Ageing via perception costs of reproduction magnifies sexual selection.
2018
Understanding what factors modulate sexual selection intensity is crucial to a wide variety of evolutionary processes. Recent studies show that perception of sex pheromones can severely impact male mortality when it is not followed by mating (perception costs of reproduction). Here, we examine the idea that this may magnify sexual selection by further decreasing the fitness of males with inherently low mating success, hence increasing the opportunity for sexual selection. We use mathematical modelling to show that even modest mortality perception costs can significantly increase variability in male reproductive success under a wide range of demographic conditions. We then conduct a series …
Masters of their own time? Working carers’s visions about combining retirement and caring
2011
How do working careers anticipate the timing of retirement and the weight of care commitments related to other activities when retired? This question is discussed by analysing the experiences of Finnish working careers. Most of the interviewees indicated that helping parent(s) would be part of their own retirement, but after leaving full-time work they would also like to devote time for their other personal interests, too. Working careers are willing to engage in caring when retired. However, they also have a desire to outline their caring tasks and manage their own time. nonPeerReviewed
