• Frequency and Density-Dependent Selection on Life-History Strategies - A Field Experiment 

  Mappes, Tapio; Koivula, Minna; Koskela, Esa; Oksanen, Tuula A.; Savolainen, Tiina; Sinervo, Barry (Public Library of Science, 2008)

  Negative frequency-dependence, which favors rare genotypes, promotes the maintenance of genetic variability and is of interest as a potential explanation for genetic differentiation. Density-dependent selection may also ...

• Frequency-dependent selection and environmental heterogeneity as selective mechanisms in wild populations 

  Poikonen, Tanja (University of Jyväskylä, 2010)

• Advantage of rare infanticide strategies in an invasion experiment of behavioural polymorphism 

  Mappes, Tapio; Aspi, Jouni; Koskela, Esa; Mills, Suzanne; Poikonen, Tanja (Nature Publishing Group, 2012)

  Killing conspecific infants (infanticide) is among the most puzzling phenomena in nature. Stable polymorphism in such behaviour could be maintained by negative frequency-dependent selection (benefit of rare types). However, ...

• Epigenetic mechanisms behind phenotypic changes in different population densities in bank voles (Myodes glareolus) 

  Sorri, Elina (2017)

  Metsämyyrän (Myodes glareolus) fenotyyppisten muutosten epigeneettiset mekanismit eri populaatiotiheyksissä. Epigeneettisilla mekanismeilla on perustava rooli normaalissa geeniekspression aktiivisuudessa ja ne voidaan ...

• Frequency-dependent flight activity in the colour polymorphic wood tiger moth 

  Rojas Zuluaga, Bibiana; Gordon, Swanne; Mappes, Johanna (Chinese Academy of Sciences, Institute of Zoology, 2015)

  Predators efficiently learn to avoid one type of warning signal rather than several, making colour polymorphisms unexpected. Aposematic wood tiger moth males Parasemia plantaginis have either white or yellow hindwing ...
