High and minimally variable adult marine survival among multiple stocks of Chinook salmon
Ecosphere, Volume 17, Issue 9, September 2026.Abstract Estimates of individual survival across space and time provide critical information on processes that regulate population abundance. Here, we use state‐space models fit to data from more than 500 acoustically tagged Chinook salmon to better understand the factors that shape survival during the final summer and fall of marine residence—a life ...

Aquatic Biology, 2013 Three Steller sea lions Eumetopias jubatus, trained to dive voluntarily to depths ranging from 10 to 50 m, were used to determine whether the relationship between activity and metabolic rate during a diving interval (MRDI, dive + surface interval) was ...

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT As breath‐hold divers, marine mammals must coordinate their use of both aerobic and anaerobic metabolism to maximize their time at depth. One indication of the relative reliance between these two energy‐producing systems is the aerobic dive limit (ADL), defined as the dive duration where post‐dive blood lactate concentrations surpass resting ...

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT West Coast Transient (WCT) killer whales (Orcinus orca rectipinnus) hunt marine mammals along the west coast of North America from California to southeastern Alaska. However, little information is available on their seasonal use of nearshore areas and the relative importance of different parts of their range.

Spectrum, 2018 Habitat selection by species is dependent on both abiotic factors and species interaction. With regards to species interaction, competition and facilitation can play a critical role regarding how a species selects its habitat. Previous work has suggested

Marine Mammal Science, Volume 42, Issue 3, July 2026.ABSTRACT Seal haulout behavior is of interest in relation to energetics and abundance estimation. To assess year‐round and diel haulout patterns and estimate correction factors, data were obtained from 100 seals (66 harbor and 34 gray seals) tagged with satellite transmitters in Kattegat and the western Baltic Sea during 2004–2017.

Stable Isotope Analysis of New Zealand Fur Seal Vibrissae Shows Deceased Juveniles Were Weaned Early
New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.The New Zealand fur seal/kekeno (Arctocephalus forsteri, NZFS) is a marine predator native to Aotearoa/New Zealand. Little is known about its fine‐scale dispersal around New Zealand in the nonbreeding season. As an alternative to external marking or electronic tracking, stable isotope analysis was trialed to determine the origin of stranded (deceased ...

The diet and feeding ecology of harbour seals around Britain [PDF]
, 2015 Since 2000, there has been a marked decline in the number of harbour seals in some regions around Britain; one possible contributing cause is competition for prey with sympatric grey seals.
