Long-term patterns in growth of White Sturgeon in the Sacramento-San Joaquin River basin, California.
Introduction: The Sacramento-San Joaquin River system (SSJ) of California includes both riverine, delta, and estuarine habitats and is among the most modified aquatic ecosystems in the United States. Water development projects in the system are associated with declines of many native species, including White Sturgeon Acipenser transmontanus.Methods: We used White Sturgeon pectoral fin...
Linking age and social status of cooperative breeders to vulnerability throughout the harvest season
Individual behaviors are influenced by environmental, genetic, and demographic factors. Some animals choose to live in groups and cooperatively breed, and their behaviors can change depending on dynamic factors such as group size and composition that affect group persistence. In Idaho, USA, gray wolves (Canis lupus) are harvested annually, providing an opportunity to investigate the...
Comparison of lapilli otoliths and pectoral fin rays for estimating age of Northern Pikeminnows
The Northern Pikeminnow Ptychocheilus oregonensis is a piscivorous cyprinid native to western North America. Information on the best structure for estimating the age of Northern Pikeminnows is a key knowledge gap that may limit inquiries on management efforts. Thus, the objective of this study was to evaluate between-reader precision and concordance between age estimates for lapilli...
