Survival Rates of the California Sea Lion, Zalophus californianus, in Mexico
Abstract California sea lions (Zalophus californianus) in the Gulf of California have declined by 20% over the past 2 decades. The lack of data on life-history parameters for this species has limited the development of demographic models to assess the status of this population. We estimated age- and sex-specific annual survival probabilities for California sea lions using resighting data on 5 pup cohorts from 1981 to 2006. We modeled apparent survival and resighting probability using age-class, sex, and time as potential explanatory variables. Apparent survival rates varied for different age- and sex-classes. Only survival of pups varied by year (from 0.556 to 0.998). Survival was the same for immature males and females (0.90), but differed by sex for young (males = 0.90, females = 0.97) and old (males = 0.75, females = 0.91) adults. Resighting probabilities varied by time, age-class, and sex. Resighting probabilities were higher for females than for males, and lowest for juveniles. The survival estimates presented here provide practical insight into understanding age- and sex-specific survival rates for California sea lions.
Creativity profile of university and conservatory dance students.
What are dance students' creative potential, Special personality characteristics and preferences for high energy activities? Using standardized and original paper and pencil instruments, comparisons were made among dance students in university and conservatory settings, college students and art students. The results demonstrated that dance students are creative, show strong preference for dynamic figures, and have distinct personality characteristics. The university dance students differed from the conservatory students in several important ways.
