[08/2021] New paper out in iScience with the great team from Bioacoustics Aarhus: Wild bats briefly decouple sound production from wingbeats to increase sensory flow during prey captures

[06/2021] Holger receives a 5-year DFG Heisenberg Fellowship and a DFG research grant for two PhD students, to investigate interspecific acoustic communication networks and sensory-behavioural algorithms in predator-prey-interactions.

[06/2021] Congratulations Dr. Thejasvi Beleyur! Thejasvi has successfully defended his PhD thesis on "Theoretical and empirical investigation of echolocation in bat groups". And congrats for receiving funding to continue this work as PostDoc in collaboration with Iain Couzin and the Centre for the Advanced Study of Collective Behaviour in Konstanz.

[03/2021] Out in Mammal Review: the limits of acoustic monitoring of bats at wind turbines, and how to improve it. Summarized in this science communication animation.

[03/2021] Hot off the press in Science Advances with amazing colleagues from Bioacoustics Aarhus: Miniature tags reveal how free-flying hunting bats adjust both echolocation and flight to perceptually zoom-in on prey echoes and to reject background echoes.

[01/2021] Daniel's new paper is now out in J Exp Biol, showing task-dependent vocal adjustments in barbastelle bats across four different tasks of varying sensory-motor difficulty.

[01/2021] Two new papers accepted with international colleagues, on bioacoustic monitoring of bats at wind facilities (Mammal Review), and on biologging the sensory input of free-flying wild bats during foraging (Science Advances).

[12/2021] Dylan's new paper is now out in PeerJ, showing that only some bats can cope with noise-induced masking and distraction.

[11/2020] Two new papers accepted, congrats to Daniel and Dylan! More details on "task-dependent vocal adjustments" and on "coping with noise" soon to come in J Exp Biol and in PeerJ.

[11/2020] Our new paper and Theresa’s blog post in Ecology & Evolution: we suggest that light pollution suppresses both types of evasive flight in moths, making them easy prey for bats.

[07/2020] Very excited that Leonie Baier is joining us again, together with Eva Mardus! Welcome to both! Together, we will compare flight and echolocation behaviour in hearing-impaired and normal-hearing bats.

[06/2020] Our research is featured in the upcoming issue of MaxPlanckResearch and with an interview of Holger in the “Forschungsquartett” about sound on, the weekly podcast of the Max Planck Society.

[06/2020] Big congrats to Dr. Theresa Hügel, who has successfully defended her PhD thesis on “The sensory biology of evasive flight in eared moths”!

[02/2020] Congrats, Léna, for successfully defending her MSc-thesis on the effects of the daily variation in atmospheric conditions on echolocation call parameters!

[12/2019] Out now in PNAS: Modeling active sensing reveals echo detection even in large groups of bats, despite all the loud masking calls of neighbouring bats. Bats detect mostly echoes of their closest and frontal neighbours. This spatial limitation might be beneficial for following their neighbours during emergence.

[11/2019] Out now in J Theor Biol: Neural representation of bat predation risk and evasive flight in moths: a modelling approach. Combining empirical neuronal data of 12 moth species and flight path modelling of the sympatric community of those moths and their 14 predatory bat species, we show that even simple ears can solve complex problems.

[11/2019] Goodbye Aiqing! Aiqing Lin returned to his lab at the Northeast Normal University, China, after spending one year with us as Visiting Scholar.

[11/2019] Just accepted: Two papers, in which we modelled echo detection and auditory interactions in large bat swarms (Beleyur & Goerlitz, PNAS), and the evasive flight of eared moths based on auditory neuronal activity (Goerlitz et al, J Theor Biol)!

[10/2019] Just published in Global Ecology and Conservation: "Supposedly bat-friendly light colours like amber and red have negative effects on multiple bat species in caves and during emergence."

[10/2019] Our paper on Social Information Transfer featured as "In Focus" Article and on the Cover of the Journal of Animal Ecology.

[09/2019] Goodbye Daniel! Daniel started a new position at the Institute for Zoo and Wildlife Research after his PostDoc with us (watch out for those papers to come!). All the best, and see you soon!

[07/2019] Holger presented the group's research with invited lectures at the yearly meeting of Emmy Noether grantees and at the open door day of Castle Ringberg of the Max Planck Society.

[07/2019] Theresa's new study is out in Functional Ecology, showing that moth species perform species-specific escape flights in response to the same simulated bat attack. This variability increases the population-wide unpredictability, likely protecting moths further against their predators. Also see our press release.

[06/2019] Just published: Our research in the Research Highlights of the Yearbook 2018. Holger Goerlitz’s report about predator-prey-interactions for the Max Planck Yearbook 2018 was chosen as one of the 15 Highlights of the Max Planck Society 2018.

[06/2019] Holger R. Goerlitz received a new grant of the Emmy Noether program to continue for another year his research into the sensory strategies underlying predator-prey-interactions. This project will focus on prey selection strategies of echolocating bats, and predator-defence strategies of conspicuously singing male bushcrickets.

[04/2019] Three new papers out this week! Leonie's last PhD chapter shows that echolocation uses similar cues as vision for spatial feature analysis (iScience). Daniel's extensive field work reveals ubiquitous information transfer among insectivorous bat species (J Anim Ecol). And lastly a robust method for the self-calibration of microphone arrays based on a single sound playback by our colleagues in Lund (IEEE Xplore).

[03/2019] Welcome to Léna de Framond-Benard, starting her MSc thesis on dynamic adaptive echolocation in response to environmental changes. And goodbye to Paula Iturralde-Pólit, heading back to Costa Rica for field work!

[12/2018] Welcome back Toni Hubancheva! Toni is back from Bulgaria to analyse data of the last field season, conduct further experiments, and prepare the next field season. A busy winter before she will be heading back to our field station!

[11/2018] Welcome to Dr. Aiqing Lin, visiting us for one year from the Northeast Normal University, China.

[11/2018] Resource ephemerality drives social foraging in five species of bats: Our new paper by Egert-Berg, Hurme, Greif and an excellent international team driven by Yossi Yovel's lab, is out in Current Biology.

[10/2018] Welcome back Paula Iturralde-Pólit from Gloriana Chaverri's lab! Paula joins us again to analyse bat flight trajectories and call levels.

[09/2018] Welcome Neetash Mysuru, helping us to analyse the flight and echolocation behaviour of horseshoe bat aggregations.

[09/2018] September marks the end of a busy field season. Everyone's back in the lab now, and multiple papers are in preparation for the coming months.

[07/2018] Congratulations to Thejasvi for winning one year of funding from the DAAD!
