• The maintenance of sexually antagonistic variation in reproductive success by negative frequency-dependence in the bank vole (Myodes glareolus) 

  Martiskainen, Henna (2011)

  Natural selection theory predicts low variance in traits closely related to reproductive success, since the most fit trait value should replace all the others. However, a considerable amount of variation is found in ...

• Density-dependent effects of sexual selection on sexual behaviour and female choice in two distinct wood tiger moth populations 

  Kartano, Liisa (2023)

  Seksuaalivalinta on lajin sisäisen lisääntymiskilpailun muoto. Sen kaksi ensisijaista ilmenemismuotoa ovat kilpailu parittelukumppaneista ja kumppaninvalinta. Vaihtelu populaatiotiheydessä voi vaikuttaa yksilöiden ...

• Reproductive success, local adaptation and genetic diversity in small plant populations 

  Lammi, Antti (University of Jyväskylä, 1999)

• Geographic mosaic of selection by avian predators on hindwing warning colour in a polymorphic aposematic moth 

  Rönkä, Katja; Valkonen, Janne K.; Nokelainen, Ossi; Rojas, Bibiana; Gordon, Swanne; Burdfield‐Steel, Emily; Mappes, Johanna (Wiley-Blackwell, 2020)

  Warning signals are predicted to develop signal monomorphism via positive frequency‐dependent selection (+FDS) albeit many aposematic systems exhibit signal polymorphism. To understand this mismatch, we conducted a large‐scale ...

• Selection on two behavioral genes : fitness effects of receptor genes for arginine vasopressin 1a and oxytocin in the bank vole Myodes glareolus 

  Lönn, Eija (University of Jyväskylä, 2017)

  Most variation in behavior is regulated by genes; nevertheless the mechanisms behind maintenance of genetic diversity at behavioral loci have remained mainly elusive in natural populations. I studied in my thesis ...
