Leibniz-IZW-Seminare

Das Leibniz-Institut für Zoo-und Wildtierforschung veranstaltet regelmäßig wissenschaftliche Vorträge zu verschiedenen Themen, in denen eingeladene Rednerinnen und Redner oder IZW-Wissenschaftlerinnen und IZW-Wissenschaftler ihre Arbeit in Form eines Vortrags vorstellen. Die kostenfreien Veranstaltungen finden im Hörsaal des IZW statt und werden auch live per Video übertragen.
Interessierte Personen sind herzlich eingeladen die Leibniz-IZW-Seminare persönlich oder online zu besuchen. Sie können sich gerne unter izwseminar@izw-berlin.de für unseren Newsletter anmelden. Die Vorträge werden größtenteils auf Englisch gehalten.

Infant presence and mother-infant conflict predict fetal loss in wild mandrills
Fitness is shaped by the pace of reproduction and the trade-offs in parental investment allocated between current and future offspring. Using a comprehensive 11-year longitudinal dataset comprising 362 pregnancies from 117 wild female mandrills (Mandrillus sphinx), we investigated how reproductive strategies influence maternal investment decisions and their consequences for both current and future reproductive outcomes. Our findings reveal that when females shift investment away from current infant care to prioritize a new gestation, they face elevated mother-infant behavioral conflict. This conflict significantly increases the likelihood of fetal loss, thereby reducing short-term reproductive success. The mother-infant conflict appears to act as a physiological or behavioral barrier to efficiently reallocating maternal resources toward the developing fetus. Alternatively, it may trigger a strategic termination of pregnancy, serving as an adaptive response to mitigate the fitness costs associated with short inter-birth intervals, such as the risk of losing a dependent infant. Notably, females who experienced fetal loss subsequently demonstrated higher long-term reproductive success compared to those who carried an infant to term but whose offspring died at a young age. These results uncover a previously hidden adaptive mechanism that appears to regulate the timing of female reproduction in a way that maximizes lifetime fitness. I will talk about this one article - scheduled to be published on November 3rd.
