Bart J. A. Pollux

Bart J. A. Pollux is an Associate Professor at Wageningen University & Research in the Wageningen Institute of Animal Sciences, specializing in Experimental Zoology. His research focuses on evolutionary biology and physiology of live-bearing fishes, particularly examining placental development, maternal-offspring interactions, and predation ecology.

Dr. Pollux's research interests span evolutionary adaptations in fish reproductive strategies, with particular emphasis on placental development in Poeciliidae family fish. His work explores how predation pressure influences evolutionary trajectories, how maternal stress transfers to offspring through placental mechanisms, and the cognitive implications of mating behaviors in live-bearing fish species. His research bridges evolutionary biology, physiology, and behavioral ecology to understand fundamental biological processes.

His publication record demonstrates consistent contributions to understanding fish evolution, particularly in guppies and other live-bearing species. Recent work examines artificial selection for predation survival, maternal depression effects on offspring, and the invasion ecology of lionfish in the Mediterranean Sea. These studies reveal patterns connecting environmental pressures to morphological, physiological, and behavioral adaptations.

Dr. Pollux has received recognition through the Mosaic 2.0 grant/NWO, supporting collaborative research with PhD students. His work has generated significant academic interest, with multiple publications cited across various platforms and picked up by numerous news outlets.

As an academic advisor, Dr. Pollux supervises multiple PhD candidates working on projects related to placental transfer of maternal effects, lionfish invasion ecology, maternal immune tolerance, and the evolution of sexual selection. His research group actively collaborates with international partners across different ecological and biological disciplines.
