Female sperm storage is ubiquitous in the animal kingdom and it has been shown to be linked to several evolutionary processes, from postcopulatory sexual selection to dispersal. Here we report, for the first time, long-term sperm storage in females of the tardigrade Macrobiotus polonicus. Females, isolated after a short contact with a male, were able to use the stored sperm for up to 5 weeks (mean of 2 weeks), which translates to a considerable proportion of female post-mating longevity under controlled laboratory conditions (60% on average). Our study provides the first insights into the duration of sperm storage, an underexplored feature of the reproductive biology of tardigrades. Additionally, we discuss important considerations for reproductive studies on these non-model animals.

New insights on the role of ecology and life-history in social evolution Avila, Piret (University of Jyväskylä, 2017)Biological altruism, deﬁned as a behaviour that beneﬁts others at an apparent cost to the focal individual, is found abundantly across diﬀerent levels of biological organization. While kin selection has been useful for ...
Asymmetries in reproductive anatomy : insights from promiscuous songbirds Calhim, Sara; Pruett-Jones, Stephen; Webster, Michael S.; Rowe, Melissah (Oxford University Press, 2019)Directional asymmetry in gonad size is commonly observed in vertebrates and is particularly pronounced in birds, where the left testis is frequently larger than the right. The adaptive significance of directional asymmetry ...
Cost of reproduction and offspring quality in the evolution of reproductive effort 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 ...
