Long-term associations among male sperm whales (Physeter macrocephalus).
PLoS ONE, 2020 Little is known about the social structure of male sperm whales (Physeter macrocephalus) after they leave their natal units. While previous studies found no evidence for preferred associations among males, the observation of mass-strandings consisting ...

Contamination in Reference Sequence Databases: Time for Divide-and-Rule Tactics
Frontiers in Microbiology, 2021 Contaminating sequences in public genome databases is a pervasive issue with potentially far-reaching consequences. This problem has attracted much attention in the recent literature and many different tools are now available to detect contaminants ...

Back to Water: Signature of Adaptive Evolution in Cetacean Mitochondrial tRNAs [PDF]
, 2016 The mitochondrion is the power plant of the eukaryotic cell, and tRNAs are the fundamental components of its translational machinery. In the present paper, the evolution of mitochondrial tRNAs was investigated in the Cetacea, a clade of Cetartiodactyla ...

A survey of the sperm whale (Physeter catodon) commensal microbiome [PDF]
PeerJ, 2019 Background Mammalian commensal microbiota play important roles in the health of its host. In comparison to terrestrial mammals, commensal microbiota of marine mammals is mainly focused on the composition and function of skin and gut microbiota, with less

Occurrence of sperm whale (Physeter macrocephalus) in the Russian Arctic
Polar Research, 2020 We report two sperm whale (Physeter macrocephalus) strandings observed in the south-east corner of the Barents Sea (i.e., Pechora Sea) in 2018, unusually far from the species’ hitherto known distribution.

Male sperm whale acoustic behavior observed from multipaths at a single hydrophone [PDF]
, 2005 Sperm whales generate transient sounds (clicks) when foraging. These clicks have been described as echolocation sounds, a result of having measured the source level and the directionality of these signals and having extrapolated results from biosonar ...
