Thank you so much Cedric! It was an honor to have you on my examination board 👩🏼‍🎓

Diandra Duengen @diandraduengen.bsky.social · 1d

This special day was filled with a huge bag of mixed feelings, from excitement to nervousness, happiness to anxiety, from the eagerness to answer the opponent's questions to the curiosity of further elaborating on research over dinner. It was an amazing day, and I thank all of you who participated 🎊

I am so thankful for my supervisors @andrearavignani.bsky.social and @profsimonfisher.bsky.social for their guidance and encouragement throughout the past years. Without them, none of this would have been possible, I call myself lucky to having been their PhD student.

I am mind blown to announce that the day before yesterday I have been awarded the degree of doctor from Radboud University, Nijmegen, with the distinction cum laude, which I learned is the highest distinction in the Netherlands 🤯👩🏼‍🎓
That my thesis was honored in this way really moves me.

New preprint in collaboration with @babeheim.bsky.social: Vocal mimicry in corvids. We describe vocal mimicry, i.e., copying of sounds produced by another species or the environment, in 31 out of 128 corvid species (24%). (1/2)

🐀 ultrasonic vocalizations be wildin' 🐀

@nicolasmathevon.bsky.social etc al. use @openacousticdevices.info to study how striped mice use USVs in the wild, new in @currentbiology.bsky.social

See graphical abstract for summary of results (does the work for us 😇) 👇

#bioacoustics
#prattle 💬

Graphical abstract from paper in quoted post

Top panel depicts modulation of vocal repertoire use depending on territorial location

Next panel depicts group& specific information embedded in ultrasonic vocalizations

Bottom panel shows that individuals use this information to adapt their behavioral and vocal response. No behavioral change to groupmate playback, increased vigilance and vocal response to neighbor playback, and in addition to increased vigilance/response, retreat to nest in response to stranger playback

You’re now breathing manually 🌬️

What underlies this ability to be consciously aware of own breathing?

In our new Journal of Neuroscience paper, we report the largest study to date linking brain microstructure to respiratory interoception.

Interoception, the perception and integration of physiological signals, is a fundamental aspect of self-awareness and homeostasis. While previous work has explored interoceptive processing in the card...

Curious about vocal learning in pinnipeds? Come meet me at my poster at #IBAC2025 today and tomorrow 1 - 3.30 pm, and hear about my newest research on phonatory control in gray seal sound production 🦭🦭 looking forward to seeing you there!

Elephants show different levels of complexity in vocal usage learning, as well as vocal production learning - exemplified by their ability to imitate human speech. Great presentation of this fascinating trait in elephants @angelastoeger.bsky.social at #IBAC2025. Amazing work and very enjoyable talk!

For this, we trained the seal to adjust his vocalizations' duration via operant conditioning, reinforcing both short and long durations in separate sessions - this led to the emergence of vocalizations as short as 79 ms, and as long as 9.23 seconds...

Diandra Duengen @diandraduengen.bsky.social · Sep 10

... to find out how we implemented a semi-automatical setup to live-track the seal's vocalizations, read the whole research article in BMC Ecology & Evolution. This work was conducted through @mpi-nl.bsky.social, together with Yannick Jadoul & @andrearavignani.bsky.social.

Check out our new paper on a male harbor seal's 🦭 excellent respiratory control: within just a few weeks, this young seal learned to produce vocalizations that spanned over two orders of magnitude in duration! ...

"Findings suggest that compositionality [the capacity to combine meaningful elements into larger meaningful structures] is a prominent feature of the bonobo vocal system revealing stronger parallels with human language than previously thought." Fascinating work by @berthetmelissa.bsky.social et al.🧪
