Equivalence classification by California sea lions using class-specific reinforcers.
The ability to group dissimilar stimuli into categories on the basis of common stimulus relations (stimulus equivalence) or common functional relations (functional equivalence) has been convincingly demonstrated in verbally competent subjects. However, there are investigations with verbally limited humans and with nonhuman animals that suggest that the formation and use of classification scheme...

A Leptospira species is suspected of being the etiological agenit in a recent epizootic among California sea lions. The disease was confined to subadult males of the species Zalophus c. californianus.
متن کاملAge-specific birth rates of California sea lions (Zalophus californianus) in the Gulf of California, Mexico
Estimates of demographic parameters are essential for assessing the status of populations and assigning conservation priority. In light of the difficulties associated with obtaining such estimates, vital rates are rarely available even for well-studied species. We present the first estimates of age-specific birth rates for female California sea lions (Zalophus californianus) >10 yr of age. Thes...
متن کاملCalifornia Sea Lions Use Dolphins to Locate Food
Aggregations by 3 species of dolphins (the bottlenose dolphin [Tursiops truncatus], the short-beaked common dolphin [Delphinus delphis], and the long-beaked common dolphin [Delphinus capensis]) and California sea lions (Zalophus californianus) were investigated in Santa Monica Bay, California. Groups were followed and observed during 201 boat-based surveys conducted in 1997–2001 documenting tha...
متن کاملClimatic anomaly affects the immune competence of California sea lions
The past decades have been characterized by a growing number of climatic anomalies. As these anomalies tend to occur suddenly and unexpectedly, it is often difficult to procure empirical evidence of their effects on natural populations. We analysed how the recent sea surface temperature (SST) anomaly in the northeastern Pacific Ocean affects body condition, nutritional status, and immune compet...
