DOI: 10.1007/s00035-018-0213-6
Abstract: Dioecious plants often exhibit deviations from expected 1:1 sex ratios. Genus Salix is a notable example of the female-biased sex ratio. Quite surprisingly, there are very few studies retesting observed bias patterns from the different… read more here.

DOI: 10.1038/s41586-019-0936-6
Abstract: Genomic instability can trigger cellular responses that include checkpoint activation, senescence and inflammation1,2. Although genomic instability has been extensively studied in cell culture and cancer paradigms, little is known about its effect during embryonic development,… read more here.

DOI: 10.1073/pnas.1719880115
Abstract: Significance Many modern European states trace their roots back to a period known as the Migration Period that spans from Late Antiquity to the early Middle Ages. We have conducted the first population-level analysis of… read more here.

DOI: 10.1093/beheco/arz030
Abstract: A biased adult sex ratio (ASR) can influence cooperative breeding behavior if the bias limits mating opportunities for the more abundant sex. We tested predictions associated with the ASR-cooperation hypothesis in the brown-headed nuthatch (Sitta… read more here.

DOI: 10.1093/biolre/ioac208
Abstract: Abstract Environmental stressors to which a fetus is exposed affect a range of physiological functions in postnatal offspring. We aimed to determine the in utero effect of steroid hormones on the reproductive potential of female… read more here.

The avian W chromosome is a refugium for endogenous retroviruses with likely effects on female-biased mutational load and genetic incompatibilities

DOI: 10.1098/rstb.2020.0186
Abstract: It is a broadly observed pattern that the non-recombining regions of sex-limited chromosomes (Y and W) accumulate more repeats than the rest of the genome, even in species like birds with a low genome-wide repeat… read more here.
