Sex chromosome turnover in hybridizing stickleback lineages

X. Yi, D. Wang, K. Reid, X. Feng, A. Löytynoja, J. Merilä

The paper identifies an ongoing sex chromosome turnover in hybridizing stickleback lineages, where younger homomorphic sex chromosomes replace older heteromorphic ones in admixed populations.

Divergent evolution of head morphology between marine and freshwater sticklebacks

A. Fraimout, Y. Chen, K. Reid, J. Merilä

The paper shows genetically based adaptive differentiation in head size and shape between freshwater and marine sticklebacks, driven by limnetic feeding selection, but gill-raker traits show less conclusive genetic divergence.

Low heritability of crossover rate in wild sticklebacks

M. Kivikoski, A. Fraimout, P. Rastas, A. Löytynoja, J. Merilä

This study examines crossover rate variation in wild sticklebacks, finding low heritability and additive genetic variance, suggesting limited evolvability.

Inbreeding depression in an outbred nine-spined stickleback (Pungitius pungitius) population

A. Fraimout, P. Rastas, L. Lv, J. Merilä

The paper documents inbreeding depression in an outbred nine-spined stickleback population, showing a significant decrease in offspring survival with increasing parental IBD sharing and an average inbreeding load of 15.896.

Relaxed risk of predation drives parallel evolution of stickleback behaviour

A. Fraimout, E. Päiviö, J. Merilä

This study shows that reduced predation pressure in freshwater ponds drives parallel evolution of complex behaviors in sticklebacks by aligning evolutionary divergence with phenotypic plasticity responses.

Biases in demographic modelling affect our understanding of recent divergence

P. Momigliano, A.-B. Florin, J. Merilä

This study shows that ignoring population size changes in demographic models leads to biased divergence time estimates and incorrect model selection in species divergence analysis.

Oceans apart: Heterogeneous patterns of parallel evolution in sticklebacks

B. Fang, P. Kemppainen, P. Momigliano, X. Feng, J. Merilä

This study identifies geographic differences in parallel evolution patterns in sticklebacks, showing that most parallel evolution is unique to the Eastern Pacific.
