SOUND COMMUNICATION AND BEHAVIOUR GROUP

It is with great sadness that we learned that our beloved colleague and friend Annemarie Surlykke passed away on the 28th of July 2015. You can read an obituary here.

Professor Annemarie Surlykke focuses on sound production and echolocation in bats. Recently her focus has been on the intensity and directivity of the emitted sonar call and the implications for the way bats perceive the world through sound as well as their acoustic interaction with prey.

You can read more about her research in her own webpage www.batlab.dk

 

And you can find Annemarie Surlykke publications here (selection) and here (full list).

 

In our lab we study the sensory physiology and behavioral ecology of mainly bats with special focus on how they use and produce sound to navigate, find food, avoid predators and communicate.

 

Main focus areas of our research are for instance how echolocation signals correlate to size of animals (Jakobsen et al. 2013, Nature); how do intensity and directionality of echolocation signals vary according to the morphology of face and ear of bats (Brinkløv et al. 2011, JASA, Surlykke et al. 2013, Frontiers in Physiology), conspecifics or habitat; how can we infer about auditory scene analysis from echolocation (Moss et al. 2011, Curr Opin Neurobiol).

 

We compare as well bisonar of bats and whales (Madsen & Surlykke, 2013, Physiology). We study the interaction with bats’ insect prey (ter Hofstedte et al. 2013, J exp Biol) and hearing and sound production in other animals. We also participate in applied projects: we are developing new methods for long term surveys of bats (Andreassen et al. 2014 Ecol Inform) and we are involved in construction of biomimetic robots (www.chiroping.org )

 

Postdoc Signe Brinkløv - I study the bioacoustics, behavioral ecology and sensory biology of echolocators, using the very different echolocation systems of bats and birds as primary model systems.

My PhD focused chiefly on emitter aspects, namely, using microphone arrays to estimate the intensity and directionality of echolocation signals from Neotropical phyllostomid bats and reveal how those signals are adapted to foraging habitat.

You can read more about my research here.

Postdoc Lasse Jakobsen - studies the acoustic view of bats, their echolocation intensity, directionality, plasticity, and how body and environment constrains their biosonar.

You can find Lasse Jacobsen's publications here.

PhD student Katrine Hulgard - studies “Echolocating bats: a unique model for studying the importance of attention for hearing”. You can read more about the project here.

PhD student Clément Cechetto - studies "Multimodal integration in echolocating bats". You can read more about the project here.

PhD student Mads Nedergaard Olsen - studies "Multi agent behaviour of navigating groups".

 

Former (recent) Ph.d. students:

 

Kayleigh Fawcett - Graduated February, 2014 with the thesis: “ The influence of conspecifics and other interference on bat echolocation call design”.

 

Torúr Andreassen - Graduated October, 2013 with the thesis: ” Ultrasonic microphone arrays”.
