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 ...

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 ...
Oksanen, Tuula (University of Jyväskylä, 2002)Any organism has a limited amount of resources, which have to be partitioned among several activities such as maintenance, growth and reproduction. Reproductive effort is defined as the proportion of parental resources ...
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 ...
