Ecological niches of three teuthophageous odontocetes in the northwestern Mediterranean Sea [PDF]
Ocean Science, 2008 In the northwestern Mediterranean Sea, sperm whales, pilot whales and Risso's dolphins prey exclusively or preferentially on cephalopods. In order to evaluate their competition, we modelled their habitat suitability with the Ecological Niche Factor ...

Cultural turnover among Galápagos sperm whales [PDF]
Royal Society Open Science, 2016 While populations may wax and wane, it is rare for an entire population to be replaced by a completely different set of individuals. We document the large-scale relocation of cultural groups of sperm whale off the Galápagos Islands, in which two sympatric vocal clans were entirely replaced by two different ones.

Marine Mammal Science, EarlyView.Abstract The sperm whale (Physeter macrocephalus) is one of the most widely distributed cetaceans. Adult males commonly occupy high latitudes, whereas females and juveniles occupy lower latitudes. In Northern Norway, previous studies focused on the summer period limiting our understanding of the seasonal dynamics of male foraging aggregations.

A machine-learning approach to assign species to ‘unidentified’ entangled whales
Endangered Species Research, 2018 Whale entanglements in US west coast fishing gear are largely represented by opportunistic sightings, and some reports lack species identifications due to rough seas, distance from whales, or a lack of cetacean identification expertise.

Regular Presence of Harbor Porpoises in the Northern Alborán Sea
Marine Mammal Science, EarlyView.ABSTRACT The harbor porpoise (Phocoena phocoena) in the Atlantic waters of Spain and Portugal are a genetically differentiated population from the rest of the North Atlantic. They are rarely seen on the southern Atlantic coast of Spain and are thought to be extinct in the Mediterranean Sea, with scattered sightings and strandings recorded along the ...

An update on pacemaking in the myometrium
The Journal of Physiology, EarlyView.Abstract figure legend The spread of multiple electrical signals (panel A, blue‐to‐red indicates increasing electrical excitability) that are spatiotemporally distinct, yet in‐phase with the excitatory episode, determines action potential shape and form (panel B, as recorded by single cell microelectrodes) and ensures contractile amplitude and duration

The Anatomical Record, Volume 308, Issue 4, Page 1265-1277, April 2025.Abstract Muscle is a complex tissue that has been studied on numerous hierarchical levels: from gross descriptions of muscle organization to cellular analyses of fiber profiles. In the middle of this space between organismal and cellular biology lies muscle architecture, the level at which functional correlations between a muscle's internal fiber ...
