Determinants of genetic diversity in sticklebacks

M. Kivikoski, X. Feng, A. Loytynoja, P. Momigliano, J. Merila

The paper assesses genetic diversity in stickleback populations and finds demographic factors, not life history traits, primarily determine genetic diversity levels.

Allopatric origin of sympatric whitefish morphs with insights on the genetic basis of their reproductive isolation

B. Fang, P. Momigliano, K. Kahilainen, J. Merila

The paper examines the genetic basis of reproductive isolation in sympatric whitefish morphs, finding that ecological adaptations in spawning time evolved in allopatry and maintain partial isolation.

Age-dependent genetic architecture underlines similar heritability of body size in sticklebacks

A. Fraimout, Z. Li, M. Sillanpaa, J. Merila

The paper shows that body size heritability remains constant in sticklebacks across ontogeny, but different genetic loci contribute to this heritability at different developmental stages.

Dissecting the genetic architecture of quantitative traits using genome-wide identity-by-descent sharing

A. Fraimout, F. Guillaume, Z. Li, M. J. Sillanpaa, P. Rastas, J. Merila

This study estimates quantitative genetic parameters in sticklebacks using IBD sharing, finding that low relatedness variance impairs estimation but half-sib designs allow accurate heritability and additive variance assessment.

Population structure limits parallel evolution

B. Fang, P. Kemppainen, P. Momigliano, J. Merila

The paper tests how population structure affects parallel evolution in two stickleback species, finding that genetic drift and subdivision limit local adaptation and parallel evolution.

The rise of the three-spined stickleback: eco-evolutionary consequences of a mesopredator release

B. K. Eriksson, C. Yanos, S. Bourlat, S. Donadi, M. Fontaine, J. Hansen, E. Jakubaviciute, K. Kiragosyan, M. Maan, J. Merila, A. Austin, J. Olsson, K. Reiss, G. Sundblad, U. Bergstrom, J. Eklof

The paper examines how the increase in three-spined stickleback due to declining perch populations has led to evolutionary and ecological changes in food web dynamics.

Genetic population structure constrains local adaptation in sticklebacks

P. M. Kemppainen, Z. Li, P. Rastas, A. Loytynoja, B. Fang, B. Guo, T. Shikano, J. Yang, J. Merila

The paper identifies genetic factors underlying pelvic reduction in sticklebacks and shows how population structure limits local adaptation.
