Master thesis on contracepted animals in zoos: Congratulations to Catalina Manduta

Today Species360 Conservation Science Alliance student Catalina Manduta successfully defended her Master thesis at the University of Southern Denmark. Catalina presented her work on survival differences in contracepted versus non-contracepted animals in zoos.

She showed that surgical contraception in male mammals lead to an increase in life expectancy for nearly 80% of species, and explored different evolutionary hypotheses that can explain these differences. She particularly analysed the cost of reproduction hypothesis, which postulates that internal energy resources are finite, leading to a trade-off between reproduction and survival, thus potentially leading to a survival advantage in castrated individuals. However, her results could not confirm this hypothesis.
