Age-specific vibrissae growth rates: A tool for determining the timing of ecologically important events in Steller sea lions
Lorrie D. Rea,Lorrie D. Rea,Aaron M. Christ,Alison B. Hayden,Vicki K. Stegall,Sean D. Farley,Craig A. Stricker,Jo-Ann E. Mellish,Jo-Ann E. Mellish,John M. Maniscalco,Jason N. Waite,Vladimir N. Burkanov,Vladimir N. Burkanov,Kenneth W. Pitcher +13 more
TL;DR: Estimating the growth rate of vibrissae in fetal, rookery pup, young-of-the-year (YOY), yearling, subadult, and adult SSL found there was high individual variability in these growth rates within each age group.

An animal movement model incorporating home range and habitat selection
TL;DR: A single model is proposed that estimates an animal’s home range and habitat selection parameters within that range while accounting for the inherent autocorrelation in frequently sampled telemetry data.
Stable isotope values in pup vibrissae reveal geographic variation in diets of gestating Steller sea lions Eumetopias jubatus
Rick D. Scherer,Andrew C. Doll,Lorrie D. Rea,Aaron M. Christ,Craig A. Stricker,Briana H. Witteveen,Thomas C. Kline,Carolyn M. Kurle,Michael B. Wunder +8 more
TL;DR: Stable isotope modeling is supported in predicting diet composition in gestat- ing adult female Steller sea lions during winter, using pup vibrissae, and indicates a possible under-representation of soft- bodied prey or prey with fragile skeletons from analyses of data from scats.
Stable carbon and nitrogen isotope trophic enrichment factors for Steller sea lion vibrissae relative to milk and fish/invertebrate diets
Craig A. Stricker,Aaron M. Christ,Michael B. Wunder,Andrew C. Doll,Sean D. Farley,Lorrie D. Rea,David A. S. Rosen,Rick D. Scherer,Dominic J. Tollit +8 more
TL;DR: New TEF estimates are provided for (1) maternal relative to pup vibrissae during both gestation and nursing and (2) adult vibrISSae relative to a complex diet based on an additional 76 animals with an age distribution ranging from 1 to 20 mo.
Spatiotemporal analysis of wolverine Gulo gulo harvest in Alaska
TL;DR: In this paper, the authors reviewed the importance of areas with no or light harvest as potential refugia to maintain a sustainable harvest of wolverines and found that areas with light or no reported harvest also were common and widespread.
