Chilean Dolphins (Cephalorhynchus eutropia) Produce Both Narrowband High‐Frequency and Broadband Clicks

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Most dolphin species produce broadband biosonar clicks for echolocating prey, and whistles and burst‐pulsed calls for communication purposes. Seven dolphin species were previously reported to only produce clicks of a narrowband high‐frequency (NBHF) type, very similar to the clicks produced by porpoises.

Mind the Gap: Performance Limits of Automated Contour Extraction Methods for Individual Monitoring of Bottlenose Dolphins

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Reliable extraction of dolphin whistle contours is fundamental for scalable analyses of vocal identity, repertoire structure, and individual‐based acoustic monitoring. We evaluated four algorithms for fundamental frequency estimation of common bottlenose dolphin (Tursiops truncatus) whistles, leveraging a benchmark dataset of annotated ...

The More the Merrier: The Effects of Data Volume and Transfer Learning on Creating Generalizable Deep Learning PAM Detectors

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Passive acoustic monitoring (PAM) generates large datasets that are costly to analyze manually, creating the need for accurate automated detection methods. While deep learning (DL) has shown promise for PAM‐related tasks, the transferability of trained models to unseen datasets remains a critical challenge.

Community Awareness and Evidence of Dugong (Dugong dugon) Presence in Anjouan, Comoros

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The dugong (Dugong dugon), listed as Vulnerable globally, is poorly documented in the Western Indian Ocean, including the Comoros. We combined Local Ecological Knowledge (LEK) and Passive Acoustic Monitoring (PAM) to assess occurrence and reported encounters around the island of Anjouan.

Classification of Bering‐Chukchi‐Beaufort Bowhead Whale Calls

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Bowhead whales (Balaena mysticetus) are an endemic species to the Arctic Ocean and are highly reliant upon acoustic communication. Despite being one of the most thoroughly studied populations of bowhead whales, we still have a poor understanding of the calling behavior of Bering‐Chukchi‐Beaufort (BCB) bowhead whales.

Sex‐Specific Responses to Social Calls Shape Foraging Decisions in a Nectar‐Feeding Bat

Annals of the New York Academy of Sciences, Volume 1564, Issue 1, October 2026.
Playback experiments in a nectar‐feeding bat revealed contrasting responses to the same vocalizations, thus demonstrating that it depends on the receiver how social information is interpreted. Alert calls, often produced in aggressive contexts, showed no detectable acoustic differences between sexes, yet elicited different responses in males and ...
