Optimizing Selection of Brown Bear Hair for Noninvasive Genetic Analysis
Wildlife Society Bulletin, 2020 Many wildlife studies use noninvasive survey methods such as barbed wire to obtain hair samples for DNA analysis. If laboratory costs preclude processing all samples, it may be important to know a priori which samples are most likely to yield useful DNA.

Journal of Fish Biology, EarlyView.Abstract Dietary analysis has contributed to our understanding of animal niches, interspecific interactions, community structure and the flow of matter and energy in food webs. We employed three methods of dietary analysis to estimate trophic niche overlap between two peacock bass species, Cichla cataractae and Cichla ocellaris, across sympatric ...

Two Types of cDNAs Encoding Proopiomelanocortin of Sockeye Salmon, Oncorhynchus nerka [PDF]
Zoological Science, 1996 To investigate regulatory mechanisms of proopiomelanocortin (POMC) gene expression in sockeye salmon, we have isolated and characterized cDNAs encoding two types of sockeye salmon POMC, which are referred to as ssPOMC-A and -B. Two types of PCR products were amplified from total RNA of sockeye salmon pituitaries by use of rainbow trout sequences.

Age and length composition of Columbia Basin chinook, sockeye, and coho salmon at Bonneville Dam in 2000 [PDF]
, 2001 In 2000, representative samples of adult Columbia Basin chinook (Oncorhynchus tshawytscha), sockeye (O. nerka), and coho salmon (O. kisutch), populations were collected at Bonneville Dam. Fish were trapped, anesthetized, sampled for scales and biological

Ammonia Quotient in Sockeye Salmon (Oncorhynchus nerka)
, 1978 Ammonia quotients (A.Q., ratio of ammonia excreted to oxygen consumed) were computed from data on daily-fed and starved sockeye salmon (Oncorhynchus nerka).

Fish and Fisheries, Volume 27, Issue 4, Page 813-830, July 2026.ABSTRACT Introductions of species outside their native range, such as pink salmon (Oncorhynchus gorbuscha) in the Laurentian Great Lakes, can serve as unplanned experiments that provide new insights into ecological adaptation. We synthesize available information on the understudied Great Lakes pink salmon invasion and highlight how this case can inform

Fisheries Oceanography, Volume 35, Issue 4, Page 565-579, July 2026.ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

Genetic Analysis of Snake River Sockeye Salmon (Oncorhynchus Nerka), 2003 Technical Report. [PDF]
, 2003 A total of 1720 Oncorhynchus nerka tissue samples from 40 populations were characterized using mitochondrial DNA RFLPs (Restriction Fragment Length Polymorphisms). Analysis of anadromous sockeye populations indicated the historical presence of four major

Evolutionary Applications, 2020 Due to the mediating role of body size in determining fitness, the “bigger‐is‐better” hypothesis still pervades evolutionary ecology despite evidence that natural selection on phenotypic traits varies in time and space.
