- Context-dependent biosonar adjustments during active target approaches in echolocating harbour porpoises
Highlighted Article: Porpoises performing target approaches adjust biosonar outputs and clicking rates differently depending on the environment, thus highlighting context as an important factor to consider in addition to range-dependent biosonar adjustments.
- Dolphin echolocation behaviour during active long-range target approaches
Summary: Echolocating dolphins can use three modes of range-dependent click rate adjustment during long-range target approaches, and adjust click intensity with range, but not to perceive constant echo levels.
- Amazon river dolphins (Inia geoffrensis) modify biosonar output level and directivity during prey interception in the wild
Summary: Wild Amazon river dolphins increase biosonar beamwidth and decrease source level during prey approach while click rates transition into a buzz phase at the time of prey capture.
- Amazon river dolphins (Inia geoffrensis) use a high-frequency short-range biosonar
Highlighted Article: Amazon river dolphins inhabit an acoustically complex habitat, where they employ a short-range biosonar with source parameters not predictable from body size alone, suggesting that habitat is an important evolutionary co-driver of toothed whale biosonar.
- Nitrogen solubility in odontocete blubber and mandibular fats in relation to lipid composition
Highlighted Article: Nitrogen solubility in toothed whale mandibular fats and blubber is related to lipid composition; most tissues exceed the fat nitrogen solubility value traditionally used in marine mammal gas dynamics models.
