Available in PDF, EPUB and Kindle. Book excerpt: Pinnipeds are primarily aged by marks (e.g., flipper tags, brands) applied to individuals when they are of known age (e.g., pups). Age determination is useful for researchers and managers for various reasons including estimating survival rates and assessing mortality of individuals that interact with fisheries. Age can be determined from unmarked animals by extracting a tooth and counting the number of dentine layers. For most populations, however, relatively few individuals are marked and it is often impractical to extract a tooth. Here we developed sex-specific length-age and weight-age curves for the California sea lion (Zalophus californianus). Additionally, we fit a power law curve for an allometric relationship between length and weight. We obtained length and weight measurements from known-age California sea lions captured at various haulout or rookery sites on islands off California and locations in Oregon and Washington. Gompertz and Von Bertalanffy growth models were compared after fitting them to length-at-age (cm) and weight-at-age (kg) data for male and female sea lions from 1 month to age 16 years and 19 years, respectively. The length-at-age data included initial capture and recapture records of female (n = 8,035) and male (n = 5,813) sea lions. The Von Bertalanffy growth curve was a better model than the Gompertz for length- and weight-at-age for both males and females. The weight-at-age relationship was much more variable than for length due to the smaller sample size and the vagaries of seasonal and annual weight loss and gain. However, a linear relationship for weight for ages 3.5-8 months is very reasonable based on the fitted growth curve. [doi:10.7289/V5/TM-AFSC-312 (http://dx.doi.org/10.7289/V5/TM-AFSC-312)]

Whether you knew him as colleague, mentor, friend, family member or simply ‘knew of him’, you could not help but be awestruck by his dedication, intelligence, thoughtfulness, work ethic and passion for scientific inquiry, especially for conservation of the marine environment Many of his publications were seminal in marine mammal health, including infectious, environmental and zoonotic diseases. As we collected manuscripts for this special Frontiers edition, it was heartwarming to hear the comments from contributors. So many research scientists, field biologists and veterinarians could easily have given up and said, ‘I just can’t do this now’, especially with the added challenges posed by the current COVID-19 pandemic. Instead, contributors from around the world were determined to contribute to this collection because of their inspiration and shared commitment with Greg’s vision. The love and admiration within the marine community for Greg is phenomenal. With that said, we would be remiss if we did not say a few words about Greg as a mentor and friend. Greg had a knack for helping students realize their abilities and pursue their own independent contributions to the marine mammal community. He shared in their successes and worked tirelessly to facilitate their aspirations. Greg would involve students, early-career scientists and colleagues in projects, introduce them to collaborators and promote them and their work. Greg was a genuinely caring person. When he asked you ‘how are you doing’, he honestly wanted to know. He was always there, ready to listen and provide guidance. If you were to ask Greg what was most important to him in life, he would say God, family and marine life (and one could argue that he had a special fondness for manatees). He believed in the beauty of nature and that God had a hand in all of it. He was in pursuit of ensuring that we all share this earth responsibly and sustainably. We miss Greg dearly, but honor and celebrate him as we carry on in our pursuits.

With these new unabridged softcover volumes, Wiley hopes to extend the lives of these works by making them available to future generations of statisticians, mathematicians, and scientists. "For both applied and theoretical statisticians as well as investigators working in the many areas in which relevant use can be made of discriminant techniques, this monograph provides a modern, comprehensive, and systematic account of discriminant analysis, with the focus on the more recent advances in the field." –SciTech Book News ". . . a very useful source of information for any researcher working in discriminant analysis and pattern recognition." –Computational Statistics Discriminant Analysis and Statistical Pattern Recognition provides a systematic account of the subject. While the focus is on practical considerations, both theoretical and practical issues are explored. Among the advances covered are regularized discriminant analysis and bootstrap-based assessment of the performance of a sample-based discriminant rule, and extensions of discriminant analysis motivated by problems in statistical image analysis. The accompanying bibliography contains over 1,200 references.
