimental study’ Open
We recently showed that manipulation of reproductive effort over the entire lifespan modulated the rate of actuarial senescence in free-living jackdaws Corvus monedula (Boonekamp et al. 2014). We manipulated reproductive effort by giving b…
