From genes to communities, understanding how diversity is maintained remains a
fundamental question in biology. One challenging to identify, yet potentially ubiquitous …

Lifetime reproductive success (LRS), the number of offspring produced over an organism's
lifetime, is a fundamental component of Darwinian fitness. For taxa such as salmonids with …

Chromosomal inversions are ubiquitous in genomes and often coordinate complex
phenotypes, such as the covariation of behavior and morphology in many birds, fishes …

How natural diversity is maintained is an evolutionary puzzle. Genetic variation can be
eroded by drift and directional selection but some polymorphisms persist for long time …

Holobionts are highly organized assemblages of eukaryotic hosts, cellular microbial
symbionts, and viruses, whose interactions and evolution involve complex biological …

Iteroparity occurs when organisms reproduce more than once, and is seen as a bet-hedging
reproductive strategy. Despite a wealth of research on iteroparous Atlantic salmon …

Evolution of iteroparity is shaped by the trade-off between current and future reproduction.
We studied variation in iteroparity among 205 050 individual Atlantic salmon caught in 179 …

Populations composed of individuals descended from multiple distinct genetic lineages
often feature significant differences in phenotypic frequencies. We considered hatchery …

Recent empirical studies offer conflicting findings regarding the relation between host fitness
and the composition of its microbiome, a conflict which we term 'the microbial β-diversity …

Life‐history variation is the raw material of adaptation, and understanding its genetic and
environmental underpinnings is key to designing effective conservation strategies. We used …
