Contextual and combinatorial structure in sperm whale vocalisations [PDF]
Sperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, almost everything else about the sperm whale ...

Beached bachelors: An extensive study on the largest recorded sperm whale Physeter macrocephalus mortality event in the North Sea. [PDF]
Between the 8th January and the 25th February 2016, the largest sperm whale Physeter macrocephalus mortality event ever recorded in the North Sea occurred with 30 sperm whales stranding in five countries within six weeks.

The departure of sperm whales (Physeter macrocephalus) in response to the declining jumbo squid (Dosidicus gigas) population in the central portion of the Gulf of California [PDF]
As sperm whales are important predators that control energy flux in the oceans, changes in their population can be used as a sentinel to measure of ecosystem health.

Echolocation repetition rate as a proxy to monitor population structure and dynamics of sperm whales
Passive acoustic monitoring is an essential method for studying the ecology of endangered sperm whales. We present a novel approach based on their sexual body size dimorphism to monitor population structure and dynamics by using the time interval between echolocation clicks (ICI) as a proxy for body length. Our results suggest that ICI can be used as a

Exploring variability in the diet of depredating sperm whales in the Gulf of Alaska through stable isotope analysis [PDF]
Sperm whales interact with commercially important groundfish fisheries offshore in the Gulf of Alaska (GOA). This study aims to use stable isotope analysis to better understand the trophic variability of sperm whales and their potential prey, and to use ...

Wild whale faecal samples as a proxy of anthropogenic impact
The occurrence of protozoan parasite, bacterial communities, organic pollutants and heavy metals was investigated in free-ranging species of fin (Balaenoptera physalus, n. 2) and sperm (Physeter macrocephalus, n.

Sperm whale presence observed using passive acoustic monitoring from gliders of opportunity
Habitat use by the endangered Mediterranean sperm whale subpopulation remains poorly understood, especially in winter. The sustained presence of oceanographic autonomous underwater vehicles in the area presents an opportunity to improve observation ...

Conformity in mate choice, the overlooked social component of animal and human culture
ABSTRACT Although conformity as a major driver for human cultural evolution is a well‐accepted and intensely studied phenomenon, its importance for non‐human animal culture has been largely overlooked until recently. This limited for decades the possibility of studying the roots of human culture.

The Mediterranean sperm whale population, Physeter macrocephalus, is listed as endangered due to population decline caused by human activities. To mitigate the impact of these activities, accurate knowledge of their distribution and abundance is crucial.
