Mark Johnson

Aarhus University, Denmark​

Mark Johnson is an electronics engineer with a strong interest in animal biology. His engineering focus is in developing instruments and data processing techniques for studying animals in the wild. His biological interests are in sensory ecology, foraging, and predator-prey interactions primarily in the marine environment. To explore the behaviour of wild animals, he has developed highly integrated multi-sensor data loggers such as the DTAG. These tags have been applied to animals from more than 30 species yielding insights into foraging and social behaviour as well as the effects of human disturbance, and are being used in the CCAS project to study spotted hyenas.

Vlad Demartsev

University of Konstanz & Max Planck Institute of Animal Behavior, Germany

Vlad is a behavioural ecologist with a strong preference for field-based, experimental work. He is generally interested in mammalian vocal communication, especially in the coordination of signalling within a group and in the dynamics of continuous signalling interactions over time. His research within the CCAS project focuses on meerkats.

Eli Strauss

Michigan State University, USA & Max Planck Institute of Animal Behavior, Germany

Eli is a postdoc at the Max Planck Institute of Animal Behavior. In this project, Eli is using conventional and remotely-sensed data on social interactions of spotted hyenas (e.g., aggressive or affiliative behaviors) to understand how social relationships influence fission-fusion dynamics and, conversely, how patterns of space use influence the way individuals experience their societies.

Baptiste Averly

University of Konstanz & Max Planck Institute of Animal Behavior, Germany

Baptiste worked as a PhD student from 2018-2022 on the link between communication and collective movement in meerkats. To tackle this topic, he collected high resolution acoustic and spatial data of wild habituated meerkat groups using custom-made collars, and analyzed the resulting tracking data to understand how influence is distributed within meerkat groups.
