Despite the same pelvis-to-head ratio, Japanese macaques do not suffer the same birth complications as humans. An international research team led by the University of Vienna and the Medical University of Vienna has used long-term demographic data from Japanese macaques at the Affenberg Landskron to show that, unlike humans, there is no maternal mortality in these primates linked to childbirth. The results of the study were recently published in the renowned scientific journal PNAS. The team was also honored with the cover's image.

 Congratulations to Roy Hammer for receiving the Best Lightning Talk Award

The Affenberg Research Station Team attended the 10^th European Federation for Primatology meeting (EFP 2024) in Lausanne, Switzerland with several contributions. Big congratulations to Roy Hammer for his outstanding performance and winning the best Lightning Talk!

The latest interdisciplinary project that takes place at the Affenberg Research Station has been presented on the 21^st of March 2024. The Smart Monkey Lab, which is a cooperation between the University of Vienna, the Carinthian University of Applied Sciences (FH Kärnten) and the Affenberg, aims to develop new technological tools to support behavioural biological research as well as test the applicability of Citizen Science in these studies. Funded by the FFG Bridge Research Programme, this project will form the bridge between fundamental research, technological advancement and public engagement.

The Japanese macaque has become a key species for studying homosexual behavior over recent decades. With this study, we examined behavioral aspects underlying temporal patterns in female-female homosexual consortships. We hypothesized that the stability of consortships (duration and occurrence) is influenced by a pair’s sexual behavior, mutual sexual stimulation, and close affiliative inter-mount behaviors involving high-intensity body contact. The population of Japanese macaques at the Affenberg Landskron was observed over one mating season. Our analyses found that close body contact, rather than grooming or sexual interactions, was correlated with the stability of homosexual consortships.
