Spatial and seasonal relationships between Pacific harbor seals (Phoca vitulina richardii) and their prey, at multiple scales [PDF]

open access: yes, 2009
Knowing where pinnipeds forage is vital to managing and protecting their populations, and for assessing potential interactions with fisheries. We assessed the spatial relationship between the seasonal distribution of Pacific harbor seals (Phoca vitulina

Possible effects of climate change on the populations of Galapagos pinnipeds [PDF]

open access: yes, 2010
The future of Galapagos Sea Lion Zalophus wollebaeki and Galapagos Fur Seal Arctocephalus galapagoensis populations was evaluated with reference to a conservative model of predicted climate change.

Accuracy and precision of an umbilical‐based method for estimating birthdates of pre‐weaned harbour seal pups

open access: yesWildlife Society Bulletin
Fine‐scale age estimation of animals can provide insight into important biological processes but can be logistically difficult to measure in wild populations.

Rescue, rehabilitation, and release of marine mammals: An analysis of current views and practices. [PDF]

open access: yes, 1996
Stranded marine mammals have long attracted public attention. Those that wash up dead are, for all their value to science, seldom seen by the public as more than curiosities.

Investigating the physiological underpinnings of proactive and reactive behavioural types in grey seals (Halichoerus grypus): Trial deployment of a minimally invasive data logger for recording heart rate and heart rate variability in a wild free-ranging breeding pinniped species [PDF]

open access: yes, 2017
Individuals differ non-randomly in their responses to stressors, exhibiting consistent individual differences (CIDs) in behavioural and physiological coping mechanisms commonly referred to as coping styles.
