Eva Ringler 2 studied biology and mathematics (curriculum for high school teaching) at the University of Vienna (2002-2007). Afterwards she started her doctorate studies in Zoology at the University of Vienna.

In the course of her research activities she has been travelling to Costa Rica, French Guiana, Great Britain, Indonesia, and to the United States. During her PhD she investigated the mating system and parameters of reproductive success in a natural poison frog population in French Guiana.

After gaining her PhD with distinction in 2011, she successfully applied for a stand-alone project from the Austrian Science Fund (FWF). This project focuses on „Determinants of fitness in species with complex life cycles“. In the course of this project Ringler and her team managed to establish an “artificial” frog population on a river island in French Guiana, as well as a controlled ex-situ laboratory frog population at the University of Vienna. Since February 2015 she is member of the Messerli Research Institute and currently holds a Hertha-Firnberg post-doc fellowship by the FWF.



Max Ringler (co-leader) uses GIS analyses and bioacoustics to study ecology and ethology of Neotropical frogs. Together with Eva he has established the experimental river island population in French Guiana, as well as the laboratory population at the University of Vienna.

Walter Hödl is officially retired, but still a very active professor at the Department of Integrative Zoology at the University of Vienna. For more than 20 years and in cooperation with numerous international co-workers he has established Allobates femoralis as a model organism for bioacoustics, biogeography, and ethological, ecological and evolutionary research.

Andrius Pašukonis is a passionate field biologist interested in behavior and cognition of tropical frogs. He is particularly fascinated with poison frogs because they display some of the most complex spatial and social behaviors known among amphibians. He mainly uses tracking, frog translocations, and extensive observations to study their movement patterns, learning abilities, and navigation mechanisms in the field.
