Methods of parentage analysis in natural populations
Adam Jones,William R. Ardren +1 more
TL;DR: This review of the leading techniques in parentage analysis, with a particular emphasis on those that have been implemented in readily useable software packages, should serve as a useful guide to anyone who wishes to embark on the study of parentage.
Journal ArticleDOI
Characterization of 20 highly variable tetranucleotide microsatellite loci for bull trout (Salvelinus confluentus) and cross-amplification in other Salvelinus species
TL;DR: The isolation and development of 20 polymorphic tetranucleotide microsatellite loci for bull trout show greater levels of genetic diversity than other loci previously examined in bull trout.
Journal ArticleDOI
Migratory delay leads to reduced passage success of Atlantic salmon smolts at a hydroelectric dam.
Daniel Nyqvist,Larry Greenberg,Elsa Goerig,Olle Calles,Eva Bergman,William R. Ardren,Theodore Castro-Santos +6 more
TL;DR: In this article, the authors used radiotelemetry to study the functionality of a fish bypass for downstream-migrating wild-caught and hatchery-released Atlantic salmon smolts.
Journal ArticleDOI
Thiamine deficiency in fishes: causes, consequences, and potential solutions
Avril M. Harder,William R. Ardren,Allison N. Evans,Matthew H. Futia,Clifford E. Kraft,J. Ellen Marsden,Catherine A. Richter,Jacques Rinchard,Donald E. Tillitt,Mark R. Christie +9 more
TL;DR: The causes and consequences of thiamine deficiency in fishes, and conservation and management strategies for TDC mitigation ranging from evolutionary rescue to managing for a diverse forage base are reviewed.
Journal ArticleDOI
Spatial patterns of hybridization between bull trout, Salvelinus confluentus, and brook trout, Salvelinus fontinalis in an Oregon stream network
TL;DR: Data presented in this study suggest that relative abundance of brook trout and habitat quality are important factors to consider when evaluating the threat of hybridization to bull trout populations.
