Marine mammal noise exposure criteria: Initial scientific recommendations.
An expert panel reviewed the expanding literature on marine mammal (cetacean and pinniped) auditory and behavioral responses to sound exposure to develop comprehensive, scientifically based noise
Marine Mammal Noise Exposure Criteria: Updated Scientific Recommendations for Residual Hearing Effects
sources, exposure criteria are given in frequencyweighted sound exposure level (SEL, given in This article evaluates Southall et al. (2007) in light units relative to 1 μPa-s or (20 μPa)-s for water
Measuring hearing in the harbor seal (Phoca vitulina): comparison of behavioral and auditory brainstem response techniques.
TLDR
Comparisons of ABR and behavioral methods performed in other recent studies indicate that ABR methods represent a good alternative for estimating hearing range and sensitivity in pinnipeds, particularly when time is a critical factor and animals are untrained.
Acoustic characteristics of ultrasonic coded transmitters for fishery applications: could marine mammals hear them?
TLDR
Based on propagation models and published data on marine mammal auditory psychophysics, harbor seals potentially could detect the VEMCO 69 kHz UCTs at ranges between 19 and >200 m, while odontocetes potentially could detection them at much greater ranges.
Behavioral Responses and Habituation of Pinnipeds and Small Cetaceans to Novel Objects and Simulated Fishing Gear With and Without a Pinger
TLDR
It is more likely that pingers reduce entanglement by arousing aversion than by warning marine mammals to avoid a hazard.
Impacts of acute and long-term vehicle exposure on physiology and reproductive success of the northern spotted owl
TLDR
Examining the effects of off-highway vehicle use on the federally threatened northern spotted owl, Strix occidentalis caurina, by measuring fecal glucocorticoid metabolites, which reflect disturbance; fecal thyroid hormone metabolites (fT3), which reflect nutrition; and the number of offspring fledged within a season reveals vulnerability to disturbance in a free-living species.
Animal vocal sequences: not the Markov chains we thought they were
TLDR
It is suggested that non-Markovian vocal sequences may be more common than Markov sequences, which must be taken into account when evaluating alternative hypotheses for the evolution of signalling complexity, and perhaps human language origins.
Relative abundance and behavior of marine mammals exposed to transmissions from the Heard Island Feasibility Test.
TLDR
The Heard Island Feasibility Test source transmitted a hum at 209-220 dB re: 1 microPa at 175-m depth, centered on 57 Hz with a maximum bandwidth of 30 Hz for 1 h of every 3.5 minutes, and both species were heard within 48 h after the end of the test.
Auditory evoked potentials in two short-finned pilot whales (Globicephala macrorhynchus).
TLDR
The hearing sensitivities of two short-finned pilot whales were investigated by measuring auditory evoked potentials generated in response to clicks and sinusoidal amplitude modulated (SAM) tones.
