In nature, animal vocalizations can provide crucial information about identity, including kinship and hierarchy. However, lab-based vocal behavior is typically studied during brief interactions between animals with no prior social relationship, and under environmental conditions with limited ethological relevance. Here, we address this gap by establishing long-term acoustic recordings from Mongolian gerbil families, a core social group that uses an array of sonic and ultrasonic vocalizations.

Many machine learning methods have emerged in recent years to make sense of complex video and neurophysiological data that result from these experiments. Less focus has been placed on understanding how animals process acoustic information, including social vocalizations.

- Animal vocalizations can convey critical information about identity, kinship, and social hierarchy, but previous studies often lack ecological relevance due to brief lab interactions.
- This study focused on Mongolian gerbil families and recorded their vocalizations continuously for 20 days, revealing a more complex vocal repertoire than previously known, with significant differences between families.
- The findings suggest the presence of family-specific vocal dialects, which highlights the gerbils as a valuable model for understanding vocal communication and the potential for using advanced machine learning techniques to analyze animal behavior in a naturalistic context.
Article Synopsis
- The study investigates the best strategy for transitioning mechanically ventilated patients from strict lung protective ventilation to patient-directed ventilation, weighing aggressive versus conservative approaches.
- Researchers analyzed data from 7,433 patients and found that aggressive strategies significantly expedited the first liberation attempt compared to conservative methods.
- While aggressive liberation increased the number of ICU-free and ventilator-free days, it had a minimal impact on overall mortality rates, but slightly elevated mortality risk in patients with high severity of illness.
