Marine mammal recovery is associated with the resurgence of a nematode parasite. [PDF]
EcologyAbstract As the oceans change, the abundance of parasites and the risk of infection to marine mammals may also be changing. Nematodes in the family Anisakidae can harm marine mammals, and recent studies have revealed a global increase in these parasites, but the cause is unknown.

Frontiers in Marine Science, 2022 A key aspect of foraging ecology research is understanding how predator foraging behavior and success are influenced by variation in prey resources. For northern fur seals (Callorhinus ursinus), an understanding of predator-prey relationships is critical

Acute Gastric Dilatation with Volvulus in a Northern Fur Seal (Callorhinus ursinus) [PDF]
Journal of Wildlife Diseases, 1996 Acute gastric dilatation with volvulus occurred in a 4-year-old female northern fur seal (Callorhinus ursinus). The animal had been maintained in an outdoor exhibit at Mystic Marinelife Aquarium (Mystic, Connecticut, USA) from June 1989 to March 1994. On necropsy, we observed a 360 degrees clockwise rotation of the stomach about its mesenteric axis as ...

Linking reproduction and survival can improve model estimates of vital rates derived from limited time-series counts of pinnipeds and other species. [PDF]
PLoS ONE, 2013 We propose a method to model the physiological link between somatic survival and reproductive output that reduces the number of parameters that need to be estimated by models designed to determine combinations of birth and death rates that produce ...
