Wildlife tourism: Underwater behavioral responses of South American sea lions to swimmers
Contributor(s):: Dans, S. L., Crespo, E. A., Coscarella, M. A.
The aim of the present study was to describe the type of interaction between swimmers and sea lions, during tourist trips, at a small colony in Northern Patagonia, Argentina. Particularly we explored if sea lions would show agonistic behaviors towards people, or behaviors that potentially poses a...
Design solutions to coastal human-wildlife conflicts
Contributor(s):: Meredith Root-Bernstein, Nicolás Arévalo Rosas, Layla P. Osman, Richard J. Ladle
Coastal areas can be a challenge for conservation due to multiple competing land uses including development, tourism, and extractive resource use. These multiple land uses often lead to human-wildlife conflicts. Here we propose that collaboration with industrial designers and architects has the...
California Sea Lions (Zalophus californianus) Can Follow Human Finger Points and Glances
Contributor(s):: Thomas Arkwright, Raphaelle Malassis, Toby Carter, Fabienne Delfour
The aim of this study was to determine whether California sea lions (Zalophus californianus) are capable of using subtle human gestural cues in a series of object choice tests. Four sea lions, housed at Parc Astérix Dolphinarium (Plailly, France), were tested using three gestural cues:...
Galápagos sea lion behavior differences in relation to human exposure
Contributor(s):: Connor M. Piechota, Kevin R. Watson, Ryan J. Fuxa
Our study examined the behavioral differences of the Galápagos sea lion (Zalophus wollebaeki) in relation to human presence. Our main goal was to determine whether sea lions would be more aggressive as a result of high frequencies of human exposure. We hypothesized that sea lions would...
An empirical case study examining effectiveness of environmental enrichment in two captive Australian Sea Lions ( Neophoca cinerea )
Contributor(s):: Smith, B. P., Litchfield, C. A.
This case study examined the effect of environmental enrichment on the activity budgets of a male and female Australian Sea Lion (Neophoca cinerea) housed together at Adelaide Zoo. Using non-food-related (intrinsic) and food-related (extrinsic) enrichment objects, the study conducted an ABABA...

Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain
Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.
Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...

Behavioural responses of juvenile Steller sea lions to hot-iron branding
Contributor(s):: Walker, K. A., Mellish, J. A. E., Weary, D. M.
Here we present the first data showing the post-branding behavioural responses in a marine mammal. Eleven captive juvenile Steller sea lions (Eumetopias jubatus) were observed for 3 days before and 3 days after hot-iron branding. Four of six monitored behaviours changed significantly after...
Serum cortisol in California sea lion pups ( Zalophus californianus californianus )
Contributor(s):: Pedernera-Romano, C., Aurioles-Gamboa, D., Valdez, R. A., Brousset, D. M., Romano, M. C., Galindo, F.
Marine ecosystems are exposed to a wide variety of factors that may produce disturbances in their structure and functioning. The Gulf of California supports fisheries, tourism, intensive agriculture, mining, and more recently, shrimp aquaculture. Under such conditions, animals are forced to cope...
