The repeated adaptation of oceanic threespine sticklebacks to fresh water has made it a
premier organism to study parallel evolution. These small fish have multiple distinct …

The Earth's polar regions are low rates of inter‐and intraspecific diversification. An extreme
mammalian example is the Arctic ringed seal (Pusa hispida hispida), which is assumed to …

Invasive species are one of the main threats to global biodiversity and, within marine
ecosystems, tunicates feature some prominent examples. Styela plicata is an ascidian …

Mutation rate is a fundamental parameter in population genetics. Apart from being an
important scaling parameter for demographic and phylogenetic inference, it allows one to …

How invasive species cope with novel selective pressures with limited genetic variation is a
fundamental question in molecular ecology. Several mechanisms have been proposed, but …

Host-associated microbiota can influence host phenotypic variation, fitness and potential to
adapt to local environmental conditions. In turn, both host evolutionary history and the …

Recent discoveries of sex chromosome diversity across the tree of life have challenged the
canonical model of conserved sex chromosome evolution and evoked new theories on …

Inbreeding depression refers to the reduced fitness of offspring produced by genetically‐
related individuals and is expected to be rare in large, outbred populations. When it occurs …

The nine-spined stickleback (Pungitius pungitius) has been increasingly used as a model
system in studies of local adaptation and sex chromosome evolution but its current reference …

Repeated phenotypic patterns among populations undergoing parallel evolution in similar
environments provide support for the deterministic role of natural selection. Epigenetic …
