Thus, the early life environment can have long-term effects on the individual\u2019s life-history. For populations living in a fluctuating environment, the early life can be especially important, as it has the potential of preparing an individual to its future environment. Even though research on the effects of a specific early life environment is growing, there has not been much focus on the long-term consequences of male individuals. In this thesis, I used the bank vole (Myodes glareolus) as a model species to investigate the effects of an adverse early life environment on adult male offspring phenotype and fitness. Bank voles living in Fennoscandia experience population density fluctuations, and food and encounters with conspecifics are expected to be higher during population density peaks. This situation was simulated by conducting a two by two factorial design which exposed pregnant and nursing mothers to one or two ecologically relevant treatments, protein restriction and social confrontation, thereby changing the offspring\u2019s early life environment. Offspring did not receive any treatment after this pre- and early postnatal period and effects on offspring body mass, behaviour and fitness were assessed. Protein restriction had a negative effect on male adult body mass and both protein restriction and social confrontation altered male behaviour. The early life environment did not have an effect on female preference nor male reproductive success. In conclusion, while the early life of male bank voles had significant effects on their morphology and behaviour, this did not affect the individual fitness. Reproductive success is only one aspect of an individual\u2019s fitness and further research should be done on how the early life environment might affect other fitness related traits, such as survival.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Paivi Vuorio (paelvuor@jyu.fi) on 2021-01-18T07:42:23Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2021-01-18T07:42:23Z (GMT).
