- Postnatal development of diving physiology: implications of anthropogenic disturbance for immature marine mammals
Summary: Large oxygen reserves and oxygen-conserving mechanisms that support diving are underdeveloped at birth in pinnipeds and cetaceans. This Review explores how underdeveloped physiology makes immature marine mammals vulnerable to disturbance.
- Behavioral responses of individual blue whales (Balaenoptera musculus) to mid-frequency military sonar
Highlighted Article: Controlled exposure experiments using simulated mid-frequency sonar and pseudo-random noise revealed individual variation in behavioral responses of blue whales. Responses depended on contextual factors, including behavioral state, proximity and prey.
- Echo-acoustic flow affects flight in bats
Summary: Sensory flow is a ubiquitous principle for flight guidance, independent of the fundamentally different peripheral representation of flow across the senses of vision and echolocation.
- On doing two things at once: dolphin brain and nose coordinate sonar clicks, buzzes and emotional squeals with social sounds during fish capture
Summary: Dolphins use sonar to hunt fish; they make different sounds and different decisions simultaneously.
