"Is 40 the new 30? Increasing reproductive intentions and fertility rates beyond age 40 Éva Beaujouan and Tomáš Sobotka Acknowledgments: Eva Beaujouan's contribution was funded by the Austrian Science Fund (FWF), project 'Later Fertility in Europe' (Grant agreement no. P31171-G29); The Office for National Statistics provided access to the British General Household Survey series (originally constructed by the ESRC Centre for Population Change). Introduction Across the highly developed countries, reproduction trends of the last half a century are characterised by a continuous shift of parenthood towards higher reproductive ages (1- 3). The trend to later childbearing has been fuelled by a broad array of cultural and social changes such as higher education expansion, rise in gender equality and in women's employment, changes in partnership behaviour, rising economic uncertainty, and shifts in family-related values and attitudes (e.g. 4). Late reproduction has progressed hand in hand with a trend to a smaller family size, with two-child families becoming most prominent with respect to both fertility ideals and actual family size (5,6)"--

The study of alternative reproductive tactics (the behavioural strategies used by individuals to increase their reproductive success) is an evolutionary puzzle, and one of great interest to researchers. For instance, why do some males guard both nest and eggs, while others sneak into nests while pairs are spawning and fertilise those eggs? The field offers a special opportunity to study the evolution and functional causes of phenotypic variation, which is a general problem in the field of evolutionary biology. By integrating both mechanistic (psychological) and evolutionary (behavioural ecology) perspectives and by covering a great diversity of species, Alternative Reproductive Tactics addresses this integrated topic of longstanding interest, bringing together a multitude of otherwise scattered information in an accessible form that is ideal for graduate students and researchers.
