High Arctic “hotspots” for sperm whales (Physeter macrocephalus) off western and northern Svalbard, Norway, revealed by multi-year Passive Acoustic Monitoring (PAM)

Scientific Reports
Despite the well-documented, broad global distribution of sperm whales (Physeter macrocephalus), their distributional patterns remain poorly known in Arctic regions, where year-round monitoring is challenging. Adult male sperm whales are known to migrate

Influence of natural factors and anthropogenic stressors on sperm whale foraging effort and success at high latitudes

, 2015
Behavioural responses can reveal important fitness trade-offs and ecological traps in evolutionarily novel contexts created by anthropogenic stimuli, and are of increasing conservation concern due to possible links to population-level impacts.

Vertebral bone microarchitecture and osteocyte characteristics of three toothed whale species with varying diving behaviour

Scientific Reports, 2017
Although vertebral bone microarchitecture has been studied in various tetrapods, limited quantitative data are available on the structural and compositional changes of vertebrae in marine mammals. Whales exhibit exceptional swimming and diving behaviour,

Click-click, who’s there? Acoustically derived estimates of sperm whale size distribution off western Ireland

Frontiers in Marine Science
Understanding the structure of populations is a critical element to the establishment of management and conservation measures. Sperm whales Physeter macrocephalus are characterised by a demographic spatial segregation, associated with a conspicuous ...

The use of active sonar to study cetaceans

, 2012
Cetacean species face serious challenges worldwide due to the increasing noise pollution brought to their environment by human activities such as seismic exploration. Regulation of these activities is vaguely defined and uncoordinated.

No evidence for recovery in the population of sperm whale bulls off Western Australia, 30 years post-whaling

Endangered Species Research, 2014
The global sperm whale Physeter macrocephalus population has been protected from large-scale commercial whaling for >25 yr, yet there is no clear evidence of recovery in any heavily exploited stock.
