Variation in human secondary sex ratio after extraordinary natural, social and cultural events
Hubová, Hana ; Kaňková, Šárka (advisor) ; Dušek, Adam (referee)
The secondary sex ratio represents the proportion of male and female births and is usually slightly skewed towards male births. Changes in the secondary sex ratio may be induced by a variety of ultimate (evolutionary) or proximate (physiological) causes. These causes tend to be linked to external factors such as natural disasters, armed conflicts, terrorism and/or important cultural and sports events. Natural disasters cause major destruction of housing, infrastructure and loss of lives. Such events are likely to be followed by a decrease in the secondary sex ratio. Stress-induced selection in utero against males is one of the widely discussed causes related to this phenomenon. Armed conflicts and terrorism commonly have a negative impact on society as well, however, an increase in the secondary sex ratio was often observed in the post-war periods. Important cultural and sports events, along with holiday celebrations, have a mostly positive impact on the social climate. These events induce a sense of community and are likely to be followed by an increase in the secondary sex ratio 9 months later, which suggests higher coital rates during such events.
